Disclosure context

About ralord

Ralord is an emerging ransomware group first observed in March 2025, operating with primarily financial motivations based on their victim targeting patterns across multiple countries and sectors. The group's origin and affiliations remain unclear due to limited public documentation from established threat intelligence sources, though their targeting of Spanish and Brazilian organizations alongside other Latin American and European countries suggests possible regional familiarity or language capabilities. With only 19 documented victims since their emergence, ralord appears to operate as a smaller-scale ransomware operation, focusing primarily on manufacturing, hospitality and tourism, education, and technology sectors across Spain, Brazil, Saudi Arabia, France, and Argentina. The group's specific attack methodologies, initial access vectors, and whether they employ double or triple extortion tactics have not been publicly documented by major cybersecurity firms or law enforcement agencies. Due to the group's recent emergence and limited public reporting, no notable high-profile campaigns or significant ransoms have been documented in open-source intelligence reports from CISA, FBI, or established security research organizations. Given the recency of their first observed activity in March 2025, ralord appears to remain active, though comprehensive threat intelligence profiles from major security vendors have yet to be published. The group has been linked to 19 public disclosures across our corpus. First observed on a leak site on March 26, 2025; most recent post April 27, 2025. The operation is currently inactive.

If your organisation is affected

A listing by ralord means Élan Sportif Nantes 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, CERT-FR (France), as required for your jurisdiction.
  • Monitor for the data appearing on ralord'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.
