Hackers Using Trojanized macOS Apps to Deploy Evasive Cryptocurrency Mining Malware

Trojanized versions of genuine applications are becoming made use of to deploy evasive cryptocurrency mining malware on macOS programs.

Jamf Risk Labs, which manufactured the discovery, said the XMRig coin miner was executed as Ultimate Minimize Pro, a video enhancing software program from Apple, which contained an unauthorized modification.

“This malware will make use of the Invisible Internet Task (i2p) […] to down load destructive parts and send out mined forex to the attacker’s wallet,” Jamf scientists Matt Benyo, Ferdous Saljooki, and Jaron Bradley stated in a report shared with The Hacker News.
