Summary from the TLDR InfoSec newsletter

The Ferret family of malware is used by the Contagious Interview campaign targeting developers using macOS. The campaign involves victims being sent a link to communicate with an interviewer that throws an error and prompts the user to download a trojanized virtual meeting software which installs a Go backdoor and stealer. The newest variant uses a valid Apple Developer signature and Team ID, evades the current XProtect signatures, and masquerades as a Zoom application.
