Researchers have discovered another malware that runs natively on the new one Apple M1 Mac Silicon, and this one seems much more sinister.
“Our investigation almost immediately found that whatever it was, this malware was not behaving as we would expect from the common adware that is so often targeted macOS systems“Noted Tony Lambert, an intelligence analyst at security firm Red Canary post on the threat.
Lambert, known as Silver Sparrow, says the malware has infected around 30,000 MacOS computers in over 150 countries.
Collecting data on the malware from other security researchers Malwarebytes and VMware Carbon Black, Lambert soon realized that it was a novel type of malware.
In his analysis, he finds that the malware calls a command and control server on the infected computer every hour to look for further instructions. Until now, the researchers have failed to notice that the malware is downloading malicious payloads, adding to the mystery of the malware’s real intent.
“Although we haven’t seen Silver Sparrow deliver additional malicious payload, the advanced compatibility with M1 chips, global reach, relatively high infection rate, and operational readiness suggest that Silver Sparrow poses a reasonably serious threat to be found in is in a unique position to have potentially effective payload impacts in the shortest possible time, ”explains Lambert.
