Disclosure context

About Global Secret Group

Global Secret Group is a ransomware threat actor first observed in July 2026, with operations consistent with financially motivated cybercrime based on their targeting profile and victim patterns. The group has claimed or been attributed to 28 known victims across a relatively short operational window, suggesting an emerging or actively expanding operation. Given the limited public documentation available from CISA, FBI, Mandiant, or other reputable security research organizations at this time, a comprehensive technical profile cannot be fully established. What is known from available victim and targeting data indicates the group predominantly focuses on organizations in the United States, Canada, Brazil, the United Kingdom, and Cyprus, with a clear sectoral preference for Technology, Retail and E-Commerce, Energy and Utilities, Professional Services, and Financial Services — a targeting pattern broadly consistent with financially motivated ransomware actors seeking high-value data and organizations with both the ability and incentive to pay ransoms. The cross-sector and multi-national targeting pattern may suggest opportunistic intrusion methodology rather than a narrowly scoped, nation-state-aligned operation, though this assessment remains preliminary pending further public disclosure by authoritative sources. As of the time of this writing, Global Secret Group's operational infrastructure, affiliation with any ransomware-as-a-service ecosystem, specific malware tooling, and current active status have not been formally attributed or publicly documented by major threat intelligence authorities, and this profile will require revision as additional intelligence becomes available. The group has been linked to 31 public disclosures across our corpus. First observed on a leak site on July 26, 2026; most recent post July 27, 2026. The operation is currently active.

If your organisation is affected

A listing by Global Secret Group means Prism Telecom 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, NCSC-FI (Finland), as required for your jurisdiction.
Monitor for the data appearing on Global Secret Group'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.
