ThreatAI Analysis

Compiled from this incident record and the threat intelligence profile for Benzona. Figures and technique mappings are quoted from the source data, not inferred.

About the Benzona group

Benzona is a financially motivated ransomware group that emerged in late 2024, targeting small to mid-sized organizations across manufacturing, healthcare, technology, and hospitality sectors using double-extortion tactics — encrypting files while exfiltrating data and threatening publication via a Tor-based leak site. Benzona has listed 14 victims since November 2025.

Incident Analysis

sevci.org was targeted by Benzona ransomware, one of the most active ransomware groups in our database with 14 confirmed victims globally. The attack was disclosed on November 26, 2025, when sevci.org appeared on the group's dark web leak site.

sevci.org is based in CI , operating in the Healthcare sector. CI ranks #102 globally for ransomware attacks, with 6 victims in our database.

Sector context: Healthcare organisations are high-value ransomware targets because patient data is extremely sensitive, regulatory penalties for breaches are severe, and operational downtime can threaten patient safety — all factors that increase ransom payment pressure.

Benzona typically employs a double extortion model: first exfiltrating sensitive data from the victim's systems, then deploying ransomware to encrypt files. Victims face two simultaneous threats — paying to restore access and paying to prevent publication of stolen data. The group's leak site publishes victim names and exfiltrated data as leverage.

Data source: This incident record is sourced from public ransomware group leak site disclosures aggregated via the ransomware.live API. Disclosure date reflects when the victim was published on the leak site, which may differ from the initial date of compromise. This platform does not publish or link to stolen data.
