Disclosure context

About tengu

Tengu is a recently emerged ransomware group first observed in October 2025, operating with apparent financial motivations and demonstrating a geographically diverse targeting approach across 49 documented victims. The group has primarily focused their operations on Morocco, the United States, India, Italy, and Indonesia, suggesting either opportunistic targeting or specific interest in these regions' economic sectors. Their victim profile spans multiple industries including technology, manufacturing, public sector, and agriculture and food production, indicating a broad targeting strategy rather than sector-specific focus. Due to the group's recent emergence and limited public documentation from established threat intelligence sources, specific details regarding their origin, affiliation status, technical methodology, encryption techniques, and operational structure remain largely undocumented by major cybersecurity agencies and research organizations. No notable high-profile campaigns or law enforcement actions have been publicly reported by CISA, FBI, or prominent security researchers at this time. The group's current operational status appears active given their recent emergence, though comprehensive threat intelligence profiles from established sources have yet to be published due to their nascent presence in the ransomware landscape. The group has been linked to 59 public disclosures across our corpus. First observed on a leak site on October 23, 2025; most recent post May 28, 2026. The operation is currently active.

If your organisation is affected

A listing by tengu means Al Arif Contracting Co. (L.L.C) 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.
Monitor for the data appearing on tengu's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
