Top Banks Offer New DDoS Attack Details

Increasingly, U.S. banking institutions are reluctant to acknowledge – much less discuss – the ongoing distributed-denial-of-service attacks against their online services. Perhaps that’s because they’re concerned that consumers will panic or that revealing too much about the attacks could give hacktivists information they could use to enhance their DDoS abilities. But in recent regulatory statements, the nation’s largest banks are candid about DDoS attacks and their impact. In their annual 10-K earnings reports, filed with the Securities and Exchange Commission, seven of the nation’s top 10 financial services institutions provide new details about the DDoS attacks they suffered in 2012. In its report, Citigroup even acknowledges that DDoS attacks have led to unspecified losses. Citigroup , which filed its 10-K report March 1, notes: “In 2012, Citi and other U.S. financial institutions experienced distributed-denial-of-service attacks which were intended to disrupt consumer online banking services. While Citi’s monitoring and protection services were able to detect and respond to these incidents before they became significant, they still resulted in certain limited losses in some instances as well as increases in expenditures to monitor against the threat of similar future cyber-incidents.” The bank also points out that these attacks are being waged by powerful adversaries. “Citi’s computer systems, software and networks are subject to ongoing cyber-incidents, such as unauthorized access; loss or destruction of data (including confidential client information); account takeovers; unavailability of service; computer viruses or other malicious code; cyber-attacks; and other events,” Citi states. “Additional challenges are posed by external extremist parties, including foreign state actors, in some circumstances as a means to promote political ends.” When contacted by BankInfoSecurity , Citi and other institutions did not comment further about DDoS attacks or the information in the 10-K reports. These banks, as well as other U.S. financial institutions, are now in the midst of the third wave of DDoS attacks attributed to the hacktivist group Izz ad-Din al-Qassam Cyber Fighters – a group that has claimed since September that its attacks are being waged to protest a YouTube movie trailer deemed offensive to Muslims. ‘Technically Sophisticated’ In their 10-K reports, Citi, as well as JPMorgan Chase & Co. , Bank of America , Goldman Sachs Group , U.S. Bancorp , HSBC North America and Capital One acknowledge suffering from increased cyber-activity, with some specifically calling out DDoS as an emerging and ongoing threat. HSBC North America, in its 10-K report filed March 4, notes the global impact of DDoS on its customer base. “During 2012, HSBC was subjected to several ‘denial of service’ attacks on our external facing websites across Latin America, Asia and North America,” the bank states. “One of these attacks affected several geographical regions for a number of hours; there was limited effect from the other attacks with services maintained. We did not experience any loss of data as a result of these attacks.” And U.S. Bank, in its 10-K filed Jan. 15, describes DDoS attacks as “technically sophisticated and well-resourced.” “The company and several other financial institutions in the United States have recently experienced attacks from technically sophisticated and well-resourced third parties that were intended to disrupt normal business activities by making internet banking systems inaccessible to customers for extended periods,” U.S. Bank reports. “These ‘denial-of-service’ attacks have not breached the company’s data security systems, but require substantial resources to defend and may affect customer satisfaction and behavior.” U.S. Bank reports no specific losses attributed to DDoS, but it states: “Attack attempts on the company’s computer systems are increasing, and the company continues to develop and enhance its controls and processes to protect against these attempts.” Other DDoS Comments Here is what the other institutions reported about DDoS attacks suffered in 2012: Chase: “The firm and several other U.S. financial institutions continue to experience significant distributed denial-of-service attacks from technically sophisticated and well-resourced third parties which are intended to disrupt consumer online banking services. The firm has also experienced other attempts to breach the security of the firm’s systems and data. These cyber-attacks have not, to date, resulted in any material disruption of the firm’s operations, material harm to the firm’s customers, and have not had a material adverse effect on the firm’s results of operations.” BofA: “Our websites have been subject to a series of distributed denial of service cybersecurity incidents. Although these incidents have not had a material impact on Bank of America, nor have they resulted in unauthorized access to our or our customers’ confidential, proprietary or other information, because of our prominence, we believe that such incidents may continue. Although to date we have not experienced any material losses relating to cyber-attacks or other information security breaches, there can be no assurance that we will not suffer such losses in the future.” CapOne: “Capital One and other U.S. financial services providers were targeted recently on several occasions with distributed denial-of-service attacks from sophisticated third parties. On at least one occasion, these attacks successfully disrupted consumer online banking services for a period of time. If these attacks are successful, or if customers are unable to access their accounts online for other reasons, it could adversely impact our ability to service customer accounts or loans, complete financial transactions for our customers or otherwise operate any of our businesses or services online. In addition, a breach or attack affecting one of our third-party service providers or partners could impact us through no fault of our own. Because the methods and techniques employed by perpetrators of fraud and others to attack, disable, degrade or sabotage platforms, systems and applications change frequently and often are not fully recognized or understood until after they have been launched, we and our third-party service providers and partners may be unable to anticipate certain attack methods in order to implement effective preventative measures. Should a cyber-attack against us succeed on any material scale, market perception of the effectiveness of our security measures could be harmed, and we could face the aforementioned risks. Though we have insurance against some cyber-risks and attacks, it may not be sufficient to offset the impact of a material loss event.”   No Mentions of Attacks Among the top 10, the only institutions that do not specifically reference DDoS in their 10-K reports are Morgan Stanley, Bank of NY Mellon and Wells Fargo , a bank that has recently suffered significant online outages. Wells Fargo spokeswoman Sara Hawkins tells BankInfoSecurity that the bank’s online and mobile-banking channels were inaccessible for portions of the day on April 4, when it saw “an unusually high volume of website and mobile traffic … which we believe is a denial of service attack.” Reporting Protocol Doug Johnson , who oversees risk management policy for the American Bankers Association, says banking institutions are required to report all suspicious cyber-activity either through their filings with the SEC or in the Suspicious Activity Reports to the Financial Crimes Enforcement Network , a bureau of the U.S. Department of the Treasury. All financial institutions, regardless of size, must report SARs to FinCEN, an agency that collects, analyzes and shares financial intelligence. However, only companies with more than $10 million in assets are required to file reports with the SEC. Banking institutions are required to report cyber-attacks in their SEC filings, Johnson says. “Online banking platforms, obviously, are extremely important to banking retail consumers, and so that would be one of those systems which would be very important to report on a suspicious activity report,” Johnson says. “One thing that is also very important to do is to go and have that conversation with your primary federal regulator, at the field level, to find out what you would do, as an institution, for generalized security breach reporting.” Breach reporting requirements vary from state to state, Johnson adds.

Lessons Learned in Historic DDoS Attack on Spamhaus

The DNS amplification vulnerability, which was exploited to the fullest in the attacks on Spamhaus, return incoming requests to a DNS server with as much as 100 times as much data. When the attackers have faked the source address for those incoming requests, the responses can overwhelm the victims’ servers — and possibly spill over and clog the Net. What is the aftermath of the massive Distributed Denial of Service attacks recently on the anti-spam Spamhaus organization? As the largest such attack in history, the digital assault on Spamhaus slowed network performance in some regions of Europe and elsewhere, raised alarms about whether the Net could reach a breaking point, and has become a historic event that could mark a turning point. According to reports in The New York Times and elsewhere, a key figure in the attacks appears to be Sven Olaf Kamphuis, who is associated with CyberBunker, the Dutch hosting facility where the attacks originated. After the Europe-based Spamhaus put CyberBunker on its spam blacklist, because of what Spamhaus said were substantial streams of spam e-mails coming from that hosting facility, the DDoS attacks began. Kamphuis maintains a Facebook page, in which he champions hosting services such as CyberBunker for providing open Net access, and he rails against Spamhaus for acting like an arbitrary authority. Like ‘The Mafia’ CyberBunker has said it will allow customers to host anything except “child porn and anything related to terrorism.” Spamhaus is backed by a variety of e-mail services, and experts have testified in court that many e-mail services would be rendered useless by the flood of spam if not for the organization’s efforts. But this massive wave of DDoS attacks — in which Web servers are overwhelmed by a flood of bogus traffic — broke some boundaries, according to Garth Bruen, an adviser to the consumer-oriented Digital Citizens Alliance. Bruen told USA Today that the attacks from CyberBunker were like “the kind of things we saw the mafia do to take control of neighborhoods 50 years ago.” He added that what was particularly “troubling” is that CyberBunker is a commercial ISP “working with shadowy figures in undisclosed locations.” Open DNS Resolvers The attacks have highlighted some ongoing weaknesses in the Internet’s infrastructure . Key among these are open Domain Name System resolvers, which allow attackers to engage in so-called DNS amplification. One of the weaknesses of open resolvers is that they do not authenticate a sender’s address before replying. This vulnerability, which was exploited to the fullest in the attacks on Spamhaus, return incoming requests to a DNS server with as much as 100 times as much data . When the attackers have faked the source address for those incoming requests, the responses can overwhelm the victims’ servers — and possibly spill over and clog other parts of the Net. DNS servers are critical to the Internet as they translate alphanumeric-based Web addresses like “www.google.com” into the numeric IP addresses that computers can understand. The Spamhaus attacks reportedly utilized more than 30,000 unique DNS resolvers. There are efforts, such as the Open DNS Resolver Project, to convince DNS administrators to implement source address validation, among other actions, to eliminate open DNS resolvers as a Net-wide weakness. There are also calls for IT departments and individual PC owners to make a greater effort to scan their computers for signs of malware that could be hijacking their machines into becoming part of a botnet. Additionally, the Electronic Frontier Foundation and others have offered tips to small businesses on how to cope with DDoS attacks, if their sites become one of the direct or indirect targets.

Seal with Clubs goes down due to DDoS Attack

Bitcoin poker site, Seals with Clubs, was twice targeted by a Distributed Denial of Service (DDoS) attack this weekend – forcing it offline for three days. It is not known why the US-facing poker site was targeted for the DDoS attacks – in which multiple computer systems overload a single web site with incoming traffic – or who was responsible. The first attack started on Thursday evening (local time) when the site became inaccessible to regular players while those who were already logged in found that their games stalled and then the site crashed. Seal with Clubs´ CEO Bryan Micon was quick to re-assure players on the site that no accounts had been compromised and the Seals with Clubs Twitter account kept clients up to date with the progress of “Seal Team 6” as the site battled to get the software transferred to a new data centre. However, shortly after getting up and running on Sunday, Seals with Clubs was hit by a second, smaller DDoS attack which knocked out all the Sunday feature tournaments on the site. Protection Implemented Against Further Attacks [The first attack] was a large DDoS, very sophisticated and quite powerful enough to knock everything off, get an IP blackholed, all that good stuff, Micon said in a statement to PokerFuse.com. We have quickly, in the middle of the weekend, changed datacenters and have a new, beefier setup with all of our data intact and a sick DDoS protection layer. New software has also been integrated into the Seals with Clubs downloadable client to add further protection, and players have been advised that they will have to update their existing software to enable them to play on Seals with Clubs. An update to the Seals with Clubs Android App is also expected later today (Monday). The Seals are Back By late Sunday evening, Seals with Clubs was back online and saw more than 300 players on the cash game tables with several low-value tournaments under way. Due to the change of data centres, players who recently deposited into their accounts may have to wait until Monday to see the funds appear in the cashier; however facilities for getting Bitcoin funds out of players´ accounts are operating normally with withdrawal requests dealt with in a matter of hours. Players who were involved in poker tournaments at the time of the DDoS attack have been told that they will receive “generous refunds” in respect of their tournament buy-ins.
