On April 19, 2026, Brazilian clinical laboratory Laboratório Santa Luzia appeared on the leak site of the ransomware group known as thegentlemen. The company, which serves thousands of patients across nearly 30 locations in the Greater Florianópolis area, is claimed to have had internal files exfiltrated during a ransomware attack. Anyone who has had blood work, vaccinations, pediatric tests, or corporate health screenings at the lab may now have personal information at risk.

What Public Reporting Shows
Public reporting indicates that the laboratory’s data was listed on the group’s leak portal after an apparent ransomware incident. The exposed material consists of internal files that were allegedly exfiltrated before any encryption occurred. No confirmed total number of affected patients has been released, but the lab processes thousands of diagnostic tests daily across its network. The breach was first noted on April 19, 2026 via the ransomware.live aggregator that tracks thegentlemen’s activity.
The laboratory operates under the domain sluzia.com.br and maintains partnerships with local clinics, hospitals, and corporate clients. Its services include more than 2,000 types of medical tests, home collection, pediatric care, and pre-employment examinations. These records typically contain names, dates of birth, national ID numbers, contact details, test results, and in some cases payment or insurance information.
Why This Matters for You and Your Family
When a medical laboratory loses control of internal files, the information exposed is among the most sensitive data that exists about you and your loved ones. Health records can reveal chronic conditions, genetic predispositions, pregnancy status, mental-health treatments, or pediatric developmental notes. Once that data leaves the secure environment of a trusted lab, it can be sold, posted, or used to build detailed profiles for identity theft, insurance discrimination, or blackmail.
