New MacOS-based info stealer

Security firm Uptycs has identified new info-stealing malware named MacStealer that’s targeting Mac users. The malware developer is selling premade builds of the malware for $100, allowing purchasers to use the malware in their email campaigns.

This macOS malware can run on macOS Catalina and up to the latest version of Apple's OS, Ventura. It’s designed to steal credentials stored in the iCloud KeyChain, web browsers, and cryptocurrency wallets and is being distributed as unsigned DMG files via phishing emails.

Take aways:

  • Keep your Mac systems up-to-date with the latest updates and patches

  • Only permit the installation of files from trusted sources that allow ‘App Store’ or ‘App store and identified developers.’
