OldGremlin has resumed extortion attacks against Russian industrial enterprises, creating renewed operational risk for as many as eight large domestic targets. The group used phishing email campaigns to deliver the initial access path and move the activity into victim environments. The reported timeframe places the operation in the first half of 2025, indicating an active and continuing campaign thread. The scope suggests a targeted, multi-victim extortion operation rather than an isolated intrusion.
