The Nokoyawa ransomware-as-a-service (RaaS) operator, ‘farnetwork’, was involved in malware development and operation management for various affiliate programs. A cybersecurity company, Group-IB, reported their activities and revealed their connections to ransomware operations since 2019. Despite retiring the Nokoyawa RaaS program, it is believed that farnetwork will rebrand and continue their activities. They acted as a project leader, affiliate recruiter, and botnet manager, offering affiliates access to compromised networks. The affiliates had to escalate privileges, steal files, and demand ransoms. Group-IB discovered connections between farnetwork and JSWORM, Nemty, Nefilim, and Karma ransomware.
