Lessons From 5 Advanced Attacks Of 2013

Distributed denial-of-service attacks targeted application and business-logic weaknesses to take down systems; fraudsters used encryption to scramble victims’ data until they paid a ransom; and, attackers increasingly targeted providers as a weak link in the chain of the digital security protecting businesses. In 2013, there were no major revolutions in the way that attackers compromised, cut off, or just plain inconvenienced their victim’s systems, but their techniques and tactics evolved. From more pernicious encryption in ransomware to massive DDoS attacked fueled by reflection, attackers showed that they still had options available in their bag of tricks. “As the criminals have become more savvy and more technically knowledgable and understand the victims’ environments better, they are able to see opportunities that they might otherwise overlook,” says Jeff Williams, director of security strategy for the counter threat unit at Dell SecureWorks, a managed security provider. Based on interviews with experts, here are five advanced attacks from 2013 and the lessons for businesses from those events. 1. Cryptolocker and the evolution of ransomware While many attackers create botnets to steal data or use victim’s machines as launching points for further attacks, a specialized group of attackers have used strong-arm tactics to extort money from victims. In the past, most of these types of attacks, referred to as ransomware, have been bluffs, but Cryptolocker, which started spreading in late summer, uses asymmetric encryption to lock important files. The group behind Cryptolocker has likely infected between 200,000 and 250,000 computers in the first hundred days, according to researchers at Dell SecureWorks. Based on the number of payments made using Bitcoin, the company conservatively estimated that 0.4 percent of victims paid the attackers, but it is likely many times more than minimum take of $240,000, the company stated in an analysis. “What sets it apart is not just the size and the professional ability of the people behind it, but that–unlike most ransomware, which is a bluff–this one actually destroys your files, and if you don’t pay them, you lose the data,” says Keith Jarvis, senior security researcher with Dell SecureWorks. Companies should expect ransomware to adopt the asymmetric-key encryption strategy employed by the Cryptolocker gang. 2. New York Times “hack” and supplier insecurity The August attack on The New York Times and other media outlets by the Syrian Electronic Army highlighted the vulnerability posed by service providers and technology suppliers. Rather than directly breach the New York Times’ systems, the attackers instead fooled the company’s domain registrar to transfer the ownership of the nytimes.com and other media firms’ domains to the SEA. The attack demonstrated the importance of working with any suppliers that could be a “critical cog” in a company’s security strategy, says Carl Herberger, vice president of security solutions for Radware, a network security firm. “You need to have real-time, critical knowledge from your service providers to determine whether they are being attacked and whether you are the intended victim of that attack,” says Herberger. 3. Bit9 and attacks on security providers In February, security firm Bit9 revealed that its systems had been breached to gain access to a digital code-signing certificate. By using such a certificate, attackers can create malware that would be considered “trusted” by Bit9?s systems. The attack, along with the breach of security company RSA, underscore that the firms whose job is to protect other companies are not immune to attack themselves. In addition, companies need to have additional layers of security and not rely on any one security vendor, says Vikram Thakur, a researcher with Symantec’s security response group. “The onus resides with the security firm to prevent successful attacks from happening, but when they fail, a victim should have a plan to bolster their defense,” Thakur says. 4. DDoS attacks get bigger, more subtle A number of denial-of-service attacks got digital ink this year. In March, anti-spam group Spamhaus suffered a massive denial-of-service attack, after it unilaterally blocked a number of online providers connected–in some cases tenuously–to spam. The Izz ad-Din al-Qassam Cyberfighters continued their attacks on U.S. financial institutions, causing scattered outages during the year. As part of those attacks and other digital floods, attackers put a greater emphasis on using techniques designed to overwhelm applications. Such application-layer attacks doubled in frequency in the third quarter 2013, compared to the same quarter a year before, according to denial-of-service mitigation firm Prolexic. Reflection attacks, where attackers use incorrectly configured servers to amplify attacks, grew 265 percent in the same period, according to the firm. The attack against Spamhaus, which reportedly topped a collective 300 Gbps, used reflection attacks via open DNS resolvers to generate the massive flood of traffic. “This technique is still an available option for attackers,” says Radware’s Herberger. “Because there are 28 million vulnerable resolvers, and every resolver needs to be fixed, this problem is not going away any time soon.” 5. South Korea and destructive attacks Companies in both the Middle East and South Korea suffered destructive attacks designed to wipe data from computers. In 2012, Saudi Aramco and other companies in the Middle East were targeted with a malicious attack that erased data from machines, causing them to become unrecoverable. This year, South Korean firms were attacked in a similar manner in a multi-vector attack whose finale was the deletion of master boot records on infected computers. While such attacks have happened in the past, they seem to be more frequent, says Dell SecureWorks’ Williams. “The impact of these attacks have been pretty impressive–30,000 machines needed to be rebuilt in the Saudi Aramco case,” he says.

Lessons From 5 Advanced Attacks Of 2013

The Changing Trends of DDoS Attacks

Distributed denial-of-service (DDoS) attacks certainly aren’t new. I’ve been talking about them for years. However, they have been changing. The traditional style of attack, the flood-the-target type that crashes a website, is still going strong. But now we are seeing an increase in application-layer attacks that have the same goal: Systems go down, resources are unavailable and the victim is scrambling to fix everything. Recently, Vann Abernethy, senior product manager for NSFOCUS, talked to me about the changing DDoS landscape. Something he has noticed is how DDoS attacks are being used as smokescreens to cover up other criminal activity. He said: In fact, the FBI warned of one such attack type back in November of 2011, which relies upon the insertion of some form of malware. When the attacker is ready to activate the malware, a DDoS attack is launched to occupy defenders. In this case, the DDoS attack is really nothing more than a smokescreen used to confuse the defenses and allow the real attack to go unnoticed – at least initially. Considering that most malware goes undetected for long periods of time, even a small DDoS attack should be a huge red flag that something else may be going on. Abernethy adds that another trend he’s seeing is that the DDoS attack itself may be a bit more sinister. For example, a DDoS attack could be masking a simultaneous attack that is probing for vulnerabilities. He said: It’s like a recon team sent to look at an enemy’s position while they’re under some sort of long-range barrage. In general, basic probing will likely be caught if the victim has even modest security protections. But while under the duress of a DDoS attack, the very systems charged with either blocking or alerting suspicious activity might be under too much strain. Abernethy provides several solutions to protect against these emerging DDoS attack styles. One way is to have multiple teams set up to respond to DDoS attacks. One team would work on the DDoS attacks themselves; another team would be responsible for searching for other possible, hidden attacks. For the trend that involves probing, IT and security departments may want to deploy application security testing, and all applications used by the company should be subjected to the testing. DDoS attacks can be devastating to a company , interrupting vital customer interactions and ruining company reputations. The more we know about them, the better chance we have at protecting the company from any serious damage, if not preventing them altogether.

DDoS trojan ferrets SMB data

A new distributed-denial-of-service (DDoS) bot has been discovered targeting real estate companies and other small and medium-sized businesses. Arbor Networks researcher Dennis Schwarz found the malware after receiving a tip-off from a Twitter user. A relatively small number of unique samples and command and control servers were uncovered, making it difficult to judge just how dangerous the new threat could be. These samples are written in the Delphi programming language but most likely originate from Russia, said Schwarz, who added that the bot’s self-preservation tools include UPX packing, string obfuscation, anti-virtual machine, anti-bugging measures, self-modifying code and process hollowing. Command and control is done over HTTP. The analyst firm has a ‘fairly complete picture’ of what the bot represents, but admitted concerns on how Trojan.Ferret is being distributed. “Trojan.Ferret is a new Russian DDoS bot. It stood out to me due to the silly ferret theme and that we have a fairly complete picture of it,” said Schwarz, adding that the company had tracked a sample of bot, the C&C panel view and live C&C traffic. “It is a traditional DDoS bot focusing on the ‘core’ set of DDoS attacks, such as HTTP, UDP and TCP. It lacks the common application layer attacks such as Slowloris, Apache Killer, and RUDY. “A major missing component that we’re unsure of is how this particular Trojan is being distributed–whether by exploit kit, malware-laced spam, or via one of the many ‘dropper/downloader’ networks.” Schwarz said that the Trojan is targeting the UK, the US, Germany, Russia and the Netherlands, as well as Kazakhstan, and said that attacks have hit property companies, an electronics shop, a wedding dress shop and even a politician in Panama. Malwarebytes malware intelligence analyst Adam Kujawa said the information security industry is still coming to grips with the threat posed by the new DDoS bot. “It is likely of Russian origin, uses an array of specialised malware tricks to hide it from detection and of course is used as a DDOS bot,” said Kujawa. “Ferret will infect as many systems as it can to recruit them into the Botnet and then use each of those systems to attack a single server at the same time,” he added, commenting, “A single system cannot perform a successful DDOS attack but a botnet of thousands can.” Source: http://www.scmagazine.com.au/News/368168,ddos-trojan-ferrets-smb-data.aspx

7 Security Trends to Expect in 2014

Computer systems, in many peoples’ eyes, are there to be hacked — and that means fraudsters are always working on new ways to exploit vulnerabilities. So what does 2014 have in store? Here are seven security predictions for the New Year. DDoS Attacks Get Sneaky DDoS attackers will go from simple volumetric attacks to ones which take advantage of a site’s specific performance characteristics. That’s the prediction of security researchers at Neohapsis, a security and risk management consulting company. DDoS attacks that intelligently target bottlenecks in performance, such as pages with a high server load (like database writes) or specific network bottlenecks (like login and session management), can magnify the impact over attacks which are simply volume-based and request the homepage of a site. So it’s likely that we will begin to see the spread of tools which profile specific targets. The result? DDoS attacks that have more impact, and involve less network traffic, than the ones enterprises have become accustomed to mitigating against. Insider Threats Remain Major Security Problem According to a CyberSecurity Watch survey insiders were found to be the cause in 21 percent of security breaches, and a further 21 percent may have been due to the actions of insiders. More than half of respondents to another recent survey said it’s more difficult today to detect and prevent insider attacks than it was in 2011, and 53 percent were increasing their security budgets in response to insider threats. While a significant number of breaches are caused by malicious or disgruntled employees – or former employees – many are caused by well-meaning employees who are simply trying to do their job. BYOD programs and file sharing and collaboration services like Dropbox mean that it will be harder than ever to keep corporate data under corporate control in the face of these well-meaning but irresponsible employees. Defending against insider threats requires a multi-layered use of technological controls, including system-wide use of data encryption and establishment of policies stressing prevention of data loss. Security Worries Drive Cloud Consolidation Organizations will look to buy more solutions from a single vendor and demand greater integration between solutions to automate security, according to Eric Chiu, president of HyTrust, a cloud security company. The fact that securing cloud environments is very different from securing traditional physical environments will drive greater consolidation in the market, he says. Legacy Systems Cause More Security Headaches The spate of IT failures in banks and other high profile companies highlights a simple fact: Many of them are running legacy systems which are so old and out of date that they are becoming almost impossible to maintain. That’s because there are few people with the skills and expert knowledge that would be needed to run them securely – even if they were updated to eliminate know vulnerabilities, which they frequently are not. They often aren’t updated because no-one knows what impact that would have. It’s inevitable that we’ll see hackers going after such systems, exploiting vulnerabilities that can’t easily be fixed. Encryption Will Be Revisited In the wake of revelations about the NSA, many companies are realizing that encryption many be the only thing that is protecting their data, and it may not be as strong as they imagined. What’s more, if hackers are led to believe there is a weakness in a particular system – either accidental or intentional – they will pound on it until they find it. As a result, many companies will look to improve the way they use encryption. Look for particular attention to be paid to cryptographic block modes like CBC and OFB, and authenticated modes like EAX, CCM and GCM, advise the experts at Neohapsis. In addition to the encryption methods themselves, look for insights and innovations around key management and forward security. ‘Stuxnets’ Become More Common State-sponsored malware like Stuxnet – which is widely attributed to the United States, Israel or both – has proved to be far more sophisticated and effective than anything that a couple of hackers can develop. Expect more of this type of malware from the likes of China, Russia, Iran, India, Brazil and Pakistan. It’s probably already out there, even if it hasn’t yet been detected. 2014 could be the year that its prevalence becomes apparent. Bitcoin Drives New Malware The Bitcoin virtual currency is growing in popularity with legitimate businesses, and that’s likely to continue. That’s because Bitcoin payments offer significant attractions: They are quick and cheap, and there is no possibility of a chargeback. But Bitcoin wallets make attractive targets for criminals, because stolen coins can be cashed out instantly, without a middleman or launderer taking a cut. And many Bitcoin users are relatively unsophisticated, protecting their wallets with very little security. So expect Trojans and other malware that specifically look for and target Bitcoin stashes, as well as ransomware that demands Bitcoins in return for decrypting data.

7 Security Trends to Expect in 2014

New DDoS malware targets Linux and Windows systems

Attackers are compromising Linux and Windows systems to install a new malware program designed for launching distributed denial-of-service (DDoS) attacks, according to researchers from the Polish Computer Emergency Response Team (CERT Polska). Attackers are compromising Linux and Windows systems to install a new malware program designed for launching distributed denial-of-service (DDoS) attacks, according to researchers from the Polish Computer Emergency Response Team (CERT Polska). The malware was found by the Polish CERT at the beginning of December and the Linux version is being deployed following successful dictionary-based password guessing attacks against the SSH (Secure Shell) service. This means only systems that allow remote SSH access from the Internet and have accounts with weak passwords are at risk of being compromised by attackers distributing this malware. “We were able to obtain a 32-bit, statically linked, ELF file,” the Polish CERT researchers said Monday in a blog post. The executable runs in daemon mode and connects to a command-and-control (C&C) server using a hard-coded IP (Internet Protocol) address and port, they said. When first run, the malware sends operating system information — the output of the uname command — back to the C&C server and waits for instructions. “From the analysis we were able to determine that there are four types of attack possible, each of them a DDoS attack on the defined target,” the researchers said. “One of the possibilities is the DNS Amplification attack, in which a request, containing 256 random or previously defined queries, is sent to a DNS server. There are also other, unimplemented functions, which probably are meant to utilize the HTTP protocol in order to perform a DDoS attack.” While executing an attack, the malware provides information back to the C&C server about the running task, the CPU speed, system load and network connection speed. A variant of the DDoS malware also exists for Windows systems where it is installed as “C:Program FilesDbProtectSupportsvchost.exe” and is set up to run as a service on system start-up. Unlike the Linux version, the Windows variant connects to the C&C server using a domain name, not an IP address, and communicates on a different port, according to the Polish CERT analysis. However, the same C&C server was used by both the Linux and Windows variants, leading the Polish CERT researchers to conclude that they were created by the same group. Since this malware was designed almost exclusively for DDoS attacks, the attackers behind it are likely interested in compromising computers with significant network bandwidth at their disposal, like servers. “This also probably is the reason why there are two versions of the bot — Linux operating systems are a popular choice for server machines,” the researchers said. However, this is not the only malware program designed for Linux that was identified recently. A security researcher from the George Washington University, Andre DiMino, recently found and analyzed a malicious bot written in Perl after allowing attackers to compromise one of his honeypot Linux systems. The attackers were trying to exploit an old PHP vulnerability, so DiMino intentionally configured his system to be vulnerable so he could track their intentions. The vulnerability is known as CVE-2012-1823 and was patched in PHP 5.4.3 and PHP 5.3.13 in May 2012, suggesting the attack targeted neglected servers whose PHP installations haven’t been updated in a long time. After allowing his honeypot system to be compromised, DiMino saw attackers deploy malware written in Perl that connected to an Internet Relay Chat (IRC) server used by attackers for command and control. The bot then downloaded local privilege escalation exploits and a script used to perform Bitcoin and Primecoin mining — an operation that uses computing power to generate virtual currency. “Most servers that are injected with these various scripts are then used for a variety of tasks, including DDoS, vulnerability scanning, and exploiting,” DiMino said Tuesday in a blog post that provides a detailed analysis of the attack. “The mining of virtual currency is now often seen running in the background during the attacker’s ‘downtime’.” DiMino’s report comes after researchers from security vendor Symantec warned in November that the same PHP vulnerability was being exploited by a new Linux worm. The Symantec researchers found versions of the worm not only for x86 Linux PCs, but also for Linux systems with the ARM, PPC, MIPS and MIPSEL architectures. This led them to conclude that the attackers behind the worm were also targeting home routers, IP cameras, set-top boxes and other embedded systems with Linux-based firmware.

DDoS attacks lead to 18 percent of data center outages

Maintaining top-of-the-line server performance is a delicate balancing act between power consumption, user accessibility and a variety of other factors both physical and abstract that can affect how well employees do their jobs or how quickly and effectively IT-related tasks are accomplished. Yet in many cases, even the most stringent attempts to keep the data center operating without issue can run afoul due to external forces. In the past, distributed-denial-of-service (DDoS) attacks were a small fraction of the reasons that businesses experienced outages in their IT infrastructure. However, recent findings from the Ponemon Institute reveal that they now account for 18 percent of these problems. This is up from only 2 percent in 2010, when Ponemon last studied the phenomenon. Data centers get caught in the cross-fire Often enough, these attacks are not even targeting data centers, 451 Research analyst Eric Hanselman told Network Computing. Rather, hackers are attempting to shut down the applications hosted in the IT infrastructure, and the servers become collateral damage in the process. Furthermore, due to the heightened sophistication of DDoS attacks, which are now both faster and more effective due to the amount of traffic that can be generated, these assaults are even harder to stop or recover from than ever. “It appears that these attacks are much more frequent and more difficult to contain than other root causes of data center outages,” Larry Ponemon, founder of the privacy and security think tank that bears his name, said in an email interview with Network Computing. Preventative measures begin with server monitoring Due to the problems associated with these attacks, decision-makers should try and stop them as early as possible. Noticing suspicious activity before it causes an outage can help immensely, but that requires businesses to implement server monitoring tools that can notice suspicious activity such as an uptick in traffic. “The most surprising factor was the lack of readiness or preparedness of companies,” Ponemon told Network Computing. “In general, we found several companies completely unprepared to deal with this type of outage event.” The high cost of a DDoS-based outage Those companies that fail to prevent or ready themselves for a DDoS-based outage may find themselves paying $822,000 on average to deal with the problem, second only to the average cost of outages caused by equipment failure ($959,000), according to Network Computing. This is more than double the expense of dealing with problems originating with human error, which typically only amount to $380,000. These costs relate to lost work time, reduced revenue and the repairs themselves, though overall business disruption amounts to 80 percent of the expenses. While an outage may not be quite as expensive to a smaller business, one could cause relatively similar amounts of damage, and all companies should be ready to quickly get back on their feet after these types of incidents. “The cost of unplanned downtime – whether it is the entire data center or one rack of servers – can be a huge unplanned cost for most organizations,” Ponemon told Network Computing. While Ponemon noted that businesses should expect a data center outage at some point, companies should still strive to minimize the possibility of a breach or attack. Putting in the proper safeguards and having a robust disaster recovery plan in place can reduce the amount of time that servers spend out of service. By implementing the right tools to notice and stop suspicious activity that may be the result of a DDoS attack, decision-makers may also potentially prevent about one-fifth of possible outage causes.

The Year DDoS Got Real for CUs

Before 2013, Distributed Denial of Service attacks seemed to many credit union executives as something the other guys worried about. The prevailing attitude was: We’re not on anyone’s radar. We aren’t on anyone’s enemies list. Why worry? Then came January 2013 when the $1.6 billion University Federal Credit Union in Austin, Texas, and Patelco, the $4 billion Pleasanton, Calif. credit union, both acknowledged they had been knocked offline for some hours. Many big banks were taken down at the same time, in attacks claimed by al Qassam Cyberfighters, an organization that many allege is sponsored by the Iranian government. A month later, in February, both institutions were taken down another time, again in attacks claimed by al Qassam. Many banks also fell victim a second time. There were also dud DDoS attacks, such as a much-ballyhooed May 7 attack – which saw institutions fearfully running for cover from an attack said to be planned by OpUsa, a hacktivist group affiliated with Anonymous – but it amounted to nothing. As the year progressed, there were more reports of DDoS used as a diversionary tactic by criminals who sought to distract financial institution security staff with website attacks as they busied themselves perpetrating high-value wire thefts. There have been no such cases publicly linked to credit unions, but there are multiple cases linked to banks. How many credit unions have been taken down by DDoS? That number is unknown. Patelco and University were named in Internet postings by al Qassam, thus their attacks became public knowledge. The NCUA, for its part, requires credit unions that have been “significantly affected by DDoS” to notify the NCUA or their state regulators. When asked in October for the number of credit unions that had filed reports, the agency shared data showing two outages. But the regulator did not indicate that it believed that tally to be complete. CUNA Mutual, at the same time, indicated it had no count whatsoever of DDoS outages. No one really knows how many credit unions were attacked by DDoS in the year but one fact did seem to emerge. “DDoS has become a perennial, it is here to stay in the threats universe,” said Charles Burckmyer, president of Sage Data Security, a firm that claims several hundred financial institutions as clients. Just what is DDoS? The question is good, because the answer is tough to give. That’s because the format of DDoS shifted dramatically in 2013, said Rodney Joffe, senior technologist at Neustar, an Internet analytics company that also offers DDoS mitigation services. Early in the year, Joffe recalled, DDoS sought to wipe out victim websites by targeting them with huge volumes of traffic – generally assembled using resources stolen from zombie computer botnets where the machine owners have no clue their devices are digital slaves to criminals. So those targets – such as Patelco and UFCU – went down because they were overwhelmed. But DDoS attacks and mitigation strategies continually evolve, said Joffe. When one side jigs, the other responds. That showed up as many financial institutions signed up with third-party mitigation companies to provide emergency “pipe” – Internet bandwidth – to be able to deflect volume-based attacks. So the attackers switched to hitting victims with an avalanche of requests for services that had the effect of using the target computers to in effect tire themselves, noted Stephen Gates, chief security evangelist of Corero Network Security. A classic, for instance, is hitting a financial institution website with many requests for a password reset, probably for non-existent members, but the institution’s computer still is forced to go through so many motions it may become unavailable to genuine users. Pierluigi Stella, chief technology officer at security company Network Box USA, elaborated: “The (DDoS criminal’s) query is usually less than 100 bytes; the reply can be tens of thousands; so the hacker gets an amplification factor of 100. For each packet of 100 bytes the hacker sends out, you get hit by 10,000 bytes.” Multiply that by maybe several hundred queries per second and it is easy to see why this attack has proven so successful in 2013, suggested Stella. The cure, said experts, is to deploy tools that in effect scrub all data as it comes into the system. Bad data is sidelined, authentic data is passed through, and while that is easier to prescribe than it is to implement in practice, experts agreed that DDoS mitigation companies took large strides in 2013 towards building tools that in fact scrubbed incoming data with high success rates. The bad news: Nobody thinks today’s DDoS format will be tomorrow’s, and no one knows what criminals will unleash in the months ahead. Maybe the jackpot question is, how well protected are credit unions when it comes to fending off DDoS, especially as it morphs into different formats? Have they invested in state-of-the-art protections? Not very many have made those investments, said multiple experts contacted by Credit Union Times. Few credit unions will discuss their DDoS defenses on the record but off the record some have indicated that their defenses are thin. Many hope that their vendors – for Internet banking or their Internet service provider – have adequate protections in place to keep the credit union itself also protected. DDoS will remain part of the threats landscape, said multiple experts, mainly because it is effective, it is inexpensive, and it is increasingly easy to deploy. As long as it gets results, criminals will continue to use it, said Joffe. Nonetheless, he flatly predicted that we will not see more of the al Qassam-style, high-profile attacks that won headlines early in 2013. “Those attacks were politically motivated but they accomplished nothing,” said Joffe. Other experts agreed, pointing to changes in Iranian politics and a recent thawing in relationships with the United States. The upshot is that the al Qassam attacks may in fact be history, meaning there may not be more days when several dozen financial institutions are taken offline in a brazen show of Internet power. “But we will see more DDoS because it works,” said Joffe, and he specifically predicted more use of it as a diversion because if a security staff can be distracted for a half-day, that may be ample time for a wire transfer to move money out of the United States and through several hops into a destination country where funds are unlikely to be returned. Gartner analyst Avivah Litan – one of the experts who first reported the use of DDoS as a diversion – noted in an interview that good policy would be to “slow” wire transfers at times when the institution found itself under a DDoS attack. Her opinion is that simply slowing down transaction speed might sharply reduce losses. At least until the criminals figure out a new strategy – and that is a big takeaway from the 2013 DDoS saga. “This is an arms race that is no different from any other arm’s race,” said Joffe. “As we add defenses, the criminals alter their attacks and so it goes on.” The good guys win, said Joffe, by making it expensive for the criminals, such as disrupting their botnet zombie networks. “If we can make it more expensive for them than the rewards they get from their DDoS, we win,” said Joffe. “This will be survival of the fittest,” he warned.

Introducing the DDDoSA: Disguised DDoS Attack

The Distributed Denial of Service (DDoS) attack is becoming the crowbar of the online criminal. In the past we have got rather used to DDoS attacks being one of the favoured approaches of hacktivists, with perhaps the Low Orbit Ion Cannon (LOIC) and later the High Orbit Ion Cannon (HOIC) as used by Anonymous to take down sites being the best known examples. However, recent evidence suggests that taking down a site is increasingly no longer the be all and end all of a DDoS attack, instead it’s just a means to a much more profitable end. A couple of weeks ago I reported how a Bitcoin bank robbery took place under the smokescreen of a DDoS attack. I’ve now learned that a DDoS attack on another Bitcoin-related site, the Bitcointalk.org online forum, could also have been implemented as a smokescreen tactic. Information Week reports the site was actually targeted for a password-stealing exercise with some 176,584 users login credentials at risk. Indeed, as TK Keanini (CTO at Lancope) points out there is an established marketplace out there selling the DDoS capability to anyone with the cash, and relatively little of it is needed to attack a smaller company, so the bad guys don’t even need a DDoS strike capability as a core competency any more. “It is almost always the case these days that DDoS attacks leverage blended methods, where the volumetric technique is included, but not the primary objective” Keanini says, adding “this is a sign of what is to come in 2014 as more adversaries just put together a multi faceted compostable attack and instead of having to have all this expertise in-house, they will be able to outsource via these marketplaces that sell these capabilities.” Jag Bains, CTO at DDoS mitigation experts DOSarrest says that his company has been seeing DDoS attacks sending huge amounts of traffic to a website to overwhelm key points in its infrastructure to send the security team scrambling to fight it off as something of a trend. “This serves as a distraction for the security personnel and aims to weaken the underlying infrastructure” Bains explains “once the security operations are no longer cohesive, criminals can use other methods to target intrusion prevention systems to get in and steal information”. All of which just goes to reinforce that maintaining the focus of core operations during a DDoS attack is an ever increasing problem for IT operations. “As DDoS continues to be used as part of a 1-2 punch in cybercrime and data theft attempts” Bains concludes “IT professionals have become stressed in keeping up with the ever increasing size and sophistication of DDoS attacks”. All of which can influence an organisation to resort to what you might call non-standard, or panicked, practices to deal with the ongoing attack. Things such as disabling their IDS platform for example. Things that further compromise the overall security of the network and enable the attackers to pull off the primary attack with ease.

RBS hit by DDoS attack that takes down online services again

UK BANKING GROUP Royal Bank of Scotland (RBS) has been hit by a distributed denial of service (DDoS) attack that took down its online services for the second time this week. Earlier this week, RBS irked customers when an IT systems failure shut down its websites and caused its customers’ bank cards to fail. On Friday it admitted that it has been struck by a DDoS attack affecting its online services once again. RBS took to Twitter to reveal news of the DDoS attack. It said, “Due to a surge in internet traffic directed at the Natwest website, customers experienced difficulties accessing some of our sites today. “This deliberate surge of traffic is known as a distributed denial of service (DDoS) attack. We have taken action to restore affected sites. “At no time was there any risk to customers. We apologise for the inconvenience caused.” RBS has yet to comment further, so it’s still unclear which websites were downed in the attack, although the tweet suggested that the RBS, Natwest and Ulster Bank websites were all affected. It is also still unclear who was responsible for the DDoS attack. However, it seems that the problems have not reached as far as those experienced by RBS customers earlier this week, when an IT systems failure struck the entire banking group. Speaking about the system failure on Monday evening, RBS CEO Ross McEwan said on Tuesday, “Last night’s systems failure was unacceptable. Yesterday was a busy shopping day and far too many of our customers were let down, unable to make purchases and withdraw cash. “For decades, RBS failed to invest properly in its systems. We need to put our customers’ needs at the centre of all we do. It will take time, but we are investing heavily in building IT systems our customers can rely on. “I’m sorry for the inconvenience we caused our customers. We know we have to do better. I will be outlining plans in the New Year for making RBS the bank that our customers and the UK need it to be. This will include an outline of where we intend to invest for the future.” Source: http://www.theinquirer.net/inquirer/news/2317692/rbs-hit-by-ddos-attack-that-takes-down-online-services-again

RBS hit by DDoS attack that takes down online services again

Bitcoin Password Grab Disguised As DDoS Attack

Attacks against bitcoin users continue, as online forum Bitcointalk.org warns users their passwords might have been stolen in distributed denial of service hack. Aficionados of the cryptographic currency known as Bitcoin might have gotten more than they bargained for recently, after a distributed denial-of-service (DDoS) attack appeared to be used as a smokescreen for launching a password-stealing attack against users of Bitcointalk.org. Michael Marquardt (a.k.a. “Theymos”), one of the administrators of the popular bitcoin discussion forum, Sunday warned its 176,584 members of the attack. He said the attack had been traced to a flaw in the systems of domain registration firm AnonymousSpeech, which specializes in anonymous email, as well as running hosting servers outside the United States and the European Union. Attackers hacked AnonymousSpeech to change the bitcoin discussion forum’s DNS settings to an attacker-controlled server. According to Marquardt, the DNS redirection attack was spotted Sunday by forum manager Malmi Martti (a.k.a. Sirius), who immediately moved the domain to a different registrar. “However, such changes take about 24 hours to propagate,” he warned, meaning that users remained at risk unless they logged on to the forum using its IP address, rather than trusting domain name servers to resolve to the non-malicious site. What was the risk to forum users? “Because the HTTPS protocol is pretty terrible, this alone could have allowed the attacker to intercept and modify encrypted forum transmissions, allowing them to see passwords sent during login, authentication cookies, [personal messages], etc.,” Marquardt said. “Your password only could have been intercepted if you actually entered it while the forum was affected. I invalidated all security codes, so you’re not at risk of having your account stolen if you logged in using the ‘remember me’ feature without actually entering your password.” In other words, anyone who logged into the forum between Sunday and Monday, and who entered a password, should assume that it was compromised by attackers. What were the bitcoin forum attackers gunning for? The most likely explanation would be participants’ usernames and passwords, which — if reused on other sites — might have allowed attackers to drain people’s online bitcoin wallets. Likewise, attackers might have been interested in gathering email addresses of people who are interested in bitcoins to target them — via phishing attacks — with malware designed to find and steal bitcoins from their PCs. The DNS hack and DDoS attack against Bitcointalk are just the latest exploits in a long string of attacks targeting bitcoin e-wallet services and payment systems. Last month, Denmark-based bitcoin payment processor Bitcoin Internet Payment System suffered a DDoS attack that allowed the attackers to hide their real target: online wallets storing 1,295 bitcoins, which they successfully stole. At the time, their haul was valued at nearly $1 million. As that haul suggests, the rise in bitcoin-related attacks can be attributed to the bitcoin bubble, which has seen the value of the cryptographic currency rise from a low of $1 per bitcoin in 2011, to $1,200 per bitcoin as of Wednesday. The rise in bitcoin’s value has lead to a number of malicious attacks, as well as a rise in efforts of a different nature. Last week, for example, Malwarebytes researcher Adam Kujawa warned in a blog post that a number of free toolbars and search agents have begun including bitcoin-mining software, which can consume massive amounts of system resources, slowing PCs to a crawl. Bitcoin mining isn’t inherently suspect. In fact, it’s crucial to the success of bitcoins, because it’s what records the chain of bitcoin transactions. Furthermore, the bitcoin system is set up to reward — with bitcoins — anyone who successfully solves related cryptographic puzzles that help maintain the public bitcoin ledger known as the “block chain.” But some people have begun turning PCs into nodes in their personal bitcoin-mining empire, such as online gaming company E-Sports, which was recently hit with a related $325,000 fine by the New Jersey state attorney general’s office. In the case of toolbars and search agents with built-in mining software, however, users who agree to the accompanying end-user license agreement (EULA) might be authorizing a third party to turn their PC into a bitcoin-mining platform. “So take note if your system is running especially slow or if a process is taking up massive amounts of your processing power; it might be malware or even a [potentially unwanted program] running a miner on your system,” said Kujawa at Malwarebytes. “Looks like the bad guys are adapting all of their various technical attacks and business models to the bitcoin world,” CounterHack co-founder and SANS Institute hacking instructor Ed Skoudis said in a recent SANS email newsletter, responding to the Malwarebytes report. “Given the stakes for rapid money-making here, we’ll surely see even more creative bitcoin-related attacks in the near future.” Source: http://www.informationweek.com/security/attacks-and-breaches/bitcoin-password-grab-disguised-as-ddos-attack—-/d/d-id/1112919
