A DDoS Attack Could Cost $1 Million Before Mitigation Even Starts

A new report suggests that companies are unaware of the extent of the DDoS threat, unaware of the potential cost of an attack, and over-reliant on traditional and inadequate in-house defenses. Marking its inaugural International DDoS Awareness Day, Neustar has released new research into business awareness of contemporary denial-of-service attacks. IDG Research Services questioned more than 200 IT managers for companies with an online marketing or commercial web presence; 70% of which were involved in e-commerce operations. The study finds that it takes an average of ten hours before a company can even begin to resolve a DDoS attack. On average, a DDoS attack isn’t detected until 4.5 hours after its commencement; and a further 4.9 hours passes before mitigation can commence. With outage costs averaging $100,000 per hour, it means that a DDoS attack can cost an internet-reliant company $1 million before the company even starts to mitigate the attack. With the year’s peak shopping period fast approaching, it is something that cannot be ignored. “If an attack results in an outage lasting days, the economic results could be catastrophic. To some companies, it could even be fatal,” warns Neustar. One problem, suggests Susan Warner, Neustar’s market manager for DDoS solutions, is that IT administrators may not be fully aware of the business implications of downtime. “For example,” she says, “an administrator may believe that if the system goes down for a few hours it’s not a big deal, but may not realize there is going to be hundreds of thousand of dollars of marketing spend lost for every hour of site downtime.” A second problem is either a misunderstanding of the nature of modern attacks, or a basic belief that DDoS attacks will always go after someone else. Most companies rely on in-house technology to defend against attacks: 77% have firewalls, 65% have routers and switches, and 59% have intrusion detection. But only 26% use cloud-based mitigation services. Nevertheless, there is a strong belief among these IT managers that they are adequately protected: 86% of the respondents are either somewhat, very or extremely confident in their defenses. But new DDoS techniques such as DNS amplification/reflection, warns Neustar, “can easily overwhelm on-premise defenses and even congest the presumably vaster resources of an ISP.” In fact, in the face of a major attack, in-house defenses can make matters worse. A lot of enterprises, warns Warner, “believe they have some technology already in place that will help them, such as a firewall or a router that can handle some extra traffic, but a high-volume DDoS attack is going to quickly overwhelm those traditional types of defenses and they will rapidly become part of the bottleneck.” “Responding to this new reality,” says the report, “requires actionable continuous monitoring and analysis against realtime threat intelligence, and constantly evolving incident management scenarios.” The answer lies in the cloud. “Cloud-based mitigation is achieved either by redirecting your traffic during an assault or having it always go through a cloud service,” says Warner. “An always-on type of approach can also be achieved through a hybrid solution that provides mitigation resources on-site; if they begin to be overwhelmed, a failover to a cloud service is immediately activated.” Source: http://www.infosecurity-magazine.com/view/35238/a-ddos-attack-could-cost-1-million-before-mitigation-even-starts

Google Project Shield protects “free expression” sites hit by DDoS

Before you ask: this Google’s Project Shield has nothing to do with NVIDIA SHIELD, the two being completely different elements – the Google iteration is all about protecting sites that’d otherwise have little to no protection. Google Project Shield makes with the barrier around a website to stop DDoS (Distributed Denial of Service) attacks to keep sites active. This project has been used to keep up all manner of sites that – before this project – had been taken down by the likes of governments and unfriendly hacker groups. This project has been used for several impressive sites in the recent past, Google aiming to make a much bigger deal of it in the near future. One example is the Persian-language social and political blog Balatarin. Another is quick-access site Aymta, kept up by Google in the face of DDoS attacks recently. This site provides early-warning (somehow or another) of scud missiles to people in Syria. Another example of this project is action is the keeping up of election monitoring service iebc.or.ke during a recent election cycle. Project Shield was responsible for keeping this site up for the first time – it’s stayed up for the entire cycle, that is – in history. Google is currently inviting sites in the following categories to join the initiative – webmasters serving: Independent News Human Rights Elections-Related Content Small independent sites in need of the infrastructure and resources Google is able to supply will be able to apply for help through the main Google Project Shield portal where some very, very simple information is required. Though the site says “invite only”, in this case, Google means that you’ll be invited if your application is accepted. There is also an “Other” category in the “type of content you host on your site” portion of the page in addition to those categories listed above.

DDoS Attacks Grow Shorter But Pack More Punch

If there was ever a riddle asking the listener to name something that has become bigger and shorter at the same time, distributed denial-of-service attacks (DDoS) would be an acceptable answer. According to a new report from Arbor Networks about the third quarter of 2013, the average attack size now stands at 2.64 Gbps for the year, an increase of 78 percent from 2012. The number of attacks monitored by the firm that are more than 20 Gbps experienced massive growth, to the tune of a 350 percent increase so far this year. Meanwhile, the length of the vast majority of attacks (87 percent) has gone down to less than an hour. “Shorter duration attacks are not inherently harder to detect, but they can be harder to mitigate,” says Gary Sockrider, solutions architect for the Americas, Arbor Networks. “Many organizations today rely on network- or cloud-based mitigation of DDoS attacks. Because they rely on rerouting attack traffic to scrubbing centers, there is a small delay in mitigation while routing or domain name changes propagate. “Ideally you want to have mitigation capabilities on your own network that can react immediately without the need for redirection. I think it’s safe to say that if you have absolutely no mitigation capabilities, then shorter attacks are better. However, if your only protection has inherent delays, then shorter attacks potentially cannot be stopped.” Barrett Lyon, founder of DDoS mitigation firm Prolexic Technologies and now CTO of Defense.net, says that shorter DDoS attacks also have the added benefit of minimizing an attacker’s exposure. “The longer it runs, the more things are obviously clogged up and the more reactive network engineers become,” he observes. “When network engineers start researching a problem like that — congestion in their network or why is this computer slow — it exposes the botnet and makes it much vulnerable than it would be otherwise. So if it’s a short attack but big, [attackers] can kind of quickly see and size up their target. They can quickly determine … what’s the best bang for the buck when it comes to attacking.” A clear trend of increasing attack sizes has emerged during the past several years, Sockrider says. “I believe there [is] a combination of factors enabling this trend,” he says. “First, there is increased availability of simple-to-use tools for carrying out attacks with little skill or knowledge. Second, there is a growing proliferation of DDoS-for-hire services that are quite inexpensive. Third, increasingly powerful workstations and servers that get compromised also have significantly faster connections to the Internet from which to generate attacks.” The largest monitored and verified attack size during the quarter was 191 Gbps, according to the firm. Fifty-four percent of attacks this year are more than 1 Gbps, up from 33 percent in 2012. Some 37 percent so far this year are between 2 Gbps and 10 Gbps. Another general trend is of attacks moving to the application layer. In fact, while volumetric attacks are still common, they are now frequently combined with application-layer and state exhaustion attacks, Sockrider says. In some cases, DDoS attacks have served as diversions meant to draw attention from other activities, such as bank fraud. For example, a report published in April by Dell SecureWorks noted how DDoS attacks were launched after fraudulent wire and automatic clearing house (ACH) transfers. “Most people that follow DDoS trends are aware of the really high-profile attacks against government and financial institutions, but in reality the most common targets are actually business and e-commerce sites,” Sockrider says. “We’re also seeing increased attacks in the online gaming industry, where attacks are waged for competitive advantage. Additionally, some organizations are taking collateral damage because they reside in a data center, and they happen to share infrastructure with a high-profile target. The bottom line is that in the current environment, every organization is a potential target.” Source: http://www.darkreading.com/attacks-breaches/ddos-attacks-grow-shorter-but-pack-more/240162741

What Is a DDoS Attack?

What Is a DDoS Attack? Before we can understand just how groundbreaking this recent attack was, let’s first go over exactly what a denial of service attack is. It is one of the least complicated attacks that a hacker can pull off. Basically the goal is to shut down a webserver or connection to the internet. Hackers accomplish this by flooding the server with an extremely large amount of traffic. It would be like taking a wide open freeway and packing it full of the worst rush hour traffic you could imagine. Every connection to and from the freeway would grind to a halt. This would make visiting the website (or the road) next to impossible, or at the least extremely slow! In some cases, the server might overload and shut down completely. When this happens, it doesn’t mean that the website was necessarily hacked. It just means that the website was kicked off the internet for a period of time. This may not sound like that big of a deal, but if your company relies heavily on its online presence, this interruption of service could take a huge cut out of profits. DoS v. DDoS The next item to be clarified is the difference between a DoS (Denial of Service) attack and a DDoS or (Distributed Denial of Service) attack. This distinction is pretty simple: a DoS attack comes from one network or computer whereas a DDoS comes from multiple computers or networks. DDoS attacks are most always bigger than a DoS attack because the strength of the attack can be multiplied by a huge amount of computers.

Preparing for DDoS attacks

Not everyone despaired over the Distributed Denial of Service (DDoS) attacks that hit some of the Web’s biggest e-commerce sites in February. Security consultants and developers of security tools seized the opportunity to spotlight their solutions. Simple DoS attacks are not new. During one, a hacker floods a system with packets of useless requests, making the system so busy it denies access to legitimate users. What’s new are the hacker tools that enable DDoS attacks, in which a hacker uses dozens or hundreds of machines to worsen the attack. The hacker uses client software on one PC to install ‘zombie’ or ‘back door’ programs on other servers, which then flood a target system with useless packets. Zombie programs, including TFN (Tribal Flood Network), Trin00, TFN2K (Tribal Flood Network 2K) and Stacheldraht (Barbed Wire), arrived last fall destined for Solaris, Linux and Windows NT servers. Until recently, most security packages designed to thwart such attacks were aimed at the Unix environment. Now, however, hundreds of programs are being designed for Windows NT, ranging from Internet Security Systems’ (ISS) award-winning SAFEsuite software to BindView Corp.’s free and downloadable Zombie Zapper. Some programs scan the addresses of outgoing messages, intercepting wayward messages before they swamp a potential victim. Others allow administrators to block fake messages from entering a system, or stop the echo functions that help create the constant data flood in a DoS attack. While the programs for NT are good news, the task of evaluating them can easily overwhelm an IS staff, according to Aberdeen Group, a consultancy in Boston. Adding pressure are unresolved issues of liability when one’s computers have been compromised because of lax security. To organize efforts and provide a modicum of legal defense, leading security practitioners suggest these guidelines: Perform a security audit or risk assessment of critical systems using system- and network-based vulnerability tools. Identify and empower an Incident Response Team. Establish an Emergency Response and Escalation Plan. Install Intrusion Detection and Response systems. Examine legal liability exposure. If systems are under attack: Alert your Incident Response Team. Contact your ISP; often, hosts can shut down your access line, stopping the attack. Notify CERT/CC. Notify law enforcement authorities at the FBI and the National Infrastructure Protection Center (NIPC). Monitor systems during the attack using network and host-based intrusion detection systems. Enable detailed firewall logging. Collect forensics to prosecute hackers later. Source: http://networksasia.net/article/preparing-ddos-attacks-960134400

US charges 13 Anonymous members for DDoS attacks

The U.S. has brought criminal charges against 13 persons, said to be members of the hacker group Anonymous, for their alleged participation in cyberattacks as part of a campaign called Operation Payback.The defendants and other members of Anonymous allegedly launched or attempted to launch cyberattacks against government entities, trade associations, individuals, law firms and financial institutions, according to a federal grand jury indictment released Thursday in the U.S. District Court for the Eastern District of Virginia, Alexandria division. Among the organizations targeted were the Recording Industry Association of America, the Motion Picture Association of America, the United States Copyright Office of the Library of Congress, Visa, MasterCard, and Bank of America. The method of attack was DDoS (distributed denial of service) which floods web sites with spurious Internet traffic so that they become unavailable, and the weapon of choice was the freely-available and downloadable network stress testing program known as the Low Orbit Ion Cannon or LOIC, according to the indictment. The 13 persons have been charged with one count of “conspiracy to intentionally cause damage to a protected computer” from about Sept. 16, 2010 to at least Jan. 2, 2011. All are from the U.S. and in their 20s with the exception of Geoffrey Kenneth Commander, a 65-year-old man from Hancock, New Hampshire, and Dennis Owen Collins, a man from Toledo, Ohio born in 1960. Members of Anonymous launched Operation Payback on about September 2010 to retaliate against the discontinuation of The Pirate Bay, a controversial file-sharing website in Sweden, according to the indictment. On December 4, 2010, Operation Payback planned DDoS attacks on the websites of entities that were either critical of whistle-blower website WikiLeaks or had refused to process payments for WikiLeaks, including Amazon and U.S. Senator Joseph Lieberman. The hacker group thereafter launched attacks on the website of PostFinance, a Swiss payments, e-finance, and electronic account management organization, the Swedish prosecutor’s office and a Swedish law firm. This was followed by an attack on the website of MasterCard, which cost the payment firm at least US$5,000 in losses during a one-year period, according to the indictment. Anonymous has attacked sites in the U.S. and abroad for a number of ideological reasons ranging from censorship of the Internet, the takedown of file-sharing site Megaupload, and Israel military action against Hamas.

Schoolboy arrested over Spamhaus DDoS, world’s biggest cyber attack

In March 2013, a distributed denial of service (DDoS) attack of unprecedented ferocity was launched against the servers of Spamhaus, an international non-profit dedicated to battling spam. A DDoS is an attack wherein the servers of a targeted online service are slowed to a crawl with loads of pointless email or file uploads that clog up their processing ability. The March Spamhaus attack peaked at 300 gigabits per second, Spamhaus CEO Steve Linford told the BBC at the time – the largest ever recorded, with enough force to cause worldwide disruption of the internet. In April, one suspect was arrested in Spain. Now, it’s come to light, another suspect was also secretly arrested in April – this one being a London schoolboy. The 16-year-old was arrested as part of an international dragnet against a suspected organised crime gang, reports the London Evening Standard. Detectives from the National Cyber Crime Unit detained the unnamed teenager at his home in southwest London. The newspaper quotes a briefing document on the British investigation, codenamed Operation Rashlike, about the arrest: The suspect was found with his computer systems open and logged on to various virtual systems and forums. The subject has a significant amount of money flowing through his bank account. Financial investigators are in the process of restraining monies. Officers seized his computers and mobile devices. The boy’s arrest, by detectives from the National Cyber Crime Unit, followed an international police operation against those suspected of carrying out the massive cyber attack, which slowed down the internet worldwide. The briefing document says that the DDoS affected services that included the London Internet Exchange. The boy has been released on bail until later this year, the London Evening Standard reports. The arrest follows close on the heels of two other London-based arrests resulting from international cyber-policing: Last week’s arrest of eight men in connection with a £1.3 million ($2.08 million) bank heist carried out with a remote-control device they had the brass to plug into a Barclays branch computer, and The arrest of 12 men in connection with a scheme to boobytrap computers at Santander, one of the UK’s largest banks, by rigging the same type of remote-control device found in Barclays – devices that enable remote bank robbery. Truly, the UK isn’t fooling around when it comes to cybercrime – a fact it’s making clear with the robust work of the National Cyber Crime Unit, which itself will soon be rolled into the even more cybercrime-comprehensive arms of the National Crime Agency. The National Crime Agency, due to launch 7 October, is going to comprise a number of distinct divisions: Organised Crime, Border Policing, Economic Crime, and the Child Exploitation and Online Protection Centre, on top of also housing the National Cyber Crime Unit. If the recent arrests are any indication, it would seem that the UK’s on the right track with cyber crime. May cyber crooks, both the seasoned and the schoolboys, take heed.

Distributed Denial-of-Service Attacks and Midsize Firms

A distributed denial-of-service (DDoS) attack occurs every two minutes, and the number of victims that suffered from more than one attack has risen substantially, according to a new report released by security firm NSFOCUS in SecurityWeek. These attacks are not just high profile any longer, and that is a wake-up call to midsize firms, which are a key target for hackers for many reasons. DDoS Too Often NSFOCUS’s research found that 1.29 DDoS attacks strike somewhere online every two minutes. More than 90 percent of the attacks last less than half an hour. NSFOCUS ascertained that attacks generally remained short and did not go past the rate of 50 Mbps. The number of victims suffering more than one DDoS attack went up 30 percent in just a year, rising to 70 percent. Victims who suffered from only one attack went down from 51 percent last year to 31 percent this year. Interestingly, the study found that hacktivism was the key driver behind more than 91 percent of attacks. Also, online gaming communities and financial services are often targets. What Fuels It The survey also found that a lack of sufficient security, including poor passwords, has fueled the success of DDoS attacks. IT professionals at midsize firms have DDoS attacks on their radar screens since reports in the past few years have shown that the attacks are not just for high-profile purposes. Easily executed attacks that can do the most damage are ideal for today’s cybercriminals; that means midsize firms are at risk. Midsize firms are constantly concerned about having sufficient resources, personnel, money and time to remain competitive, so security must be a top priority for IT professionals, and those who work with third-party data centers should inquire what kind of DDoS protection is provided. Those that manage their own data centers must take the right precautions against botnets and application-layer DDoS attacks on the premises of the network. Also, by working with trusted and experienced security vendors, midsize firms can bring their own security to the next level. When all is said and done, firewalls no longer provide enough protection. A Worthy Investment Distributed denial-of-service attacks are growing, and midsize companies are falling victim. Cybercriminals know that they can successfully hit a lot of growing firms at once and make easy money. They know that some midsize firms do not take security seriously because it might be too costly or time-consuming to consider. In the end, the unprepared midsize firm loses resources, time and money to the costly consequences of a DDoS attack. IT professionals must prioritize security to maintain their company’s competitive edge. Source: http://midsizeinsider.com/en-us/article/distributed-denial-of-service-attacks-an

Lessons Learned From the Banking Industry DDoS Attacks: Good Advice Worth Heeding

Now that the banking industry has gone through four rounds of very public DDoS attacks, experts are looking at what happened to extract some “lessons learned” to turn this negative into a positive. Even if your business isn’t a financial institution, there’s good advice here that’s certainly worth heeding. Lesson One: No matter what industry or business you’re in, you need to have a plan in place to defend your business. DDoS attacks are not just hitting the banking industry. If your business has competitors that would benefit from your website being down, then you are vulnerable. Since it’s possible to buy DDoS as a service, anyone can launch an attack against you for as little as $10. Lesson Two: Don’t wait for an attack to put a solution in place to defend your company. Once an attack starts – and it could happen at any time – your organization’s website could be completely out of commission for an extended period. Why risk downtime when it’s easy enough to put a solution in place today? The solution could be on premise, in the cloud, or a hybrid combination. Lesson Three: Get a dedicated DDoS solution. Don’t count on traditional security devices like firewalls and IDS/IPS to protect your business because they just aren’t designed to handle modern DDoS attacks. When you choose a solution, consider that the volume level of attacks has been getting bigger, and the attacks have grown more sophisticated. Get a solution that meets today’s needs. Lesson Four: Create a detailed incident response plan. Know what to do if/when an attack occurs and assign tasks to specific people to avoid delays in responding. Lesson Five: If your organization is hit by an attack, closely monitor for indicators of compromise (IOCs). Many experts believe that DDoS attacks are smoke screens for fraud and other types of attacks that are designed to steal money or intellectual property. Lesson Six: Be willing to share information. DDoS attacks have been widespread and businesses, solution vendors and law enforcement agencies are better together than individually. If we look at what happened with the banking industry attacks, it got easier to defend against them once all types of organizations collaborated with each other to share intelligence, profiles of the attacks and mitigation strategies. Lesson Seven: This is more of a prediction than a lesson learned. Experts predict that critical infrastructure such as utilities, transportation systems, pipelines, the electrical grid, etc., will be targeted for DDoS attacks at some point. Attackers have the ability to target industrial controls as well as business websites. Administrators who control critical infrastructure need to re-read lessons one through six and take them to heart. Source: http://www.securitybistro.com/?p=8023

DDoS: The Need for Updated Defenses Lessons Learned from a Year of Attacks Against Banks

In the wake of a year of attacks waged against banking institutions by Izz ad-Din al-Qassam Cyber Fighters, the FS-ISAC’s Bill Nelson and the ABA’s Doug Johnson say the need to regularly update DDoS preparedness is a critical lesson learned. As the one-year anniversary of the start of the hacktivists’ distributed-denial-of-service attacks against U.S. banks approaches, banks need to avoid complacency and leverage new mitigation tools to ensure protection against any DDoS attack from any group, the two experts say. By taking advantage of cyber-intelligence and DDoS mitigation toolkits provided by the Financial Services Information Sharing and Analysis Center and others, banking institutions of all sizes can help prevent online outages and mimimize risk for fraud , says Nelson, who heads the FS-ISAC in the U.S. FS-ISAC’s DDoS toolkit, which has been updated three times in the last year, is available to all institutions, not just FS-ISAC members. “We’ve worked to get this out to associations and third-party banking service providers, which really have a very important role as far as DDoS,” Nelson says in an interview with Information Security Media Group. “The Web hosting environment can impact numerous institutions.” A DDoS preparedness plan should address hardware security risks, ensure sufficient bandwidth and outline collaboration with third-party service providers, Nelson says. “Setting up in advance, not just waiting to see your name on a Pastebin post, is critical,” he says. Johnson, who oversees risk management for the American Bankers Association, says institutions have to band together to ensure they have the right plans in place. “It does take that village to ensure the institutions are asking the right questions,” he says. “The threat environment is substantially different than it was before these attacks.” Beyond al-Qassam On Sept. 18, 2012, Izz ad-Din al-Qassam Cyber Fighters announced the launch of its first wave of attacks against U.S. institutions to protest a movie trailer deemed offensive to Muslims. These attacks have forever changed the way the online world approaches DDoS, Nelson says. “When we realized this DDoS attack was different … we realized quickly that we needed to stand up and create an incident response team,” he says. “The reaction was really effective, and it proved how effective information sharing could be.” But Johnson says one lesson the industry has learned over the last year is that DDoS is not just about hacktivism, and banking institutions need to be concerned about attacks from any number of players. “It’s about the broad number of DDoS attacks that the industry is suffering [attacks] from a variety of parties,” he says. For community banks, the greatest concern is not online disruption, but the threat of DDoS attacks being waged to mask fraud, Johnson says.
