Dae Soo "Doris" Min was an outside contractor for CTU. She was brought in because of her outstanding reverse-engineering skills and abilities to hack Korean software. She had just turned sixteen when she visited the WFORE (Working Forum of Reverse Engineering) and was offered a job. She was first brought in for help with the Korean missile-launcher computer systems during the events of Operation Hell Gate. She was also brought in for her expertise in mayhemware and other technology during the absence of Milo Pressman in Trojan Horse. She appeared to be a full-time CTU employee in Vanishing Point.
