DDoS Attack on Voat due to Reddit

Voat was just a small Reddit knock-off before last week — but now it’s becoming overloaded as people threaten to leave the bigger site So many people are leaving Reddit that its closest competitor crashed and had to ask for donations to stay up. Many users of the site protested and left when last week it banned five subreddits for harassment. And since, users have been making good on threats to leave the site — going instead to a Swiss clone of the site, Voat. That site look almost exactly the same as Reddit, and features many of the same communities. But it is committed to a rule of “no censorship” — previously Reddit’s attitude, but  one that it has moved away from as it has attempted to reduce the harassment and abuse on the site. So many people have moved to the Swiss knock-off that it has been down entirely many times since the Reddit bans. In response, the site asked for donations in bitcoin to pay for extra technology to keep the site up. That doesn’t seem to have worked, and the site says that it is now under a distributed denial of service attack, where users send a flood of requests to a website to take it down. But despite the problems, the site now has more than twice as many users as it did late last mnth, according to the site’s Twitter account. It had over 96,000 registered users last night, it said — far from the 172 million unique visitors that went to Reddit in the last month, but up many times over recent weeks. Voat’s founder said that the site was “not ready for such a huge influx of new users” and that it hadn’t “prepared for such a large and sudden increase either”. “We are sorry to see Reddit change like this, in this way, in such an accelerated fashion,” Atko wrote. “We would have never anticipated such events.” Source: http://www.independent.co.uk/life-style/gadgets-and-tech/news/reddit-alternative-breaks-because-so-many-people-leave-site-after-harassment-scandal-10321474.html

Anonymous Hijacks Thousands of Insecure Routers to Power Its DDoS Tools

Lack of some elementary security measures can risk your router’s security and this has stemmed to grow into a large-scale denial-of-service (DDoS) attacks using these hacker-controlled routers. A web security firm Incapsula has discovered a new router based botnet Mr Black while investigating some DDoS attacks against its customers since this December. Hackers exploited routers’ negligent security measures to launch these attacks all over the world. According to this report published by the security firm, the routers made by Ubiquiti Networks had DDoS malware installed on them. The routers were not hacked due to some vulnerability in the hardware. Instead, it happened because of the deployment of the router in an insecure manner that exposed their management interfaces using the default credentials over SSH and HTTP. The routers that were inspected were found to have 4 versions of Mr Black, a DDoS program and altogether thirty-seven variations of Mr Black were detected. Other DDoS programs included DoFloo, Mayday and Skynet (a remote sensing tool). In some earlier versions of the report, Incapsula said that it believed that the hacktivist group Anonymous was one of the few groups those used the compromised routers. It is yet not clear that why Anonymous was highlighted in the report, but it is certain that few people who call themselves “Anonymous” were using the routers. The original article on the Daily Dot was edited to remove the fact that botnet directs to irc (dot) anonops (dot) com. Total 40,269 different IP addresses were detected from 1,600 ISPs spread across 109 countries. The main affected countries were Thailand (64%), Brazil (21%), United States (4%) and India (3%). To control these routers, 60 servers were hacked and majority of these were in China and the U.S. To save themselves from the DDoS attacks, users must make sure that their routers’ management interfaces aren’t exposed over HTTP or SSH to the internet. They can also use some tools available to scan their router’s IP for open ports and change their default login credentials.

DD4BC Shifts Focus to Businesses, Continues DDoS Attack

Cybercriminals and extortionists demanding Bitcoin as ransom is on the rise these days. Due to the easy of transfer and pseudonymity associated with Bitcoin transactions, it has become the currency of choice for them. We have been hearing about ransomware, hacking incidents where sensitive data is stolen from computers and even extortion by threatening to physically harm an individual, the only common factor in all these cases is the ransom, to be paid in Bitcoin. There is one such cybercriminal group called DD4BC who have made it a regular habit to launch Distributed Denial of Service (DDoS) attacks on the websites belonging to Scandinavian companies. Once they launch an initial DDoS attack, they will blackmail these companies to pay about 40 bitcoins to avoid further attacks on their IT infrastructure. In most cases, the group sends out emails to the targeted firm within hours of launching the first DDoS attack. These emails, demanding ransom in Bitcoins also promises the victims that it is a one-time thing and if they pay the ransom, DD4BC will not attack them again. DD4BC also claims in the mail that even though they do bad things, they are going to keep their word. It is surprising that the group which was targeting European banks and financial institutions all these days has suddenly shifted their target to businesses in Scandinavia. Recently DD4BC allegedly tried to extort money from Bitalo Bitcoin Exchange – 1 BTC in exchange for information on how to prevent DDoS attack. But the plan seemed to backfire when the CEO of the Exchange, Martin Albert announced a bounty of 100 BTC for information about the person/people behind DD4BC. Among the list of Bitcoin sites targeted by DD4BC includes CEX.io and Bitcoin sports book Nitrogen Sports. Recently an Australian company was hacked into by unidentified perpetrators. They allegedly stole sensitive data, asking for ransom. They have also threatened to harm family members of one of the top officials from that company.

DD4BC Shifts Focus to Businesses, Continues DDoS Attack

DDoS attacks are a growing digital threat to freedom of expression in Latin America

The media and Latin American journalists are starting to experience firsthand what until recently seemed to be the exclusive concern of US, European or Asian media outlets: cyberattacks.? This type of online criminal activity, known as Distributed Denial of Service (DDoS), is the other side of technological advances that aim to maximize flow of information online.? Cybercrime legislation is backward and broken in Latin America, where the lack of a culture of information security or economic resources of journalists and media outlets ensures that attacks are successful.? One of the most recent cases occurred in Mexico, where minutes after publishing an investigation about the alleged responsibility of federal police in extrajudicial executions of several young people in Apatzingan, a town in the state of Michoacan, the Aristegui Noticias site was out of services for hours, a victim of a DDoS attack.? The Knight Center for Journalism in the Americas consulted Robert Guerra, an expert on cyber security and Internet freedom, and Luis Horacio Najera, a Mexican journalist and expert in the field, on the consequences of these attacks for media companies.? “The main consequence of a cyber attack in the context of Latin America is the reduction of critical spaces that encourage debate or the exposure of misconduct and abuse of power, like corruption,” Guerra said. Guerra, founder of Privaterra, an organization based in Canada that advises private companies and NGOs on data privacy, believes that “any attack, whether cyber or physical, deteriorates freedom of expression and of the press in the country where it occurs.” In the context of countries like Mexico, where media workers are victims of assassinations, kidnappings and threats, this “silent war” on the Internet is presented as a new alarm when speaking about freedom of expression and of the press. Momentary “blackouts” of online media affect the flow of information, the legitimacy of the company and its journalists, and also cause adverse economics effects for the media companies which base their income in online advertising. “The attacks almost always occur as a result of some publication, that is to say they are more reactive than proactive,” Guerra said of the Latin American case. “The freedom of the press is vulnerable not only when a journalist is killed or a broadcaster is exploited.” In fact, in the 2014 Annual Report of the Special Rapporteur for Freedom of Expression of the Inter-American Commission on Human Rights (CIDH), at least four cases of these attacks on media in Mexico were reported. “With the changes in technology and ways of doing journalism, cyber attacks will become more frequent because they attack the legitimacy of the journalist, and also affect the publication of news. Therefore, all attacks and threats should be condemned with the same intensity,” Guerra added. In addition to clear legislation, the region also lacks information on how and where these attacks occur, as well as statistics on their targets and consequences. In 2000, one of the companies specializing in digital security solutions, Arbor Networks, joined Google Ideas (an Internet research and conflict solution implementation think tank) to create a map that tracks digital attacks happening around the world, in real time. The aim was to create a tool for identifying these anonymous attacks: What is the origin of the attack, its target, and the duration and type of attack? It also aimed to analyze trends. Looking at the map, you can see that the peak of the cyber attacks in Latin America happened in December 2014. “It’s very interesting to see that most of the attacks are concentrated in a few countries in the region and that they are the result of specific moments in those countries,” Guerra said. “In the case of Guatemala, a reason for the attacks may be that at that time people were discussing the results of the International Commission Against Impunity in Guatemala. In the case of Peru, the second round of December 2014 regional elections may have influenced events.” What is a DDoS attack? At the technical level, a DDoS attack occurs when millions of simultaneous requests are sent to a single server in order to make it collapse. It is a targeted, deliberate action using hundreds of connected computers to make a simultaneous attack.? In an interview with the Knight Center, Hector Jara, founder and director of Enfinity, a Panamanian cybersecurity and information safety management company, explained the concept with an analogy. “Imagine a highway where a few cars circulating at high speeds and the traffic is fluid. As you add more and more cars, the driving pace slows and traffic is less fluid. If we continue to add cars, you will reach a point where the highway is saturated and cannot meet the demand, and the cars will be stopped. The same thing happens with connections to a website. The number of connections that it can respond to is limited, and if it makes more and more connection, at some point it will be saturated. The more capacity the organization has, this is more difficult to achieve – we think of Google Facebook, among others – but the limit always exists.” Jara also explained how criminal organizations use other types of attacks – for example phishing – through which they infect computers of ordinary users. “These infected computers are known as zombies , and can be controlled and used by these organizations to launch other attacks, such as DDoS. In fact these organizations assemble networks of zombie computers (known as botnets ) that they then ‘rent’ for non-sanctioned purposes”. The cybersecurity expert said that in addition to political purposes and censorship attacks, other attacks are related to digital protest. For example, the term Hacktivism is a new form of protest increasingly being used. One of the latest examples of the use of technology as a means of social protest was during the removal of former President Fernando Lugo of Paraguay when attacks on public bodies were made and one of them closed access to the official website of the Presidency. Asked about possible actions against these attacks, Jara explained that “while we can design a communications architecture in a way that can protect against these attacks – for example there are technological tools such as Web Application Firewalls and services such as CloudFlare , which can mitigate the impact and in some cases completely limit it – by the nature of the attack, if those interested in launching the attack had enough resources and time, it is likely that the would force a site out of operation.” While in the United States DDoS attacks are considered crimes and are punishable under the penal code, this has not been shown to combat the situation. The question is what can legislation achieve regarding this issue. Experts agree that international cooperation is key to fighting cybercrime. In 2014, Mexico hosted the “Workshop on legislation on cybercrime in Latin America”, organized to support Latin American countries in developing legislation on cyber crime, in accordance with international standards proposed in the “Budapest Convention “. During the meeting, possible reforms to criminal law of the participating countries and constitutional reforms in telecommunications were debated. While Argentina, Chile, Colombia, Costa Rica, Mexico, Paraguay and Peru have expressed their interest in joining the treaty, Dominican Republic and Panama have already completed this process. “Most regional legislation concerning information security have been poorly, and in many cases have been motivated by local public security crisis,” said Guerra of Privaterra. “So, from the start, these are deficient laws that in many cases secretly seek to impact civil society through censorship and criminalization of social networking activity.” Guerra also said it is not possible to speak of general solutions in Latin America, but that “each region has its own dynamics, and accordingly, legislation should create or strengthen legal counter methods to give tools for protection to civil society. These tools should be autonomous and independent of government.” Meanwhile, Jara noted that while regulations should establish a legal framework that protects personal information and data, in the case of journalists, these professionals should take measures to protect such data. “Because of the work, they may be a target of criminal organizations and sometimes governments. If they also have blogs or personal pages, they should ensure the safety of them, as a vulnerable site also becomes the focus of attack, ” Jara said.

DDoS attack on DigitalOcean for Alleged on-campus rape

Denial of service attack staged against DigitalOcean, which hosts video stemming from Columbia University student’s protest about alleged on-campus rape The service provider hosting the latest visual art project by Columbia University graduate Emma Sulkowicz has confirmed the site was temporarily disabled by a sophisticated cyberattack after the film which she warns “may resemble rape” was published online last week. Sulkowicz graduated from Columbia in May after completing a year-long performance art project in which she carried a dorm room mattress everywhere she went on campus to protest about the school’s refusal to expel the man she accuses of raping her. The website hosting Sulkowicz’s video, titled Ceci N’est Pas Un Viol, French for This Is Not a Rape, was hit by a denial of service (DoS) attack, in which hackers attempt to force a targeted website offline, according to Keith Anderson, platform support lead at DigitalOcean, where Sulkowicz site is hosted. “We can confirm that there was a denial of service attack on Thursday,” Anderson said. “On Friday there was also a spike in outbound bandwidth coming from the website, likely due to a sudden increase in traffic and unrelated to the attack, so we worked with their web team to resolve the issue and their site is back up and running.” Sulkowicz told the Guardian that she has no doubt the cyberattack was deliberate. But she said she was prepared for it. Her accusation that a classmate raped her was met with a backlash, counter-accusations and trolling. In the video Sulkowicz and an unidentified man engage in a sexual encounter that appears to begin consensually before turning violent. During the act the man slaps her multiple times, ignores her protests and and continues to have violent sex. Sulkowicz and her mattress became a powerful symbol of the movement to reform campus responses to sexual violence after vowing to carry it around campus as her visual arts senior thesis. The video is the artist’s first major work since the conclusion in May of her performance art piece Mattress Performance: Carry That Weight. Sulkowicz accuses Paul Nungesser of raping her in August 2012 at the start of their sophomore year. Columbia investigated the incident and later cleared Nungesser of all responsibility during a campus tribunal. Nungesser has maintained that the encounter was consensual and has since filed a lawsuit against the university, its president and an art professor alleging that the school enabled a harassment campaign. Sulkowicz called the experience of making the video “terrifying” and “traumatizing” but said she was determined to make it because she believed so strongly in its importance. “I was in a very scared, emotional state for days,” Sulkowicz told the Guardian. Sulkowicz said she conceptualized the project in December and pitched it to artist Ted Lawson, whom she met through performance artist Marina Abramovi?. While collaborating on a separate project with Lawson, Sulkowicz said she suggested the video and asked him to direct it. In an interview with ArtNet News, Lawson said: “It was a super risky piece and I thought very courageous, so of course I agreed.” They filmed the video in one of the university’s dorm rooms over spring break, Sulkowicz said. The male actor remains anonymous and his face is blurred in the video. The timestamps on the videos are blurred. Though Sulkowicz said her friends and family have been very supportive in private, she said it can hurt when they don’t support her publicly online. “The trolls don’t upset me as much as when my friends don’t support it,” she said. “I expect the trolls but to see my friends not support it [vocally] is upsetting.” Sulkowicz has said the encounter with Nungesser began consensually but then turned violent. The video echeos her account of that night in August 2012. Though Sulkowicz says it is not a re-enactment, she does appear in the video. Introductory text for the video contains a trigger warning: “The following text contains allusions to rape.” In complementary text published with the video Sulkowicz writes: “Ceci N’est Pas Un Viol is not about one night in August, 2012. It’s about your decisions, starting now. It’s only a re-enactment if you disregard my words. It’s about you, not him.” She characterized reaction to her latest piece as “somber”. Asked what that meant, she said: “With this piece there’s really nothing to rally behind. It’s really more of a quiet, reflective type of support.” Sulkowicz said she was working on a new art piece that she expects to publish soon. She would not give any hints about the theme of the new project. “It’s a different piece,” she said, “but I have only one body and one history to work with.” Source: http://www.theguardian.com/us-news/2015/jun/09/emma-sulkowiczs-this-is-not-a-site-taken-down-by-cyberattack

China Overtakes US as Top Source of Distributed Denial of Service Attacks

More Distributed Denial of Service (DDoS) attacks originated in China than in any other country, followed by Germany and the United States, according to the Q1 2015 State of the Internet – Security Report by cloud services provider Akamai. China is responsible for 23.45% of the world’s DDoS attacks , malicious attempts to make servers unavailable to users by interrupting the services of a host connected to the Internet, while 17.39% came from Germany and 12.18% from the US. The number of Chinese DDoS has risen 66% in attack source IPs compared with the US, although researchers say it could be attributed to the increase in redirected traffic from Asia. The United States was the origin of 32% of DDoS attacks in Q4 2014, with China at 18%. The percentage drop does not indicate a decline in attacks from these countries, but rather a change in proportions as the number of total DDoS attacks worldwide soars. DDoS attacks have increased 117% quarter-over-quarter and 35% quarter-on-quarter. The quarter set a record for the number of DDoS attacks observed over the Prolexic network, while the attack duration is now 43% longer than in Q1 2014, according to the report. The US was the top source country of attacking IPs, at 52%, followed by China at 11% and Brazil at 6%, among source countries for web application attacks. US-based websites were the most targeted for web application attacks in Q1 2015, receiving 82% of attacks , while no other country was targeted for more than 2% of attacks. Retail, media/entertainment and hotel/travel were the most targeted industries for web application attacks in Q1 2015. This stems from previous attacks on the financial service sector, which hardened its security policy significantly. Meanwhile, retail and media attacks and breaches of 2014 signaled that these industries were softer targets, leading attackers to probe them for vulnerabilities.

Google Chrome extension turned users into a DDoS botnet

Hola turned users’ PCs into a botnet, without their consent. Hola, an online service used for watching blocked videos and TV shows from websites outside of your country, has turned users’ PCs into a botnet without their consent. According to The Verge ,   the free-to-use software – which is available as a Chrome plugin – was secretly selling users’ “idle resources” (bandwidth), allowing anyone to buy traffic and redirect it to any site as a denial-of-service attack. This means that Hola users could have been part of a botnet attack. The reports came to light after sites were affected by the denial-of-service attacks from Hola’s network. Hola’s founder Ofer Vilenski said the site has “always made it clear” how its business model works. However, according to The Verge Hola’s users seem to have been almost universally unaware that their bandwidth was being sold off.

How Visual Basic Broke Modern Python: Welcome to the World of High Orbit Ion Cannon

In 2012, Anonymous introduced HOIC (high orbit ion cannon) as a replacement to LOIC (low orbit ion cannon). Unlike its predecessors, that were built upon C#, and later java. This new DDoS player was built upon the unsuspecting language of Visual Basic. Taught in high school classrooms, Visual Basic was largely seen by the programming community as a means for kids and young programmers to get their feet wet in the experience of programming. Considered by many programmers as grossly inefficient and a memory hog; Visual Basic was an unsuspected carrier for what would become one of the most powerful means of DDoS. One of the popular notions of HOIC has been its ability to randomize variables such as: user agent, referrer and URI, during an attack. In the same manner, an attack tool known as HULK (developed by: Barry Shteiman, 2012), written in Python, was developed in recent history. Within a controlled environment we tested these DDoS tools to judge their effectiveness and total output. In controlled trials the DDoS output of LOIC (Visual Basic on Windows) outperforms the DDoS output HULK (Python on Linux) by +40%. Figure 1: HOIC Test in Stable Windows Environment Figure 2: HULK Test While many of us in the Internet security industry ridicule and downplay the “kiddie hacker;” it is clear that it sometimes only takes a kiddie to build an empire. Lessons in open source economics teach us that in an open access environment, it takes only a small few to bring about radical change and innovation. Today HOIC has become one of the primary tools of groups such as anonymous. From this lesson, we can expect that challenges and sudden changes, will not come from those paid hundreds of thousands a year; but from those small few kiddies, whom are politically motivated and are paid nothing.

DDoS Attack Update: Idaho Teen Faces Felony Charges After Unleashing a DDoS Attack on School District

In May 15, KTVB reported that a student recently launched a cyber-attack on one of Idaho’s largest school districts. The attack, which was identified as a Distributed Denial of Service (DDoS), practically rendered the entire district’s internet unable to function. The attack was so powerful that it caused internet problems for the affected school district for weeks without ceasing. A lot of Idaho students working on achievement tests lost all their data, and some even had to retake the exam multiple times because of the gravity of the attack. Even the administrative network itself, which, unfortunately, included the teachers’ payroll data was compromised. A DDoS attack occurs when multiple systems compromised by a Trojan are used by a host, or in this case, a channel, to target a single host simultaneously causing a denial of service. In simple terms, the attack floods a single network with immeasurable internet traffic until it simply stops dead on its tracks. Most of these attacks exploit problems within the victim computer’s TCP/IP system. Because a DDoS attack comes from hundreds, possibly even thousands of sources at once, it is practically impossible for any program on earth to track down the actual source of the problem. To make matters worse, a DDoS attack makes it impossible to identify actual, legitimate traffic, because everything gets lost in a haze of incoming data. Despite the overwhelming odds, the authorities managed to trace the attacker’s IP address back to the high school student. Today, he faces the possibility of expulsion, as well as 180 days in a juvenile detention center. Authorities say that he might even be facing serious federal charges. Moreover, the culprit’s parents will also be expected to pay any losses that the school district has incurred due to the attacks. A representative for the West Ada School District said that there might be other students within the area who know how to carry out this cyber-attack. Nevertheless, the spokesperson reassured everyone that further attacks will be dealt with more readily. The district also sent a message to parents of students enrolled in their schools, urging them to help keep their children from committing cyber attacks.
