chmsbc.org.br Listed by lockbit5 Ransomware Group

On August 14, 2025, the Brazilian hospital network Complexo Hospitalar de São Bernardo do Campo appeared on the LockBit 5 ransomware leak site with internal files listed for public download after the organization apparently refused to pay an extortion demand.

What Public Reporting Shows

Public reporting indicates that attackers exfiltrated internal files from the hospital’s systems and published a sample on the LockBit 5 dark-web portal. The Complexo Hospitalar de São Bernardo do Campo, which includes the Hospital de Clínicas, provides care to a large patient population in the São Paulo metropolitan area. No exact victim count has been released, and the precise volume of stolen data remains unclear from available screenshots and postings. The listing follows the group’s standard pattern of first encrypting victim networks, then exfiltrating selected directories before threatening to publish them if ransom is not paid.

Industry research from sources such as DoxxScan™ continuous monitoring indicates that healthcare organizations continue to face elevated risk because medical records, insurance details, and staff credentials hold long-term resale value on criminal markets.

Why This Matters for You and Your Family

When a hospital’s internal files are stolen, the information often includes patient names, dates of birth, national ID numbers, addresses, phone numbers, email accounts, and sometimes treatment or insurance records. If your family has ever received care at facilities connected to Complexo Hospitalar de São Bernardo do Campo, those details may now sit in an attacker’s archive. Stolen healthcare data tends to circulate for years because it can be used to file fraudulent claims, open accounts in your name, or pressure you with embarrassing personal details.
