Description

The RansomHub ransomware, attributed to a group tracked as Water Bakunawa, employs sophisticated anti-EDR techniques to evade security solutions. Its attack chain includes exploiting vulnerabilities like Zerologon, using EDRKillShifter to disable endpoint protection, and employing various evasion scripts. The ransomware targets multiple industries and critical infrastructure sectors, using spear-phishing for initial access. It utilizes tools like NetScan for network reconnaissance and AnyDesk for command and control. The attackers exfiltrate sensitive data using rclone before encrypting files and demanding ransom. The evolving tactics of RansomHub highlight the need for advanced, multi-layered security strategies to protect against modern ransomware threats.
