The FBI and Facebook's security team launched a joint investigation, determined to track down the hacker. Alex, realizing the gravity of their actions, began to feel the weight of their newfound notoriety.

Feeling a mix of excitement and guilt, Alex decided to leave a small message on Mark's wall: "Nice try, but you're not as secure as you think." The message was meant to be a lighthearted poke, but it quickly sparked a media frenzy.

Meanwhile, Alex was ecstatic. Their reputation as a skilled hacker had spread like wildfire, and they became an overnight sensation in the cybersecurity community. But as the attention grew, so did the scrutiny.
