Nearly 40,000 Apple Macs infected by mysterious malware

Mysterious malware - that has not yet engaged in malicious activity - has infected nearly 40,000 Mac devices, ABC News reports, citging the cybersecurity firm Red Canary, which first detected the threat.

The malware, dubbed by Red Canary as "Silver Sparrow," is baffling researchers because of its elusive motives.

 "Most malware has an ultimate goal," Brian Donohue, an intelligence analyst at Red Canary, was quoted as reporting via email. "It might be to steal sensitive information, cause damage to devices or servers, or block access to data. In this case, we don’t actually know what that ultimate goal is, because we haven’t observed Silver Sparrow engaging in malicious activity."
