The report details the guilty plea of Angelo Martino, a former ransomware negotiator who secretly assisted the BlackCat/ALPHV group in 2023 by sharing victim-sensitive negotiation details and later participating in attacks that extorted multiple U.S. companies (one victim paid about $1.2M); co-conspirators Ryan Goldberg and Kevin Martin also pleaded guilty, funds were laundered, and authorities seized roughly $10M in assets.
