Jack Henry Addresses Cybersecurity Incident Impacting Fewer Than 10 Clients
Jack Henry & Associates (Nasdaq: JKHY) reported detecting a cybersecurity incident in its internal, non-production corporate environment. The company emphasized that no client-facing systems or daily operations were affected and remained secure throughout the event. A sophisticated vishing attack by threat actor ShinyHunters initiated the breach, but Jack Henry's security controls quickly contained it. The firm confirmed fewer than 10 clients had their personally identifiable information (PII) impacted. All over 7,200 of its financial institution clients were notified about the incident and are being directly supported by company teams. Affected institutions will receive two years of credit monitoring for accountholders. Jack Henry is collaborating with a third-party cyber forensics firm and federal law enforcement to investigate further. The breach involved an extortion attempt, but no ransom was paid. The company stated the incident has not had material financial impact.
