Disclosure context

About Madliberator

Madliberator is a recently emerged ransomware group first observed in July 2024, operating with apparent financial motivations and demonstrating a focused targeting approach across multiple continents. Based on their targeting pattern spanning Spain, Italy, Germany, South Korea, and South Africa, the group appears to operate internationally with no clear geographic origin established by security researchers, and their operational model as either independent operators or ransomware-as-a-service remains undetermined due to limited public documentation. With only 16 documented victims since their emergence, specific details about their attack methodology, initial access vectors, encryption techniques, and whether they employ double or triple extortion tactics have not been extensively documented by major security firms or government agencies. The group has primarily targeted business services, manufacturing, financial services, and government sectors, though no specific high-profile incidents or record ransom demands have been publicly reported by CISA, FBI, or established threat intelligence providers. As of current reporting, Madliberator appears to remain active given their recent emergence and ongoing targeting activities, though comprehensive analysis remains limited due to the group's relatively small victim count and recent operational timeline. The group has been linked to 16 public disclosures across our corpus. First observed on a leak site on July 17, 2024; most recent post October 1, 2024. The operation is currently inactive.

If your organisation is affected

A listing by Madliberator means ych.com appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

  • Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
  • Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
  • Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
  • Report the incident to your national CERT, CISA (United States), as required for your jurisdiction.
  • Monitor for the data appearing on Madliberator's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

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.
