Foxconn confirmed Tuesday that a cyberattack hit several North American factories, with its Wisconsin Mount Pleasant facility halting production for a week starting May 1. Workers were told to power off computers and revert to paper timesheets. Nitrogen ransomware group claimed responsibility, posting 8 TB of stolen data covering 11 million files - allegedly including project documentation tied to Apple, Intel, Google, Dell, AMD, and Nvidia. Foxconn says production is resuming. This is the fourth ransomware attack on a Foxconn entity since 2020.
Update on the Head Mare campaign we covered April 28: Kaspersky now reports that BO Team (also known as Black Owl) and Head Mare appear to be coordinating cyber operations against Russian organizations, sharing command-and-control infrastructure on the same compromised hosts. The likely division of labor: Head Mare phishes for initial access, then BO Team takes over for malware deployment. BO Team has shifted from destructive attacks to covert espionage, and in Q1 2026 hit 20 Russian organizations across manufacturing, telecoms, and oil and gas. The group uses BrockenDoor and Remcos backdoors. Earlier BO Team campaigns hit a Russian drone supplier and the federal digital signature authority.
