Installs more malicious software and sends data back to a host server
It took less than a year for the new M1-based Mac computers to be the target of a significant, global malware attack.
Being given the name Silver Sparrow, this new malware has both an intel and M1 version for optimal reach. And the worst part about it is that it’s generic enough it’s likely to be installed on thousands of Macs and go completely recognized or untraced.
What is Silver Sparrow?
Silver Sparrow is malicious software that opens a back door to other malware. Basically, once it’s installed on your computer, it sends a signal of sorts and lets more apps install themselves without you even knowing it.
But it doesn’t stop there. Silver Sparrow stays in contact with a host server and sends copies of your data back as frequently as every hour. Typically, malware does this intending to exploit you for your sensitive or important info.
How did Silver Sparrow get on my Mac?
This is a great question. And hopefully, the answer will excuse you a little bit. Silver Sparrow is installed on Mac by mimicking a generic installer.

But, lo and behold, it’s actually a much more sophisticated attempt at getting access to your computer.
