Incident Analysis

Siam Oil Product was targeted by Panzer ransomware, one of the most active ransomware groups in our database with 6 confirmed victims globally. The attack was disclosed on August 9, 2026, when Siam Oil Product appeared on the group's dark web leak site.

Siam Oil Product is based in Thailand , operating in the Energy & Utilities sector. Thailand ranks #15 globally for ransomware attacks, with 166 victims in our database.

Sector context: Organisations in this sector hold valuable data and operational systems that ransomware groups seek to exploit for financial gain through encryption and data exfiltration.

Panzer 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.
