Sentinel Labs researchers have identified an updated version of the cryptominer OSAMiner that targets the macOS operating system to mine for monero.
The latest iteration uses new techniques to help prevent detection by security tools, the researchers report.
OSAMiner, which has been active since 2015, has been distributed through hacked video games, such as League of Legends, as well as compromised versions of software packages, including Microsoft Office for macOS, Sentinel Labs says.
The malware now uses multiple versions of AppleScript - a scripting language used in macOS devices - to support obfuscation. OSAMiner s operators released the latest version of the cryptominer in 2020, but researchers only recently discovered the enhancements, according to the researchers report.
