Disclosure context

About Storm

Storm is a ransomware group first observed in August 2026, operating with an apparent financial motivation based on its targeting profile, though limited public documentation exists given its recent emergence and relatively small victim footprint. The group has claimed or been attributed to attacks against at least six known victims, with the United States representing its primary target geography. Storm has demonstrated a preference for targeting the healthcare and manufacturing sectors, alongside a broader category of other industries, suggesting an opportunistic rather than highly specialized targeting philosophy. Due to the group's recent emergence and limited victim count, comprehensive technical details regarding its initial access vectors, encryption methodology, tooling, or affiliation with known threat actor ecosystems have not yet been formally documented by CISA, the FBI, Mandiant, or other major threat intelligence publishers as of the time of this writing. No confirmed RaaS infrastructure, dark web leak site activity, or law enforcement actions against the group have been publicly attributed or reported in open sources. Given its nascent operational timeline beginning in 2026, Storm should be monitored as an emerging threat, particularly within the healthcare sector where ransomware attacks carry significant operational and patient safety implications, but analysts should treat any further characterization beyond the known victim and targeting data with caution pending additional corroborating intelligence. The group has been linked to 61 public disclosures across our corpus. First observed on a leak site on August 7, 2026; most recent post September 18, 2026. The operation is currently active.

If your organisation is affected

A listing by Storm means The State Bank 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 Storm'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.
