The decline in ransomware helped explain why attacks aimed at compromising corporate computers, servers and network equipment fell from 87% to 75% quarter-on-quarter, according to the authors.

The report also noted a rebranding of a number of existing ransomware gangs in Q3. For example, some of these threat actors are rethinking their preference for ransomware-as-a-service (RaaS) due to concerns about relying on third parties.

Ekaterina Kilyusheva, head of research and analytics at Positive Technologies, commented: “In Q2, we predicted that one of the possible scenarios of ransomware transformation would be that groups abandon the RaaS model in its current form. It is much safer for ransomware operators to hire people who will deliver malware and search for vulnerabilities as permanent ‘employees.’ It will be safer for both parties, as more organized and efficient a ..
