“It is impossible to say with certainty that the hacker attack on the largest pipeline operator in the United States, the Colonial Pipeline company, was carried out from Russia, the participation of hackers from the CIA is not excluded,” RIA Novosti quoted Kaspersky as saying.

In addition, according to Kaspersky, according to a 2017 WikiLeaks investigation, the US Central Intelligence Agency has a UMBRAGE unit that mimics various types of global hacker groups.

She clarified that, as a rule, if "a cyber attacker does not want to leave some information about himself, then it is almost impossible to establish his origin for certain."

Earlier, the American Infrastructure and Cybersecurity Agency (CISA) received from Colonial Pipeline new information about the details of a hacker attack on it.
