BioResearch Listed by Deadlock Ransomware Group

On July 25, 2026, Polish clinical research organization BioResearch Group was listed on the leak site of the Deadlock Ransomware Group. The entry confirms that internal files were exfiltrated during a ransomware attack on the Warsaw-based company, which specializes in Phase I, First-In-Human, SAD, MAD, and bioequivalence studies for pharmaceutical sponsors and contract research organizations.

Reported Details from the Listing

The Deadlock leak site states that data was stolen from BioResearch Group and is now published for anyone to download. The primary disclosure does not quantify the number of records affected, list specific data types beyond “internal files,” or reveal whether patient records, contracts, or financial documents were included. It also does not state the ransom demand or whether any payment deadline has passed. The listing simply confirms successful exfiltration following a ransomware deployment, consistent with Deadlock’s standard publication method.

Why This Matters for You and Your Family

If you or any member of your family has participated in an early-phase clinical trial at BioResearch or its affiliated clinic and laboratory, your personal information and medical history may now sit in an openly downloadable archive. Even if you were never a trial participant, employees, contractors, and their families are also at risk. Names, contact details, dates of birth, national identification numbers, banking information, and correspondence that reference family members can all appear in research organization datasets. Once these files circulate on criminal forums, they become permanent fuel for identity theft, loan fraud, and targeted scams against you and your household.

Doxxing and Identity-Chain Risks

Clinical research records frequently link real identities to email addresses, phone numbers, physical addresses, and sometimes passport or insurance details. These records create high-confidence identity chains that criminals can follow across future breaches. A single leaked trial consent form can expose not only the participant but also listed emergency contacts and household members. Public reporting shows that such chains are routinely used to locate social-media profiles, children’s gaming accounts, and family members’ employment records. The exposure therefore extends far beyond the initial breach and can trigger cascading account takeovers months or years later.

Deadlock Ransomware Group Track Record

Public reporting attributes the emergence of Deadlock to late 2024. The group has since targeted healthcare, technology, and professional-services organizations across Europe and North America. Notable prior victims include mid-sized hospitals, laboratory networks, and research contractors. Deadlock’s typical playbook involves initial access through compromised remote desktop or VPN credentials, followed by lateral movement, data exfiltration, and deployment of ransomware. After encryption they publish a sample of stolen files on their leak site and demand payment to prevent full release. They rarely negotiate publicly and often follow through with gradual data dumps when victims remain silent.

What to do

• Run a DoxxScan to map every link between your email addresses, phone numbers, usernames, and real-world identity so you can see exactly what this breach has exposed.
• Rotate any password you used at BioResearch or related research portals anywhere it has been reused, and switch to 2FA via an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 15.4B+ breach records and 100+ platforms so the next time your information appears it is caught within hours, not months.
• Cover the entire household — DoxxScan family coverage includes dependents and children’s gaming accounts that often chain back to the same leaked address or parent email.
• Let DoxxScan remediation specialists handle data-broker takedown requests and opt-out processes that would otherwise consume hundreds of hours of your time.

The BioResearch listing is a reminder that clinical-trial participants and their families now sit in the same high-risk category as employees of banks and government agencies. Protecting yourself requires more than changing a password; it demands ongoing visibility into how your identity is being recombined across criminal marketplaces. DoxxScan by GalaxyWarden delivers that visibility through continuous monitoring across 15.4 billion breach records and over 100 platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that explicitly protects children’s gaming accounts from the same credential-stuffing and doxxing chains that follow incidents like this one.
