(Reuters) – FBI Director Christopher Wray told the Wall Street Journal that the agency is investigating about 100 different types of ransomware, many of which trace back to actors in Russia.
In an interview published on Friday, Director Wray pointed out Russia, which houses many of the known users of ransomware.
Each of the 100 different malicious software variants is responsible for several ransomware attacks in the United States, Director Wray told the newspaper.
The Kremlin on Friday said the FBI director's remark that Russia was a haven for hackers was "emotional", the RIA reported.
Director Wray's comments come days after a cyberattack disrupted much of the meat packer JBS SA's North American and Australian operations. The White House linked the attack to a Russia-based group.
Last month, the largest U.S. gas pipeline, the Colonial Pipeline, was hit by a ransomware cyberattack that paralyzed supplies for several days in the southeastern United States. The FBI attributed the cyber attack to a group believed to be based in Russia or Eastern Europe.
The US Department of Justice raises investigations into ransomware attacks to a similar priority as terrorism, a senior department official told Reuters on Thursday. [1
