Turkish banks & government sites under ‘intense’ DDoS attacks on Christmas holidays

Turkey is suffering from a wave of cyber-attacks on financial and government websites which intensified over Christmas, resulting in the temporary disruption of credit card transactions. A video released this week and attributed to Anonymous vowed retribution for Ankara’s alleged ties with ISIS. The attacks on Turkish servers have been persistent in recent weeks, but on Christmas day Turkish banks suffered a website outage and reportedly saw sporadic disruption to credit card transactions. Isbank, Garanti and Ziraat Bank were among the targets, local media reported. “It is hard to determine where these attacks are coming from, with detailed work it will be understood whether these attacks are carried out by hackers or by certain groups” said the Minister of Communications Binali Yildrim. The DDoS attacks on Turkey’s “.tr” domain, Yildrim said were “serious” as they include domains of ministries, banks, and the military. The ministry asked Ankara’s Middle East Technical University (ODTU), which operates the “.tr” domain to step up security measures. ODTU’s analysis said that the attacks are coming from “organized sources” outside Turkey. Turkish Telecom, in a statement to Hurriyet daily, said that they are now on “24/7 defense” as they acknowledged facing “thousands of attacks.” Most Turkish institutions use Turk Telekom as their service provider. “The attacks are serious,” a spokesman for internet provider Turk Telekom, Onur Oz, told Reuters. “But the target is not Turk Telekom. Instead, banks and public institutions are under heavy attack.” The banking sector is one of the fastest growing areas of online services in Turkey and equates roughly to 1.5-2 billion transactions daily, according to Hurriyet. More than 85 percent of daily banking transactions in Turkey are carried out on digital platforms. “These attacks began two weeks ago but have intensified over the past two days,” said Burak Atakani, a network specialist from Istanbul Technical University. Some Turkish media outlets have speculated that the cyber-attacks might have been launched by Russia in retaliation to the downing of a Russian bomber by a Turkish fighter jet late in November over Syrian airspace. Meanwhile in a video, released this week allegedly by hacktivist collective Anonymous, hackers promised to take on the Turkish government over its alleged shady deals with Islamic State (IS, formerly ISIS/ISIL) terrorist organization. Anonymous especially threatened to bombard the banking sector. “Turkey is supporting Daesh [the Arabic name for IS] by buying oil from them, and hospitalizing their fighters. We won’t accept that [Recep Tayyip] Erdogan, the leader of Turkey, will help [IS] any longer,” says a video message from the group. “We will continue attacking your internet, your root DNS, your banks and take your government sites down. After the root DNS, we will start to hit your airports, military assets and private state connections. We will destroy your critical banking infrastructure.” Special Cyber government security units within the Information and Communication Technologies Authority (ICTA) and the Telecommunications Directorate (TIB) have been deployed to stop the attacks. “Turkey is not in a position to be powerless in the face of these attacks,” said Customs and Trade Minister, Bulent Tufenkci. “I think that we’ll have necessary response.” Source: https://www.rt.com/news/327119-turkey-banks-cyber-attacks/

Anonymous Claims Responsibility For 40 Gbps DDoS Attack on Turkish Servers

The online hacktivist Anonymous has claimed the responsibility for a massive 40Gbps DDoS attack on Turkish DNS Servers under NIC.tr — The reason behind the attack is that Turkey is allegedly supporting and aiding the Daesh or ISIS/ISIL terrorist group. In a video uploaded by Anonymous, the hacktivists said that their attack on Turkish servers was part of their ongoing operation #OpISIS. According to the video message, “We won’t accept that Erdogan, the leader of Turkey, will help ISIS any longer. The news media has already stated that Turkey’s Internet has been the victim of massive DDOS attacks . This lead Turkey to shut down it’s internet borders and deny anybody outside the country to access Turkish websites.” The hacktivists also warned the government that if Turkey didn’t stop aiding Daesh or ISIS the attacks will continue and target airports, banks, government and military servers. “If you don’t stop supporting ISIS, we will continue attacking your internet, your root DNS, your banks and take your government sites down. After the root DNS we will start to hit your airports, military assets and private state connections. We will destroy your critical banking infrastructure. Stop this insanity now Turkey. Your fate is in your own hands,” said Anonymous. The cyber attack on Turkish root DNS servers took place last week which forced 40,000 .tr domains to go offline. Though the targeted domains were back online they same day however the accesses to those sites was kept limited. The state of Turkey has been accused of aiding and buying oil from the Daesh terrorist group. Some also accuse Turkey of being a safe passage for the groups recruitment in Syria.

Xbox Live Suffers DDoS Disruption, Playstation Network May Be Next

A DDoS attack initiated by grey-hat hacker group Phantom Squad may have taken Microsoft’s Xbox Live online network offline for at least 3 hours today. If the hacker group’s threats are to believed, Sony’s PlayStation Network (PSN) may be next. Gamers, look away. This is going to make for painful reading. For the second time in two years, a hacker group may be disrupting two of the most popular gaming networks in the console gaming world, Xbox Live and the PlayStation Network. Hacked reported on the DDoS threats made by Phantom Squad a few days ago, after a series of tweets posted by the hacker group that also took credit for knocking Reddit offline recently. In a case of history repeating itself, the group is doing what infamous hacking group Lizard Squad did last year in December, disrupting gamers’ plans of going online with their consoles by taking down Xbox Live and PSN for several days last year. While the new group Phantom Squad threatened to take down the gaming networks during Christmas, Xbox Live suffered an outage in certain parts around the world for a few years today. To nobody’s surprise, Phantom Squad took credit for the outage. An update posted today on Xbox’s status website read: Hey Xbox members, are you having trouble purchasing or managing your subscriptions for Xbox Live? Are you also having an issue with signing into Xbox Live? We are aware of these issues and are working to get it fixed ASAP! Thank you for being patient while we work. We’ll post another update when more information becomes available. The message made no reference to any disruptions or DDoS attacks targeting the network although Microsoft nor Sony seldom acknowledge such attacks, even if they were bearing the brunt of such attacks. For now, Xbox Live Status shows all services are up and running and it is likely that Microsoft has found an IP range or two to block the DDoS requests flooding the servers, a common defense strategy against such attacks. Meanwhile, Phantom Squad has claimed that it will DDoS both gaming networks this Christmas Day. So we are going to DDoS Xbox&PSN on Christmas Day We Dont Joke We Are Always Watching Christmas Day PSN&Xbox This Is Not A Bluff #Phantom — PhantomSquad (@PhantomLair) December 18, 2015 The hacking group claims that the disruptions are to bring attention to the lack of cybersecurity in the gaming networks but gamers will argue the group is doing it simply to annoy a large population of console gamers looking to wind down and play games during the holidays. Hacked has previously reported on several disruptive malicious hackers, including those from Lizard Squad who have been arrested not long after their antics from Christmas last year. One of the suspects was arrested in the UK in January this year while another was apprehended as a part of a wider operation in March 2015. Hacked will keep you updated on this story as it unfolds in the week leading to Christmas. Source: https://hacked.com/xbox-live-suffers-ddos-disruption-playstation-network-may-next/

Hacker squad plans DDoS attacks on PlayStation Network, Xbox Live this Christmas

Hacker group Phantom Squad plans to shut down Xbox Live and PlayStation Network on Christmas. Forget the Grinch, there’s someone else who wants to steal Christmas. Phantom Squad, an online hacker group, has threatened to shut down Xbox Live and the PlayStation Network this Christmas by unleashing a series of DDoS (distributed denial of service) attacks — coordinated barrages of falsified incoming server traffic that causes the system to crash. DATA BREACHES AND CYBERATTACKS IN 2015 “We are going to shut down Xbox Live and PSN this year on Christmas,” the hackers tweeted. “And we are going to keep them down for one week straight. #DramaAlert.” We are going to shut down Xbox live and PSN this year on christmas. And we are going to keep them down for one week straight #DramaAlert — Phantom Squad (@PhantomSqaud) December 9, 2015 This could cause a big problem, because a lot of people are expecting to receive new gaming consoles on Dec. 25. If Phantom Squad is successful, this would be the second year in a row that these gaming networks go offline. Last year, the infamous hacker group Lizard Squad took credit for shutting down Xbox Live and PSN for two days. The group demanded more retweets and Twitter followers in exchange for restoring the servers. Phantom Squad, which said it has no relation to Lizard Squad, claims they’ve previously performed smaller outages on the gaming community servers, as well as other website such as Reddit. The group also explained in a tweet why it is that they perform these attacks. “I get asked a lot on why we do this? Why do we take down PSN and Xbox Live?” the tweet reads. “Because cyber security does not exist.” Sony and Microsoft have both received a series of attacks over the past year, but it’s still unknown what tactics they’ve developed to try and avoid these issues. Kim Dotcom, the infamous Internet entrepreneur behind Megeupload, has warned Sony and Microsoft that the attack could be avoided if they update their servers. “Warning @Sony & @Microsoft. You had 1 year to upgrade your networks. If Lizard Squad takes down PSN & XBOX this Xmas, we’ll be pissed! RT!,” Dotcom tweeted. Dotcom, who is also a gamer, helped stop last year’s attack by promising the hackers 3,000 accounts on his encrypted upload service Mega. While Sony and Microsoft work on strengthening their servers, people who bought a console as a gift this Christmas can unbox it, plug it in, and download all the updates as soon as they buy it. This process will let them at least play games offline on Christmas. Otherwise, if the hackers release a DDoS attack, the console will be useless without being powered on and updated.

Boston internet service disrupted briefly by DDoS attack

Internet service in Boston was disrupted on Tuesday in what is being called a “minor act of cybervandalism,” according to the Boston Herald . The outage, affecting city agencies and the police and fire departments, was “short, but widespread,” said Mayor Martin J. Walsh. A distributed denial of service (DDoS) attack that caused computers worldwide to redirect network traffic to City Hall computers is cited as the method by which web connections were shuttered. While Jascha Franklin-Hodge, the city’s CIO, dismissed the attack as “a minor act of cybervandalism,” the incident is another example of an attack method becoming increasingly common and illustrates the vulnerabilities enterprises face on a daily basis. Experts explained that as the attack harvests no data, it might have been retribution or an attacker’s attempt to gain notoriety. Franklin-Hodge said his team was able to restore service within 20 minutes. Source: http://www.scmagazine.com/boston-officials-call-ddos-attack-on-internet-service-a-minor-act/article/460203/

Web host Moonfruit defies Armada DDoS crew … by (temporarily) defeating itself

Move follows 45-minute attack last Thursday Web host Moonfruit last night began putting its systems back online after taking down customers’ sites in order to upgrade defences in the face of a threatened DDoS attack, with the firm blaming a recent assault (which prompted the self-takedown) on the Armada Collective crew.…

Moonfruit takes down thousands of sites after a DDoS attack

Moonfruit, a free website builder, has taken thousands of business and personal websites offline following a distributed denial of service (DDoS) attack. The company’s users are disappointed by the slow pace at which it has communicated the problem, and the way it’s being handled. The company said it had been threatened with a cyber-attack and had decided to make its customers’ websites unavailable for “up to 12 hours” to make infrastructure changes. In a statement on the Moonfruit website it was said that the company was actually attacked by a hacker group called the Armada Collective, which DDoSed the site for about 45 mintes. One business owner told the BBC it was “very bad timing”. Film-maker Reece de Ville said: “They have been slow to communicate via their website what is going on.” “I’m going to have hundreds of people finding my site today but not being able to access it. I could be losing out on a lot of money from potential clients, and they may not come back if they think the company has gone. It’s incredibly bad timing, especially for businesses selling Christmas cards and gifts on their website.” In an email to its customers, the company apologised for giving them “short notice” that their websites would be offline. “We have been working with law enforcement agencies regarding this matter and have spared no time or expense in ensuring we complete the work as quickly as possible,” the company’s director, Matt Casey, said in the official statement. Industry reaction Ron Symons, regional director at cyber security specialist A10 Networks said: “Moonfruit has responded in the best possible way to this threat by taking its services offline. As the attack it suffered last week shows, distributed denial of service (DDoS) is extremely difficult to prevent. More worryingly, DDoS attacks frequently act as smokescreens hiding more invasive attacks as hackers exploit unguarded system backdoors to steal sensitive data. “By making this bold decision to pre-empt another incident, Moonfruit stands a much better chance of protecting its clients’ private data. The shutdown may be inconvenient now, but by ensuring its infrastructure is equipped to deal with today’s increasingly powerful cyber attacks Moonfruit is acting in the best interests of those using its services.” SEE ALSO: Throwback Thursday: Why Apple is called Apple Dave Larson, Chief Operating Officer at Corero Network Security said: “Unfortunately, the sheer size and scale of hosting or data center operator network infrastructures and their massive customer base presents an incredibly attractive attack surface due to the multiple entry points and significant aggregate bandwidth that acts as a conduit for a damaging and disruptive DDoS attack. “As enterprises of all sizes increasingly rely on hosted critical infrastructure or services, they are placing themselves at even greater risk from these devastating DDoS attacks – even as an indirect target.” Source: http://www.itproportal.com/2015/12/14/moonfruit-takes-down-thousands-of-sites-after-a-ddos-attack/#ixzz3uLEOSJCP
