The article discusses the Ransomhub ransomware’s utilization of EDRKillShifter to disable EDR and antivirus protections. Ransomhub also exploits the Zerologon vulnerability to take control of networks without authentication. The group has attacked various industries, employed spear-phishing, and used the affiliate model. Trend Micro’s Vision One telemetry data aided in uncovering Ransomhub’s tactics. It is imperative for organizations to enhance their security measures to fend off such threats.
Based on the meeting notes, here are the key takeaways:
1. Ransomhub, known for its affiliate model, employs various anti-EDR techniques, including the use of EDRKillShifter, to evade detection and prolong its presence within compromised systems or networks.
2. The attack chain of RansomHub ransomware includes exploiting the Zerologon vulnerability (CVE-2020-1472) and employing multiple spear-phishing attempts, indicating that the ransomware attacks are targeted.
3. RansomHub has been attributed to ransomware attacks across various industries and critical infrastructure sectors, such as water and wastewater, IT, commercial and government services and facilities, healthcare, agriculture, financial services, manufacturing, transportation, and communications.
4. The ransomware group has successfully targeted and compromised 210 organizations, as reported by the FBI.
5. To defend against RansomHub and similar threats, organizations are advised to strengthen endpoint protection, implement driver- and kernel-level protections, enforce credential and authentication security, enable behavioral monitoring and anomaly detection, and harden the endpoints’ security configurations.
6. Trend Micro’s Vision One provides comprehensive telemetry and advanced analytical capabilities, allowing for the dissection and understanding of the sophisticated methods employed by RansomHub.
7. The meeting notes also provide extensive technical details of RansomHub’s attack chain, including the evasion, credential access, discovery, lateral movement, command and control, exfiltration, and impact phases, with specific examples of malicious activities and associated MITRE ATT&CK techniques.
