Disclosure context

About Darkrace

Darkrace is a relatively new ransomware group that emerged in May 2023, operating with primarily financial motivations through targeted extortion campaigns. The group demonstrates a preference for targeting European nations, particularly Italy, Sweden, and Portugal, while also conducting operations against victims in Japan and Switzerland, suggesting a broad international scope despite their limited scale of operations. With only 10 documented victims since their emergence, Darkrace appears to operate as a smaller, independent ransomware operation rather than a large-scale Ransomware-as-a-Service enterprise, though specific details regarding their country of origin and potential affiliations with other cybercriminal groups remain undocumented in public threat intelligence reporting. Due to the limited public documentation from major cybersecurity firms and law enforcement agencies regarding Darkrace's specific attack methodologies, encryption techniques, and initial access vectors, their operational tactics and technical capabilities are not well-established in current threat intelligence databases. The group has not been associated with any major, high-profile ransomware incidents that have drawn significant public attention or law enforcement response, likely due to their relatively small victim count and recent emergence in the threat landscape. Current intelligence suggests Darkrace remains active as of late 2023, though their limited operational footprint and absence from major cybersecurity advisories indicates they represent a lower-tier threat compared to more established ransomware operations. The group has been linked to 10 public disclosures across our corpus. First observed on a leak site on May 31, 2023; most recent post June 9, 2023. The operation is currently inactive.

If your organisation is affected

A listing by Darkrace means hep global GmbH 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, JPCERT/CC (Japan), as required for your jurisdiction.
Monitor for the data appearing on Darkrace'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.
