Disclosure context

About silent

The Silent ransomware group is a newly emerged cybercriminal organization first observed in April 2025, appearing to be financially motivated based on their ransomware operations targeting organizations primarily in the United States and Canada. Given the group's recent emergence and limited public documentation, their specific country of origin and operational structure remain unclear, though their targeting patterns suggest a focus on English-speaking markets. With only six known victims documented to date, detailed information about their attack methodology, encryption techniques, and specific tools remains limited in publicly available threat intelligence reporting. The group has demonstrated a preference for targeting technology companies, manufacturing organizations, and public sector entities, though the small victim sample size makes broader targeting pattern analysis preliminary. Due to the group's recent emergence in April 2025, there are no widely reported major campaigns or law enforcement actions documented by established security researchers or government agencies. Silent remains active as of current reporting, though their limited victim count and recent emergence suggest they are either a new player in the ransomware ecosystem or operate with a highly selective targeting approach. The group has been linked to 6 public disclosures across our corpus. First observed on a leak site on April 23, 2025; most recent post June 21, 2025. The operation is currently inactive.

If your organisation is affected

A listing by silent means ESP Associates 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 silent's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
