The FBI today confirmed that the cyberattack that forced Colonial Pipeline to take its network offline over the weekend is due to ransomware known as DarkSide.
"The FBI confirms that the DarkSide ransomware is responsible for the compromise of the Colonial Pipeline networks," the agency says. "We continue to work with the company and our government partners on the investigation."
During a Monday White House press briefing, Anne Neuberger, Deputy National Security Advisor for Cyber and Emerging Technology, said the FBI has been investigating the DarkSide variant since October 2020, and has determined that it's a ransomware-as-a-service attack, meaning "criminal affiliates conduct attacks and then share the proceeds with ransomware developers," she said.
Though news reports have tied DarkSide to Russian operatives, President Biden said Monday that "so far, there's no evidence...from our intelligence people that Russia is involved, although there is evidence that the actors [behind the ransomware are] in Russia, [so] they have some responsibility to deal with this."
Neuberger also declined to place the blame on any one party. "At this time we assess that DarkSide is a criminal actor," she said, but the US intelligence community is still investigating whether a particular nation-state is responsible.
Asked if Colonial had paid a ransom, Neuberger said "Colonial is a private company and we'll defer to them."
The federal government is currently looking at what type of advice to offer companies when they're hit by ransomware, she added. When a reporter noted that the FBI has long advised ransomware victims not to pay ransoms, Neuberger said "we recognize...that companies are often in a difficult position if their data is encrypted and they do not have backups and cannot recover the data.
"We need to look thoughtfully at this area, including with our international partners, to determine what we do, in addition to actively disrupting infrastructure and holding perpetrators [responsible] to ensure we're not encouraging the rise of ransomware," she added.
