ProMantra Data Breach? Lawyers Investigate Hackers' Claims

Attorneys working with ClassAction.org are looking into whether a class action lawsuit can be filed in light of reports of a possible ProMantra data breach.

As part of their investigation, they need to hear from individuals who believe their information may have been put at risk , including current and former ProMantra employees, as well as the patients of its healthcare clients.

Reports Emerge of Possible ProMantra Security Breach

ProMantra, a New Jersey-based healthcare revenue cycle management and support company, may have suffered a data breach.

According to a September 17, 2026 post on dark web monitoring site Ransomware.live , hacker group Metaencryptor was behind the suspected attack, which was estimated to have occurred the same day the post was made.

HookPhish , another cybersecurity blog, similarly reported that Metaencryptor claimed to be responsible for an attack on ProMantra.

At the time this post was made, no additional information was available the scope or nature of the unconfirmed ProMantra data breach.

If you're affiliated with ProMantra and suspect your information could have been put at risk, attorneys want to hear from you. You may be able to start a class action lawsuit to recover compensation for loss of privacy, lost time, out-of-pocket costs, and more.

A successful case could also force ProMantra to ensure they take proper steps to protect the information they were entrusted with.
