Over the previous yr, we’ve seen them conduct a number of provide chain assaults, poison respectable software program, and develop and deploy customized malware onto MacOS methods,” stated Mandiant’s CTO Charles Carmakal. “They finally need to compromise firms with cryptocurrency and so they’ve discovered artistic paths to get there. However additionally they make errors which have helped us attribute a number of intrusions to them.”

SentinelOne and CrowdStrike additionally confirmed North Korea was behind the JumpCloud intrusion.
