Summary Points Two cybersecurity professionals, Ryan Goldberg and Kevin Martin, pleaded guilty to running a ransomware extortion scheme using BlackCat (ALPHV), targeting five US companies between April and December 2023. They identified victims, utilized ransomware-as-a-service, and shared ransom payouts with the developers; their attacks resulted in over $9.5 million in losses, with only $324,123 recovered. The US Department of Justice will sentence them on March 12, 2026, facing a maximum of 20 years in prison, amid ongoing efforts to dismantle the BlackCat group, which targeted over 1,000 victims globally. The FBI decommissioned BlackCat’s operations in December 2023 by developing a…

Top Highlights Two cybersecurity professionals, Ryan Goldberg and Kevin Martin, pleaded guilty to conspiracy to commit extortion via ransomware, having used their skills to deploy ALPHV BlackCat ransomware instead of stopping cyberattacks. They exploited their computer security expertise, successfully extorting victims for around $1.2 million, and shared ransom proceeds with BlackCat operators under a ransomware-as-a-service model. The FBI, which developed a decryption tool saving victims $99 million, seized websites and targets over 1,000 victims worldwide, intensifying efforts to dismantle the BlackCat group. This case highlights the risk of trusted security professionals turning into cybercriminals, emphasizing the need for strict background…
