Disclosure context

About benzona

Benzona is an emerging ransomware group that was first observed in November 2025, operating with apparent financial motivations based on their targeting patterns across multiple sectors and geographic regions. The group has conducted at least 14 documented attacks within a short timeframe since their emergence, suggesting an active operational tempo. Given the limited public documentation available from major threat intelligence sources, specific details regarding the group's country of origin, potential affiliations, or operational model remain unclear, though their diverse geographic targeting spanning Romania, India, Côte d'Ivoire, Taiwan, and France suggests either a broad operational scope or potential ransomware-as-a-service model. The group's attack methodology and technical capabilities have not been extensively documented in public threat intelligence reporting, though their targeting of healthcare, manufacturing, hospitality and tourism, and technology sectors indicates they may be opportunistic in their victim selection rather than following highly specialized targeting criteria. No major high-profile campaigns or significant law enforcement actions against Benzona have been publicly reported by CISA, FBI, or major security firms, likely due to the group's recent emergence and relatively limited scale of operations compared to established ransomware families. Given the group's recent first observation date of November 2025, Benzona appears to remain active, though comprehensive threat intelligence profiles from established security researchers have not yet been published due to the group's nascent operational history. The group has been linked to 14 public disclosures across our corpus. First observed on a leak site on November 26, 2025; most recent post January 30, 2026. The operation is currently active.
