This happened in at Arnold Air Force Base
FBI communications may also have been compromised by an engineer working on Tennessee Air Force base, search warrant reveals.
The article sure makes it sounds like it was just CPS and system keys. Regardless it's pretty weird, it sounds like he was just taking it home for personal use (which itself is pretty strange).Being the fbi is mainly secure he must have had a kvl loader or access to the exact keys to compromise them or other sensitive data.
According to the warrant, “witnesses and co-workers” told investigators that the suspect “sold radios and radio equipment, worked odd hours, was arrogant, frequently lied, displayed inappropriate workplace behavior and sexual harassment, had financial problems, and possessed [Arnold Air Force Base land mobile radio] equipment.” A colleague had twice reported him because of “insider threat indicators” and unauthorized possession of Air Force equipment, investigators said.
