In times of war, the military doesn't want to be dependent on the civilian telephone system. Even in times of peace, voice communications between military staff are more secure if they don't talk on an exchange used by civilians. For this and a variety of other reasons, the military have separate telephone networks, just as they have separate networks for their data communications. These networks operate like a normal network and in some cases can communicate to the outside world by connecting through their own exchanges to civilian ones.

When Anthrax got the word from the expert hacker, he made up his mind quickly. Up went the sniffer. System X was getting more interesting by the hour and he didn't want to miss a precious minute in the information gathering game when it came to this system.

The sniffer, a well-used program rumoured to be written by a Sydney-based Unix hacker called Rockstar, sat on System X under an innocuous name, silently tracking everyone who logged in and out of the system. It recorded the first 128 characters of every telnet connection that went across the ethernet network cable to which System X was attached. Those 128 bytes included the username and the pa.s.swords people used to log in. Sniffers were effective, but they needed time. Usually, they grew like an embryo in a healthy womb, slowly but steadily.

Anthrax resolved to return to System X in twelve hours to check on the baby.

'Why are you two watching those n.i.g.g.e.r video clips?'

It was an offensive question, but not atypical for Anthrax's father.

He often breezed through the house, leaving a trail of disruption in his wake.

Soon, however, Anthrax began eroding his father's authority. He discovered his father's secrets hidden on the Commodore 64 computer.

Letters--lots of them--to his family in England. Vicious, racist, horrid letters telling how his wife was stupid. How she had to be told how to do everything, like a typical Indian. How he regretted marrying her. There were other matters too, things unpleasant to discuss.

Anthrax confronted his father, who denied the allegations at first, then finally told Anthrax to keep his mouth shut and mind his own business. But Anthrax told his mother. Tensions erupted and, for a time, Anthrax's parents saw a marriage counsellor.

But his father did not give up writing the letters. He put a pa.s.sword protection program on the word processor to keep his son out of his business. It was a futile effort. His father had chosen the wrong medium to record his indiscretions.

Anthrax showed his mother the new letters and continued to confront his father. When the tension in the house grew, Anthrax would escape with his friends. One night they were at a nightclub when someone started taunting Anthrax, calling him 'curry muncher' and worse.

That was it. The anger which had been simmering below the surface for so long exploded as Anthrax violently attacked his taunter, hitting, kicking and punching him, using the tai kwon do combinations he had been learning. There was blood and it felt good. Vengeance tasted sweet.

After that incident, Anthrax often lashed out violently. He was out of control and it sometimes scared him. However, at times he went looking for trouble. Once he tracked down a particularly seedy character who had tried to rape one of his girlfriends. Anthrax pulled a knife on the guy, but the incident had little to do with the girl. The thing that made him angry was the disrespect. This guy knew the girl was with Anthrax. The attempted rape was like spitting in his face.

Perhaps that's what appealed to Anthrax about Islam--the importance of respect. At sixteen he found Islam and it changed his life. He discovered the Qu'raan in the school library while researching an a.s.signment on religion. About the same time, he began listening to a lot of rap music. More than half the American rappers in his music collection were Muslim, and many sang about the Nation of Islam and the sect's charismatic leader, Minister Louis Farrakhan. Their songs described the injustices whites inflicted on blacks. They told blacks to demand respect.

Anthrax found a magazine article about Farrakhan and began reading books like the Autobiography of Malcolm X. Then he rang up the Nation of Islam head office in Chicago and asked them to send some information. The Final Call, the NOI newsletter, arrived one day, followed by other literature which began appearing around Anthrax's home. Under the TV guide. On the coffee table. Amid the pile of newspapers. On top of his computer. Anthrax often took time to read articles aloud to his mother while she did housework.

In the middle of 1990, when Anthrax was in year 11, his father suggested the boy attend Catholic boarding school in Melbourne. The school was inexpensive and the family could sc.r.a.pe and save to pay the fees. Anthrax disliked the idea, but his father insisted.

Anthrax and his new school proved a bad match. The school thought he asked too many questions, and Anthrax thought the school answered too few of them. The hypocrisy of the Catholic church riled Anthrax and pushed him further into the arms of NOI. How could he respect an inst.i.tution which had sanctioned slavery as a righteous and progressive method of converting people? The school and Anthrax parted on less than friendly terms after just one semester.

The Catholic school intensified a feeling of inferiority Anthrax had felt for many years. He was an outsider. The wrong colour, the wrong size, too intelligent for his school. Yet, NOI's Minister Farrakhan told him that he wasn't inferior at all. 'I know that you have been discriminated against because of your colour,' Farrakhan told Anthrax from the tape player. 'Let me tell you why. Let me tell you about the origins of the white race and how they were put on this earth to do evil. They have shown themselves to be nothing but an enemy of the East. Non-whites are the original people of the earth.'

Anthrax found some deep veins of truth in NOI's teachings. Interracial marriages don't work. A white man marries a non-white woman because he wants a slave, not because he loves and respects her. Islam respects women in more meaningful ways than Western religions. Perhaps it wasn't the type of respect that Western men were used to giving women, but he had seen that kind of respect in his own home and he didn't think much of it.

Anthrax read the words of the Honourable Elijah Muhammad, founder of NOI: 'The enemy does not have to be a real devil. He could be your father, mother, brother, husband, wife or children. Many times they're in your own household. Today is the great time of separation of the righteous Muslim and the wicked white race.' Anthrax looked inside his own household and saw what seemed to be a devil. A white devil.

NOI fed Anthrax's mind. He followed up the lists of literature included in every issue of The Final Call. Books like Black Athena by Martin Bernel and Deterring Democracy by Noam Chomsky had common themes of conspiracy and oppression by the haves against the have-nots. Anthrax read them all.

The transformation of Anthrax occurred over a period of six months. He didn't talk about it much with his parents. It was a private matter.

But his mother later told him his adoption of the religion didn't surprise her. His great-grandfather had been a Muslim scholar and cleric in India. It was fate. His conversion presented a certain sense of closure, of completing the circle.

His interest in Islam found secular outlets. A giant black and white poster of Malcolm X appeared on Anthrax's bedroom wall. A huge photo of Los Angeles Black Panther leader Elmer Pratt followed soon after.

The photo was captioned, 'A coward dies a million deaths, a brave man dies but one'. The last bit of wall was covered in posters of hip-hop bands from ceiling to floor. A traditional Indian sword adorned the top of one of the many bookcases. It complemented the growing collection of books on martial arts. A well-loved copy of The Art of War by Sun Tzu sat on the shelf next to Homer's Ulysses, The Lord of The Rings, The Hobbit, a few old Dungeons and Dragons books, works of mythology from India and Egypt. The shelves did not contain a single work of science fiction. Anthrax shaved his head. His mother may not have been surprised by the conversion to Islam, but the head shaving went a bit over the top.

Anthrax pursued NOI with the same vigour with which he attacked hacking. He memorised whole speeches of Farrakhan and began speaking like him, commenting casually on 'those caucasian, blue-eyed devils'.

He quoted people he had discovered through NOI. People who described the US Federal Reserve Bank as being controlled by Jews. People who spoke of those hooked-nose, bagel-eating, just-crawled-out-of-a-cave Jews. Anthrax denied the existence of the Holocaust.

'You're shaping up to be quite a little Hitler,' his father told Anthrax.

His father disliked the NOI literature showing up at the house. It seemed to frighten him. Receiving blueprints in the mail for overthowing governments didn't sit well with the neighbours in the quiet suburban street of the provincial town.

'Watch out,' he warned his son. 'Having these thing turn up in your mailbox can be dangerous. It will probably earmark you for some sort of investigation. They will follow you around.'

The traffic raced. The ethernet cables attached to System X were a regular speedway. People whizzed in and out of the mystery site like a swarm of bees. In only twelve hours, the sniffer file topped 100 k.

Many of the connections went from System X to the major telecommunications company. Anthrax headed in that direction.

He considered how to route the attack. He could go through a few diverters and other leapfrog devices to cover his trail, thus. .h.i.tting 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 pa.s.sword.

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.

He leaned away from his keyboard and stretched. Exhaustion was beginning to set in. He hadn't slept in almost 48 hours. Occasionally, he had left his computer terminal to eat, though he always brought the food back to the screen. His mother popped her head in the doorway once in a while and shook her head silently. When he noticed her there, he tried to ease her concerns. 'But I'm learning lots of things,' he pleaded. She was not convinced.

He also broke his long hacking session to pray. It was important for a devout Muslim to practice salat--to pray at least five times a day depending on the branch of Islam followed by the devotee. Islam allows followers to group some of their prayers, so Anthrax usually grouped two in the morning, prayed once at midday as normal, and grouped two more at night. An efficient way to meet religious obligations.

Sometimes the time just slipped away, hacking all night. When the first hint of dawn snuck up on him, he was invariably in the middle of some exciting journey. But duty was duty, and it had to be done. So he pressed control S to freeze his screen, unfurled the prayer mat with its built-in compa.s.s, faced Mecca, knelt down and did two sets of prayers before sunrise. Ten minutes later he rolled the prayer mat up, slid back into his chair, typed control Q to release the pause on his computer and picked up where he left off.

This company's computer system seemed to confirm what he had begun to suspect. System X was the first stage of a project, the rest of which was under development. He found a number of tables and reports in System X's files. The reports carried headers like 'Traffic a.n.a.lysis', 'calls in' and 'calls out', 'failure rate'. It all began to make sense to Anthrax.

System X called up each of the military telephone exchanges in that list. It logged in using the computer-generated name and pa.s.sword.

Once inside, a program in System X polled the exchange for important statistics, such as the number of calls coming in and out of the base.

This information was then stored on System X. Whenever someone wanted a report on something, for example, the military sites with the most incoming calls over the past 24 hours, he or she would simply ask System X to compile the information. All of this was done automatically.

Anthrax had read some email suggesting that changes to an exchange, such as adding new telephone lines on the base, had been handled manually, but this job was soon to be done automatically by System X.

It made sense. The maintenance time spent by humans would be cut dramatically.

A machine which gathers statistics and services phone exchanges remotely doesn't sound very s.e.xy on the face of it, until you begin to consider what you could do with something like that. You could sell it to a foreign power interested in the level of activity at a certain base at a particular time. And that is just the beginning.

You could tap any unencrypted line going in or out of any of the 100 or so exchanges and listen in to sensitive military discussions. Just a few commands makes you a fly on the wall of a general's conversation to the head of a base in the Philippines. Anti-government rebels in that country might pay a pretty penny for getting intelligence on the US forces.

All of those options paled next to the most striking power wielded by a hacker who had unlimited access to System X and the 100 or so telephone exchanges. He could take down that US military voice communications system almost overnight, and he could do it automatically. The potential for havoc creation was breathtaking. It would be a small matter for a skilled programmer to alter the automated program used by System X. Instead of using its dozen or more modems to dial all the exchanges overnight and poll them for statistics, System X could be instructed to call them overnight and reprogram the exchanges.

What if every time General Colin Powell picked up his phone, he was be automatically patched through to some Russian general's office? He wouldn't be able to dial any other number from his office phone. He'd pick up his phone to dial and there would be the Russian at the other end. And what if every time someone called into the general's number, they ended up talking to the stationery department? What if none of the phone numbers connected to their proper telephones? No-one would be able to reach one another. An important part of the US military machine would be in utter disarray. Now, what if all this happened in the first few days of a war? People trying to contact each other with vital information wouldn't be able to use the telephone exchanges reprogrammed by System X.
