Attack summary

Severity: medium — Data is marked as published (data_published), indicating exfiltration and release occurred, but no leak post details are available to confirm the type, scale, or sensitivity of the data; the company handles B2B industrial supply which may include procurement, contracts, and client PII, warranting medium severity in the absence of further detail.

The Toufan ransomware group claims a disclosed attack against US Tool Group with data published status; no leak post text was captured, so specific claims about encryption or exfiltration volume cannot be confirmed from the post alone.

Disclosure context

About toufan

Toufan is a ransomware group that emerged in December 2023, operating with apparent financial motivations and demonstrating a preference for targeting victims across Israel, Canada, Singapore, Australia, and Great Britain. The group has claimed responsibility for compromising 117 victims since its emergence, though detailed public documentation from major threat intelligence firms regarding their specific origin, country of operation, or organizational structure remains limited. Given the recent emergence of this group and the geographic distribution of their targeting, comprehensive technical analysis of their attack methodologies, encryption techniques, and initial access vectors has not been extensively documented in public threat intelligence reporting from established security research organizations. The group's targeting pattern suggests a focus on English-speaking countries and Israel, though the specific sectors or victim profiles they prioritize, along with details about ransom demands or notable high-profile compromises, have not been widely reported in mainstream cybersecurity intelligence channels. As a recently emerged threat actor first observed in late 2023, Toufan appears to remain active based on the accumulation of claimed victims, though comprehensive assessment of their current operational status requires further monitoring and analysis by established threat intelligence communities. The group has been linked to 117 public disclosures across our corpus. First observed on a leak site on December 17, 2023; most recent post December 27, 2023. The operation is currently inactive.

If your organisation is affected

A listing by toufan means ustg.net 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 toufan'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.
