Attack summary

Severity: medium — Data has been published by the group (confirmed disclosure) and a substantial ransom demanded ($5M), indicating meaningful exfiltration. However, the post excerpt does not specify sensitive regulated data (PII at scale, financial records, medical info), and no proof files/screenshots are evident in the available text. Medium reflects confirmed publication without clear evidence of high-sensitivity data.

Eldorado claims to have exfiltrated data from Rees NDT. The group published company information and a $5 million ransom demand, though specific data categories and operational impact are not detailed in the available post excerpt.

Disclosure context

About Eldorado

Eldorado is a recently emerged ransomware group first observed in June 2024, operating with apparent financial motivations and demonstrating a relatively broad targeting approach across multiple countries and industry sectors. The group's origin and affiliations remain largely undocumented in public threat intelligence reporting, with no confirmed links to state actors or established ransomware families, though their operational patterns suggest they likely operate as an independent entity rather than a formal RaaS model. Specific technical details regarding Eldorado's initial access vectors, encryption methods, and data exfiltration capabilities have not been extensively documented in public security research, though their targeting of over 112 victims across diverse sectors including business services, technology, manufacturing, and financial services suggests they employ opportunistic attack methodologies rather than highly specialized techniques. The group has demonstrated a geographic focus primarily on the United States and Canada, with additional activity observed in Italy, UAE, and Croatia, though no specific high-profile campaigns or major ransomware incidents have been publicly attributed to this group by federal agencies or major security firms. As of current reporting, Eldorado appears to remain active with no documented law enforcement disruptions or confirmed rebranding activities, though the limited public visibility of their operations suggests they may be a smaller-scale operation compared to established ransomware families. The group has been linked to 112 public disclosures across our corpus. First observed on a leak site on June 6, 2024; most recent post January 22, 2025. The operation is currently inactive.

If your organisation is affected

A listing by Eldorado means Rees NDT Inspection Services 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, CCCS (Canada), as required for your jurisdiction.
Monitor for the data appearing on Eldorado's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
