Two former cybersecurity workers pleaded guilty for participation in a BlackCat (ALPHV) ransomware extortion campaign that hit multiple U.S. victims, showing how affiliate access and insider experience can scale criminal operations. The campaign ran from May 2023 to November 2023 and tied intrusions to a 20% share of ransoms for access to BlackCat's platform. Victims included companies in pharmaceuticals, engineering, medical devices, drones, and healthcare, and one victim paid $1.27 million after its servers were encrypted.
