Avantic Medical Lab Ransomware Attack | Data Breach Lawyers

The data breach lawyers at The Lyon Firm are investigating a hacking incident reported by Breachsense that may have impacted a large number of individuals. On July 3, 2025, an alleged ransomware attack by the Everest group was uncovered on the dark web, targeting Avantic Medical Lab, a clinical laboratory in Edison, New Jersey.

This cybersecurity breach has not been confirmed by Avantic yet, however, if it did occur, it may have exposed your personal and health information, putting you at serious risk. If you’ve ever used Avantic’s services, it is prudent to act now to begin to consider your legal options. Our law firm is launching a class action investigation on behalf of impacted individuals nationwide.

What Happened at Avantic Medical Lab?

The Everest group’s alleged attack potentially compromised a mix of personally identifiable information (PII) and protected health information (PHI). This could include details like your name, date of birth, address, phone number, Social Security number, medical records, health insurance details, diagnostic test results, and payment information. The theft of a combination of PII and PHI can be a nightmare for impacted clients, amplifying the risk of identity theft, medical fraud, and financial loss.

Ransomware attacks like this are a serious threat, encrypting victims’ data and demanding payment for its release. The risks are substantial: financial losses stem from ransom payments—often with no guarantee of data recovery. Permanent data loss looms if backups fail. Many attacks now result in data breaches, with stolen information exposed unless ransom demands are met, risking legal and privacy issues.
