On December 22, 2022, the ransomware group Clop added empirical-research.com to its public leak site, claiming that internal files had been exfiltrated from the company during a ransomware attack. Anyone whose personal or professional information passed through Empirical Research is now at risk of exposure, including researchers, study participants, clients, and employees whose data may have been stored in the compromised systems.

You can’t unleak data. You can take away what it’s worth.
A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

Reported Details from the Listing
The Clop leak site listing states that internal files were exfiltrated in a ransomware attack but does not disclose the volume of data taken, the exact types of records involved, or the number of people affected. The disclosure indicates that the company was listed after failing to meet the group's demands, with the sample data published as proof of compromise. No specific victim count or detailed inventory of exposed information appears on the leak page itself. The incident follows the group's standard pattern of exfiltration before encryption, with the listing serving as an extortion pressure point.
Why This Matters for You and Your Family
When a research firm like Empirical Research loses control of internal files, the information can include names, contact details, dates of birth, addresses, and study-related records that tie directly to real people. Internal files exfiltrated in such attacks often contain spreadsheets, contracts, consent forms, or payment records that reveal far more than a simple email address. If your family participated in any research studies managed by this organization, or if you or a household member worked with them professionally, those details may now be in the hands of extortionists. The breach notification does not quantify affected records, leaving every individual to assume their information could be part of the set until proven otherwise.
The Doxxing and Identity-Chain Risks
Exfiltrated research data frequently links email addresses, phone numbers, physical addresses, and participant identifiers in ways that allow attackers to build complete identity profiles. These chains can connect to gaming accounts, social-media handles, and family relationships, turning a single breach into repeated targeting. Credential leaks of this nature regularly cascade into account takeovers, especially for gaming platforms used by children and teenagers. Once an attacker maps one legitimate email or phone number to a child’s Roblox, Discord, or Fortnite account, the entire household becomes vulnerable to social engineering and further doxxing. The public nature of the Clop leak site means any interested party, criminal or otherwise, can download the samples and begin stitching together these connections.
