Attorneys at Almeida Law Group are investigating whether a class action lawsuit can be filed on behalf of individuals affected by a possible Hologic, Inc. data breach. According to dark web monitoring sources, a hacker group calling itself metaencryptor claimed responsibility for a cyberattack on Hologic, Inc. in a post first observed in September 2026, alleging it had gained access to internal company systems. As of this writing, Hologic, Inc. has not issued a public confirmation of the incident, and the exact scope of any exposed data remains unknown. If you believe you were affected, contact Almeida Law Group.

What Happened?
Hologic, Inc. was listed in a ransomware leak-site allegation reported by Ransomware.live. According to that dark web monitoring source, the ransomware group MetaEncryptor claimed Hologic as a victim, with the claim first observed on September 7th, 2026. No breach date, discovery date, or confirmed data types have been reported. No independent corroborating source has been found for this specific MetaEncryptor claim, and Hologic has not publicly issued any breach notification or confirmation tied to it.
This is not the first time Hologic has appeared in ransomware leak-site allegations in 2026. The group known as 0apt claimed Hologic as a victim on February 4th, 2026, and the group Redact claimed Hologic on June 28th, 2026, alleging exfiltration of 98 GB of data — though that figure is an attacker-side assertion only. None of these prior claims have been independently confirmed by Hologic. It is unclear whether these represent separate intrusions, the same data being reclaimed under different group names, or false claims. Separately, a proposed class action lawsuit — Cameron v. Hologic, Inc. — was filed in Massachusetts federal court alleging that sensitive personal data held by Hologic was exposed in a cyberattack, as reported by Law360 around July 2026; it is unclear which specific incident or claim the lawsuit relates to. MetaEncryptor is a ransomware group linked by researchers to the SFile ransomware family and suspected of later rebranding as the LostTrust ransomware operation; it uses a double-extortion model combining encryption with data exfiltration threats.
