Incident Analysis

Universite Paris Sud was targeted by Ransomhouse ransomware, one of the most active ransomware groups in our database with 150 confirmed victims globally. The attack was disclosed on October 9, 2024, when Universite Paris Sud appeared on the group's dark web leak site.

Universite Paris Sud is based in France , operating in the Education sector. France ranks #6 globally for ransomware attacks, with 525 victims in our database.

Sector context: Educational institutions often have under-resourced IT security teams and hold large amounts of student and faculty personal data, making them attractive targets for ransomware groups.

Ransomhouse 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.
