An ex-Canadian government IT worker has admitted to being a high-level hacker with a Russian cyber-crime group.
Sebastien Vachon-Desjardins, from Quebec, Canada, has agreed to plead guilty in a Florida court.
The 34-year-old was affiliated to the NetWalker ransomware crew, which has attacked companies, municipalities, hospitals, schools and universities.
When he was arrested, police discovered he was in possession of $27m (£22.2m) in Bitcoin.
