On February 12, 2023, the ransomware group LockBit3 listed mrkpc.com on its leak site, claiming that the Dallas-based law firm Mullin, P.C. had been hit by a ransomware attack in which internal files were allegedly exfiltrated. The disclosure indicates that data was taken but does not specify the volume of records affected or the exact nature of every document involved. Anyone whose information passed through the firm — clients, business partners, or employees — may now face heightened exposure.

Details from the Leak Site
The primary disclosure on the LockBit3 leak site states that Mullin, P.C. suffered a ransomware incident and that attackers successfully exfiltrated internal files. No specific victim count is provided, and the listing does not detail the precise data types beyond claiming that internal files were taken. The firm, which specializes in franchising, commercial litigation, and international representation, has not yet released a public notification quantifying impact. Public reporting on LockBit3 incidents shows that when exact figures are omitted from the initial listing, the group often releases sample files as proof.
Why This Matters for You and Your Family
If you or your family have ever been represented by Mullin, P.C., your sensitive legal documents, correspondence, financial details, or personally identifiable information could be in the hands of criminals. Internal files exfiltrated in ransomware attacks frequently include contracts, client intake forms, Social Security numbers, addresses, and payment records. Even if you are not a current client, shared vendors or counterparties in franchise deals may have had their data entangled in the same systems. this claimed breach places ordinary people at risk of identity theft, financial fraud, and targeted scams that begin with information reportedly stolen from trusted professional advisers.
Doxxing and Identity-Chain Risks
Legal firm breaches create long identity chains because client files often link email addresses, phone numbers, home addresses, business affiliations, and family details in a single record. Attackers and subsequent data brokers can map these connections to build comprehensive profiles. A leaked email from one case can be cross-referenced with credentials appearing in other breaches, leading to account takeovers. Credential leaks like this one frequently cascade into gaming accounts belonging to you or your children, especially when family email addresses were used to register those accounts. The result is doxxing that can expose home addresses, children’s names, and daily routines to harassment or further extortion.
