ProMantra Investigates Alleged Data Breach Linked to Metaencryptor Hacker Group
On September 17, 2026, reports emerged of a potential data breach at ProMantra, a New Jersey-based healthcare revenue cycle management company. The suspected incident, allegedly carried out by the hacker group Metaencryptor, was first noted on the dark web monitoring site Ransomware.live and later corroborated by cybersecurity sources.
Attorneys working with ClassAction.org are investigating whether a class action lawsuit can be filed on behalf of affected individuals, including current and former ProMantra employees and patients of its healthcare clients. The scope and nature of the breach remain unconfirmed, but legal representatives are seeking individuals who believe their data may have been exposed.
Metaencryptor claimed responsibility for the attack, which reportedly occurred on the same day the breach was publicized. If successful, a class action could seek compensation for affected parties, covering damages such as loss of privacy, out-of-pocket costs, and other related harms.
ProMantra has not yet released official details on the incident, and investigations are ongoing. The case highlights growing concerns over cybersecurity risks in the healthcare sector.
