An “ongoing” cyberattack against the Japanese technology giant Olympus was caused by a Russian ransomware group sanctioned by the U.S. government, according to two people with knowledge of the incident.

A new malware variant known as Macaw was used in the attack that began on October 10, which encrypted Olympus’ systems in the U.S., Canada and Latin America. Macaw is a variant of the WastedLocker malware, both of which were created by Evil Corp., a Russia-based crime group that was subject to U.S. Treasury sanctions in 2019.
