Hackers using Shellshock to spread Kaiten Mac OS DDoS malware

Hackers are exploiting the Shellshock bug to infect numerous systems, including Apple Mac OS X, with a distributed denial-of-service (DDoS) malware known as Kaiten. Security researchers from Trend Micro reported uncovering the campaign in a blog post, warning that it has the potential to inflict devastating DDoS attacks. “We found that one of the payloads of Bash vulnerabilities, which we detect as TROJ_BASHKAI.SM, downloaded the source code of Kaiten malware, which is used to carry out denial-of-service attacks,” read the post. “Kaiten is old IRC-controlled DDoS malware and, as such, there is a possibility that the attackers employed Shellshock to revive its old activities like DDoS attacks to target organisations.” Discovered earlier in September, Shellshock is a critical vulnerability in the Bash code used by Unix and Unix-like systems. Trend Micro listed the new attack’s ability to infect Mac OS systems as being particularly troubling, highlighting it as evidence that hackers are using Shellshock to expand the victim-base of their campaigns. “Typically, systems infected with Shellshock payloads become a part of their botnet, and therefore can be used to launch DDoS attacks. In addition, the emergence of a downloaded file that targets Mac OS clearly shows that attackers are broadening their target platform,” the security firm said. Trend Micro added that the threat is doubly dangerous as Apple had mistakenly told its users that most should be safe by default. “Users who configured to enable the Advanced Unix Services are still affected by this vulnerability,” read the post. “The Advanced Unix services enables remote access via Secure Shell which offers ease of access to system or network administrators in managing their servers. This service is most likely enabled for machines used as servers such as web servers, which are the common targets Shellshock attacks.” Apple released security patches to plug Shellshock for its OS X Maverick, Lion and Mountain Lion operating systems in September. The Trend Micro researchers added that IT managers should be on guard for the attack as it has advanced detection dodging powers. “When it connects to http://www[dot]computer-services[dot]name/b[dot]c, it downloads the Kaiten source code, which is then compiled using the common gcc compiler. This means that once connected to the URL, it won’t immediately download an executable file,” explained the researchers. “This routine could also be viewed as an evasion technique as some network security systems filter out non-executable files from scanning, due to network performance concerns. Systems configured this way may skip the scanning of the source code because it’s basically a text file.” The Kaiten attack is one of many recently discovered campaigns using Shellshock. Researchers from FireEye caught hackers exploiting the Shellshock Bash vulnerability to infect enterprise Network Attached Storage systems with malware at the end of September.

The History of DDoS Attacks as a Tool of Protest

Although the web is only a quarter of a century old, it already has a rich history as a platform for worldwide protest. One common tool used by online activists is the distributed denial of service attack, or DDoS: a technologically crude tactic that involves sending so many requests to a target website that it crashes. In recent years, politically motivated DDoS attacks have been launched on the websites of financial giants and local government departments. This year, websites affiliated with the football World Cup were brought down in protest against FIFA. “DDoS has been around as an activist tactic probably since the early 90s,” Molly Sauter, a research affiliate at Harvard University’s Berkman Center for Internet and Society and doctoral student at McGill University, told me. Sauter is the author of the upcoming book The Coming Swarm: DDoS Actions, Hacktivism and Civil Disobedience , which details the history of the DDoS attack from an obscure, insular activity carried out by artists and intellectuals to a hallmark of 21 st century protest. The earliest example of a DDoS attack that Sauter found in her research was implemented by the Strano Network, an Italian collective that launched an attack in 1995 to protest against the French government’s nuclear policy. Back then, DDoS attacks were laborious, manual affairs, requiring participants to constantly remain at their computer. And because having an internet connection was relatively expensive, they couldn’t last for long. The attack in this case only endured for about an hour. The next major milestone was the use of DDoS by the Electronic Disturbance Theater (EDT). Originating in the 90s, and attracting the attention of the media by the end of the decade, the hacktivist group described DDoS as akin to a “virtual sit-in.” One thing that separated them from their predecessors was their use of tools developed in-house, which allowed anyone outside of the organisation to join in. Their kit, called FloodNet, directed a user’s traffic to a target predetermined by the EDT, which included the websites of politicians and the White House. Those wishing to join the “sit-in” simply selected their target from a drop down menu, clicked attack, and relaxed while FloodNet automatically bombarded the offending server. The well-known hacker collective Anonymous took this idea of crowd-sourced activism further, and popularised the idea of voluntary botnets. Often used by criminals, a botnet is a large number of systems, all linked together, which give whoever is in charge of them a whole lot of processing power to wield. DDoS is incredibly simplistic, at a purely technological level. By using the hacker-designed software Low Orbit Ion Cannon, and its subsequent upgrades, participants could connect their computer to a vast network and have it donate resources to DDoS attacks. And that pretty much brings us up to today. “DDoS is incredibly simplistic, at a purely technological level,” Sauter said. “While there might be individual innovations in ways of masking or multiplying traffic, it’s not actually going to get much more advanced than that.” But it’s not just the technical details of DDoS that have mutated over the years. The scale of attacks using the device has developed, too. “Groups have become better at attracting, acknowledging and manipulating media coverage in order to attract more participants,” Sauter explained. While earlier groups just did their own thing, Anonymous managed to engage those outside of their immediate cohort more readily. With their iconic imagery, popular Twitter accounts and evocative videos, the media had a lot of material to work with. The press lacked any sort of official spokesperson of Anonymous to talk to—“So they just tended to reproduce these artifacts in media coverage, which did the work of recruitment for Anonymous,” Sauter observed. “Anonymous didn’t have to do a lot of ‘active’ outreach. That was being done for them.” What actually constitutes a ‘successful’ DDoS attack has also changed. “In the 90s, you could sit in front of your computer with your friends, go to whitehouse.gov, click refresh a bunch of times, and you had a significant chance of the website crashing,” said Sauter. An industry has since emerged to offer protection from DDoS attacks, so crashing a major service today is rarer, though still possible with some serious fire-power. But there’s another way to measure the success of DDoS actions than just website down time. Sauter explained that, when it comes to activism in general, “The logic of change is that you have an action, you get covered in the press, then politicians and the public react to the press coverage, not so much the action itself.” This overall impact is perhaps more important than how long a specific website is technically inaccessible. As Sauter said, “The question of what success means is fairly up in the air.” Some argue that DDoS as a protest tool should be formally recognised as political speech, and enjoy the same free-speech protections as street marches, for example. Jay Leiderman, a criminal defense lawyer, has argued that DDoS is a first amendment issue in defence of the “PayPal 14,” a group of WikiLeaks supporters involved in a DDoS attack against the e-commerce business. Attorney Stanley Cohen, who represented one of the accused, described the act as an “electronic sit in,” and members of Anonymous also created a petition, pushing for politically motivated DDoS to be legalised. CIVIL DISOBEDIENCE AND OTHER TYPES OF ORGANISED LAW BREAKING ONLINE ARE STILL CONSIDERED VERY MUCH FRINGE ACTIVITIES. But DDoS can of course also be used for much less sympathetic purposes. “The biggest problem that activist DDoS faces in terms of its fight for legitimacy is criminal DDoS,” said Sauter. “DDoS is a very popular tactic in terms of harassment, extortion and other criminality.” For example, botnets for DDoSing purposes are reportedly already being created to exploit the Shell Shock bug, a recently revealed weakness in Linux and Unix operating systems. Furthermore, Sauter suggested that online activism in general still isn’t really accepted because it remains an alien concept to many people. “Civil disobedience and other types of organised law breaking online are still considered very much fringe activities because there isn’t an understanding that civil disobedience is something that you can do on the internet,” Sauter said. “That I hope is something that will change, but it will take a legal challenge.” But Sauter feels that political DDoS will continue to gain popularity when it comes to activism, and that it might even have something more to give. Whether it’s the Electronic Disturbance Theater protesting against neoliberalism, or Anonymous rising up to fight what they see as injustices, DDoS actions do not exist in a vacuum. Today, politically motivated DDoS is often part of a broader activist culture in the information age. Sauter suggested it could therefore introduce activists to other ideas, “such as information exfiltration, and leaking, and the construction of alternative infrastructures to replace the corporate-dominated and government-surveilled that are currently the main ways of socialising and communicating online.” In short, DDoS attacks in activist circles can be about more than just crashing a few servers.

Telegram under 150Gbps DDoS attack

Cross platform messaging app Telegram has been a target of massive distributed denial of service (DDoS) attacks for two days in a row over the weekend with the largest in tune of 150Gbps. The DDoS attacks started on Saturday – September 27 – and according to Telegram the scale of the attack was in tune of tens of Gbps. “A DDoS attack on Telegram in progress, tens of Gigabitsec. Users in some countries may have connection issues. We’re working on it, folks!” tweeted Telegram. Prior to the official confirmation, users started complaining of connectivity issues as well as not being able to send messages successfully. These complaints were picked up by Telegram administrators and upon investigation they zeroed it down to DDoS attack. Telegram soon managed to recover from the attack, but DDoS perpetrators launched another massive attack and this time in tune of of 150Gbps. “Detecting a 150+ Gbit/s DDoS now, an attack three times as large as yesterday’s.” tweeted Telegram. Users are still complaining about connectivity issues and there has been no confirmation from Telegram on whether they have been able to resolve the issue or not.
