Today, CISA—in partnership with the FBI (FBI) and Multi-State Information Sharing and Analysis Center (MS-ISAC)—released a joint Cybersecurity Advisory, #StopRansomware: Ghost (Cring) Ransomware. This advisory provides network defenders with Indicators of Compromise (IOC) (IOCs), tactics, techniques, and procedures (TTPs), and detection methods associated with Ghost ransomware activity identified through FBI investigations.

Ghost actors conduct these widespread attacks targeting and compromising organizations with outdated versions of software and firmware on their internet facing services. These malicious ransomware actors are known to use publicly available code to exploit Common Vulnerabilities and Exposures (CVE) (CVEs) where available patches have not been applied to gain access to internet facing servers. The known CVEs are CVE-2018-13379, CVE-2010-2861, CVE-2009-3960, CVE-2021-34473, CVE-2021-34523, CVE-2021-31207.

Cybersecurity and Infrastructure Security Agency (CISA) encourages network defenders to review this advisory and apply the recommended mitigations. See #StopRansomware and the #StopRansomware Guide for additional guidance on ransomware protection, detection, and response. Visit CISA’s Cross-Sector Cybersecurity Performance Goals for more information on the CPGs, including added recommended baseline protections.
