Penn-Harris-Madison (PHM) School Corporation in Mishawaka was targeted by a ransomware attack, leading to a network breach detected on a Monday morning. As a precautionary measure, the district shut down all network-connected desktop computers, though Chromebooks, laptops, mobile devices, and cloud-based applications remained operational. The attack’s scope is still under investigation by cybersecurity experts, with no confirmation yet on whether data was compromised. The incident disrupted administrative and educational operations, forcing reliance on alternative devices and systems. The district emphasized that the breach was limited to the network, but the potential exposure of sensitive data—such as student, staff, or financial records—remains unclear. Recovery efforts and forensic analysis are ongoing, with no immediate details on ransom demands or data exfiltration. The attack highlights vulnerabilities in school district cybersecurity, raising concerns about operational continuity and data protection.
