Jack Henry Reports Cybersecurity Breach via Vishing Attack

The breach originated from a sophisticated vishing attack orchestrated by the threat actor known as ShinyHunters. Jack Henry security protocols identified the unauthorized activity, allowing the company to isolate affected systems and contain the threat before it reached client-facing platforms or core processing services. No system outages occurred during the event, and the company maintains that the incident holds no material financial impact.

To address the fallout, Jack Henry has notified its network of more than 7,200 clients and is providing two years of credit monitoring services for the affected accountholders. The firm has retained an independent third-party forensics team to assist with the investigation and continues to collaborate with federal law enforcement. By refusing to engage with the extortion demands, the company aims to uphold its established security response framework while maintaining transparency regarding the compromise of its internal corporate environment.
