CISA, FBI unite against RansomHub threat to critical infrastructure sectors

TLDR:

• CISA, FBI, and partners issue joint advisory on RansomHub ransomware threat to critical infrastructure sectors
• RansomHub has targeted various critical infrastructure sectors since February 2024

In a joint cybersecurity advisory, CISA, FBI, MS-ISAC, and HHS have warned organizations about the RansomHub ransomware threat. RansomHub, a ransomware-as-a-service variant, has targeted critical infrastructure sectors such as water and wastewater, healthcare, transportation, and more since February 2024. The advisory provides indicators of compromise, tactics, procedures, and mitigation actions for network defenders to protect against RansomHub attacks. Affiliates of RansomHub use a double-extortion model, exfiltrating data to extort victims, and employ various methods such as phishing emails and exploiting vulnerabilities to compromise systems. Network defenders are advised to implement mitigations aligned with CISA and NIST cybersecurity performance goals, including requiring multi-factor authentication, segmenting networks, and maintaining offline backups of data. It is crucial for organizations to stay vigilant and take proactive measures to defend against the increasing ransomware threat posed by RansomHub and other malicious actors.
