DDoS attack downs Twitch on news of Amazon acquisition

Just hours after Amazon announced a $970m deal to acquire Twitch, the live video platform for gamers was taken offline temporarily by a distributed denial of service (DDoS) attack. Twitch is the latest in a string of online gaming platforms to be hit by DDoS attacks that have been linked to several groups, including Lizzard Squad, jihadist group Islamic State, and Anonymous. At the weekend, Sony’s PlayStation Network was knocked offline and several others experienced disruptions, including Microsoft’s Xbox Live and Blizzard’s Battle.net. DDoS attacks are commonly used by competitors or activists to take services offline using a variety of techniques that make services impossible to reach. The reason for the DDoS attack on Twitch is unknown, but industry pundits have speculated that it may be linked to concerns about the acquisition by Amazon. Commenting on the weekend disruptions, Dave Larson, CTO at Corero Network Security, said the drivers for launching DDoS attacks are far ranging and difficult to pinpoint in many cases. “Anyone can become a victim at any time and, as the attacks continue to become stronger, longer and more sophisticated, businesses that rely on their online web applications as a revenue source cannot become complacent,” he said. Larson said the latest DDoS attacks underscore the importance of including a DDoS first line of defence as a component of network security architecture. Lancope chief technology officer TK Keanini said that while DDoS was once a resource held by a few of the elite groups on the net, this method of attack is now available to anyone as it is offered as a service. “If you know where to look, and you have some crypto currency in hand, just point and shoot,” he said. According to Keanini, any business connected to the internet is likely to be targeted by a DDoS attack at some point. “But game networks have to work harder than most to remain secure as they are incredibly attractive targets. “Not only are they high profile, with any disruption making the news, but given all the in-game commerce, credit card and personal information is kept up to date and can be monetised by these cyber criminals,” he said.

PlayStation network back online after DDoS attack

Sony’s PlayStation and Entertainment networks are back online after they were forced offline by a distributed denial-of-service (DDoS) attack, the company said late Sunday. “People can now enjoy the services on their PlayStation devices,” Sony spokesman Sid Shuman wrote in a blog post “We have seen no evidence of any intrusion to the network and no evidence of any unauthorized access to users personal information,” he said, also offering apologies for any inconvenience caused. Sony was hit by a large scale DDoS attack which struck upstream traffic routes over which Sony has no control, affecting players’ ability to log in, Sony Online Entertainment President John Smedley wrote on Twitter on Sunday. DDoS attacks attempt to crash a network by sending large amounts of data to a service provider. A group calling itself the “Lizard Squad” claimed on Twitter to be behind the attack. It said that it had “planted the ISIS flag on @Sony’s servers,” referring to the militant group that occupies parts of Syria and Iraq. Earlier on Sunday, the group tweeted directly to American Airlines writing that it had “received reports” that a flight carrying Smedley “has explosives on board.” This appeared to be a way to aggravate Sony further. Smedley had tweeted earlier that his flight had been diverted for reasons that had to do with “something about security and our cargo.” The Boeing 757, with 179 passengers and six crew which left from Dallas-Fort Worth for San Diego was diverted to Phoenix due to a “a security-related issue” and landed safely, according to American Airlines.

Eve Online Servers Knocked Offline Due to DDoS Attacks

Eve Online, the space-based videogame with over half a million active players, has been forced offline for more than 12 hours due to a series of cyber attacks against a cluster of its servers located in London. According to the Eve Online Status Twitter account, the first signs of trouble were seen at around 8pm on Thursday, 21 August, and by 11pm the Icelandic-based CCP Games which develops the game had confirmed the problem was due to a series of distributed denial of service (DDoS) attacks. DDoS attacks are a common tool used by criminals to flood servers with traffic in order to knock them offline and unavailable to anyone trying to access them. Some had apparently linked the offline status of the game to the recent activity of the Bardarbunga volcano in Iceland which is on the verge of erupting, however CCP Games explicitly ruled this out.   The problem is affecting the Tranquility server cluster, which all Eve Online players connect to in order to play the game. This cluster of servers is based in London. Even the Eve Online wiki is inaccessible as it too is seemingly hosted on the Tranquility server. An update from CCP Games on Twitter at 8am on Friday, 22 August, simply saying: “Tranquility is currently under heavy load again” and pointing player to a forum thread. However this thread also appears to be offline at the time of publication. DDoS attacks are often used by unscrupulous companies in order to knock rivals offline for a sustained period of time, with many cyber-criminals renting out DDoS services for as little as £5-an-hour. Eve Online is a massively multiplayer online game set in the fictional world of New Eden where players pilot customisable spaceships through a galaxy of over 7,500 star systems. The game is also unique in that its developers create the structure of New Eden but then handed over control of what happens in the game to the players. The rest is a virtual world where corporations and alliances hold huge power and where huge battles can cost the equivalent of over $300,000 in real world money.

Chinese Linux Trojan makes the jump to Windows – DDoS attacks largely aimed within China

A CHINESE TROJAN , one of the few to be written for the Linux operating system, has seemingly made the jump to Windows. First reported in May by Russian anti-malware software house Dr Web, the original malware known as “Linux.Dnsamp” is a Distributed Denial of Service (DDoS) Trojan, which, according to the company blog, transfers between Linux machines, altering the startup scripts, collecting and sending machine configuration data to the hackers’ server and then running silently waiting for orders. Now it appears that the same hackers have ported the Trojan to run in Windows as “Trojan.Dnsamp.1? The Windows version gains entry to the system under the guise of a Windows Service Test called “My Test 1?. It is then saved in the system folder of the infected machine under the name “vmware-vmx.exe”. When triggered, just like its Linux counterpart, the Trojan sends system information back to the hackers’ central server and then awaits the signal to start a DDoS attack or start downloading other malicious programs. Fortunately, the vast majority of the attacks using this method were aimed at other Chinese websites, which were attacked 28,093 times, but Dr Web warns that US websites came second with nine percent of attacks. Although the threat of malware is an everyday hazard to most computer users, to find an attack on Linux is much rarer, and to find any kind of malware that has been ported from one operating system to another is almost unheard of. In June, RSS reader service Feedly, note app Evernote and streaming music service Deezer all suffered DDoS attacks. Google is working on Project Shield, an initative designed to help smaller web servers fight off DDoS attacks.

DDoS extortion attacks on the rise

While digital ransom attacks come in various types and forms, Distributed Denial of Service (DDoS) attacks are top of the list of methods used by attackers to force money from targeted companies. So says Bryan Hamman, territory manager of Arbor Networks, who points out that in recent weeks, well-known names such as Evernote and Feedly have fallen victim to extortion attacks, but these companies are just the tip of the iceberg when it comes to this very lucrative criminal activity. InfoSecurity Magazine reports that this year the number of network time protocol amplification attacks increased 371.43%. The average peak DDoS attack volume increased a staggering 807.48%. The news aggregator Feedly said it had come under a DDoS attack from cyber criminals, which was preventing users from accessing its service. “Criminals are attacking Feedly with a distributed denial of service attack. The attacker is trying to extort money from us to make it stop. We refused to give in and are working with our network providers to mitigate the attack as best as we can,” said Feedly in a blog post. “‘Pay up or we’ll take your Web site down’, so goes the adage that usually accompanies ransom-based cyber-attacks,” says Hamman. According to Arbor’s ninth annual Worldwide Infrastructure Security Report, DDoS extortion attacks account for 15% of all DDoS attacks. While it may seem like a relatively small percentage, one must consider that as many as 10 000 DDoS attacks occur world-wide every day and the potential cost in damages and reputation can have a significant impact on a targeted organisation, Hamman points out. He explains that DDoS extortion attacks are generally volumetric, high bandwidth attacks launched with the aim of crashing a company’s Web site or server by bombarding it with packets, which originate from a large number of geographically distributed bots. The size of volumetric DDoS attacks continues to increase year on year, and they remain a major threat to enterprises and Internet service providers alike, he adds. “Traditionally, DDoS extortion attacks were used against online gambling sites, around major sporting events. Criminal gangs would initiate attacks that would bring the Web site down just before the event was to start, thus forcing the companies to choose between suffering a major loss in monetary and reputational terms or paying up. Increasingly, however, DDoS attacks are being used to extort money from all sorts of businesses and the reality is that no company should feel safe,” he says. So what is the right response when it comes to extortion demands? Hamman asks. “The answer is simple and always the same – not to give in. Organisations should under no circumstances agree to pay the ransom – it can set a dangerous precedent and encourage more attacks in the future; while it might make the pain go away in the short term, the long-term results are generally not worth it. “Declining to pay comes, of course, with severe consequences – as we saw from recent attacks on Feedly, who suffered from three separate waves of DDoS attacks. However, the company has now recovered from the attack and is operating as normal. Furthermore, it has been praised for its brave decision by the security community and even its own customers,” says Hamman. According to Hamman, many companies still rely on reactive measures such as router filters and firewalls, which are inefficient and not sophisticated enough to protect against organised cyber crime. Instead, he says, organisations need to invest in preventive, multi-layered mitigation, which includes on-premise and cloud protection, as well as allowing for co-operation with their ISP or hosting company. In addition, putting a mitigation strategy in place, should the worst happen, is of crucial importance – especially as only 17% of organisations globally feel they are fully prepared for a security incident. “By building defences, implementing plans ahead of time and refusing to give in, businesses needn’t feel threatened anymore – attackers wanting to make easy money will have to look elsewhere.” Source: http://www.itweb.co.za/index.php?option=com_content&view=article&id=136989:DDoS-extortion-attacks-on-the-rise&catid=265

Attacker could use default defibrillator password to launch DDoS attack

Jay Radcliffe freaked out the medical community in 2011 when he revealed how insulin pumps could be hacked to deliver a fatal dose of insulin (pdf). Yet at a medical device security and privacy roundtable discussion at Black Hat, Radcliffe said “it would be far easier and more likely for an attacker to sneak up behind him and deliver a fatal blow to his head with a baseball bat,” than hack his insulin pump to kill him. He did discuss hacking implantable medical devices. There are no known cases of hacking a pacemaker in anything other than fiction, but if an attacker remotely hacked a pacemaker, no one is going to dig into the death. It would be called a heart attack and that would be the end of it because “there’s no process in place right now that checks these implanted medical devices for failure or malicious activity.” Rapid7 point out, “Security often just isn’t on the radar at all for the manufacturers, the pharmaceutical regulators, or even the medical professionals that work with them.” The term “medical device” could mean a broad range of things from pacemakers to “MRI machines and echo-cardiograms and computers in the hospital running Windows XP. Mobile apps and health-related consumer-focused applications could also be considered under this broad umbrella.” John Pescatore, who previously worked at the NSA and at the U.S. Secret Service before joining SANS, released a whitepaper based on a survey about Internet of Things security. Medical machinery and personal implanted medical devices are considered to be part of the IoT. After all, people can use SHODAN to find fetal heart monitors if they are so inclined. Pescatore wrote: Internet-connected computing capabilities related to smart building and industrial control systems and medical devices were the most commonly cited concerns after consumer devices. While these type of devices don’t receive much hype with respect to the IoT in the press, the use of embedded computing in those devices (versus layered operating systems and applications in PCs and servers that IT is accustomed to managing and securing) will cause major breakage in existing IT management and IT security visibility, vulnerability assessment, configuration management and intrusion prevention processes and controls. SANS also looked at cyberthreat intelligence provided by Norse and then published a whitepaper about “Widespread Compromises Detected, Compliance Nightmare on Horizon.” Norse analyzed over 100 terabytes of daily traffic and determined there were 49,917 unique malicious events, 723 unique malicious source IP addresses and 375 U.S.-based compromised health care-related organizations. “There are many reasons why these findings are cause for alarm,” wrote Barbara Filkins. One example was: “The sheer volume of IP addresses detected in this targeted sample can be extrapolated to assume that there are, in fact, millions of compromised health care organizations, applications, devices and systems sending malicious packets from around the globe.” Those aren’t the only threats. If a person was in cardiac arrest, a defibrillator could be used to save that person’s life. But what if someone who was not authorized to use or to tweak the defibrillator settings, did so? That may be unlikely, but not impossible. Default usernames and passwords for medical devices are problematic and are “often overlooked endpoints;” they “can be easily procured by an Internet search on ‘type of device’ plus ‘default password’.” Yesterday, the National Vulnerability Database published two advisories regarding ZOLL Defibrillators. The accompanying documents from the manufacturer describe how to change default configurations on the devices. CVE-2013-7395 states: “ZOLL Defibrillator / Monitor X Series has a default (1) supervisor password and (2) service password, which allows physically proximate attackers to modify device configuration and cause a denial of service (adverse human health effects).” CVE-2007-6756 states: “ZOLL Defibrillator / Monitor M Series, E Series, and R Series have a default password for System Configuration mode, which allows physically proximate attackers to modify device configuration and cause a denial of service (adverse human health effects).” So who is responsible for deploying the fix? The FDA guidance suggests that both hospitals and manufacturers are responsible for vulnerability management. Yet Radcliffe said that makes the problem of deploying patches even more murky. He explained that “if there is a bug in an MRI machine, the hospital will have to pay to have the manufacturer come in and update all the affected machines. Of course, the hospital could install the updates themselves, but they run the risk of losing their warranty. The hospital could also decide they don’t have the budget available to pay to have the patches installed and merely wait.” Those defibrillators are not the only machines that with default passwords that potentially pose a risk. “Most devices have no security applications on them at all. Anyone can just get in and manipulate whatever they want,” stated an unnamed hospital chief information security officer in a McKinsey Report. Forbes looked into how a network-attached printer using the defaults of “admin” and “12345” for a password could be a “near perfect and silent entry point” for hackers. Lastly, Radcliffe addressed how more security on medical devices could cause patients to have less privacy. For example, if a person with an implantable medical device were to die, then “who can look at a log of his or her health before death? That’s a serious privacy concern, but what if it helps doctors find issues with IMDs, or detect evidence of foul play such as hacking?” Source: http://www.networkworld.com/article/2464010/microsoft-subnet/attacker-could-use-default-defibrillator-password-to-launch-denial-of-service.html

Irish Domains hit with denial of service attack

Web-hosting company Irish Domains was the target of a distributed denial of service (DDoS) attack on Friday, incapacitating numerous websites of its client companies. The company said that it had seen “a significant slowdown” on several services following the DDoS attack, whereby an online service is made unavailable by overwhelming it with traffic from multiple sources. The company said the slowdown was affecting email and web for some sites, adding that it “had experienced a 30x increase in inbound network connections”. “We are implementing some countermeasures to divert unwanted traffic but we expect disruption to service to continue for another while,” Irish Domains said. Brightwater Recruitment and Sherry Fitzgerald were among the companies that use the web hosting services services of Irish Domains and thus experienced issues with their sites. There are two types of DDoS attacks: a network-centric attack which overloads a service by using up bandwidth and an application-layer attack which overloads a service or database with application calls.

Israel-Hamas conflict sparks surge in DDoS attacks

As conflict between Israel and the Palestinian militant Islamist organisation Hamas escalates, new research has revealed the impact politics has had on cyberattack trends. Tension between countries and changing political landscapes can now often be linked to cybercrime campaigns worldwide. From constant spats between the US and China to increased targeting of Syrian and Thai targets during political unrest, digital weaponry is now a key tool for groups to broadcast their own political messages, spy on governmental agencies and steal valuable data. In a new report released by Arbor Networks, anonymized traffic and DDoS attack data from over 290 ISPs that have deployed Arbor’s Peakflow SP product — collated and analyzed as part of Arbor’s ATLAS initiative — it appears that DDoS attacks are rising in number and volume as a result of the Israel-Hamas conflict. The graph below depicts the number of reported DDoS attacks initiated against Israel daily over the 1 June to 3 August period this year: Distributed Denial of Service (DDoS) attacks are used to flood a website or service with traffic to the point systems cannot cope, denying other users access to the website. Arbor detected a rise in the number of DDoS attacks targeting Israel in the first week of July, going from an average of 30 attacks per day to an average of 150 attacks initiated per day in July — peaking at 429 attacks on July 21st. Linking these cyberattacks to political situations, 30 June is when Israel publicly attributed the deaths of three kidnapped Israeli teenagers to Hamas, and on 7 July, “Operation Protective Edge” was launched by the country. As the political conflict raged on, so did the frequency of DDoS attacks until a drop occurred on 28 July lasting through 2 August. Arbor says the drop in attacks roughly correlates with cease fire talks which began 27 July. From 28 July through 2 August, there were 192 attacks recorded in total. On 3 August, the number of DDoS attacks rose sharply, with 268 attacks in total. In addition to the number of DDoS attacks over these time periods, the security researchers also noticed an increase in the peak size of these attacks. In the graph below, we can see that in June, no attacks exceeded 12Gbps. In July, seven DDoS attacks exceeded this size, with the largest peaking at 22.56Gbps on 12 July. When cease-fire talks fell apart on 3 August, the largest DDoS attack was recorded at a size of 29Gbps. The duration of DDoS attacks has also increased. In June, the average duration was 20 minutes — with a peak duration of 24 hours — and in July, the average duration was 1 hour 39 minutes. “As the intensity of the Israeli-Hamas conflict has increased, so has the number, size and duration of the DDoS attacks targeting Israel,” the researchers say. “Additionally, it even appears as if the attackers have made an effort to adhere to the “real world” calls for a cease-fire, resuming their attacks when the cease fire fell through.” Source: http://www.zdnet.com/israel-hamas-conflict-sparks-surge-in-ddos-attacks-7000032375/#ftag=RSS14dc6a9

RIA Novosti Website Hit by DDoS Attack

RIA Novosti’s website has fallen foul of a distributed denial-of-service (DDoS) attack by hackers, the agency’s IT specialists reported on Sunday. The mobile version of the website is currently inaccessible. Problems with the website’s full version were also reported for a short period of time. The agency’s terminal for clients has not been hampered. Unidentified hackers first attacked the website of InoSMI. When the attack was neutralized, they attempted to disrupt the work of RIA Novosti’s website. IT specialists are now working to eliminate the disruption that has caused by the attack. This is not the first cyber attack on the news agency. In May 2012, the RIA Novosti website was hit by a DDoS attack from some 2,500 IP-addresses. Another DDoS attack on the agency’s website was carried out in July 2013. Source: http://en.ria.ru/russia/20140803/191676816/RIA-Novosti-Website-Hit-by-Cyber-Attack.html
