Disclosure context

About securotrop

Securotrop is a relatively new ransomware group that emerged in July 2025 and operates with apparent financial motivations, having targeted at least 31 victims across multiple sectors. The group primarily targets English-speaking countries including the United States, Canada, and the United Kingdom, with their attacks focused heavily on manufacturing companies, business services firms, construction organizations, and telecommunications providers. Due to the group's recent emergence and limited public documentation from major cybersecurity agencies and researchers, specific details about their country of origin, operational structure, attack methodologies, and technical capabilities remain largely undocumented in open-source intelligence reports. The targeting pattern suggests a focus on critical infrastructure and industrial sectors that may be willing to pay ransoms to quickly restore operations, though no major high-profile attacks or record ransom demands have been publicly reported by established threat intelligence sources. Given the group's recent formation in mid-2025, Securotrop appears to remain active, though comprehensive analysis of their tactics, techniques, and procedures awaits further documentation by cybersecurity researchers and law enforcement agencies. The group has been linked to 38 public disclosures across our corpus. First observed on a leak site on July 22, 2025; most recent post July 15, 2026. The operation is currently active.

If your organisation is affected

A listing by securotrop means Fasse Valves 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 securotrop'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.
