Twitter down: Sporadic outage leads to speculation of DDoS attack

The social networking service Twitter suffered sporadic outages Thursday, leading some to speculate about a hacker attack. Access came and went, with reports that users were being affected around the world. In a brief update, the company acknowledged some people were having issues using the service. “Users may be experiencing issues accessing Twitter,” they said in a statement. “Our engineers are currently working to resolve the issue.” A micro-blogging service that allows users to send short messages, Twitter has been likened to an international party line. There are myriad running conversations, to which anyone can contribute. As of March there were 140 million active users who generated over 340 million tweets daily, Twitter says. Not long after its initial message, Twitter said that the issue had been “resolved” and that all services were operational. Users often are quick to turn to Twitter to pose questions about emerging events. But in an ironic twist, Thursday’s outage was initially so pervasive that users couldn’t take to the twitterverse to discuss what was happening. But on message boards, comment fora and other social networking services people voiced their concern. Some wondered if the site had been attacked by a distributed denial of service attack by the hacker group Anonymous. Others bemoaned the lack of access. “I’m losing my mind!” Matt Gio wrote at mashable.com. “I have so much to talk about today and I have an important blog post scheduled.” But some took the outage humourously in stride. Olivia Bovery posted at Facebook that she was “going through withdrawal” and going to step outside. “There is this bright yellow ball in the sky that must be investigated. Seems to be giving off a lot of heat. Wonder what it is.” Moments later she followed up. “Finally, its back up! Back to twitter. Yellow ball will have to wait.

Financial Gain is Main Motivation for Cyber Criminals

Announcing the findings of “The Impact of Cybercrime on Businesses” survey, carried out by Ponemon Institute, Check Point Software Technologies revealed that 65% of the organizations which experienced targeted attacks reported that an attacker’s primary objective was to make a financial gain. Disrupting business operations and stealing customer data were attributed as the next likely motivation for attackers, as stated by 45 % of the surveyed organizations. The report also stated that only around 5% of security attacks were driven by political or ideological agendas. The report, which surveyed 2,618 C-level executives and IT security administrators in the US, United Kingdom, Germany, Hong Kong and Brazil across organizations of various types and sizes, showed that companies reported an average of 66 new security attack attempts per week. Respondents in all countries stated that the most serious consequences of such attacks were disruption of business and loss of sensitive information, including intellectual property and trade secrets. Diminished reputation and impact on brand name were the least of their worries, with the exception of respondents in the UK. Successful attacks could end up costing businesses anywhere between $100,000 and $300,000: the participants estimated the average cost of such an attack at $214,000 USD. Tomer Teller, security evangelist and researcher at Check Point Software Technologies, was quoted in the press release as saying, “Cybercriminals are no longer isolated amateurs. They belong to well-structured organizations, often employing highly-skilled hackers to execute targeted attacks, many of whom receive significant amounts of money depending on the region and nature of the attack.” “For the most part, the goal of attackers is to obtain valuable information. These days, credit card data shares space on the shelves of virtual hacking stores with items such as employee records and Facebook or email log-ins, as well as zero-day exploits that can be stolen and sold on the black market ranging anywhere from $10,000 to $500,000,” he added. While Denial of Service (DoS) attacks were seen as the type of cyber crime that posed the greatest risk to organizations, SQL injections were cited, by 43% of the respondents, as the most serious types of attack organizations had experienced in the last two years, the report stated. Other threats cited in the survey included APTs (Advanced Persistent Threats), botnet Infections and DoS attacks cited by 35%, 33%, and 32% of the respondents respectively. On the threats posed by activities of their employees, organizations, across all the surveyed countries, unanimously cited the use of mobile devices such as smartphones and tablet PCs as the biggest concern, followed by the use of social networks and removable media devices such as USB sticks. Hong Kong and Brazil reported on an average the highest percentage of mobile devices infected through an act of cyber crime, at 25 percent and 23 percent, respectively. The U.S. and Germany had the lowest average of infected mobile devices and machines connected to the network at 11 percent and nine percent respectively. The report found that for protecting themselves from these threats, a majority of organizations have instituted Firewall and Intrusion Prevention solutions. However, at the same time, less than half of the surveyed organizations have implemented the necessary protections to fight botnets and APTs. “Cybercrime has become a business. With bot toolkits for hackers selling today for the mere price of $500, it gives people insight into how big the problem has become, and the importance of implementing preemptive protections to safeguard critical assets,” Teller stated. It was pointed out that only 64% of companies said that they have current training and awareness programs in place to prevent targeted attacks. “While the types of threats and level of concern companies have may vary across regions, the good news is that security awareness is rising,” Dr. Larry Ponemon, chairman and founder, Ponemon Institute, was quoted as saying in the press release. “Across the board, C-level executives reported high levels of concern about targeted attacks and planned to implement security precautions, technology and training to mitigate the risk of targeted attacks.” For fast DDoS protection click here .

Asia to see rise in cloud DDoS security biz

COMMUNICASIA, SINGAPORE–With the rise of cloud services adoption, businesses also have escalating security concerns over distributed denial of service (DDoS) attacks, and that presents an opportunity for carrier service providers to offer cloud-based DDoS protection, which one industry executive adds is set to gain traction in Asia. Among enterprises, the constant discussion around cloud to make it “sexy and pervasive” to customers cannot ignore the question of what happens when the cloud service becomes unavailable due to an attack, said Lau Kok Khiang, director for Asia-Pacific IP division at Alcatel-Lucent. There is hence “strong pent-up demand” for cloud-based DDoS protection, for which carrier cloud services are in a good position to provide, he said. Lau was presenting at the Telco Rising Cloud conference in CommunicAsia here Tuesday. Large attacks have become commonplace, and enterprises are basically losing the arms race in the Internet security space, Lau described. Among the various DDoS attacks in 2011 alone that saw businesses worldwide suffer a “great amount of damage” involved Sony PlayStation Network, the Hong Kong stock exchange, Visa, MasterCard, PayPal, and WordPress, he pointed out. The executive emphasized that cloud-based DDoS security was a “win-win” scenario for both the service provider and enterprise customers. For the service provider, it is a new revenue opportunity, which also complements existing enterprise services such as virtual private network (VPN) and business broadband. Additionally, this could help drive customer stickiness, Lau said. That is because from the customers’ point of view, having cloud-based DDoS protection ensures 24-by-7 availability of the cloud services they use, which mean better safeguards for their enterprise assets such as confidential client data, he added. On the event sidelines, Lau told ZDNet Asia that cloud DDoS security is set to gain traction in Asia, due to increasing awareness of the risks and prevalence of DDoS. This will prompt companies to consider cloud DDoS protection as added security measures, in order to ensure their service availabilities meet customer demands as well as industry-specific regulations. Also, apart from commercial entities, governments in the region are also pushing the message that organizations need to protect themselves from becoming the next victim of an attack, he added, referring to the massive DDoS attacks that disrupted Internet services in Myanmar in November 2010. Another speaker at the conference, Anisha Travis, partner at law firm Webb Henderson, said while the cloud has benefits and opportunities for businesess, they should go into space with “their eyes open”. In other words, they need to understand and prepare for mitigate the major risks associated with cloud, one of which is service levels, she pointed out during her presentation. It is essential that service level agreements (SLAs) are well-drafted for specific service levels and must also include “practical remedies” when there is downtime or outage, Travis advised. Customers cannot rely solely on the service provider, and should do their due diligence in clarifying ownership, consequences, and failures, she added.

Accused British hacker launch DDoS attack and charged in U.S. over LulzSec attacks

A federal grand jury in Los Angeles has indicted a 20-year-old British citizen on charges related to attacks by the LulzSec hacking group on the Fox and PBS television networks and Sony’s film and TV studio, authorities said on Wednesday. Ryan Cleary, who is already jailed in the United Kingdom where he faces prosecution over similar charges, is accused of joining other members of LulzSec in harnessing compromised computers, known as a “botnet,” to steal confidential information, deface websites or attack servers. He was indicted on Tuesday. “Cleary is a skilled hacker. He controlled his own botnet, employed sophisticated methods and his broad geographic scope affected a large number of businesses and individuals,” FBI spokeswoman Laura Eimiller said. LulzSec, an offshoot of the international hacking group Anonymous, has taken credit for hacking attacks on government and private sector websites. Anonymous and its offshoots, including LulzSec and AntiSec, initially focused on fighting attempts at Internet regulation and the blocking of free illegal downloads, but have since taken on such targets as Scientology and the global banking system. The charges come just over two months after accused LulzSec hacker Cody Kretsinger pleaded guilty in U.S. District Court in Los Angeles to taking part in an extensive computer breach of Sony Corp’s Sony Pictures Entertainment. In March, court documents revealed that Anonymous leader “Sabu,” whose real name is Hector Xavier Monsegur, had pleaded guilty to hacking-related charges and provided the FBI with information on fellow hackers. According to the indictment released by the FBI, Cleary and his unnamed co-conspirators hacked into the computer systems of News Corp’s Fox Entertainment Group and Sony Pictures Entertainment and stole confidential user information. The indictment also charges Cleary and his co-conspirators of defacing the PBS website and launching “denial of service” attacks against an online gaming website and Britain’s Serious Organized Crime Agency. Cleary is charged with one count of conspiracy and two counts of unauthorized impairment of a protected computer. He faces a maximum sentence of 25 years in prison if convicted. Eimiller said federal authorities would “allow the prosecution to take its course” against Cleary overseas before deciding whether to seek his extradition to the United States. He is next scheduled to be in court in the U.K. on June 25. Anonymous, and LulzSec in particular, became notorious in late 2010 when they launched what they called the “first cyber war” in retaliation for attempts to shut down the WikiLeaks website. They attacked websites including those of MasterCard Inc, which had tried to block payments to WikiLeaks after apparent pressure from the U.S. government following the release of thousands of diplomatic cables.

Mascow protest against President Vladimir Putin led to indeptendent Russian websites hit with distributed denial-of-service ‘DDoS’ attack

More than 100,000 protesters on Tuesday joined a march against President Vladimir Putin in central Moscow, organizer and radical left-wing activist Sergei Udaltsov told AFP news agency. “There are more than 100,000 people,” Udaltsov said at the rally, called the March of Millions, which police said had drawn 18,000 people. City authorities allowed up to 50,000 to take part in Tuesday’s event, which coincides with the patriotic Russia Day holiday marking the country’s 1990 declaration of independence from Soviet rule. Moscow police said they were sending 12,000 riot officers and interior ministry troops onto the streets of the capital to keep order. The march will take protesters down Moscow’s Boulevard Ring toward Sakharov Avenue, scene of a dramatic demonstration last December against the outcome of disputed parliamentary elections that month. Meanwhile, independent Russian news websites went offline on Tuesday in a suspected attack by pro-government groups, as protesters gathered in Moscow for a march against President Vladimir Putin’s third Kremlin term. The site of the Moscow Echo radio station went down about a half hour before protesters started to gather on central Pushkin Square. The Dozhd (Rain) TV website and that of the prominent opposition Novaya Gazeta twice-weekly newspaper also could not be accessed as the event officially got under way at 0800 GMT. But the websites of Russia’s main media sources ? including Kremlin-allied papers and state-controlled television stations ? were all accessible and operating without delay. A Dozhd newscaster said their station’s website was the victim of a distributed denial-of-service (DDoS) attack of unknown origin. Opposition leaders have been previously blamed attacks on Russian independent media sources on pro-Putin youth groups. A similar attack, which included the inaccessibility of the same websites during the disputed December parliamentary election, was reported but no one claimed responsibility for that attack, AFP reported. The United States on Monday voiced concern after Russian police raided the homes of top protest leaders ahead of the planned mass rally in Moscow. “The United States is deeply concerned by the apparent harassment of Russian political opposition figures on the eve of the planned demonstrations on June 12,” State Department spokeswoman Victoria Nuland told reporters. Police armed with assault rifles carried out a coordinated sweep of the homes of young Russian politicians, who analysts believe represent the biggest threat to ex-KGB spy Putin’s 12-year rule. Nuland also criticized a new law in Russia that imposes “disproportionate penalties” for violating rules on public demonstrations. Russian police were calling in opposition leaders for questioning one hour prior to the planned rally time on Tuesday in a move “clearly designed to take them off the streets during the demonstration,” she said. “Taken together, these measures raise serious questions about the arbitrary use of law enforcement to stifle free speech and free assembly,” she said.

Wawa’s website under suddle DDoS attack

Hackers caused problems for Wawa’s website, www.wawa.com, late Friday, although it appeared to be back to normal by Saturday. Some visitors to the convenience retailer’s site did not see the usual images of hoagies and smoothies and gasoline promotions. Instead, those images were replaced with a cartoon of Adolf Hitler and the name of the group claiming responsibility, UGNazi. According to a report by The Daily Times, Wawa.com visitors were met with a black screen reading “Welcome Nazis, Targets & Reasons” and the drawing of Hitler. Beneath the group’s name was a list of individuals who allegedly hacked the site: Arya Ebrahimi, Justin Martin, Alex Irvin and Thomas Ryan. The group included a link to follow it on Twitter. UGNazi tweeted about high gasoline prices and plans to also hack the convenience store’s gasoline pumps, reported CBS Philly. According to a Courier Post report, the group tweeted, “How much ?#havoc would be caused by shutting down all of the Wawa gas pumps? Love having access to the gas control relay centers .” In a statement provided to CSP Daily News on Saturday, Wawa public relations director Lori Bruce said, “Please be assured that we have no evidence to indicate our website has been breached. Images on our website were not replaced;  however, a domain name server is being intermittently redirected to a nonlegitimate webpage. We have rectified the situation with our domain registrar, but it may take another 24 hours to propagate to all domain name servers. Until then, people trying to visit Wawa.com may see a page other than Wawa.com.” (The website seemed to be displaying normally by Saturday, with no trace of the bogus page evident.) “Unfortunately, today, many well-known brands have become targets for online mischief or worse. We will continue to actively monitor and report this to the proper authorities,” Bruce added. “This obviously had nothing to do with Wawa and it is certainly not something we condone,” she told the Courier-Post. “We will be working with authorities to get to the bottom of this.” Pennsylvania State Police told the paper that the hacking would fall under the purview of the Internet Crimes Task Force. “We did this not only for the fame but for the ‘lulz’ [“laugh out louds”] and the fact that Wawa has scorching high gas prices and receives many complaints daily,” Cosmo, one of the UGNazi hackers, told technology website Softpedia.com. He claimed that the group has gained access to the websites entire database, but that it has not found anything valuable to leak. According to Wikipedia, UGNazi, also known as the Underground Nazi Hacktivist Group, is a computer hacker group that has claimed responsibility for several attacks conducted over the Internet. It is best known for its “Tango Down” distributed denial of service (DDoS) attacks on U.S. government websites and for leaking the personal information of government officials. The Wawa, Pa.-based c-store chain operates 594 stores in Pennsylvania, New Jersey, Delaware, Maryland and Virginia, of which 311 sell fuel.

Indian ISPs targeted in Anonymous censorship protest

The websites of Indian government-run communications company Mahanagar Telephone Nigam and the Internet Service Providers Association of India faced DDoS (distributed denial of service) attacks from Anonymous on Wednesday as some Internet service providers continue to block file-sharing websites following a court order. ISPs are only following the orders of the court which are supreme, said Rajesh Chharia, president of ISPAI, who was doubtful that the association’s website had been affected by the hackers. The Indian arm of Anonymous previously attacked some government websites, and those of some political parties. Last month, users reported that the hackers tinkered with the service of a large ISP, Reliance Communications, redirecting its users from sites like Facebook and Twitter to a protest page. The hackers also claimed to have attacked the website and servers of Reliance, and got access to a large list of URLs blocked by the company. Reliance denied its servers were hacked. The attacks follow a March court order directing ISPs to prevent a newly released local movie from being available online in pirated versions. Some ISPs blocked some file-sharing sites altogether, rather than any offending URLs. The measures taken by the ISPs have differed depending on their interpretation of the order, Chharia said. Some websites such as The Pirate Bay continue to be blocked by some ISPs and carried the message, “This website/URL has been blocked until further notice either pursuant to Court orders or on the Directions issued by the Department of Telecommunications.” Pastebin is also not accessible through some ISPs. Internet service providers are against censorship, and also against piracy, Chharia said. “It is up to the government and various groups to come to a resolution,” he added. The responsibility of intermediaries has been a controversial issue in India, with some Internet companies including Google and Facebook sued in court late last year for objectionable content found on their sites. Their websites have been attacked as blocks on some file-sharing sites continue Anonymous meanwhile plans on June 9 what it describes as non-violent protests across many cities in India against censorship of the Internet in the country. It claims to have already received police permission for some of the protests. The scope of the protests has widened to include demands for changes in the India’s Information Technology Act, which among other things allows the government to block websites under certain conditions, and also allows the removal of online content by notice to ISPs. The government is also in the process of framing rules that will put curbs on freedom on social media, according to the hacker group.

Counting the cost of a DDoS attack

In the past month, the Information Commissioner’s Office (ICO), the Leveson inquiry website, Visa and Virgin Media have all been hit by distributed denial of service (DDoS) attacks. Much had been made of the motives for such attacks, and the methods that attackers use, but what impact do they have on the victim’s finances? John Pescatore, analyst at research firm Gartner, told Computing that there were three main costs associated with attacks. “There is the cost of the outage, as it means that a business’s customers cannot reach them through the internet. Then there is the cost of making the attack stop – and, often, a third cost in the form of a potential extortion fee,” he said. Obviously losses vary, depending on how much revenue is generated directly from a company’s web presence. John Roberts, head of managed services at MSP Redstone, said: “If a betting organisation trades £600m a year – or £2m a day in revenue terms – and 50 per cent of that comes from the web, then they are losing £1m a day.” Any web-dependent organisation within the global 1,000 might incur similar losses, he added. But there are some less obvious victims of these blunt-instrument attacks. “A Scottish football club who were playing in a European match had its website taken down by the opposing teams’ fans with a DDoS attack. The club was not able to generate significant revenue, because a number of its customers were signed up to stream live games on a monthly fee basis. So an organisation as innocuous as a football club can lose hundreds of thousands of pounds as well,” Roberts said. Public-sector bodies can also suffer substantial financial damage through loss of productivity. “There is a cost implication for local government as people will be looking to procure services over the internet. If those services are unavailable, public-sector staff will receive a lot more incoming phone calls,” he said. Other repercussions are harder to assess and quantify. For example, businesses can suffer reputational damage from DDoS attacks, said Andrew Kellett, analyst at research firm Ovum. “With [the attack on] the Serious Organised Crime Authority [SOCA], the issue was that this was not the first time it had been exposed to a DDoS attack. You would have thought that enough resilience would have been built after the first attack to deal with something similar a year later,” he said. But Gartner’s Pescatore said that reputational damage is often less severe than many organisations fear; customers are used to websites not working for any number of other reasons that are not related to DDoS attacks. “There is reputational damage if the website is defaced or if the website is attacked and customers’ financial information is disclosed, but DDoS generally does not have much of a reputational impact,” he argued. Kellett disagreed and emphasised that reputational damage can itself cause financial loss to enterprises, as their customers opt for an alternative service from a similar provider. He warned that DDoS attacks could also be used as cover for a simultaneous assault on the targeted business. “The noise around  DDoS attacks can be used to hide another backdoor-style assault, such as data being stolen from within the organisation. “There is an example of clerical records, including credit card information, being stolen from an organisation when a DDoS attack was taking place. It was a hacktivist attack where the credit card details were used to make donations to a charity. For any organisation protecting those details it would be both embarrassing and expensive, as they could lose customers and have to repay anyone who has had money taken from their accounts,” he said. Pescatore said that, of the three costs typically associated with DDoS attacks, extortion attempts have reduced significantly. “In the last two years, businesses have not paid off extortion attempts and are focusing on putting in place services to mitigate DDoS attacks. Several years ago there were incidents where it was deemed less expensive to pay off the attackers as they would only be asking for €5,000,” he said.

Man arrested for hacking into billing provider

The FBI has arrested hacker “Cosmo”, according to a report by Eduard Kovacs of Softpedia. Cosmo is alleged to be the leader of four-man hacktivist group UGNazi, which took control of the web site of major payment services provider WHMCS just over a week ago. Previously, UGNazi had been known primarily for distributed denial-of-service (DDoS) attacks carried out using its own botnet. Earlier this month, for example, it briefly took down the US Department of Education web site. UGNazi received even more attention when, on 21 May, it hacked into servers belonging to UK billing company WHMCS and copied private internal information, which it posted online two days later. The stolen data included a MySQL dump of the company’s customer database containing nearly 130,000 records, and data from the main server. The hackers gained access to WHMCS’ Twitter account and infiltrated the user forum. The group also carried out DDoS attacks to take down the WHMCS domain for several hours. The UGNazi hackers reportedly used basic social engineering techniques to gain access to the WHMCS domain. One of the hackers, probably Cosmo, phoned WHMCS’s hosting company claiming to be the company’s CEO and correctly answered the security question. They were then given full access to the company’s main server. WHMCS provides payment systems for small to medium-sized web sites. At the time of the intrusion, the customer database contained just under 13,000 credit card numbers, which were encrypted using a symmetrical AES algorithm. Passwords were salted, which should have made them harder to decrypt – but since the salt was recorded directly after the password, not impossible. Following the attack, the hackers spent several days taunting WHMCS. They posted tweets in the name of the company and rewrote some company blog and forum postings. In a statement on PasteBin, UGNazi stated that its motivation for the hack was simply to open the eyes of WHMCS users. The group’s US-based web site is now offline – having been, according to a tweet by Cosmo, seized by the FBI. Members of the group have told Kovacs that they are confident that the FBI will not be able to prove anything in relation to Cosmo. A fifth member left the group shortly before the attack on WHMCS. According to Softpedia, another member of the group hasn’t been online “for the past couple of days”. WHMCS has now reset all passwords for its customer area and warned its customers to be vigilant for ongoing consequences of the hack. Yesterday the company was forced to inform its customers of a further security concern, when a programmer informed WHMCS of a vulnerability in its payment processing system, for which the company released an immediate patch.

DoS crashes updated iPads, iPhones

A denial of service attack has been disclosed in the latest version of Apple iOS. The attack targets Safari in iOS 5.1.1 and a proof of concept was published online. Alienvault security researcher Alberto Ortega said the attack may also affect previous versions of the Apple operating system. The attack was successfully demonstrated on iPhone, iPad and iPod Touch. Ortega said the error was a “step to achieve a real exploitation”. “iOS has a lot of mitigations to avoid successful exploitation,” Ortega said. “This software has errors and holes but you will need to bypass those hard mitigations and find more weaknesses  to have something “usable’.” Ortega reported the error to Apple at the time of disclosure but had no response from the notoriously security silent company. “When JavaScript function match() gets a big buffer as parameter the browser unexpectedly crashes. By extension, the function search() is affected too,” Ortega said in the advisory. Source: http://www.crn.com.au/News/302620,dos-crashes-updated-ipads-iphones.aspx
