CyberCube Report Finds Ransomware Expanding to New Territories, LockBit Group Remains Highly Active

Update:

Recent analysis indicates that despite a surge in attack volume, ransomware profits are declining, forcing groups to innovate. Key new tactics include bundling DDoS attacks to increase victim coercion, aggressively recruiting corporate insiders for initial access, and a growing number of new ransomware groups emerging from outside traditional Russian strongholds. These shifts introduce 'triple extortion' and new initial access vectors, making defense more challenging and increasing overall attack severity.
