39% of businesses not ready to protect themselves against DDoS

Companies are not ready to protect themselves against DDoS, with four in ten (39%) businesses unclear about the most effective protection strategy to combat this type of attack, according to research from Kaspersky Lab. A lack of knowledge and protection is putting businesses at risk of grinding to a halt. DDoS attacks can quickly incapacitate a targeted business’s workflow, bringing business-critical processes to a stop. However, the research found that nearly a fifth (16%) of businesses are not protected from DDoS attacks at all, and half (49%) rely on built-in hardware for protection. This is not effective against the increasing number of large-scale attacks and ‘smart’ DDoS attacks which are hard to filter with standard methods. Large-scale cyberattacks are now commonplace, such as the recent attack on telecommunications provider StarHub, which faced a high-profile DDoS attack in October last year. Hackers are also showing a preference for DDoS attacks, with the proliferation of IoT devices today. As IoT devices have weak security protocols, they are easy targets for hackers to launch DDoS attacks from. As IoT devices are forecasted to hit 21 billion in 2020, each potential entry point into an organisation increases vulnerability to DDoS attacks. Many businesses are in fact aware that DDoS is a threat to them – of those that have anti-DDoS protection in place, a third (33%) said this was because risk assessments had identified DDoS as a potential problem, and one in five (18%) said they have been attacked in the past. For some, compliance, rather than awareness of the security threat, is the main driver, with almost half (43%) saying regulation is the reason they protect themselves. The problem for businesses is that, in many cases, they may assume they’re already protected. Almost half (40%) of the organizations surveyed fail to put measures in place because they think their Internet service provider will provide protection, and one in three (30%) think data center or infrastructure partners will protect them. This is also not always effective, because these organizations mostly protect businesses from large-scale or standard attacks, while ‘smart’ attacks, such as those using encryption or imitating user behavior, require an expert approach. Moreover, the survey found that a third (30%) fail to take action because they think they are unlikely to be targeted by DDoS attacks. Surprisingly, one in ten (12%) even admit to thinking that a small amount of downtime due to DDoS would not cause a major issue for the company. The reality is that any company can be targeted because such attacks are easy for cybercriminals to launch. What’s more, the potential cost to a victim can reach millions. “As we’ve seen with the recent attacks, DDoS is extremely disruptive, and on the rise,” says Kirill Ilganaev, Head of Kaspersky DDoS Protection at Kaspersky Lab. “When hackers launch a DDoS attack, the damage can be devastating for the business that’s being targeted because it disables a company’s online presence. As a result business workflow comes to a halt, mission-critical processes cannot be completed and reputations can be ruined. Online services and IT infrastructure are just too important to leave unguarded. That’s why specialized DDoS protection solution should be considered an essential part of any effective protection strategy in business today.” Source: http://www.networksasia.net/article/39-businesses-not-ready-protect-themselves-against-ddos.1486046674

The emergence of new global cybercriminal attack patterns

The findings of a new Malwarebytes report illustrate a significant shift in cybercriminal attack and malware methodology from previous years. Ransomware, ad fraud and botnets, the subject of so much unjustified hype over previous years, surged to measurable prominence in 2016 and evolved immensely. Cybercriminals migrated to these methodologies en masse, impacting nearly anyone and everyone. To better understand just how drastically the threat landscape evolved in 2016, researchers examined data taken from Windows and … More ?

Get ready for the cyber war in 2017: know your enemy

The current state of the cyber security industry is troubling to say the least, with 2016 experiencing a greater number of successful, more vicious cyber attacks than ever before The past few months have summed up the current state of the cyber security industry. In a matter of days at the end of November the European Commission was brought offline by a distributed denial-of-service (DDoS) attack, San Francisco’s Municipal Railway was held to ransom by ransomware in a system-wide attack and it was revealed that in September the Japanese Defence Ministry and Self-Defence Forces were hacked, which may have compromised Japan’s internal military network. It seems almost farcical, and from these recent examples it is evident that critical infrastructure is totally unprepared for an attack and will continue to be severely vulnerable at the beginning of 2017. It is not just the public sector that is suffering, with private organisations facing daily hacking attacks despite serious investment in cyber security strategies. The problem is inherently twofold. The first is that cyber criminals and their tactics are constantly evolving, becoming more overwhelming and hard to detect by the day, it seems. The ferocity of cyber attacks was illustrated last year by the Mirai botnet n(or Dyn) attacks that overran a number of systems using corrupted Internet of Things (IoT) devices. When the malicious code was first published online in October, it gave a suspected group of teenagers the ability to shut down the likes of Twitter and Spotify. In the preceding month, Liberia’s internet was taken offline using the same code. Improving the security of IoT devices will be crucial during 2017. This is where the most devastating cyber attacks will originate. Source: http://www.information-age.com/get-ready-cyber-war-123464202/

53% of service providers are seeing over 21 DDoS attacks per month

More than half (53 percent) of service providers indicated they are seeing more than 21 DDoS attacks per month, up from 44 percent last year. New research from Arbor Networks’ 12th Annual Worldwide Infrastructure Security Report (WISR) focuses on the operational challenges internet operators face daily from network-based threats and the strategies adopted to address and mitigate them. The survey polled 356 respondents that included services providers, hosting, mobile, enterprise and other types of network operators around the world. Since the WISR began in 2005, DDoS attack size has grown 7900 percent. Attacks increased by 60 percent in 2016. Twenty-one percent of data centre respondents saw more than 50 attacks per month, as opposed to only eight percent last year. More than 10 attacks per month were experienced by 45 percent of enterprise, government and education (EGE) respondents. Two-thirds (67 percent) of service providers and 40 percent of EGE respondents reported seeing multi-vector attacks on their networks. Sixty-one percent of data centre operators reported attacks totally saturating data centre bandwidth. A quarter of data centre and cloud providers saw the cost of a major DDoS attack rise above £79,000, and five percent cited costs of over £793,000. Forty-one percent of EGE organisations reported reportedDDoS attacks exceeding their total internet capacity. Nearly 55 percent of EGE respondents now carry out DDoS defence simulations, with about 40 percent carrying them out at least on a quarterly basis. Data centre and cloud provider respondents using firewalls for DDoS defence has fallen from 71 percent to 40 percent. “The survey respondents have grown accustomed to a constantly evolving threat environment with steady increases in attack size and complexity over the past decade. However, IoT botnets are a game changer because of the numbers involved. There are billions of these devices deployed, and they are being easily weaponised to launch massive attacks. Increasing concern over the threat environment is reflected in the survey results, which show significant improvements in the deployment of best practice technologies and response processes,” said Darren Anstee, chief security technologist at Arbor Networks.

Hong Kong securities brokers hit by cyber attacks, may face more: regulator

HONG KONG (Reuters) – Hong Kong’s securities regulator said brokers in the city had suffered cyber attacks and warned of possible further incidents across the industry. Regulators in Hong Kong have been stepping up efforts over the past year to combat the growing menace of cyber attacks on companies. A survey in November showed the average number of such attacks detected by firms in mainland China and Hong Kong grew a whopping 969 percent between 2014 and 2016. [nL4N1DU35T] In a circular to licensed firms late on Thursday, the Securities and Futures Commission (SFC) said it had been informed by the Hong Kong police that brokers had encountered so-called “distributed denial of service” (DDoS) attacks targeting their websites and received blackmails from criminals. “The DDoS attacks have caused service disruption to the brokers for a short period. It is possible that similar cyber security incidents would be observed across the securities industry,” the SFC said in the notice. Distributed denial of service (DDoS) attacks, among the most common on the Internet, involve cyber criminals using hijacked and virus-infected computers to target websites with data requests, until they are overwhelmed and unable to function. The SFC urged firms in the financial center to implement protective measures, including reviews of the IT systems and DDoS mitigation plans.

South Korean authorities worry about DDoS attacks ahead of elections

A new report from a South Korean government agency, the country is at risk of DDoS attacks ahead of the country’s possible election. South Korean authorities are reportedly worried about ramped up attacks from the country’s hostile northern neighbour. A recently released report predicted DDoS attacks, leveraging IoT botnets, would be used to attack government ministries. Authored by the state-run Korea Internet & Security Agency (KISA), the report warns of DDoS attacks just before the country’s upcoming elections. The attacks, which leverage widely insecure IoT devices, could be launched against government ministry, national infrastructure or social bodies to destabilise South Korea. Jeon Kil-soo, from KISA told South Korean news agency, Yonhap, that “there is the possibility that huge DDoS attacks could occur by using IoT devices from both home and abroad”. Kil-soo added that such attacks could be deployed against presidential candidates. Current president Park Geun-hye is currently faced with an impeachment motion, which, if adopted by Korea’s Constitutional Court, will trigger another election. The decision is expected to be made in the next two months. According to KISA’s report, such an occasion would be ripe for exploitation by, some expect, North Korea. South Korea are not the only country bracing themselves for cyber-interference in upcoming elections. Against a backdrop of accusation of Russian interference in the American election, top government officials from Germany, France and other countries have expressed fears about such threats. North Korea’s cyber-offensive activities have long been suspected. The North Korean government was reported to be behind the attacks on Sony Pictures on the eve of the 2014 release of The Interview, a comedy which satirised the country’s leader Kim Jong Un. In November 2014, Sony Pictures Entertainment was breached by a group calling itself the “Guardians of Peace”. The hackers released a slew of emails, personal information and other data from inside the company, prompting sanctions against the country. North Korean agents are also suspected to be behind the heist on the Bangladesh Central Bank. In early 2016, hackers stole US$81 million (£65 million) by impersonating legitimate money orders. The money was then laundered through Sri Lanka and the Philippines into the coffers of, some suspect, the North Korean government. This kind of activity takes on a new light when applied to South Korea. South and North Korea have technically been at war since the middle of the twentieth century. Split in two against the backdrop of the Cold War, the countries fought a war between 1950 and 1953. The war never technically ended and the countries remain separate with a Chinese backed opaque dictatorship under the Kim Jong family in the north and a liberal democratic regime in the south. The two countries exist in a state of formal hostility, and while not effectively at war are believed to regularly meddle in each other’s societies, the cyber-realm included. James Hoare, an associate fellow at Chatham House and the man formerly charged with setting up a British embassy in North Korea, “the report is all very speculative, with nothing much in the way of hard facts.” There are many such claims about North Korean cyber-attacks, “including claims of interference with aircraft landing at Inchon airport – though having watched the behaviour of people on flights into and from Inchon, I would not be surprised if some of the alleged attacks were in reality people on their mobile devices while the planes are taking off and landing.” These kinds of claims are common but “tend to be somewhat unspecific, but on at least one recent occasion, the North Korean released information that indicated that they had been approached to stage some sort of diversion at the time of an election.” Source: https://www.scmagazine.com/south-korean-authorities-worry-about-ddos-attacks-ahead-of-elections/article/633651/

Global concern over distributed denial-of-service attacks

Arbor Networks has released its 12th Annual Worldwide Infrastructure Security Report (WISR). The report covers a range of issues from threat detection and incident response to managed services, staffing and budgets. But the main focus is on the operational challenges internet operators face daily from network-based threats and the strategies adopted to address and mitigate them. The largest distributed denial-of-service (DDoS) attack reported this year was 800 Gbps, a 60% increase over 2015’s largest attack of 500 Gbps. According to Arbor, DDoS attacks are not only getting larger, but they are also becoming more frequent and complex. Darren Anstee, chief security technologist with Arbor Networks, says survey respondents have grown accustomed to a constantly evolving threat environment with steady increases in attack size and complexity over the past decade. “However, IoT botnets are a game changer because of the numbers involved – there are billions of these devices deployed and they are being easily weaponised to launch massive attacks,” he says. “Increasing concern over the threat environment is reflected in the survey results, which show significant improvements in the deployment of best practice technologies and response processes. The report also found that the emergence of botnets that exploit inherent security weaknesses in IoT devices and the release of the Mirai botnet source code have increased attacker ability to launch extremely large attacks. According to the company, the massive growth in attack size has been driven by increased attack activity on all reflection/amplification protocols, and by the weaponisation of IoT devices and the emergence of IoT botnets. Because of this, Arbor say the consequences of DDoD attacks are becoming clear – DDoS attacks they have successfully made many leading web properties unreachable – costing thousands, sometimes millions, of dollars in revenue. However, the company does point out that this year’s survey results indicate a better understanding of the brand damage and operational expense of successful DDoS attacks.

Defeating DDoS attacks in the Cloud: Why hosting providers need to take action

DDoS attacks have become such a significant threat that hosting providers need to actively protect against them or risk their own reputations. In the first few days of the New Year, hosting provider 123-reg was once again hit by a distributed denial of service (DDoS) attack, leaving customers unable to access their websites and email accounts. Even though the magnitude and strength of the attack weren’t as immense as the 30Gbps attack on the website in August last year, it still raises availability and security concerns and emphasises the importance of using effective DDoS mitigation systems. 123-reg reacted with remediation procedures and was able to get services back up and running within a couple of hours, but not after customers experienced service outages and latency issues. Successful DDoS attacks hit more than just network infrastructure, brand reputation and bottom line suffer greatly. For many providers, just a handful of customers make up a significant portion of their revenue stream. Losing one or more of these key accounts would be detrimental to the business. With no shortage of DDoS attacks hitting the news headlines, many businesses that operate in the cloud or plan to move their business applications to the cloud, are beginning to review their DDoS protection options, and the capabilities of their providers. Hosting Providers and DDoS Threats The sheer size and scale of hosting provider network infrastructures and their massive customer base presents an incredibly attractive attack surface due to the multiple entry points and significant aggregate bandwidth that acts as a conduit for a damaging and disruptive DDoS attack. As enterprises increasingly rely on hosted critical infrastructure or services, they are placing themselves at even greater risk from these devastating cyber threats – even as an indirect target. The Domino Effect The multi-tenant nature of cloud-based data centres can be less than forgiving for unsuspecting tenants. For example, a DDoS attack that targets one organisation within the data centre can have disastrous repercussions for other tenants, causing a domino effect of latency issues, service degradation and potentially damaging and long-lasting service outages. The collateral damage associated with successful DDoS attacks can be exponential. When providers lack proper protection mechanisms to defeat attacks in real-time, the costs associated with the outages are wide ranging and the impact to downstream or co-located customers can be devastating. Therefore, if hosting providers are not protected and do not provide effective DDoS mitigation as a part of their service offering, they may inadvertently send useless and potentially harmful traffic across their customers’ networks. Traditional Defences Do Not Work Traditional techniques of defence such as black-hole routing are a crude response to DDoS attacks. Using this method, a hosting provider blocks all packets of website traffic destined for a domain by advertising a null route for the IP address under attack. The most notable issue with this approach, is when multiple tenants share a public IP address. In this situation, all customers associated with the address under attack will lose all service, regardless of whether they were a specific target of the attack. In effect, by using this method, the data centre operator is carrying out the wishes of the attacker, by taking their customers offline. Black-hole routing is not an approach that most operators prefer – since it completely took their customers offline. A more sophisticated approach was then introduced; instead of injecting a null route when an operator observed a large spike, they would inject a new route instead. That action redirected all good and bad traffic through an appliance or bank of appliances that inspected traffic and attempted to remove the attack traffic from the good traffic flows. This approach spawned the existence of DDoS scrubbing-centers with DDoS scrubbing-lanes commonly deployed today. However this approach still required a considerable amount of human intervention. A DDoS attack would have to be detected (again by analyzing NetFlow records) then an operator would have to determine the victim’s destination IP address(s). Once the victim was identified, a BGP route update would have to take place to inject a new route to “turn” the victim’s incoming traffic to where a scrubbing lane was deployed. The appliances in the scrubbing lane would attempt to remove the DDoS traffic from the good traffic and forward it to the downstream customer. Effective DDoS Defence The weaknesses of old methods – being slow to react, expensive to maintain and unable to keep up with shifting and progressive threats – tell us that solutions appropriate for today need to be always-on and remove the attack traffic in real-time, without damaging other customers, or dropping good user traffic. It’s clear they also need to be adaptable and scalable so that defences can be quickly and affordably updated to respond to the future face of DDoS threats – whatever those may be. The increasingly popular method of fulfilling these aims is through real-time DDoS mitigation tools installed directly at the peering point, meaning customer traffic can be protected as it travels across an organisation’s entire network. Such innovations mean providers are better positioned than ever before to offer effective protection to their customers, so that websites and applications can stay up and running, uninterrupted and unobstructed. Hosting providers are starting to deploy this technology as part of their service package to protect their customers. This maximises efficiency due to the fact that defences can be constantly on, with no need for human intervention. Providers can tune these systems so that customers only get good traffic, helping their sites run far more efficiently. It’s a win-win for both sides, as providers’ services become more streamlined and reliable, protecting their reputation, and attracting more customers in the process. Hosting providers have a golden opportunity to modernise their services in this way, and generate new channels for revenue – or else, they risk a slow shrinking of their customer base.
