Incident Analysis

Rumah Sakit Universitas Indonesia (RSUI) was targeted by Nova ransomware, one of the most active ransomware groups in our database with 194 confirmed victims globally. The attack was disclosed on July 20, 2026, when Rumah Sakit Universitas Indonesia (RSUI) appeared on the group's dark web leak site.

Rumah Sakit Universitas Indonesia (RSUI) is based in Indonesia , operating in the Healthcare sector. Indonesia ranks #27 globally for ransomware attacks, with 120 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 โ€” all factors that increase ransom payment pressure.

Nova 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 โ€” 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.
