Disclosure context

About SilentRansomGroup

Based on the limited available information, SilentRansomGroup is a relatively new ransomware operation that first emerged in May 2025, appearing to be financially motivated given their targeting patterns across multiple high-value sectors. The group's origin and affiliations remain unclear due to their recent emergence, though their diverse geographic targeting including the United States, Germany, Canada, and Russia suggests either a sophisticated operation or potential ransomware-as-a-service model. Their attack methodology and specific technical capabilities have not been extensively documented by major security researchers, though their targeting of business services, financial services, hospitality, and manufacturing sectors indicates they likely focus on organizations with both valuable data and ability to pay significant ransoms. With 93 known victims across multiple countries and sectors in a relatively short timeframe since May 2025, SilentRansomGroup has demonstrated notable activity levels, though specific high-profile campaigns or ransom amounts have not been publicly disclosed by CISA, FBI, or major threat intelligence firms. The group appears to remain active as of current reporting periods, though comprehensive technical analysis and attribution efforts by established security researchers are still developing given their recent emergence in the threat landscape. The group has been linked to 120 public disclosures across our corpus. First observed on a leak site on May 6, 2025; most recent post June 17, 2026. The operation is currently active.

If your organisation is affected

A listing by SilentRansomGroup means Barclay Damon 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, CISA (United States), as required for your jurisdiction.
Monitor for the data appearing on SilentRansomGroup'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.
