The 2025 Prison Hack: Stolen Credentials & Fraudulent Credits
He was already in prison… so he hacked the prison instead.
In 2025, an inmate at Târgu Jiu Penitentiary in Romania pulled off something that sounds like a movie plot but was very real. Aurel Z., a 36-year-old serving nearly ten years for financial fraud, managed to break into the national prison IT system from inside his cell.
Using stolen administrator credentials that once belonged to a former prison director, he accessed the system through an inmate information kiosk starting August 8. From there, he quietly began rewriting reality for other inmates.
He altered sentence reduction records known as “earning days,” tampered with personal account balances, erased purchase histories to trigger refunds, and even unlocked access to adult content on restricted terminals. At least fifteen inmates across multiple facilities were affected, including prisons in Timișoara and Pelendava.
The breach went far deeper than small favors. Investigators later found that the system exposed sensitive personal data like phone numbers, disciplinary histories, and private records. Accounting staff eventually noticed something was very wrong when unexplained transfers appeared, some totaling up to five million lei, roughly $1.1 million.
That discovery triggered a nationwide alarm.
The National Penitentiary Administration launched an internal probe alongside a criminal investigation. Staff faced disciplinary action. Keyboards were removed from inmate kiosks across facilities. Officials confirmed that no one was released early due to the tampering, but the damage was already done.
The incident exposed serious vulnerabilities in Romania’s prison infrastructure. A system designed to monitor inmates had been turned against itself, not by an outside hacker, but by someone already behind bars.
It’s unsettling for a simple reason.
If someone serving time can quietly access and manipulate a national corrections system, the real sentence might belong to the system that failed to stop him.
