Disclosure context

About d4rk4rmy

d4rk4rmy is a recently emerged ransomware group that was first observed in July 2025, operating with apparent financial motivations based on their targeting of high-value sectors including financial services and technology organizations. With only 18 documented victims to date, the group appears to be in its early operational phase, demonstrating a geographically diverse targeting approach across the United States, Taiwan, Brazil, Poland, and Monaco, with particular focus on financially lucrative sectors such as financial services, technology, transportation and logistics, and hospitality and tourism industries. Given the group's recent emergence and limited public documentation from established threat intelligence sources, specific details regarding their country of origin, operational structure, attack methodologies, encryption techniques, and whether they operate as a Ransomware-as-a-Service model remain largely undetermined by major cybersecurity organizations such as CISA, FBI, or prominent security research firms. The group's current operational status appears active based on the recent timeline of their emergence, though comprehensive analysis of their capabilities, notable campaigns, and potential law enforcement actions is limited due to insufficient publicly available intelligence from authoritative sources. The group has been linked to 18 public disclosures across our corpus. First observed on a leak site on July 7, 2025; most recent post August 16, 2025. The operation is currently inactive.

If your organisation is affected

A listing by d4rk4rmy means BIG SILVER 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 d4rk4rmy'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.
