Unwrapping the mysteries of Shai Hulud

Keith is joined by guest host, Principal Security Researcher Brian Donohue and Red Canary Senior Intelligence Analyst Stef Rand to discuss the threats we’ve seen over the past month.

Stef touches on several items from December’s Intelligence Insights, including how Red Canary is tracking an uptick in malicious RMM use, specifically ScreenConnect, and activity from a new macOS stealer: MacSync.
