On July 12, 2024, the Brazilian multidisciplinary hospital Instituto Respirar Londrina appeared on the leak site of the ransomcortex ransomware group. The listing states that internal files were exfiltrated during a ransomware attack on the facility, which specializes in pneumology, infectology, and thoracic surgery. Patients and staff whose personal or medical information may have been stored in those systems are now at risk of exposure.

Details from the Leak Site
The ransomcortex leak page states that data was taken from www.respirarlondrina.com.br and that the victim is a healthcare provider in Londrina, Brazil. The disclosure does not quantify the number of affected records, list specific data types beyond “internal files,” or provide a ransom demand or payment deadline. As is typical with these listings, the group published only a brief notice and a sample of the allegedly stolen material to pressure the hospital. No further technical details about the initial access vector or exact systems compromised have been released in the primary disclosure.
Why This Matters for You and Your Family
When a healthcare organization suffers a ransomware breach, the information involved is rarely limited to billing records. Patient names, dates of birth, national identification numbers, addresses, phone numbers, medical histories, and treatment details are often intermingled in the same file shares or databases. If any member of your family has received care at Instituto Respirar Londrina, those details could now sit in an attacker-controlled archive. Even without exact record counts, the exposure creates long-term privacy and financial risks that extend far beyond the hospital itself.
Doxxing and Identity-Chain Risks
Healthcare data leaks accelerate doxxing because medical files frequently contain multiple identifiers that link an individual’s real identity to usernames, email addresses, and phone numbers. Attackers or opportunistic criminals can chain this information with data from previous breaches to build complete profiles. A single leaked medical record can expose not only your health status but also serve as the anchor for further targeting of your online accounts, including gaming profiles used by children or teenagers in the same household. These credential leaks often cascade into account takeovers that lead to additional extortion or identity theft.
