When 24-year-old freelance hacker Ava Lin broke into the classified system of the National Security Cyber Bureau (NSCB) to test its defenses for a client, she expected to find encrypted data packets, firewalls, or maybe even hidden surveillance tools.

Curious, she copied it and booted up her private server to decrypt it, unaware the NSCB would notice their breach within minutes.
