The year saw a 49% increase in victims reported by ransomware leak sites, with a total of 3,998 posts from various ransomware groups. What drove this surge of activity? 2023 saw high-profile vulnerabilities like SQL injection for MOVEit and GoAnywhere MFT services. Zero-day exploits for these vulnerabilities drove spikes in ransomware infections by groups like CL0P, LockBit and ALPHV (BlackCat) before defenders could update the vulnerable software. Leak site data reveals at least 25 new ransomware groups emerged in 2023, indicating the continued attraction of ransomware as a profitable criminal activity. Despite the appearance of new groups such as Darkrace, CryptNet and U-Bomb, many of these new ransomware threat actors did not last and disappeared during the second half of the year. 2023 was an active year for international law enforcement agencies as they intensified their focus on ransomware. This focus led to the decline of groups like Hive and Ragnar Locker, and the near-collapse of ALPHV (BlackCat).
