RansomHub's Modus Operandi

The group is known for its speed and efficiency, employing advanced encryption and data exfiltration techniques. RansomHub affiliates often use phishing campaigns, vulnerability exploitation, and password spraying to gain initial access to target systems. The group's ability to adapt and update its ransomware strains makes it a formidable threat to organizations worldwide.
