30K Macs are infected with ‘Silver Sparrow’ virus and no one knows why
Macs and viruses aren’t all that common, but the one that was recently discovered by researchers is even less so. Security researcher Red Canary has published information about a new “activity cluster” that has infected 29,139 Macs across more than 150 countries but is missing one key ingredient: a reason to be.
In the report, Red Canary and Malwarebytes outline a new strain of macOS malware called Silver Sparrow that affects both Intel and Apple silicon processors. The companies have determined that the sheer scale of the malware is enough to pose “reasonably serious threat” even though it “did not exhibit the behaviors that we’ve come to expect from the usual adware that so often targets macOS systems.”
In short, it doesn’t do anything. That’s not all that reassuring, given that tens of thousands of Macs could have potentially been infected, but based on the findings and investigations of multiple strains, the virus was “positioned to deliver a potentially impactful payload at a moment’s notice.”
