Attack summary

Severity: medium — Data has been published by the group, indicating confirmed exfiltration, but no details on the volume or sensitivity of the data are available from the post. The victim is a small structural engineering firm with no indication of regulated personal data at scale, warranting a medium rather than high severity.

The Darkpower ransomware group claims to have attacked AStrEE and has published data (disclosed status: data_published); no leak post details were captured, so the specific nature of exfiltrated or encrypted data and any proof files are unknown.

Disclosure context

About Darkpower

Darkpower is a relatively obscure ransomware group that emerged in March 2023, operating with apparent financial motivations based on their targeting patterns and ransom demands. The group's origin and potential state affiliations remain unclear due to limited public documentation by major threat intelligence organizations, though their diverse geographic targeting across Turkey, Czech Republic, France, Peru, and Algeria suggests either opportunistic selection or a broad operational scope. With only 10 documented victims since their emergence, Darkpower appears to be a smaller-scale operation that has specifically focused on healthcare sector organizations, potentially indicating either specialized capabilities for compromising medical infrastructure or opportunistic targeting of organizations perceived as more likely to pay ransoms quickly due to operational criticality. The group's specific attack methodologies, initial access vectors, and technical capabilities have not been extensively documented in public threat intelligence reports from major security firms or government agencies. Given the limited public information available and the relatively small victim count, Darkpower's current operational status remains unclear, though the group has not been subject to any publicized law enforcement actions or confirmed disruptions as of late 2023. The group has been linked to 10 public disclosures across our corpus. First observed on a leak site on March 11, 2023. The operation is currently inactive.

If your organisation is affected

A listing by Darkpower means betastree.fr 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 Darkpower'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.
