On June 06, 2023, Brazilian architectural and engineering firm progen.com.br appeared on the LockBit 3.0 ransomware leak site. The listing states that internal files were exfiltrated during a ransomware attack; the exact number of affected individuals remains unknown because neither the leak-site posting nor any subsequent company notification has disclosed record counts or specific data types beyond the broad category of internal files.

Primary Disclosure Details
The LockBit 3.0 leak page explicitly lists progen.com.br and claims successful data theft following a ransomware deployment. It includes a brief company description in Portuguese noting that the firm has completed more than 5,000 projects for major national and international clients over 35 years. The posting does not detail which folders or file types were taken, nor does it publish sample data. A countdown timer typical of the group’s extortion process was displayed, after which the threat actors usually begin releasing stolen material in batches if demands are unmet. Public reporting on LockBit 3.0 indicates the group continues to favor double-extortion tactics: encryption of victim systems paired with threats to publish sensitive exfiltrated documents.
Why This Matters for You and Your Family
When a company that has worked with large clients for decades suffers a breach, the ripple effects frequently reach private individuals. Project files, contracts, invoices, and correspondence often contain names, addresses, contact details, tax identifiers, and sometimes financial information of clients, vendors, and employees. If your family has ever hired an architecture, engineering, or construction firm in Brazil — or if you work for one of the “maiores players” referenced in the listing — your personal data may now sit in an attacker-controlled archive. Even without exact victim counts, the internal files exfiltrated label signals broad exposure that can be repurposed for identity theft, phishing, or targeted scams months or years later.
Doxxing and Identity-Chain Risks
Stolen internal documents rarely exist in isolation. They often link email addresses, phone numbers, project codes, and physical addresses, creating chains that tie online handles to real-world identities. Threat actors and data brokers routinely combine such leaks with information from other breaches, turning a single corporate incident into long-term doxxing fuel. Once an attacker maps one household member, the entire family becomes easier to target through social engineering or SIM-swapping attacks.
