A wave of new MacOS malware over the past month includes a zero-day exploit and other attack code.
A wave of malware targeting MacOS over the past month has raised the profile of the operating system once advertised as much safer than Windows. The newest attack code for the Mac includes three pieces of malware found in June — a zero-day exploit, a package that includes sophisticated anti-detection and obfuscation routines, and a family of malware that uses the Safari browser as an attack surface.
The zero-day exploit, dubbed OSX/Linker by researchers at Intego who discovered it, takes advantage of a vulnerability in MacOS Gatekeeper — the MacOS function that enforces code-signing and has the ability to limit program execution to properly sign code from trusted publishers.
