in the realm of the hackers

In The Realm of the Hackers is a 2003 Australian documentary directed by Kevin Anderson about the prominent hacker community, centered in Melbourne, Australia in the late 80’s to early 1990. The storyline is centered around the Australian teenagers going by the hacker names “Electron” and “Phoenix”, who were members of an elite computer hacking group called The Realm and hacked into some of the most secure computer networks in the world, including those of the US Naval Research Laboratory, Lawrence Livermore National Laboratory, a government lab charged with the security of the US nuclear stockpile, and NASA.
