Incident Analysis

HMW was targeted by Monti ransomware, one of the most active ransomware groups in our database with 63 confirmed victims globally. The attack was disclosed on August 26, 2024, when HMW appeared on the group's dark web leak site.

HMW is based in Germany , operating in the Public Sector sector. Germany ranks #3 globally for ransomware attacks, with 839 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.

Monti 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 β€” 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.
