$BTC faces new threat as North Korean hackers steal 400M using deepfake video calls.

DOJ disrupts "FaceStealer" scheme targeting crypto workers with AI-generated impersonations. The sophisticated attack used prerecorded footage and deepfakes of trusted contacts to trick victims into installing malware.

Key findings:

• 400M stolen over 18 months

• 1,200+ victims affected

• DOJ seizes 1.2B in related assets

This represents a dangerous evolution in crypto security threats. Traditional phishing meets AI technology.
