On March 6, 2025, a radiography crew working approximately 16 km (10 mi) east of Mentone, Texas, reported losing a SPEC 150 exposure device containing a 3.53 TBq (95.4 Ci) iridium-192 source. A trainee set the exposure device on the back of the truck but failed to secure the device in the truck. The source was in the fully shielded position. Shortly after leaving the work site, the radiographers realized the exposure device was no longer in the back of the truck. The radiographers retraced the path they had traveled but did not find the device. Two other trucks passing that way were stopped but the drivers had not seen the device. The licensee has offered a cash award for the return of the device and Texas state authorities issued a press release to alert the public (https://www.dshs.texas.gov/news-alerts/dshs-notifies-public-missing-radiographic-camera-loving-county). U.S. Department of Energy Radiological Assistance Program teams have assisted the licensee and Texas state authorities

Summary

Note: This joint Cybersecurity Advisory is part of an ongoing #StopRansomware effort to publish advisories for network defenders detailing various ransomware variants and ransomware threat actors. These #StopRansomware advisories include recently and historically observed tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs) to help organizations protect against ransomware. Visit stopransomware.gov to see all #StopRansomware advisories and to learn more about other ransomware threats and no-cost resources.

The Federal Bureau of Investigation (FBI), Cybersecurity and Infrastructure Security Agency (CISA), and the Multi-State Information Sharing and Analysis Center (MS-ISAC) are releasing this joint advisory to disseminate known Medusa ransomware TTPs and IOCs, identified through FBI investigations as recently as February 2025. 

Medusa is a ransomware-as-a-service (RaaS) variant first identified in June 2021. As of February 2025, Medusa developers and affiliates have impacted over 300 victims from a variety of critical infrastructure sectors with affected industries including medical, education, legal, insurance, technology, and manufacturing. The Medusa ransomware variant is unrelated to the MedusaLocker variant and the Medusa mobile malware variant per the FBI’s investigation.

FBI, CISA, and MS-ISAC encourage organizations to implement the recommendations in the Mitigations section of this advisory to reduce the likelihood and impact of Medusa ransomware incidents.
