Red Canary security researchers have discovered a mysterious and sophisticated macOS malware said to be affecting 30,000 Macs around the world. It is currently being referred to as Silver Sparrow and has a variant specifically optimized for Apple's M1-powered MacBook units launched last year.
The report reveals that the macOS malware on affected units checks for a control server once every hour. This is the only thing known about what the malware does. The team is yet to discover any kind of payload and as a result its ultimate goal. It is speculated that there is an unknown condition that needs to be met for the malware to get active and start its actual job.
One of the interesting things about Silver Sparrow is that it features an auto-destruction mechanism. It means if the hackers behind the malware want no one to have anything tracing back to them, they can simply make it destroy itself. This is something that is not a common thing to happen with malware.
