Affects: CrowdStrike researchers tracked an adware campaign that injects ads into Chrome and Safari browsers on macOS. Victims are tricked into opening a DMG file and running a shell script which masquerades as a legitimate installer application. The shell script modifiers browser settings that allow ads to display.
The Chrome version of the install script loads a malicious Chrome extension to monitor browser activity.
The campaign leverages a combination of AppleScript and Python to infect devices.
Prevented by: Jamf Protect tracks this adware campaign and threat prevention rules block its execution as of March 22, 2022.
