The memedusalockerdusa ransomware group is an obscure threat actor that first emerged in November 2022, operating with apparent financial motivations typical of ransomware operations. Limited public documentation exists regarding this group's origin, affiliation, or operational structure, with no confirmed links to known ransomware families or evidence of Ransomware-as-a-Service operations based on available intelligence from major security firms and law enforcement agencies. The group's attack methodology, tooling, and technical capabilities remain largely undocumented in public threat intelligence reports, with no confirmed details regarding their initial access vectors, encryption methods, or whether they employ data exfiltration tactics commonly associated with modern ransomware operations. With only one publicly documented victim since their emergence, memedusalockerdusa has maintained an exceptionally low profile compared to prominent ransomware groups, generating minimal coverage from established security researchers at Mandiant, CrowdStrike, or similar organizations. The current operational status of memedusalockerdusa remains unclear due to limited visibility into their activities and the absence of recent public reporting on their operations. The group has been linked to 1 public disclosures across our corpus. First observed on a leak site on November 15, 2022. The operation is currently inactive.
How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
