Centers Laboratory Data Breach Affects 542,377 People — Should You Be Worried?

A Centers Laboratory data breach caused personal and medical information tied to more than half a million people to be leaked. Here’s why it matters and how to stay safer.

What Happened at Centers Laboratory?

According to SecurityWeek, Centers Laboratory — a New Jersey healthcare testing provider — reported a data breach affecting 542,377 people.

The company discovered the intrusion in August 2025. Criminals accessed its systems between August 9 and August 14.

During that period, personal and protected health information was copied from the company’s systems.

The WorldLeaks extortion group later claimed responsibility. The group said it stole 720 GB of data across more than 1.6 million files.

Stolen medical and identity details can support phishing emails, impersonation attempts, and identity fraud long after the original breach.

Your information may also have been leaked through another healthcare provider, employer, retailer, or online service without your knowledge.

Who Was Affected and What Data Was Leaked?

The breach affected people whose information was stored by Centers Laboratory for healthcare testing and related services.

The leaked information included:

  • Names
  • Dates of birth
  • Social Security numbers
  • Driver’s license details
  • State identification numbers
  • Passport numbers
  • Health insurance information
  • Medical information

The company did not say whether every affected person had every type of information taken.

This information can help criminals send convincing phishing messages or commit identity theft. Phishing means fake messages designed to steal information or money.
