NCC Group released its Threat Pulse for September, which detailed a shocking increase of 153% in September for ransomware attacks. According to the report, the following groups were listed in the number of attacks:

Matt Hull (global head of Threat Intelligence at NCC Group) said, “After the drop in ransomware attacks in August, the surge in attacks during September was somewhat anticipated for this time of year. However, what stands out is the volume of these attacks and the emergence of new threat actors who have been major drivers of this activity.”
Hull continued, “These groups, including the likes of LostTrust, Cactus, and RansomedVC, are noteworthy for their approach: adapting existing ransomware techniques and introducing their own variations to add pressure for victims. We’ve witnessed a growing number of groups utilizing the double extortion model as a strategy, piggybacking off this as a successful method used by more established threat actors. New…
