Nearly 30,000 Macs reportedly infected with mysterious malware - CNN

The malware, which the company calls Silver Sparrow, does not "exhibit the behaviors that we've come to expect from the usual adware that so often targets macOS systems," Tony Lambert, an intelligence analyst at Red Canary wrote.

It's not clear what the malware's goal is.

Silver Sparrow includes a self-destruct mechanism that appears to have not been used, researchers said.

It's also unclear what would trigger that function.
