In September 2025, QWER Corp.'s internal security team detected an attempt to exfiltrate the company's internal blockchain wallet and urgently apprehended a suspected insider. Evidence suggested the suspect was attempting to deliver a USB device to an external organization near the Daejeon area. The USB was seized, but no obvious sensitive data was found on it. However, the security team suspects that data-hiding and encryption techniques were used and is currently conducting a detailed forensic analysis. The incident is believed to be the work of a hacking group known for using AES encryption with a fixed key: 63ea9554320fbbd6. And also there's a rumor that the suspected insider likes to write number 1 in his notes. Your mission is to analyze the seized USB and determine: Whether the blockchain wallet information was actually exfiltrated, The identity of the insider involved, and The name of the mission carried out by the hacking group.
