TRONTONICS.

In the late 1990s, several computer hackers attempted to gain access to files in the computer network at the Pentagon. The incidents, which were dubbed Solar Sunrise, were regarded as a dress rehearsal for a later and more malicious cyber-attack, and stimulated a revamping of the military's computer defenses. In another example, computer hackers were able to gain access to patient files at the Indiana University School of Medicine in February 2003.
