PK PINHÃO & KOIFFMAN ATTORNEYS AT LAW Listed by incransom Ransomware Group

On January 30, 2026, Brazilian law firm PK Pinhao & Koiffman Advogados was listed on the leak site of the ransomware group Incransom after the firm failed to meet an extortion deadline. The attackers claim to have exfiltrated roughly 100GB of internal files containing confidential documents and client data.

What Public Reporting Shows

Public reporting indicates the firm, which specializes in technology, innovation, family business planning, digital law, contracts, regulatory compliance, telecommunications, finance, blockchain, and fintech, had internal systems compromised in a ransomware incident. The group posted proof of the breach on its onion site, listing the law firm and stating that confidential documents and clients data had been taken. No exact number of affected individuals has been confirmed, and the full scope of exposed records remains unclear from available reporting.

The leak page describes the data as including sensitive client information that would normally be protected under attorney-client privilege. Ransomware.live mirrors state the posting date as January 30, 2026, and note that the actors provided a sample of the stolen material before threatening full publication.

Why This Matters for You and Your Family

When a law firm that handles family business planning, estate matters, and sensitive personal records is breached, the information at risk often includes details that directly affect ordinary people and their households. If you or your family have ever been clients, your names, addresses, financial arrangements, legal documents, or correspondence could now sit in an attacker’s archive.

Client data from such firms frequently contains dates of birth, tax identifiers, bank account numbers, family member names, and copies of identification documents. Once that material leaves the firm’s control, it can be sold, traded, or used to build profiles that make identity theft, fraudulent loan applications, or targeted scams far easier. For many families the breach represents a permanent loss of confidentiality with no practical way to retract the information.

The Doxxing and Identity-Chain Implications

Legal documents often link multiple pieces of personal information that attackers can chain together. A single leaked email or phone number can be correlated with social-media handles, children’s names, school records, or gaming usernames. These connections allow criminals to move from one account to another, turning a single breach into long-term harassment or financial fraud.

Credential leaks like this one frequently cascade into account takeovers. If passwords or security questions appear in the stolen files, anyone reusing those credentials across email, banking, or online services becomes vulnerable. Gaming accounts belonging to children are especially attractive targets because they often share the same family email or phone number listed in the firm’s client records.

Incransom’s Publicly Known Track Record

Public reporting attributes Incransom with emerging in late 2024 as a double-extortion ransomware operation. The group is known for targeting mid-sized businesses, stealing data before encrypting systems, and then pressuring victims through both data leaks and operational disruption. Notable prior victims have included healthcare providers, manufacturing companies, and professional service firms across Latin America and Europe.

Their typical playbook involves initial access through phishing or exploited remote desktop services, followed by exfiltration of sensitive folders over several weeks. After encryption they publish samples on their leak site and set short payment deadlines, threatening to release the full archive if demands are not met. Available reporting describes their extortion style as aggressive but somewhat opportunistic, focusing on volume of data rather than highly sophisticated targeting.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, handles, and real-world identity so you can see exactly what chains back to this claimed breach.
• Rotate any password you ever used at the law firm anywhere else it appears, then enable two-factor authentication through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information surfaces you learn within hours instead of months.
• Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts commonly chained to the same family details.
• Let remediation specialists handle takedown requests and broker removals for you while you focus on securing accounts and watching for suspicious activity.

The incident shows that even professional firms entrusted with your most private matters can lose control of that information in a single afternoon.
