ThreatAI Analysis

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

About the Blackout group

Blackout is a ransomware group that first appeared in early 2024, initially claiming attacks against healthcare entities in Canada, France, and Germany before expanding to telecommunications, mining, and manufacturing sectors, operating a double-extortion model with a data leak site. Blackout has listed 12 victims since February 2024.

Incident Analysis

luzan5.com was targeted by Blackout ransomware, one of the most active ransomware groups in our database with 15 confirmed victims globally. The attack was disclosed on July 14, 2024, when luzan5.com appeared on the group's dark web leak site.

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.

Blackout 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. Last data update: Sep 7, 2026 16:00 UTC.
