Summary
Historically, macOS was thought to be less vulnerable to malware than Windows, partly due to its smaller market share and built-in security features that forced malware developers to use unconventional methods. However, this perception has shifted over time. Mainstream malware is now increasingly targeting macOS, with infostealers being a notable example. Our data shows that stealers make up over 50% of macOS detections in the past six months, with Atomic macOS Stealer (AMOS) being one of the most prevalent families.
