North Korean hackers are stepping up their game by merging two of their malware programs, BeaverTail and OtterCookie, into a more advanced threat. Cisco Talos recently reported that the notorious group, linked to the Contagious Interview campaign, is refining its toolset, making the malware even trickier to detect. The latest version of OtterCookie now includes modules for keylogging and taking screenshots, which is a significant upgrade.

This activity is tied to a cluster of threat actors that go by a bunch of names, including CL-STA-0240 and Famous Chollima. Meanwhile, Google and Mandiant revealed the hackers are using a stealthy technique called EtherHiding, allowing them to fetch payloads without raising alarms. If you’re in the cybersecurity world, keeping an eye on these developments is crucial; it’s clear these hackers are not slowing down anytime soon.
