Incident Analysis

EcoPetróleo was targeted by Medusa ransomware, one of the most active ransomware groups in our database with 372 confirmed victims globally. The attack was disclosed on October 14, 2025, when EcoPetróleo appeared on the group's dark web leak site.

EcoPetróleo is based in Dominican Republic , operating in the Energy sector. Dominican Republic ranks #54 globally for ransomware attacks, with 23 victims in our database.

Sector context: Energy sector attacks can have critical infrastructure implications. Ransomware on operational technology (OT) networks can disrupt power generation and distribution, elevating the urgency of recovery.

Medusa 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.
