nuclep.gov.br. Nuclep Brazil Listed by Babuk2 Ransomware Group

On March 13, 2025, Brazilian state-owned nuclear company Nuclep had its internal files listed on the leak site operated by the Babuk2 ransomware group. The posting states that attackers exfiltrated data from nuclep.gov.br during a ransomware incident, although the exact number of affected individuals remains unknown.

What Public Reporting Shows

Public reporting indicates the Babuk2 group published a sample of Nuclep’s internal documents on its dark-web leak site. The data consists of internal files exfiltrated after the company’s systems were encrypted. No customer records or specific personal data types have been detailed in the initial posting, but the nature of a nuclear engineering firm suggests technical, operational, and potentially employee-related information was taken. The listing appeared on March 13, 2025, and follows the group’s standard practice of publishing proof of compromise when ransom demands are not met.

Why This Matters for You and Your Family

When a government-linked organization like Nuclep suffers a breach, the ripple effects reach ordinary people. Employees, contractors, suppliers, and even families whose personal details sit in vendor files can find their information exposed. Internal files often contain spreadsheets with names, contact details, national identification numbers, or email addresses that attackers can sell or weaponize. For you and your family, this means another vector for phishing, identity theft, or harassment that started from a breach you had no control over.

Credential leaks frequently accompany ransomware incidents. If any reused passwords or email addresses from Nuclep appear in the dump, your other accounts become immediate targets.
