Disclosure context

About settra

Settra is a ransomware group first observed in June 2026 with an apparent primary motivation of financial gain, having claimed at least 11 victims within a relatively short operational window. Given the recency of their emergence and limited public documentation from major threat intelligence sources such as CISA, FBI, or Mandiant at this time, detailed technical attribution remains unconfirmed. Their targeting pattern shows a geographic concentration in the United States, Taiwan, Portugal, Singapore, and Canada, suggesting an opportunistic rather than narrowly focused regional strategy. Affected sectors include Consumer Services, Manufacturing, Transportation and Logistics, and Agriculture and Food Production, indicating the group does not restrict itself to a single vertical and likely prioritizes target accessibility over sector-specific expertise. No publicly documented information is currently available to confirm their country of origin, RaaS affiliation, specific initial access vectors, encryption methodology, or extortion tactics, and no major law enforcement actions against the group have been publicly reported as of this writing. Given their nascent operational timeline and limited victim count, Settra should be considered an emerging threat actor warranting continued monitoring as their tactics, techniques, and procedures become better characterized through future incident reporting and threat intelligence disclosures. The group has been linked to 22 public disclosures across our corpus. First observed on a leak site on June 28, 2026; most recent post June 30, 2026. The operation is currently active.

If your organisation is affected

A listing by settra means petradiamonds.com 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 (United Kingdom), as required for your jurisdiction.
  • Monitor for the data appearing on settra'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.
