Stoll trapped Hess by creating records of a bogus military project conducted on LBL computers; according to "The Cuckoo's Egg", he and his girlfriend conceived this plan while showering, giving it the unofficial name of "Operation Showerhead". While the bogus information was convincing, the primary goal was simply to keep the hacker connected long enough to trace his connection, and with the hope that the hacker might send a written request for further information listed as available in hard copy. This simple technique worked: a request for the additional information was received from a Pittsburgh, Pennsylvania address.
