Area 1 Security’s Response to Silver Sparrow

Security Bulletin: Silver Sparrow Malware Affecting Apple Mac Products


Area 1 Security is aware of the Silver Sparrow Malware that is currently affecting Apple Mac products utilizing both the Intel x86_64 architecture as well as the new M1 ARM64 chip set.

Researchers at Red Canary and Malwarebytes have stated that Silver Sparrow utilizes malicious JavaScript to initiate a persistent command and control connection and take over the affected machines. The malware is installed on machines via a .pkg file named “updater [dot] pkg”.

  • Area 1 does not allow .pkg or other executable files to be delivered via email. This protects our customers from being able to install the malicious files on their machines via email.
  • Area 1 has also added the known command and control URL’s to our global protection for all of our customers.
  • Area 1 will continue to monitor any new information that becomes available and update our protections accordingly.

Area 1 Security Recommendations
