Disclosure context

About Darkvault

Darkvault is an emerging ransomware group first observed in April 2024, operating with apparent financial motivations and demonstrating a broad international targeting approach across multiple high-value sectors. The group's origin and specific affiliations remain undocumented in public threat intelligence reporting, though their operational patterns suggest a financially motivated cybercriminal organization rather than state-sponsored activity. Given the limited public documentation from established security research organizations, specific details regarding Darkvault's attack methodology, initial access vectors, encryption techniques, and potential data exfiltration practices have not been comprehensively analyzed or reported by major threat intelligence providers such as CISA, FBI, or Mandiant. The group has reportedly compromised approximately 55 victims across diverse geographic regions, with particular concentration in India, the United States, Brazil, the United Kingdom, and South Korea, while demonstrating sector preferences for technology companies, business services, healthcare organizations, transportation and logistics firms, and financial institutions. Due to the group's recent emergence and limited coverage in established threat intelligence channels, comprehensive details regarding notable high-profile campaigns, ransom demands, or specific law enforcement actions remain undocumented in publicly available security research. Current intelligence suggests the group maintains active operations as of late 2024, though the limited public reporting on Darkvault indicates either highly effective operational security or insufficient analysis by major cybersecurity research organizations. The group has been linked to 55 public disclosures across our corpus. First observed on a leak site on April 11, 2024; most recent post January 6, 2025. The operation is currently inactive.

If your organisation is affected

A listing by Darkvault means cosimti.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.
Monitor for the data appearing on Darkvault'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.
