A town’s failed oversight left its water system vulnerable after a disgruntled former employee exploited a dormant account. While the incident didn’t involve a full-scale hack, the mistake highlights the risks of neglecting routine security checks. The case centers on a person who once held critical access rights and later used their work credentials for unrelated purposes. A former employee’s email address was compromised, revealing an open door to potential misuse. This underscores the importance of thorough audits and credential management in preventing similar incidents. In my view, every forgotten user is a ticking time bomb—every overlooked detail contributes to future vulnerabilities. To prevent such mistakes, cities should implement mandatory periodic audits and ensure that employees’ credentials remain distinct from non-essential services.
