The volume of known ransomware attacks surged last month to record-breaking levels, security researchers report.
Ransomware groups collectively listed 514 victims on their data-leak sites in September, breaking the previous record in July of 502 victims, said U.K. cybersecurity firm NCC Group. The firm reports that “major drivers of this activity” include newer groups such as LostTrust, Cactus, and RansomedVC.
