Novosti-Armenia and ARKA news agencies come Tuesday under heavy DDoS-attacks

The websites of Novosti-Armenia (newsarmenia.am) and ARKA (arka.am) news agencies came Tuesday under heavy DDoS-attacks, hampering access to these resources for half an hour. An inquiry found that the attacks were carried out from Russian IP addresses, but this does not mean that the order came from that country. The administrations of both websites have managed to eliminate the problem. DDoS attack is short for Distributed Denial of Service Attack. DDoS is characterized by an explicit attempt by attackers to prevent legitimate users of a service from using that service. There are two general forms of DoS attacks: those that crash services and those that flood services. The most serious attacks are distributed   and in   many or most cases involve forging of IP sender addresses so that  the location of the attacking machines cannot easily be identified, nor can filtering be done based on the source address.

Finnish Defense Ministry Hit by DDoS Cyberattack

Finland’s Ministry of Defence (MoD) is reviewing its IT security infrastructure in the wake of a distributed denial of service (DDoS) attack on its main website. The attack was launched hours before Finnish President Sauli Niinistö met with Russian President Vladimir Putin in Moscow on March 22 to discuss regional security issues and the implementation of deeper cooperation on border defense. Initial investigations by the National Cyber Defense Center (NCDC) are examining the possibility that the cyberattack may have been launched from Russia to coincide with high-level, inter-government talks. Similar DDoS attacks launched against public and private organizations in Sweden in March had traced the servers to Russia. Niinistö met with US President Barack Obama in Washington on April 1. The meeting took place during the international Nuclear Security Summit hosted by the US president. Finland’s MoD confirmed that the sustained DDoS attack, which lasted more than three hours, was the second such cyberattack against its online IT infrastructure in 2016. The MoD responded by diverting traffic from its main site defmin.fi to a temporary site. The previous DDoS attack took place Feb. 27 and lasted nearly five hours. Other key government department websites, including finance, social affairs and health, agriculture and forestry, and the Council of State office, were targeted in  simultaneous attacks. The timing of the latest DDoS attack is significant, coming as Finnish and US governments finalize plans connected to joint military exercises in Finland.

Notorious pro-US hacker Jester diverts DoS attack towards Israeli spy service Mossad

A high-profile US hacker has turned an attack on his website into an assault against the Israeli intelligence service. ‘The Jester’ – or th3j35t3r – claims that he diverted an attempt to overload his website to assault Mossad’s online presence. Haaretz reported that Jester’s website – jesterscourt.cc – was the victim of a denial of service (DoS) attack on the night of 1 April. In a tweet, Jester announced that he had diverted the hacker’s attack by simply changing the IP address his website was registered on. When asked why he picked Mossad by one of his 74,400 Twitter followers, Jester replied “Because they can look after themselves perfectly well.” On his blog, Jester claims to have used this technique before. In a post called Offensive Counter Measures – Be Like Water, Jester details the steps he took to divert another DoS attack, which he alleges was carried out by Anonymous, towards websites linked with the Occupy movement. According to Haaratz, Israel’s Information and Communications Technology Authority said Mossad’s website had not seen any irregularities or disruptions of service. At the time of writing, Mossad’s website was working, but IBTimes UK could not confirm whether it had suffered any downtime. However, The Jester’s website was not working. Anti-ISIS, anti-Anonymous Jester is one of the hacking community’s most high-profile members. What is a DoS attack? During a denial of service (DoS) or a distributed denial of service (DoS) attack, hackers attempt to overload a website’s connections by sending in data requests from multiple sources. Most often hackers use a ‘botnet’ – internet-connected PCs that are compromised by malware – to send in the requests to visit the site, without the users’ knowledge. The huge number of requests, which can reach thousands per second, overload the ability of a website’s server to respond, eventually causing an error message to appear instead of the site’s pages. Making a DDoS is relatively simple. Botnets are available to hire on websites not reachable via search engines (deep web) or on encrypted websites (the dark web). Jester’s career as a vigilante hacker appears to have started in 2010, when he claimed to have been involved in an attack on the Wikileaks website. That year, the New York Times reported Jester was a a former military contractor who had worked with US special forces. Since then, Jester has developed a reputation as a pro-US hacker vigilante and cybersecurity expert. Through writing his own blog on cybersecurity, he gives talks on the subject through text chat to keep his identity a secret, and is known for attacking websites linked to Hamas and Islamic State (Isis). Jester has also attacked websites used by the Occupy movement and Anonymous – whom he described as “pathetic terrorist sympathizing buttholes”. He claims to have caused more than 180 websites to go offline since 2010. Jester was listed as one of Time magazine’s “most influential people on the internet” in March 2015.

Coinkite Is Closing Down Its Web Wallet Citing Legal and DDoS Issues

Coinkite, the popular wallet and hardware payment network service provider, has announced it is closing down its web wallet to focus on other projects after legal issues and DDoS attacks have impeded the use of the wallet. Hardware products focus After a noticeable lack in posting on their blog after incredibly frequent posting over the last three years, Coinkite CT r:   24 has announced it is shutting down its web wallet service. Users of the service need not worry about the hardware aspect of Coinkite, as that will remain unaffected, and the team in fact hopes to expand it. “We are winding down the web wallet part of Coinkite so that our team can focus on a number of new products that are more decentralized and embodied as hardware products. We’re still big Bitcoin fans, supporters and Hodlrs, and although Coinkite has been great adventure in the SaaS business, we want to spend more time where our heart is, hardware products, software-”not-as-a-service”, and other exciting new possibilities.” Under DDoS since the first month Coinkite cited the legal issues associated with being a centralized Bitcoin CT r:   8 service, and hence the financial strain brought about by lawyers, and non-stop DDoS-ing since launch for the closing down of the service. “Being a centralized bitcoin service does attract attention from state actors and other well funded pains in the butt, and as a matter of fact, we’ve been under DDoS since the first month we launched—over three years–yay. Plus we have put real fiat dollars into our lawyers’ pockets, to defend our customers from their own governments. This is not what we love to do, which is coding and delivering awesome services.” Programmers-turned-businessmen an issue Part of the issue in the cryptocurrency industry is that many of those who are choosing to create businesses in this newly-fledged sector, are fundamentally programmers, and as such are ill-equipped to deal with the likes of lawyers and regulators. The simple solution to this problem is greater co-operation between the financial industry and the cryptocurrency industry. The financial sector has been around for far, far longer than the cryptocurrency industry. It has the infrastructure, processes, and people already in place to deal with a lot of the issues facing these programmers-turned-businessmen, and if more startups are to succeed, they are going to need to implement them.

The Anonymous ‘war’ on Donald Trump is a complete disaster

The “total war” that Anonymous declared earlier this month against Donald Trump has quickly devolved into a civil war among hackers fighting within the group and pro-Trump supporters who are trolling them within their chat rooms. In early March, hackers affiliated with Anonymous tried to reboot their Operation Trump campaign by calling for everyone to take down Trump’s websites in a coordinated effort on April 1. Almost immediately, the initiative was criticized by people within Anonymous as irresponsible and “cringeworthy,” but a dedicated group apparently moved on with the plan. It’s April 1: Many of the GOP frontrunner’s sites are still standing, there are now two competing OpTrump chat rooms with totally different missions, and one of them has been flooded with pro-Trump supporters and others leaving trolling comments like “Hitler did nothing wrong.” In short: The so-called war seems to be a complete disaster. ‘A mess is happening’ It’s unclear when the split between Anonymous factions occurred, but it seems to have happened sometime after a hacker named Beemsee, who has been leading the original OpTrump effort, released a new statement claiming that attacking Trump’s websites was all a ruse for publicity around April Fools’ Day. “There is no DDoS,” Beemsee and two other hackers wrote, using the acronym for a distributed denial-of-service attack, a tactic used to overload a website. “It’s only purpose was to gain attention, which this Operation needs. … the point of this Operation is not to attack Donald Trump. Instead, it is going to try to give citizens some insight.” Beemsee and their cohorts say in their statement that people should try and capture “the darker nature of Trump’s supporters” and post it on social media sites with hashtags like #OpTrump and #Trump2016. But a hacker called AnonymousLoyalist disagreed. In a competing statement, the hacker wrote that they moved to a “far more organized channel, which has already seen unsurprisingly large amounts of success.” That channel is #OpTrump2016, but it was unclear exactly what that success boiled down to. When Tech Insider viewed the #OpTrump2016 chat room on Friday, it was an unorganized mess. Most Anonymous chat rooms are moderated in some way, and people usually get kicked out for spamming or posting nonsense. But it appeared to be flooded with trolls intent on calling them children, “social justice warriors,” and, more often than not, homophobic slurs. “A mess is happening,” wrote one user in #OpTrump, expressing a shared frustration among others in Beemsee’s chat room. The ‘war’ goes on It was clear on Friday that at least some of Trump’s websites were indeed under cyberattack. The website CitizensForTrump.com is currently unreachable, and the site for Trump’s hotels brought up an error for a few seconds before pulling up a cached version powered by CloudFlare, a service that protects from attacks like this. Anonymous may be able to bring down some of Trump’s unprotected websites, but it will almost certainly come back online after a few hours or days. And many of his other sites are probably not at risk at all, since Tech Insider previously spoke with CloudFlare CEO Matthew Prince, and he wasn’t particularly worried. “DDoS attacks are not particularly sophisticated cyber attacks,” Prince said. “They are sort of the functional equivalent of a caveman with a club.” A representative for Trump did not immediately respond to a request for comment from Tech Insider, but spokeswoman Hope Hicks previously told Tech Insider: “The government and law-enforcement authorities are seeking the arrest of the people responsible for attempting to illegally hack Mr. Trump’s accounts and telephone information.” Depending on who you believe in Anonymous, the plan is a coordinated DDoS attack or a social-media shaming campaign against Trump’s supporters. But Beemsee left open the possibility of something else, perhaps an actual way to take over one of their targeted websites — which the hacker collective has been scanning for vulnerabilities since the beginning. “This is NOT the last time you hear of this operation,” Beemsee wrote. “We will be watching, and will act when the time is right.” Source: http://www.businessinsider.com/anonymous-war-donald-trump-fail-2016-4

Bitcoin Startup Quits Operation Due to Never-Ending DDoS Attacks

Bitcoin’s Secure Wallet Service Coinkite Inc. Closing Down due to never-ending DDoS Attacks and Governmental Nagging Bitcoin exchanges around the world face cyber attacks every now and then, some owners give up while some fight back . In the case of Bitcoin startup Coinkite Inc., it is now officially announced that its secure wallet service, which started in 2012, will be closed within the next 30 days. It has also been made clear that customers must withdraw funds from their wallets by the end of this period. If any of the users fail to do so then their Bitcoin will be automatically credited to them. Prior to closing down all of the services, its TOR accessibility and application program interface of Coinkite will be closed for 14 days while their annual pre-paid plans’ prorated balances will continue to be refunded. The startup was under DDoS attacks for last three years The company now aims to focus upon hardware-oriented products such as the upcoming physical Bitcoin project Opendime. It will be a full-fledged standalone Bitcoin terminal or hardware wallet that will be equipped with a printer as well as QR scanner. Moreover, the company will be focusing upon hardware products for security optimization and authentication, all-purpose standalone Bitcoin solutions and services for hosting Bitcoin hot wallets. Since its inception, Coinkite was marketed as the most convenient and secure way to accept and exchange Bitcoin, the digital currency. The company claimed that it provided users the world’s “most advanced web wallet system.” It was considered a system that empowered customers and merchants to “BUY, SELL, ACCEPT and STORE Bitcoins and other cryptocurrencies, in both the online and physical worlds.” Why is Coinkite Closing the Secure Wallet Service NOW? The decision apparently is the outcome of the constant harassment that the online Bitcoin wallet service has been dealing with. In a blog post , it was revealed by the company that they had been receiving Distributed Denial of Service or DDoS attacks constantly over the past three years. They also have become tired of the attempts by governmental agencies for interrupting into their clients’ privacy. The CEO of the company Rodolfo Novak told CoinDesk that they wanted to shift their focus from software to hardware because their meager resources were being drained further by the “bullshit” that they have been experiencing. “We want to write software, not deal with lawyers and DDoSing…One of the main issues with SaaS is all the free users and need support and we want to provide good support. All these things have costs,” clarified Novak. Source: https://www.hackread.com/bitcoin-exchange-ddos-attacks/

D.O.J. Charges Iran-Sponsored Hackers with Dozens of DDoS Attacks on Major Financial Institutions

No less than 46 U.S. financial institutions, as well as a dam in New York, were allegedly targeted. On Thursday morning, the Department of Justice unsealed an indictment against seven Iranian citizens allegedly funded by the Islamic Revolutionary Guard Corps, accusing them of launching a coordinated cyber-attack against a minimum of 46 American financial institutions, as well as a major New York dam. In a press conference with some of American law enforcement’s heaviest hitters, including F.B.I. director James Comey and U.S. district attorney Preet Bharara , Attorney General Loretta Lynch announced that members of two Iran-based computer companies, ITSecTeam and the Mersad Company, had launched coordinated distributed denial of service (DDoS) attacks against the Web sites of dozens of financial institutions, including the New York Stock Exchange, Bank of America, Capital One, ING, and AT&T, disabling them and preventing their customers from accessing their accounts. In addition, one of the alleged hackers, Hamid Firoozi , was said to have illegally accessed a computer in charge of the Bowman Dam in Rye, New York, giving him the ability to remotely control its operations and potentially cause “a threat to public health or safety.” According to the Department of Justice, the two groups received funding from the Islamic Revolutionary Guard, the elite government militia tasked with defending Islamic law in Iran. Lynch said in a statement that the attacks not only cost these companies “tens of millions of dollars” to restore their Web sites, but highlighted how foreign cyber-attacks have become a major threat to U.S. national security. “In unsealing this indictment, the Department of Justice is sending a powerful message: that we will not allow any individual, group, or nation to sabotage American financial institutions or undermine the integrity of fair competition in the operation of the free market,” she said in the prepared statement. According to the indictment, the DDoS attacks took place over 176 days between 2011 and 2013. The attacks on U.S. targets took place after Iran’s nuclear capabilities were sabotaged by the Stuxnet virus, believed to have been a joint effort between the U.S. and Israeli governments, in mid-2010.   The indictment also comes after a series of high-profile cyber-attacks on the United States government. In 2014 alone, the government experienced more than 61,000 attacks on their computer systems, affecting several administrative agencies such as the State Department, the Energy Department, and the White House. Last year, the Office of Personnel Management (O.P.M.) was the target of the largest attack to date, in which Chinese hackers stole sensitive personal information from 21.5 million past and present government employees. During the press conference Thursday morning, Comey said that the indictment was meant to show the world that the U.S. government was ready to respond to foreign-based cyber-attacks, no matter where they came from or the scale of the attack. “By calling out the individuals and nations who use cyber-attacks to threaten American enterprise, as we have done in this indictment, we will change behavior,” he said.   Source: http://www.vanityfair.com/news/2016/03/doj-iran-hacker-indictment
