Saydel Independent School District: Insider Threat via Offboarding Failure
A former Senior IT Support Specialist, Ezekiel Dean Potter, executed an 18-month cyber sabotage campaign against the Saydel Independent School District after his termination in April 2023. The attacker leveraged retained administrative credentials that were not revoked during the offboarding process to gain unauthorized access to district systems. This persistence enabled the deletion of critical user accounts and the disruption of classroom operational telemetry. The breach resulted in tens of thousands of dollars in financial losses and culminated in a 21-month federal prison sentence following a forensic audit of authentication logs and system telemetry.
