Kenneth J. Soona (played by Bernie Coulson) was an anarchist computer hacker known as the Thinker. He was an associate of the Lone Gunmen and impressed even them with his hacking skills. He first assisted Mulder when he downloaded Dana Scully's medical files following her return. In 1995, Soona hacked into secret MJ documents and recorded them on a DAT tape. The documents contained details on everything since the Roswell incident. The Cigarette Smoking Man was sent by the Syndicate to retrieve the MJ documents. Soona met Mulder to give him the tapes, but Soona's identity was found out and he was later killed and the tape was returned.
