Hacked: How Business Is Fighting Back Against the Explosion in Cybercrime

Business is under assault from cybercriminals like never before, and the cost to companies is exploding. Here’s what you need to know about safeguarding your digital assets. 1. Under attack In the summer of 2015, several of New York’s most prestigious and trusted corporate law firms, including Cravath Swaine & Moore and Weil Gotshal & Manges, found themselves under cyberattack. A trio of hackers in China had snuck into the firms’ computer networks by tricking partners into revealing their email passwords. Once inside the partners’ accounts, the thieves snooped on highly sensitive documents about upcoming mergers. Then, from computers halfway around the world, the cybercrooks allegedly traded on the purloined information, netting $4 million in stock market gains. Like most other victims of corporate espionage, the firms preferred to keep mum about having been victimized. They feared antagonizing other digital thugs as well as damaging their reputations as keepers of clients’ secrets. Instead, word of the attack leaked in the press and then was confirmed by federal prosecutors and the firms themselves. The Feds made public their discoveries and trumpeted their efforts to bring the alleged perpetrators to justice. “This case of cyber meets securities fraud should serve as a wake-up call for law firms around the world,” said Preet Bharara, then the U.S. Attorney in Manhattan. “You are and will be the targets of cyberhacking because you have information valuable to would-be criminals.” It may have been a shock to the system for the legal community, but the incident only served to underscore a hard truth that CEOs, company directors, and network security experts have been grappling with for some time now: Business is under assault like never before from hackers, and the cost and severity of the problem is escalating almost daily. The latest statistics are a call to arms: According to Cisco, the number of so-called distributed denial-of-service (DDoS) attacks—assaults that flood a system’s servers with junk web traffic—jumped globally by 172% in 2016. Cisco projects the total to grow by another two and a half times, to 3.1 million attacks, by 2021. Indeed, the pace of cyberassaults is only increasing. Internet security firm Nexusguard reports that it observed a 380% increase in the number of DDoS attacks in the first quarter of 2017 compared with a year earlier. As the number and scale of network attacks grow, the toll on business is rising. The average total cost of a data breach in the U.S. in 2014 was $5.85 million, according to research from IBM and the Ponemon Institute, and this year it’s estimated to be $7.35 million. According to a report earlier this year from business insurer Hiscox, cybercrime cost the global economy more than $450 billion in 2016. The WannaCry ransomware attack alone, which crippled computers in more than 150 countries in May, could cost as much as $4 billion according to some estimates. What is slowly dawning on corporate hacking victims is how vulnerable and defenseless they really are, even when their opponents may be three guys in a room halfway around the world. Expensive data-security systems and high-priced information security consultants don’t faze today’s hackers, who have the resources to relentlessly mount assaults until they succeed. In the New York law-firm case, for example, prosecutors said the attackers attempted to penetrate targeted servers more than 100,000 times over seven months. It has become abundantly clear that no network is completely safe. Where once companies thought they could defend themselves against an onslaught, they’re now realizing that resistance is, if not futile, certainly less important than having a plan in place to detect and neutralize intruders when they strike. But there remains a gaping chasm between awareness of the threat and readiness to address it: A survey last fall by IBM and Ponemon of 2,400 security and IT professionals found that 75% of the respondents said they did not have a formal cybersecurity incident response plan across their organization. And 66% of those who replied weren’t confident in their organization’s ability to recover from an attack. Cybercrime is metastasizing for the same reason online services have become so popular with consumers and businesses alike: Ever-more-accessible technology. Hacking is easier than ever thanks to the ever-growing number of online targets and the proliferation of off-the-shelf attack software. The very Internet networks that were built for convenience and profit are exposing their users to a steady stream of new threats. What’s more, the tense state of affairs is a glaring example of how the entire nature of business has changed in the digital age. In most cases, technology is much more than just a supplement to a company’s core operations. For scores of the world’s most valuable companies—from Alphabet to Amazon to Facebook to Uber—the assets that live on their networks are their core operations. No sector of corporate America is safe. Hackers have plundered big retailers like Neiman Marcus and Home Depot for credit card and customer information. They’ve burrowed into banks like JPMorgan Chase. Even tech companies can’t seem to protect themselves. Yahoo’s ineptitude in repelling (or even being aware of) hackers forced it to reduce its sale price to Verizon. Google and Facebook recently fell victim to a hacker who conned their accountants into wiring him a total of more than $100 million. And OneLogin, a startup that bills itself as a secure password management service, recently lost certain customer data to hackers. In one survey, 66% of security and I.T. professionals replied that they weren’t confident that their organization could recover from a cyberattack. It’s not like companies aren’t trying to play defense. Accenture estimates that companies worldwide spent $84 billion in 2015 to protect against attacks. That spending is an acknowledgment that every company needs to safeguard its digital assets, which in turn requires knowing about the criminals that keep coming at them and what defenses they can build to minimize the damage. 2. A new breed of criminal Hacking is particularly frustrating for corporate executives who don’t understand their enemy. Embezzlers or extortionists? Sure. But faceless gangs of nasty nerds? It’s often harder for CEOs to wrap their brains around the motivation of their antagonists—or their audacity. “At the C-level they feel violated,” says Jay Leek, a venture capitalist pursuing cybersecurity investments and a former chief information security officer at private equity giant Blackstone. “I witness this emotional ‘What just happened?’ You don’t walk in physically to a company and violate it.” The brazenness Leek describes is a hallmark of hackers who—despite their mystique in popular culture—are basically everyday thieves, like bank robbers. Where hackers are different, however, is that they rarely meet in person. Instead, they convene in online forums on the “dark web,” an anonymous layer of the Internet that requires a special browser to access. Deep in the forums, crooks hatch hacking plots of all sorts: breaking into corporate databases or selling stolen Social Security numbers or purchasing inside information from unscrupulous employees. Cybercriminals have proved adept at adopting successful corporate strategies of their own. A recent development has seen the cleverest crooks selling hacking tools to criminal small-fry. It’s analogous to semiconductor companies licensing their technology to device manufacturers. According to a report from security software giant Symantec, gangs now offer so-called ransomware as a service, a trick that involves licensing software that freezes computer files until a company pays up. The gangs then take their cut for providing the license to their criminal customers. If it weren’t all blatantly illegal, the practices would be laudably corporate. “Cybercriminals no longer need all the skills to complete any particular crime,” says Nicole Friedlander, a former assistant U.S. Attorney in charge of the key Southern District of New York’s complex fraud and cybercrime unit. “Instead, they can hire other cybercriminals online who have those skills and do it together.” In that sense, hackers have become service providers like doctors or lawyers or anyone else, says Friedlander, who joined the New York office of law firm Sullivan & Cromwell last year.           Graphic by Nicolas Rapp But the bad guys aren’t all freelancers. In fact, some of the most sinister hacking outfits operating today are “state-sponsored” groups supported, or at least loosely supervised, by governments. That includes the Russians who are believed to have hacked into the Democratic National Committee last year and the North Korean team credited with unleashing the WannaCry malware as a moneymaking scheme. 3. Playing defense In early March, the information security team at ride-hailing giant Uber leaped into action: An Uber employee had reported a suspicious email message, and similar reports were flooding in from all over the company. Uber’s databases contain the email addresses and personal information of millions of riders around the world, making security a particularly pressing issue. And the company has had its share of problems as a caretaker of sensitive data. In 2014, Uber suffered a breach that exposed the insurance and driver’s license information of tens of thousands of drivers; it took the mega-startup months to discover and investigate the incident and fully notify its drivers. As soon as the alarm was raised in March, Uber established an “incident commander” to manage the developing situation. The job of the incident commander—a term of art in cybersecurity circles—is to keep the company informed about potential attacks. It turned out that the attack was targeting users of Google’s Gmail service, not Uber itself. But anyone with a Gmail address was vulnerable. Later that same day Google fixed the vulnerability in its Gmail service, allowing Uber’s incident commander to stand down. Uber’s reaction is an example of the vigilance with which companies must treat the torrent of threats coming at them every day. John “Four” Flynn, a former Facebook executive who now is chief information security officer for Uber, says the key to cybersecurity incidents—which he defines as everything from a data breach to a stolen laptop—is to have a clear communication strategy. “During an incident, the role of executives is to give support,” says Flynn. “There’s no room for confusion about who’s in charge.”           Graphic by Nicolas Rapp   Flynn has every right to sound confident in his authority. The chief information security officer, or CISO, is possibly the hottest job in the C-suite today. Cybercrime is so serious that these formerly little-known and unloved executives now typically have a direct line to boards of directors—a big break from the past. Before, the CISO would report to the chief information officer, who was responsible for buying and operating computers, not obsessing over flies in the ointment. If the CISO sounded the alarm over a breach, too often he or she ended up being the one sacrificed to appease top management. “It was my job to tell my boss his baby was ugly,” one former information security executive laments. These days, though, smart companies treat hacking threats like other existential risks to their business—recessions, terrorist attacks, and natural disasters come to mind—and plan accordingly. The CISO is pivotal in maintaining readiness. “If you’re a Fortune 500 company, you already have a response,” says Leek, the former executive at Blackstone, which had several portfolio companies that suffered breaches, including arts-and-crafts merchant Michaels Stores. “But people forget to take it out, blow the dust off, and recall: ‘Let’s do what we decided when we had a sound mind.’ ” Having a clear line of authority and a good action plan take a company only so far. At some point it has to call the cops, specifically the Federal Bureau of Investigation or the U.S. Secret Service. Both agencies have reach and power that allow them to take the fight to foreign cybercrooks. On several occasions, U.S. law enforcement agents working undercover on the dark web have managed to lure presumed offenders out of hiding with phony deals, and then had them apprehended in and extradited to the U.S. During the incident, the role of executives is to give support,” says Uber’s chief information officer. “There’s no room for confusion about who’s in charge.” Calling law enforcement has downsides, however. The likely outcome—an investigation—imposes burdens on the victim company in terms of money and time. And it increases the chance that sensitive details about the hack will leak publicly. That’s why the best course of action is for companies to avoid FBI-level hacking incidents in the first place. A new, multibillion-dollar industry has sprung up to help. 4. An industry is born The videoconference camera looked like any other. But unbeknownst to its corporate owner, the device was working overtime: Hackers had captured the microphone remotely and were using it to spy on every meeting that took place in the boardroom. The company, which does not want to be identified, finally got wise to the spying scheme thanks to Darktrace, a global cybersecurity company that uses artificial intelligence to detect aberrant activity on client networks. Darktrace CEO Nicole Eagan says her company noticed the camera had been gobbling abnormal amounts of data. This raised a red flag, enabling Darktrace to notify its client that something was amiss. Darktrace is just one of hundreds of firms that offer help to combat the hacking epidemic. Once a stodgy corner of enterprise software, cybersecurity has become a hot sector for venture capitalists. Investors put some $3.5 billion into a total of 404 security startups last year, according to New York research firm CB Insights. That’s up from $1.8 billion for 279 investments in 2013.           Graphic by Nicolas Rapp   For executives, all of this entrepreneurial activity translates into a dizzying array of security options. There are newcomers like Tanium, for instance, which offers a service that lets companies see who is on their network. Publicly traded Palo Alto Networks makes a kind of intelligent firewall that uses machine learning to thwart intruders. There are also a host of niche security firms such as Area 1 (which specializes in defending against phishing scams) and Lookout (which is a mobile-phone-focused security service). With all of this firepower arrayed against it, how can cybercrime continue to grow so fast? One answer is that some of the glitzy defense systems don’t work as advertised. Security insiders grumble about firms bamboozling clients with “blinky lights” in order to sell “scareware”—software that plays to customers’ insecurities but doesn’t protect them. At the end of the day, though, humans are as much to blame as software. “The weak underbelly of security is not tech failure but poor process implementation or social engineering,” says Asheem Chandna, an investor with Greylock Partners and a Palo Alto Networks director. Chandna notes that most hacking attacks come about in two ways, neither of which involves a high level of technical sophistication: An employee clicks on a booby-trapped link or attachment—perhaps in an email that appears to be from her boss—or someone steals an employee’s log-in credentials and gets access to the company network. While cyberdefense tools can mitigate such attacks, some will always succeed. Humans are curious creatures and, in a big organization, there will always be someone who clicks on a message like, “Uh-oh. Did you see these pictures of you from the office party?” When it comes to hacking, a penny of offense can defeat a dollar’s worth of defense. That’s why the fight against hacking promises to be a never-ending battle.   Source: https://fortune.com/2017/06/22/cybersecurity-business-fights-back/

Final Fantasy 14 is experiencing DDoS attacks

Trouble logging in? It may be due to hackers Final Fantasy 14’s servers have been under intense strain this past weekend. It now seems that these issues are the direct result of distributed denial-of-service attacks, Square Enix stated today. The attacks have apparently been going on since June 16, the first day that the game’s second expansion, Stormblood, went live for early access. This past weekend, early adopters were met with congested servers that were filled to capacity. Some queues just to log in surpassed 6,000 users. In the game proper, overwhelmed servers have lead to increased load times and made some quests impossible to complete. Stormblood was officially released yesterday and as of today, massive amounts of access requests due to the alleged hack are continuing to occur. Square Enix has stated that its technicians are doing all they can to defend against the attacks, but they are “continuing to take place by changing their methods at every moment.” The company also assured players that character data and private information associated with accounts have not been affected.

Risk Management Pros Say an IoT Security Incident Could Be Catastrophic

A recent survey by the Ponemon Insitute and the Shared Assessments Program of 553 people with a role in risk management in their organizations found that 94 percent of those surveyed said a security incident related to unsecured IoT devices or applications could be catastrophic. Still, just 44 percent of respondents said their organization has the ability to protect their network or enterprise systems from risky IoT devices, and only 25 percent said their boards require assurances that IoT risks are being appropriately assessed, managed and monitored. Additionally, 77 percent of respondents said they don’t consider IoT-related risks in their third party due diligence, and 67 percent don’t evaluate IoT security and privacy practices before engaging in a business relationship. Just 30 percent of respondents said managing third-party IoT risks is a priority in their organization. “Ready or not, IoT third party risk is here,” Shared Assessments senior vice president Charlie Miller said in a statement. “Given the proliferation of connected devices, today’s cyber climate is evolving and organizations have to shift their focus to the security of external parties, now more than ever.” “In order to avoid becoming the next big headline, our security tactics have to evolve along with the threats,” Miller added. “New technology and practices are needed to ensure security, and this starts by communicating the risks to the right people and acknowledging potential devastating outcomes when engaging with a third party. Avoiding these problems can no longer be the solution.” Preventative Measures In response, the report urges organizations to take the following key steps: Ensure inclusion of third-party and IoT risks occurs at all governance levels including the board. Update asset management processes and inventory systems to include IoT devices, and understand the security characteristics of all inventoried devices. When devices are found to have inadequate security controls, replace them. Continue to leverage and enhance contracts and policies and expand scope to include IoT specific requirements. Expand third-party assessment techniques and processes to ensure presence and effectiveness of controls specific to IoT devices. Develop specific sourcing and procurement requirements to ensure only IoT devices that are designed with security functions included and enabled are considered for product selection or acquisition. Devise new strategies, technologies and tactics directed specifically at reducing threats posed by IoT devices. Collaborate with industry experts, peers, associations and regulators to ensure IoT risk management best practices are devised, communicated and implemented. Include IoT in communication, awareness and training at all levels: board, executive, corporate, business unit and third-party. Recognize the increasing dependence on technology to support the business and the risk posed by this dependence. Embrace new technologies and innovations, but not at the expense of security, and ensure security controls are included as fundamental and core requirements. Seventy-two percent of respondents said the pace of innovation in IoT and the varying standards for security make it hard to ensure the security of IoT devices and applications, and 65 percent said the drive for innovation in the IoT ecosystem requires new approaches to IT strategies and tactics. Breaches and DDoS Attacks Strikingly, 78 percent of respondents said a data breach involving an unsecured IoT device is likely to occur within the next two years, and 76 percent said the same of a DDoS attack involving an unsecured IoT device. The concerns come as DDoS attacks become more and more frequent — according to Nexusguard’s Q1 2017 DDoS Threat Report, DDoS attack frequency surged by 380 percent in the first quarter of 2017, compared to the same time period the previous year. The percentage of days with attacks larger than 10 Gbps rose significantly between January 2017 (48.39 percent) and March 2017 (64.29 percent). Radware vice president of security Carl Herberger told eSecurity Planet by email that the rapid proliferation of unsecured IoT devices is driving the increase in DDoS attacks. “The Mirai attack made headlines last year, but it should not be considered a one-off,” he said. “Instead, this event was a predictor of what is to come.” “Hackers are constantly developing new ways to leverage connected devices with little to no security protections to form larger and larger botnets that are able to execute dangerous and sizable DDoS attacks,” Herberger added. “We’ve seen various botnets appear over the last year, including Hajime, BricketBot and Persirai, demonstrating that IoT devices have become a new battleground for hackers.” “Until manufacturers, the government, and consumers take a hard look at IoT security, the threat of bigger, more frequent IoT-fueled DDoS attacks will only loom larger,” Herberger said.

DDOS Attacks on the Rise

Distributed Denial of Service (DDoS) attacks leverage compromised devices to generate a flood of traffic, overwhelming online services and rendering them unresponsive. DDoS services are widely available on the internet, with research by Trend Micro finding that the small cost of US$150 can buy a DDoS attack for a week. (It also brings organised crime into your life – but that’s a different point!) The latest statistics from Cisco reveal that the number of DDoS attacks grew by 172% in 2016. Combine this with an average DDoS attack size of 1.2Gbps, capable of taking most organisations offline, and there is real cause for concern among cyber security experts. It is hard to trace DDoS attacks to their proprietors, as the majority of devices used in attacks belong to innocent users. Organisations must understand the risk and impact posed by DDoS attacks, and implement mitigation strategies that promote business continuity in the face of these attacks. Industry peers must share knowledge where appropriate, and keep government agencies adequately informed, to deter hackers from launching a DDoS attack. Cisco expects that the number of DDoS attacks in the future will only get worse, with 3.1 million predicted attacks in 2021 globally. Source: http://www.natlawreview.com/article/ddos-attacks-rise

DDOS Attacks on the Rise

Bigger & smaller – DDoS threats here to stay with conflicting trends

The noise created by distributed denial of service attacks is higher than ever – with vendors and attackers complicating the picture – but what do enterprises need to worry about? Distributed Denial of Service (DDoS) attacks were one of the most talked about threats at InfoSecurity Europe 2017. One of the things vendors couldn’t agree on however, is the trend for their size and thus whether we should be defending against increasing numbers of small attacks or more frequent mega-attacks. Corero Network Security, who met with SC during the conference, said in a press release that, “the greatest DDoS risk for organisations is the barrage of short, low volume attacks which mask more serious network intrusions”. Research from the firm says that “despite several headline-dominating, high-volume DDoS attacks over the past year, the vast majority (98 percent) of the DDoS attack attempts against Corero customers during Q1 2017 were less than 10 Gbps per second in volume.” It added: “they are just disruptive enough to knock a firewall or intrusion prevention system (IPS) offline so that the hackers can target, map and infiltrate a network to install malware and engage data exfiltration activity.” Ashley Stephenson, CEO at Corero Network Security, explains: “Short DDoS attacks might seem harmless, in that they don’t cause extended periods of downtime. But IT teams who choose to ignore them are effectively leaving their doors wide open for malware or ransomware attacks, data theft or other more serious intrusions. Just like the mythological Trojan Horse, these attacks deceive security teams by masquerading as a harmless bystander – in this case, a flicker of internet outage – while hiding their more sinister motives.” DDoS protection has traditionally been something that major enterprises were able to deploy by having their traffic run through a supplier network at huge cost. The alternative was to switch traffic over to their DDoS protection provider in the event of an attack – but this could cause a delay of about 20 minutes while the company under attack found who to call and explain what was happening, the whole time that the attack was escalating. Instead, Laurent Gil, co-founder at Zenedge, explained to SC Media UK how his company’s approach to DDoS protection is different. “We have an always-on monitoring system on the cloud so there is nothing to install for the customer, it’s the same SSL as an ‘always on’ solution, but always on in the cloud for monitoring and analysing of traffic patterns and when the early signs of an attack are spotted, we automatically re-route traffic to our scrubbing centre within 60 seconds – down from the 20 minutes it takes non-automated systems,” Gil told SC. He added that because the traffic only switched on demand, when there is an attack, it is less cost than if it had to be handled all the time and with a 60 second response, it still mitigated against the attack ramping up. “It’s a tectonic shift in the market,” says Gil, adding, “We we can onboard many more enterprises, without them spending millions of dollars, which is what’s needed for a for mid-market enterprise. DDoS protection did not exist for these companies because they couldn’t afford it. It’s not that the traditional prime protection providers are losing revenues, but the market is much wider now than it was previously.” In contrast to Corero, veteran vendor Imperva, hosted sessions which could be misconstrued as ‘humble-brags’ named “how we stopped a 650Gbps DDoS attack over lunch”. Imperva points out that the source code of the Mirai botnet going open source has meant that the Tools, Tactics and Procedures (TTP) of botnet criminals have taken a step up. And naturally, it is prepared to protect against this threat with one of it’s “behemoth” data centre appliances. Imperva’s Robert Hamilton, director of product marketing, hosted the sessions and said “DDoS attacks aren’t going away anytime soon”. Raj Samani, chief scientist of Mcafee told SC: “The number is completely subjective. When we saw the beginnings of DDoS as an extortion tactic it was brushed off since the throughput wasn’t significant enough to worry most enterprises, then all of a sudden the firepower increased to in excess of 50Gbps. Whilst this number for many organisations can be easily managed (as we saw with DDoS providers withstanding 620Gbps attacks), the reality is that the firepower of DDoS attacks are on the up. What is the magic number that will cause concern? Well, it will be whatever hasn’t been tested against!” That may be the case, but then Akamai, another DDoS protection giant says in its Q1 2017 State of the Internet report that “the mega attacks are outliers that represent the limits enterprises must be prepared to defend against. However, the overwhelming number of smaller attacks means that these mega attacks have little impact on the trend lines that defend the median attack size, which is a better indicator of what an organisation is most likely to see.” Akamai raises another important point: the rise in use of IoT devices which are compromised for malicious use – such as using an “internet-enabled toaster to mine bitcoins” – are likely to end up contributing to harsher DDoS attacks as these devices are eventually recruited into the mega-botnets which carry out such attacks. A new report from Kaspersky Lab, also released after InfoSec, shows that when organisations are attacked by a DDoS, “customer-facing resources suffer more in banking, than in any other sector.” “For example, 49 per cent of banks that have suffered a DDoS attack have had their public website affected (compared to 41 percent of non-financial institutions) and 48 percent have had their online banking affected when they’ve been targeted by DDoS.” “Recovering from DDoS is also more expensive for banks than non-financial organisations. The report shows that a DDoS incident can cost a financial institution US$ 1,172,000 (£917,427) to recover from, compared to US$ 952,000 (£745,000) for businesses in other sectors.” Kirill Ilganaev, head of Kaspersky DDoS Protection, Kaspersky Lab said in a press release, “In the banking sector reputation is everything, and security goes hand-in-hand with this. If a bank’s online services come under attack, it is very difficult for customers to trust that bank with their money, so it’s easy to see why an attack could be so crippling. If banks are to protect themselves effectively from the price tag of an online banking cybersecurity incident, they first need to become more prepared for the dangers DDoS attacks pose to their online banking services. This threat should be featuring higher on banks’ security priorities.” Kaspersky Lab is encouraging financial institutions to share security intelligence to be better prepared for dealing with the threat of an attack on their online banking services.

Bigger & smaller – DDoS threats here to stay with conflicting trends

DDoS attacks continue to morph

According to Bryan Hamman, territory manager for sub-Saharan Africa at Arbor Networks, while reflection and amplification techniques have come to characterise a large number of complex, multi-vector DDoS attacks, the latest approach is to use reflection to exploit connection-less lightweight directory access protocols (CLDAPs). Traditionally, large attacks based on reflection or amplification were the likes of NTP, DNS, SNMP, SSDP, SQL RS or Chargen. “But this new trend has now been discovered ‘in the wild’, with the force to generate highly efficient and destructive results,” he says. What is CLDAP? CLDAP is essentially a computer networking protocol designed for legitimate users to query and modify stored data on X.500 directory systems. It is typically used on Windows Exchange servers and domain controllers. By providing directory and access control, one can use CLDAP to locate printers on a network, find a phone number of an employee, or see the security groups a user belongs to, for instance. The modus operandi involves the attacker spoofing the source of a connectionless protocol, pinging the server with ultra-small queries. The server then responds to the victim with a far larger response. Initial findings suggest that this approach can amplify the initial response in the region of 46 to 55 times the size. “This makes CLDAP attacks highly efficient. A well-orchestrated attack that exploits an organisation’s vulnerabilities could very quickly achieve massive total attack size, and bring down the digital systems of all but the largest and best-protected organisations.” Primary targets Reports* from cloud giant Akamai show that the largest example of CLDAP reflection as the sole vector resulted in a payload of 52 bytes, amplified to as much as 70 times in this case – creating an attack data payload of 3,662 bytes, a peak bandwidth of 24Gbps, and 2 million packets per second. CLDAP attacks have primarily targeted the software and technology industry. Other industries targeted include internet and telecom, media and entertainment, education, retail and consumer goods, and financial services. Fighting back To effectively resist this type of DDoS attack, organisations need to thoroughly address the potential threat at a network level, by covering a number of bases: Prevent abuse: Ensure that you have anti-spoofing deployed at the edges of your networks. Detect attacks: Leverage flow telemetry exported from all network edges to Arbor technology, to automatically detect, classify, traceback, and alert on DDoS attacks. Ready mitigation techniques: Deploy network infrastructure-based reaction/ mitigation techniques such as Source-Based Remotely-Triggered Blackholing (S/RTBH) and flowspec at all network edges. Mitigate attacks: Deploy intelligent DDoS mitigation systems at strategic points within your network. Minimise damage: Deploy Quality-of-Service (QoS) mechanisms at all network edges to police CLDAP traffic down to an appropriate level. Remediate CLDAP services: Proactively scan for and remediate abusable CLDAP services on the ISP and customer networks to reduce the number of abusable CLDAP servers. “Like many other reflection techniques, organisations must always have ingress filtering in place. Unless there is a real need for your firm to have CLDAP available over the internet, you shouldn’t expose this protocol,” concludes Hamman.

US Blames North Korea For Series Of DDoS Attacks

The Department of Homeland Security and the Federal Bureau of Investigation issued a rare cybersecurity bulletin linking North Korea to a series of attacks that have targeted global businesses and critical infrastructure since 2009. The alert focuses on a malware strain called DeltaCharlie, which DHS and FBI say was used by the North Korean government to launch distributed denial of service attacks. DDoS attacks use floods of web traffic from compromised devices to knock websites or services offline. North Korea targeted “the media, aerospace, financial, and critical infrastructure sectors in the United States and globally,” the alert says. The US government refers to North Korea’s hacking team as Hidden Cobra, but cybersecurity firms often use the slightly less sinister name Lazarus Group. The North Koreans have also been linked to the WannaCry ransomware that spread virally in May and shut down hospitals and businesses. WannaCry primarily targeted unpatched Windows machines, and it sounds like the Lazarus Group’s DDoS malware is also primarily exploiting devices that run old versions of Windows. “The multiple vulnerabilities in these older systems provide cyber actors many targets for exploitation,” the alert notes. Windows typically stops issuing patches for older operating systems after they have been retired, but the company today released patches that thwart WannaCry on outdated devices, ZDNet reports. Although DHS and FBI released data that will help detect and mitigate Lazarus Group attacks, the agencies said more research is necessary to “understand the full breadth” of the group’s capabilities.

DDoS attacks hitting ‘record-breaking’ levels as volumes increase 380%

DDoS attackers are hitting hard, fast and with no breaks in between, leading to record-breaking attacks over hours or even days, according to Nexusguard’s Q1 2017 Threat Report. Those record-breaking attacks over Valentine’s Day, Chinese New year and other ‘typically quiet’ periods during the season. “In APAC, a lengthy attack January 28-31, the period of Chinese New Year, lasted 2 days, 19 hours, and 40 minutes. It was a widespread, disruptive event that left celebrants weary and exhausted upon returning to work,” the report says. DDoS attack volumes have also risen 380% since the same time last year, according to Nexusguard’s statistics, based on 16,600 attacks. While 51% of attacks lasted fewer than 90 minutes, 4% exceeded 1440 minutes. 77.3% of attacks were less than 10Gbps, while 20% were between 10-200Gbps and 2% exceeded 200Gbps. The United States, China and Japan rounded out the top three sources for attacks. The rest of APAC was relatively unused as an attack source. However it’s not just DDoS attacks that are on the rise: HTTP flood attacks jumped 147% in the last quarter alone. It is now one of the leading volumetric attacks, exceeding both TCP and DNS attacks. The company cites the Internet of Things as a major weak point, particularly as the range of insecure devices and connections expodes. DDoS attacks can be persistent and long-lasting, which is a major area of concern. “IoT botnets are only the beginning for this new reign of cyber attacks. Hackers have the scale to conduct gigantic, continuous attacks; plus, teams have to contend with attacks that use a combination of volumetric and application aspects,” comments Nexusguard’s CTO Juniman Kasman. Those attacks are not happening in isolation. 93% of attacks combine application and volumetric vulnerabilities. Multiple DDoS attacks can also overwhelm systems. The company warns that organisations that haven’t invested in – or haven’t upgraded – multi-layered defense mechanisms run the highest risk of attack exposure. “This early data for 2017 shows that enterprises need to employ multi-layered defenses that use nimble resources, including large, redundant scrubbing networks and around-the-clock security operations if they hope to keep from drowning in the deluge of new attacks,” Kasman adds.

DDoS attacks hitting ‘record-breaking’ levels as volumes increase 380%

Ten steps for combating DDoS in real time

To the uninitiated, a distributed denial-of-service (DDoS) attack can be a scary, stressful ordeal. But don’t panic. Follow these steps by David Holmes, senior technical marketing manager: Security, F5 Networks, to successfully fight an attack: If you appear to be suffering a volumetric attack, it helps to have a historical sense of your own traffic patterns. Keep a baseline of normal traffic patterns to compare against. If you have determined that you are under a DDoS attack, record the estimated start time in your attack log. Monitor volumetric attacks. Remember to keep a monitoring web page open to indicate when the attack may be over (or mitigated). You will need to follow (up to) 10 steps for your DDoS mitigation: Step 1: Verify the attack Not all outages are caused by a DDoS attack. DNS misconfiguration, upstream routing issues, and human error are also common causes of network outages. You must first rule out these types of non-DDoS attacks and distinguish the attack from a common outage. · Rule out common outages: The faster you can verify the outage is a DDoS attack, the faster you can respond. Even if the outage was not caused by a misconfiguration or other human error, there may still be other explanations that resemble a DDoS attack. · Check outbound connectivity: Is there outbound connectivity? If not, then the attack is so severe that it is congesting all inbound and outbound traffic. Check with your usual diagnostic tools (such as traceroute, ping, and dig) and rule out all such possibilities. · Rule out global issues: Check Internet weather reports, such as Internet Health Report and the Internet Traffic Report, to determine if the attack is a global issue. · Check external network access: Attempt to access your application from an external network. Services and products that can perform this kind of monitoring include: Keynote testing and monitoring, HP SiteScope agentless monitoring, SolarWinds NetFlow Traffic Analyzer, and Downforeveryoneorjustme.com. · Confirm DNS response: Check to see if DNS is responding for your website. The following UNIX command resolves a name against the OpenDNS project server: % dig @208.67.222.222 yourdomain.com Step 2: Contact team leads. Once the attack is verified, contact the leads of the relevant teams. If you have not filled out any quick reference sheets or a contact list, create one now or use our templates. When an outage occurs, your organisation may hold a formal conference call including various operations and applications teams. If your company has such a process in place, use the meeting to officially confirm the DDoS attack with team leads. · Contact your bandwidth service provider: One of the most important calls you can make is to the bandwidth service provider. List the number for your service provider in your contact sheet. The service provider can likely confirm your attack, provide information about other customers who might be under attack, and sometimes offer remediation. · Contact your fraud team: It is especially important to invoke the fraud team as soon as the attack is verified. DDoS attacks can be used as cover to hide an infiltration. Logs that would normally show a penetration may get lost during a DDoS attack. This is why high-speed, off-box logging is so important. Step 3: Triage applications Once the attack is confirmed, triage your applications. When faced with an intense DDoS attack and limited resources, organisations have to make triage decisions. High-value assets typically generate high-value online revenue. These are the applications you will want to keep alive. Low-value applications, regardless of the level of legitimate traffic, should be purposefully disabled so their CPU and network resources can be put to the aid of higher-value applications. You may need the input of team leads to do this. Ultimately, these are financial decisions. Make them appropriately. Create an application triage list; it takes only a few minutes to fill one out, and will greatly assist in making tough application decisions while combating an actual DDoS event. Decide which applications are low priority and can be disabled during the attack. This may include internal applications. Step 4: Protect partners and remote users. · Whitelist partner addresses: Very likely you have trusted partners who must have access to your applications or network. If you have not already done so, collect the IP addresses that must always be allowed access and maintain that list. You may have to populate the whitelist in several places throughout the network, including at the firewall, the Application Delivery Controller (ADC), and perhaps even with the service provider, to guarantee that traffic to and from those addresses is unhindered. · Protect VPN users: Modern organisations will whitelist or provide quality-of-service for remote SSL VPN users. Typically this is done at an integrated firewall/ VPN server, which can be important if you have a significant number of remote employees. Step 5: Identify the attack Now is the time to gather technical intelligence about the attack. The first question you need to answer is “What are the attack vectors?” There are four types of DDoS attack types, these are · Volumetric: flood-based attacks that can be at layers 3, 4, or 7; · Asymmetric: designed to invoke timeouts or session-state changes; · Computational: designed to consume CPU and memory; and · Vulnerability-based: designed to exploit software vulnerabilities. By now you should have called your bandwidth service provider with the information on your contacts list. If the attack is solely volumetric in nature, the service provider will have informed you and may have already taken steps at DDoS remediation. Even though well-equipped organisations use existing monitoring solutions for deep-packet captures, you may encounter cases where you have to use packet captures from other devices, such as the ADC, to assist in diagnosing the problem. These cases include: SSL attack vectors and FIPS-140. Step 6: Evaluate source address mitigation options If Step 5 has identified that the campaign uses advanced attack vectors that your service provider cannot mitigate (such as slow-and-low attacks, application attacks, or SSL attacks), then the next step is to consider the following question: “How many sources are there?” If the list of attacking IP addresses is small, you can block them at your firewall. Another option would be to ask your bandwidth provider to block these addresses for you. · Geoblocking: The list of attacking IP address may be too large to block at the firewall. Each address you add to the block list will slow processing and increase CPU. But you may still be able to block the attackers if they are all in the same geographic region or a few regions you can temporarily block. The decision to block entire regions via geolocation must be made as a business decision. Finally, if there are many attackers in many regions, but you don’t care about any region except your own, you may also use geolocation as a defence by blocking all traffic except that originating from your region. · Mitigating multiple attack vectors: If there are too many attackers to make blocking by IP address or region feasible, you may have to develop a plan to unwind the attack by mitigating “backwards”; that is, defending the site from the database tier to the application tier, and then to the web servers, load balancers, and finally the firewalls. You may be under pressure to remediate the opposite way; for example, mitigating at layer 4 to bring the firewall back up. However, be aware that as you do this, attacks will start to reach further into the data centre. Step 7: Mitigate specific application attacks If you have reached this step, the DDoS attack is sufficiently sophisticated to render mitigation by the source address ineffective. Tools such as the Low Orbit Ion Cannon, the Apache Killer, or the Brobot may generate attacks that fall into this category. These attacks look like normal traffic at layer 4, but have anomalies to disrupt services in the server, application, or database tier. To combat these attacks, you must enable or construct defences at the application delivery tier. Once you have analysed the traffic in Step 4, if the attack appears to be an application-layer attack, the important questions are: Can you identify the malicious traffic? Does it appear to be generated by a known attack tool? Specific application-layer attacks can be mitigated on a case-by-case basis with specific F5 counter-measures. Attackers today often use multiple types of DDoS attack vector, but most of those vectors are around layers 3 and 4, with only one or two application-layer attacks thrown in. We hope this is the case for you, which will mean you are nearly done with your DDoS attack. Step 8: Increase application-level security posture. If you have reached this step in a DDoS attack, you’ve already mitigated at layers 3 and 4 and evaluated mitigations for specific application attacks, and you are still experiencing issues. That means the attack is relatively sophisticated, and your ability to mitigate will depend in part on your specific applications. Asymmetric application attack: Very likely you are being confronted with one of the most difficult of modern attacks: the asymmetric application attack. This kind of attack can be: · A flood of recursive GETs of the entire application. · A repeated request of some large, public object (such as an MP4 or PDF file). · A repeated invocation of an expensive database query. Leveraging your security perimeter: The best defence against these asymmetric attacks depends on your application. For example, financial organisations know their customers and are able to use login walls to turn away anonymous requests. Entertainment industry applications such as hotel websites, on the other hand, often do not know the user until the user agrees to make the reservation. For them, a CAPTCHA (Completely Automated Public Turning test to tell Computers and Humans Apart) might be a better deterrent. Choose the application-level defence that makes the most sense for your application: A login wall, human detection or real browser enforcement. Step 9: Constrain resources. If all the previous steps fail to stop the DDoS attack, you may be forced to simply constrain resources to survive the attack. This technique turns away both good and bad traffic. In fact, rate limiting often turns away 90 to 99 percent of desirable traffic while still enabling the attacker to drive up costs at your data centre. For many organisations, it is better to just disable or “blackhole” an application rather than rate-limit it. · Rate shaping: If you find that you must rate-limit, you can provide constraints at different points in a multi-tier DDoS architecture. At the network tier, where layer 3 and layer 4 security services reside, use rate shaping to prevent TCP floods from overwhelming your firewalls and other layer 4 devices. Connection limits: Connection limits can be an effective mitigation technique, but they do not work well with connection-multiplexing features. Application tier connection limits should provide the best protection to prevent too much throughput from overwhelming your web servers and application middleware. Step 10: Manage public relations Hacktivist organisations today use the media to draw attention to their causes. Many hacktivists inform the media that an attack is underway and may contact the target company during the attack. Financial organisations, in particular, may have policies related to liability that prevent them from admitting an attack is underway. This can become a sticky situation for the public relations manager. The manager may say something like, “We are currently experiencing some technical challenges, but we are optimistic that our customers will soon have full access to our online services.” Journalists, however, may not accept this type of hedging, especially if the site really does appear to be fully offline. In one recent case, a reporter called a bank’s local branch manager and asked how the attack was proceeding. The branch manager, who had not received media coaching, responded, “It’s awful, we’re getting killed!” If the DDoS attack appears to be a high-profile hacktivist attack, prepare two statements: · For the press: If your industry policies allow you to admit when you are being externally attacked, do so and be forthright about it. If policy dictates that you must deflect the inquiry, cite technical challenges but be sure to prepare the next statement. · For internal staff, including anyone who might be contacted by the press: Your internal statement should provide cues about what to say and what not to say to media, or even better, simply instruct your staff to direct all inquiries related to the event back to the PR manager. Include a phone number. Anton Jacobsz, managing director at Networks Unlimited, a value-adding reseller of F5 solutions throughout Africa, notes that it is the organisations focusing on a holistic security strategy that are considered forward-looking and ahead of the digital economy curve. “In a digital age – where sensitive or personal information is at risk of being exposed, and where geo-location and sensor-based tools track movements – organisations need to be prepared for a cyber attack. It has become essential to scrutinise security throughout the entire operation and offerings in order to build the strongest cornerstones for establishing trust between company, employees and consumers,” says Jacobsz.

If You Learn of DDoS Attacks from Customers, You’ve Already Failed

If your customers notice something’s wrong before your own security specialists do, you’ve failed on multiple levels When Benjamin Franklin said, “Time is money,” he gave the world an aphorism that would be quoted frequently by businesspeople for more than 200 years. For all his wit and insight, of course, Franklin could never have foreseen the many scenarios for which his pithy observation would come to apply. It turns out that among the most relevant applications of the quote in today’s digitally driven world is in the realm of cybersecurity. Why? Because for organizations that suffer a cyberattack, a slow response can prove very costly. In an early 2017 survey of more than 1,000 IT and business decision makers, nearly two-thirds of the respondents said they could lose $100,000 per hour or more if a distributed denial of service (DDoS) attack were to disrupt their peak business periods. On the bright side, 8 in 10 of the organizations responding to the Neustar-sponsored survey said they’ve learned about new DDoS attacks from their internal security and IT teams – at least sometimes. Less encouraging is the fact that 40% also said they have, at times, received their first notification of attacks from their customers. If your customers notice something’s wrong before your own security specialists do, you’ve failed on multiple levels. The ideal DDoS defense is to recognize an emerging threat and neutralize it before it even gains a foothold – and certainly before your customers experience any negative impacts. If customers start complaining about an inability to access your websites or other services, you’ve already started to lose money before you’re even aware of the problem. Beyond causing staggering monetary losses for many corporations, successful DDoS attacks can alienate customers and shake their confidence in the victim’s ability to secure its own systems. By extension, customer then worry about the security of their own interactions with the company, and about the safety of any customer data the company may hold. The resulting customer churn and reduced loyalty can result in additional financial consequences. In this regard, another Franklin quote sadly holds true: “It takes many good deeds to build a good reputation, and only one bad one to lose it.” Fortunately, there are many security tools and services available to organizations that decide to be proactive in their DDoS defenses. As is often the case when it comes to cybersecurity, the most effective defenses will leverage a layered approach. The first-level of defense for DDoS attacks ideally will be provided by the network or Internet service provider, which is often the first to see – and block – suspicious network activity. For those attacks that still manage to get through, companies need their own DDoS identification and mitigation solutions. Some of those solutions may be on-premises appliances and other controls, while others may be provided by cloud-based or managed security services providers. Such “security-as-a-service” offerings are rapidly gaining in popularity, especially if an attack’s scale exceeds the capabilities of the on-premises protections. In short, there’s little excuse to be reactive, rather than proactive, when it comes to DDoS defenses. And, yes, Franklin once again provides some sage advice to those who may be too cavalier in their attitudes about DDoS threat. “By failing to prepare, you are preparing to fail.” Source: http://www.csoonline.com/article/3200084/leadership-management/if-you-learn-of-ddos-attacks-from-customers-you-ve-already-failed.html
