Operation Medusa: FBI Tool Instructs Turla Group’s Malware to Self-Destruct
Federal district attorneys said Tuesday that they had actually interrupted a Russian intelligence cyberespionage operation by targeting malware utilized by Kremlin hackers to take classified and delicate details. The disturbance took place through the remote implementation of an FBI tool called Perseus that released commands triggering the malware, referred to as Snake, to overwrite itself.

A U.S. District Court judge released a search and seizure order Thursday licensing the FBI to utilize the tool to target 8 U.S. systems contaminated by Snake as part of an effort the Department of Justice called “Medusa.” In Greek folklore, Perseus killed the Gorgon Medusa after being deceived into the mission by his prospective father-in-law.
The FBI in a sworn declaration connected the malware to a unit of Russia’s Federal Security Service likewise referred to as Turla, a group likewise called “Krypton,” “Venomous Bear” and “Waterbug” by security scientists.
Turla frequently targets both federal government companies and the economic sector, and is understood to have actually taken files from numerous systems worldwide. Its victims consist of NATO federal governments, reporters and others of interest to Moscow.
Michael J. Driscoll, assistant director in charge of the FBI’s New York field workplace, explained Snake as the Russian federal government’s “primary cyberespionage tool.”
Most Snake infections utilize the host computer system as a routing point in a peer-to-peer network utilized by Russian state hackers, the FBI said, “to make it harder for jeopardized victims to recognize and obstruct suspicious connections to Snake-jeopardized endpoints, to name a few factors.” Although Snake’s code is the basis for a series of extremely respected malware consisting of the Carbon backdoor, Kremlin hackers have actually not released Snake commonly in a quote to reduce the possibility of detection, the FBI likewise said.
Snake gains perseverance on contaminated systems by packing a kernel driver and utilizing a keylogger that consistently reports back to FSB hackers, says a joint cybersecurity advisory launched Tuesday by the Five Eyes intelligence alliance, consisted of Australia, Canada, New Zealand, United Kingdom and United States.
“Many systems in this P2P network act as relay nodes which path camouflaged functional traffic to and from Snake implants on the FSB’s ultimate targets,” the advisory says. “Snake’s custom-made interactions procedures use file encryption and fragmentation for privacy and are created to hinder detection and collection efforts.”
Snake’s kernel element takes a look at incoming web traffic to see if it consists of a unique authentication code. When it does, it forwards the packages onward to another Snake node. That approach of interception permits the malware to interact without detection by normal invasion detection security apps or firewall softwares.
Versions of Snake contaminate systems running Windows, along with Linux and MacOS, and are created to enable assaulters to press modules with extra harmful abilities onto contaminated endpoints. Even when victims find the malware, it has actually traditionally been difficult to get rid of.
Nevertheless, the DOJ said Snake’s designers made some mistakes that it had the ability to make use of to discover methods to interrupt the malware and its associated facilities.
Moonlit Maze, Agent.biz
Even if Snake operations are completely interrupted, the group implicated of wielding the Turla toolset has actually already protected its location in cybersecurity history, having actually been connected to among the very first recognized episodes of cyberespionage in the 1990s, called Moonlit Maze by the FBI. Later, Turla was implicated of building the harmful Agent.btz worm found in 2008, which effectively took military tricks and assisted birth U.S. Cyber Command.
“Turla is a Russian cyberespionage star and among the oldest invasion groups we track, existing in some form as early as the 1990s when Kevin Mandia was reacting to their invasions into federal government and the defense market,” said John Hultquist, head of intelligence analysis at occurrence action company Mandiant, which becomes part of Google.
Western intelligence authorities state Snake started advancement as “Uroburos” in late 2003 and debuted in early 2004. They state it seems connected to a particular center in Ryazan, Russia, backed by everyday operations that range from about 7 a.m. to 8 p.m. regional time.
Turla pursues “the traditional targets of espionage – federal government, military and the defense sector – and their activity is identified by a dependably peaceful attack on these targets that seldom draws attention,” said Hultquist, including that the group has actually ended up being understood for its continuing development.
Iranian Mischief
One of Turla’s more ingenious supposed efforts included pirating attack tools and command-and-control servers utilized by an Iranian nation-state group called OilRig – aka APT34, Crambus or Helix Kitten.
Russian-speaking assaulters’ usage of the suborned Iranian facilities triggered private-sector security scientists to very first quality the attacks to Iran. Later, the National Security Agency and U.K. National Cyber Security Center released a joint alert stating that Russia had lagged a variety of appearing OilRig projects (see: Turla Teardown: Why Attribute Nation-State Attacks?).
Turla’s activities were detailed in a secret 2011 discussion by Canada’s Communications Security Establishment that was dripped by ex-NSA professional Edward Snowden in 2013.
The discussion explains the activities and facilities of Turla, which has the codename MAKERSMARK, as “created by geniuses, carried out by idiots.” It says Turla members seemed utilizing the attack facilities for personal surfing which the group’s advancement environment had actually been “contaminated by crimeware.”
