By using a tool often associated with bypassing hardware bans in gaming, Leo had saved a decade of medical records. He deleted the .exe from his thumb drive, packed his bag, and handed the keys back to the head nurse. 💡 Key Takeaways

Leo’s client was a non-profit clinic. Their old patient management system had crashed when a primary drive failed.
