Incident Analysis

ROTO Immobilien was targeted by Qilin ransomware, one of the most active ransomware groups in our database with 1,666 confirmed victims globally. The attack was disclosed on May 21, 2026, when ROTO Immobilien appeared on the group's dark web leak site.

ROTO Immobilien is based in Austria , operating in the Construction sector. Austria ranks #29 globally for ransomware attacks, with 66 victims in our database.

Sector context: Construction firms often hold sensitive project data, client financials, and intellectual property. The industry's typically lean IT security teams can make them more vulnerable.

Qilin 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.
