Washington DC

THE Pentagon is under siege from computer hackers, according to a study
from the US General Accounting Office (GAO). The report warns that every year
there are an estimated 250 000 attempts to gain unauthorised access to military
computers. An unknown number of these attempts is successful, it says.

In its search for intruders, the Pentagon鈥檚 own team of hackers has
successfully hacked into defence computers in about 65 per cent of the 38 000
attempts they have made since 1992. Only about 4 per cent of these friendly
attacks were detected by the Pentagon鈥檚 computer operators, and even fewer were
reported to security officials, says the study.

鈥淗ackers have stolen and destroyed sensitive data and software. They have
installed `back doors鈥� into computer systems which allow them to surreptitiously
regain entry into sensitive defence systems,鈥� says Jack Brock, an official at
the GAO. 鈥淭hey have `crashed鈥� entire systems and networks, denying computer
service to authorised users and preventing defence personnel from performing
their duties.鈥�

Brock told a Congressional committee that a 16-year-old British hacker going
by the name of 鈥淒atastream cowboy鈥� and working with an accomplice called 鈥淜uji鈥�
attacked computers at the Air Force鈥檚 Rome Laboratory in New York more than 150
times in 1994. They stole research data relating to the attack instructions that
would be given to US warplanes in battle. The British boy is still awaiting
prosecution in Britain for allegedly stealing telephone services, but Kuji has
never been found. 鈥淐onsequently, no one knows what happened to the data stolen
from Rome lab,鈥� says Brock.
