He considered how to route the attack. He could go through a few diverters and other leapfrog devices to cover his trail, thus hitting the company's system from a completely separate source. The advantage of this route was anonymity. If the admin managed to detect his entry, Anthrax would only lose access to the phone company's system, not to System X. Alternatively, if he went in to the company through the gateway and System X, he risked alarms being raised at all three sites. However, his sniffer showed so much traffic running on this route, he might simply disappear in the flow. The established path was obviously there for a reason. One more person logging into the gateway through System X and then into the company's machine would not raise suspicions. He chose to go through System X. Anthrax logged into the company using a sniffed username and password. Trying the load-module bug again, he got root on the system and installed his own login patch. The company's system looked far more normal than System X. A few hundred users. Lots of email, far too much to read. He ran a few key word searches on all the email, trying to piece together a better picture of the project being developed on System X. The company did plenty of defence work, mostly in telecommunications. Different divisions of the company seemed to be working on different segments of the project. Anthrax searched through people's home directories, but nothing looked very interesting because he couldn't get a handle on the whole project. People were all developing different modules of the project and, without a centralised overview, the pieces didn't mean much. He did find a group of binary files--types of programs--but he had no idea what they were for. The only real way to find out what they did was to take them for a test drive. He ran a few binaries. They didn't appear to do anything. He ran a few more. Again, nothing. He kept running them, one after another. Still no results. All he received was error messages. The binaries seemed to need a monitor which could display graphics. They used XII, a graphical display common on Unix systems. Anthrax's inexpensive home computer didn't have that sort of graphical display operating system. He could still run the binaries by telling System X to run them on one of its local terminals, but he wouldn't be able to see the output on his home computer. More importantly, it was a risky course of action. What if someone happened to be sitting at the terminal where he chose to run the binary? The game would be up.
