Incident Analysis

Ouro Verde (ouroverde.net.br) was targeted by Fog ransomware, one of the most active ransomware groups in our database with 189 confirmed victims globally. The attack was disclosed on December 17, 2024, when Ouro Verde (ouroverde.net.br) appeared on the group's dark web leak site.

Ouro Verde (ouroverde.net.br) is based in Brazil , operating in the Transportation/Logistics sector. Brazil ranks #7 globally for ransomware attacks, with 464 victims in our database.

Sector context: Logistics companies are targeted because supply chain disruption has cascading effects on customers and partners, amplifying pressure to pay ransoms quickly to restore operations.

Fog 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.
