Security researchers at Malwarebytes and red Canary discovered a mysterious piece of malware hiding on nearly 30,000 Macs. They’re calling it silver Sparrow.
The first piece of malware discovered in the wild targeting Apple silicon. Red Canary’s blog post goes into more detail, including how new Apple’s M1 computers are.
Silver Sparrow was not able to cover its tracks before being outed. There’s no indication it was used to do any damage. Apple has already revoked the binaries.
Silver Sparrow delivers a potentially impactful payload at a moment’s notice. We wanted to share everything we know with the broader InfoSec community sooner rather than later.
