Disclosure context

About Booba Project

Booba Project is a nascent ransomware group first observed in July 2026, operating with an apparent financial motivation based on its targeting patterns, though limited public documentation exists given its recent emergence and small victim footprint. The group has claimed or been attributed to at least four known victims, with activity concentrated in Spain and the United States, spanning sectors including telecommunications, agriculture and food production, and technology, suggesting opportunistic rather than highly targeted sector-specific campaigns. Due to the group's recency and limited victim count, no detailed technical analysis of their tooling, initial access vectors, encryption methodology, or extortion tactics has been publicly documented by CISA, the FBI, Mandiant, or other reputable threat intelligence sources at this time. No notable high-profile campaigns, record ransoms, or law enforcement actions have been publicly attributed to Booba Project as of the available reporting period. Given its first observation date of July 2026 and minimal public reporting, the group should be considered emergent and actively monitored, with its operational status, potential RaaS affiliation, and country of origin remaining unconfirmed pending further intelligence collection and disclosure by authoritative cybersecurity organizations. The group has been linked to 20 public disclosures across our corpus. First observed on a leak site on July 6, 2026; most recent post September 22, 2026. The operation is currently active.

If your organisation is affected

A listing by Booba Project means Tulare Western High School 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 Booba Project'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.
