When researchers responded to an ad to join up with a ransomware-as-a-service (RaaS) operation, they wound up in a cybercriminal job interview with one of the most active threat actors in the affiliate business, who turns out to be behind at least five different strains of ransomware.

Meet “farnetwork,” who was unmasked after giving over too many specifics to a Group-IB threat researcher pretending to be a potential affiliate for the Nokoyawa ransomware group. The cybercriminal is also known by aliases including jingo, jsworm, razvrat, piparuka, and farnetworkit, the team learned.
