Ransomware gold rush

Recent months were no short of large scale ransomware attacks. Attacks against Colonial Pipeline and meatpacker JBS were dominating the news for several weeks.

Research by CyberNews shows that criminal groups to expand, actively recruiting new employees. Our researcher even tricked ransomware operators into revealing the payout structure, cash-out schemes, and target acquisition strategies.

Ransomware groups advertise online, claiming the successful candidate would get up to 80% of any successfully paid ransom. Criminals could even prove they have $1 million worth of bitcoin in one of their digital wallets.

The group our researcher tried to infiltrate is the Russia-linked cyber gang Ravil, also going by the name Sodinokibi. The same group is likely responsible for the disruption of JBS operations in the US, slaughtering plants for a day after the attack.

JBS later admitted to paying $11 million worth of bitcoin to put an end to the attack. According to the FBI, the company says that JBS has fallen victim to ‘specialized and sophisticated cybercriminal groups in the world.’
