Disclosure context

About medusalocker

MedusaLocker is a ransomware group that emerged in November 2022, operating with primarily financial motivations and targeting organizations across multiple sectors including technology, energy, healthcare, and manufacturing. The group's origin and specific affiliations remain largely undocumented in public threat intelligence reports, though their operational patterns suggest they may operate as part of the broader ransomware-as-a-service ecosystem that has proliferated in recent years. With 51 documented victims primarily concentrated in the United States, United Arab Emirates, Germany, Canada, and Antigua and Barbuda, MedusaLocker appears to focus on opportunistic targeting rather than specific geographic or sectoral specialization. The group's attack methodology and specific technical capabilities have not been extensively documented by major threat intelligence organizations, though their targeting of critical infrastructure sectors including healthcare and energy suggests they likely employ common ransomware tactics such as network encryption and potential data exfiltration. No major high-profile attacks or significant law enforcement disruptions against MedusaLocker have been publicly reported by CISA, FBI, or other major security agencies. The current operational status of MedusaLocker remains unclear due to limited public documentation, though the relatively recent emergence date suggests the group may still be active or have transitioned to other operations. The group has been linked to 67 public disclosures across our corpus. First observed on a leak site on November 15, 2022; most recent post May 5, 2026. The operation is currently active.
