The indictment alleges MonsterCloud used ransom payments as a hidden service
The Justice Department said Pinhasi claimed MonsterCloud offered a principled alternative to paying ransomware attackers. Prosecutors allege that he had no special technology to decrypt data and instead contacted and paid the cybercriminals who had attacked a client in exchange for a decryption key.
The department alleges that MonsterCloud typically charged a client substantially more than the ransom it secretly paid. In or around August 2023, it alleges that Pinhasi paid approximately $8,200 to a cybercriminal and charged the client approximately $150,000.
The alleged scheme included claims about decryption tools and customer results
The Hacker News reported that MonsterCloud claimed to have “proprietary tools” and “advanced decryption techniques” that could recover encrypted data without yielding to ransom demands.
The Hacker News also reported that, in another incident around October 2021, Pinhasi allegedly paid approximately $236,000 and charged the customer about $380,000.
Bitdefender reported that prosecutors said MonsterCloud displayed customer testimonials, including some involving paid spokespersons.
FBI investigation follows charges in federal court
Bitdefender reported that Pinhasi, also known as Zack Silver and Zack Green, was arraigned Oct. 7 in federal court in Brooklyn. The Justice Department said the FBI is investigating the case.
The Justice Department said FBI and CISA guidance does not recommend that ransomware victims pay ransom. It said paying does not ensure that data will be decrypted, systems or data will no longer be compromised, or data will not be leaked.
The FBI is investigating the case. If convicted, Pinhasi faces a maximum penalty of 20 years on each count.
The Justice Department said an indictment is merely an allegation and that defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
What to do now
- Do not pay ransom, following FBI and CISA guidance.
- Before an incident happens, identify reputable incident-response providers and establish a response plan.
