   Trax continued to refine his ability to manipulate both the telephone

   and the exchange. He took his own telephone apart, piece by piece,

   countless times, fiddling with the parts until he understood exactly

   how it worked. Within months, he was able to do far more than just

   make free phone calls. He could, for instance, make a line trace think

   that he had come from a specific telephone number.


   He and Mendax joked that if they called a `hot' site they would use

   Trax's technique to send the line trace--and the bill--back to one

   very special number. The one belonging to the AFP's Computer Crime

   Unit in Melbourne.


   All three IS hackers suspected the AFP was close on their heels.

   Roving through the Canberra-based computer system belonging to the man

   who essentially ran the Internet in Australia, Geoff Huston, they

   watched the combined efforts of police and the Australian Academic and

   Research Network (AARNET) to trace them.


   Craig Warren of Deakin University had written to Huston, AARNET

   technical manager, about hacker attacks on university systems. Huston

   had forwarded a copy of the letter to Peter Elford, who assisted

   Huston in managing AARNET. The hackers broke into Huston's system and

   also read the letter:
