Just as legitimate software developers have adjusted to Apple's ARM transition, so too have malware distributors.

Security researchers have identified malware customized to run on Apple's new M1 processors in the MacBook Pro, MacBook Air, and Mac Mini computers.

Mac security researcher Patrick Wardle reported a Safari adware extension originally authored to run on Intel x86 chips has been redeveloped to target M1s.

The GoSearch22 sample Wardle found masquerades as a legitimate Safari browser extension, then collects user data and posts illicit ads, including some linking to other malicious sites.

Researchers with security firm Red Canary said they also are probing a strain of native M1 malware distinct from Wardle's discovery, adding that there is often a lag in detection rates as antivirus and other monitoring tools gather digital signatures for new types of malware.
