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

About the Underground group

Underground ransomware is deployed by the Russia-based RomCom group (Storm-0978) and has victimized companies across multiple industries since July 2023 by exploiting CVE-2023-36884, encrypting files without changing extensions and deleting Volume Shadow Copies and Windows event logs in double-extortion campaigns. Underground has listed 26 victims since May 2023.

Incident Analysis

Ethypharm was targeted by Underground ransomware, one of the most active ransomware groups in our database with 26 confirmed victims globally. The attack was disclosed on July 1, 2024, when Ethypharm appeared on the group's dark web leak site.

Ethypharm is based in France , operating in the Healthcare sector. France ranks #6 globally for ransomware attacks, with 517 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.

Underground 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.
