A 41-year-old former ransomware negotiator has been sentenced to nearly six years (i.e., 70 months) in prison in the U.S. for their role in conspiring with the now-defunct BlackCat ransomware operators to extort multiple victims and working with two other cybersecurity professionals to target additional victims in 2023.

In a sentencing memorandum, federal prosecutors described Martino as a “double agent working to maximize the harm to his clients and the financial gain to cybercriminals who paid him a part of the ransom.”

Angelo Martino, 41, of Land O’Lakes, Florida, pleaded guilty to one-count information charging him with conspiring to interfere with interstate commerce through extortion back in April. The defendant worked as a negotiator on behalf of five different ransomware victims, while providing BlackCat attackers with confidential information regarding their negotiating position and strategy without their knowledge or permission.
