Days after the first malware targeting Apple M1 chips was discovered in the wild, researchers have disclosed yet another previously undetected piece of malicious software that was found in about 30000 Macs running Intel x86_64 and the iPhone maker’s M1 processors.

However, the ultimate goal of the operation remains something of a conundrum, what with the lack of a next-stage or final payload leaving researchers unsure of its distribution timeline and whether the threat is just under active development.

Calling the malware “Silver Sparrow,” cybersecurity firm Red Canary said it identified two different versions of the malware — one compiled only for Intel x86_64 and uploaded to VirusTotal on August 31, 2020 (version 1), and a second variant submitted to the database on January 22 that’s compatible with both Intel x86_64 and M1 ARM64 architectures (version 2).
