There was something strange about the data, Force thought. It was not structured in a way which suggested the Citibank machine was merely transmitting data to another machine. It looked more like a text file which was being dumped from a computer to a line printer.

Force sat back and considered his exquisite discovery. He decided this was something he would share only with a very few close, trusted friends from The Realm. He would tell Phoenix and perhaps one other member, but no-one else.

As he looked through the data once more, Force began to feel a little anxious. Citibank was a huge financial inst.i.tution, dependent on the complete confidence of its customers. The corporation would lose a lot of face if news of Force's discovery got out. It might care enough to really come after him. Then, with the sudden clarity of the lightning strike photo which hung on his wall, a single thought filled his mind.

I am playing with fire.

'Where did you get those numbers?' Par asked Force next time they were both on Altos.

Force hedged. Par leaped forward.

'I checked those numbers for you. They're valid,' he told Force. The American was more than intrigued. He wanted that network address. It was l.u.s.t. Next stop, mystery machine. 'So, what's the address?'

That was the one question Force didn't want to hear. He and Par had a good relationship, sharing information comfortably if occasionally.

But that relationship only went so far. For all he knew, Par might have a less than desirable use for the information. Force didn't know if Par carded, but he felt sure Par had friends who might be into it.

So Force refused to tell Par where to find the mystery machine.

Par wasn't going to give up all that easily. Not that he would use the cards for free cash, but, hey, the mystery machine seemed like a very cool place to check out. There would be no peace for Force until Par got what he wanted. Nothing is so tempting to a hacker as the faintest whiff of information about a system he wants, and Par hounded Force until the Australian hacker relented just a bit.

Finally Force told Par roughly where DEFCON had been scanning for addresses when it stumbled upon the CitiSaudi machine. Force wasn't handing over the street address, just the name of the suburb. DEFCON had been accessing the Citibank network through Telenet, a large American data network using X.25 communications protocols. The sub-prefixes for the Citibank portion of the network were 223 and 224.

Par pestered Force some more for the rest of the numbers, but the Australian had dug his heels in. Force was too careful a player, too fastidious a hacker, to allow himself to get mixed up in the things Par might get up to.

OK, thought the seventeen-year-old Par, I can do this without you. Par estimated there were 20000 possible addresses on that network, any one of which might be the home of the mystery machine. But he a.s.sumed the machine would be in the low end of the network, since the lower numbers were usually used first and the higher numbers were generally saved for other, special network functions. His a.s.sumptions narrowed the likely search field to about 2000 possible addresses.

Par began hand-scanning on the Citibank Global Telecommunications Network (GTN) looking for the mystery machine. Using his knowledge of the X.25 network, he picked a number to start with. He typed 22301, 22302, 22303. On and on, heading toward 22310000. Hour after hour, slowly, laboriously, working his way through all the options, Par scanned out a piece, or a range, within the network. When he got bored with the 223 prefix, he tried out the 224 one for a bit of variety.

Bleary-eyed and exhausted after a long night at the computer, Par felt like calling it quits. The sun had splashed through the windows of his Salinas, California, apartment hours ago. His living room was a mess, with empty, upturned beer cans circling his Apple IIe. Par gave up for a while, caught some shut-eye. He had gone through the entire list of possible addresses, knocking at all the doors, and nothing had happened. But over the next few days he returned to scanning the network again. He decided to be more methodical about it and do the whole thing from scratch a second time.

He was part way through the second scan when it happened. Par's computer connected to something. He sat up and peered toward the screen. What was going on? He checked the address. He was sure he had tried this one before and nothing had answered. Things were definitely getting strange. He stared at his computer.

The screen was blank, with the cursor blinking silently at the top.

Now what? What had Force done to get the computer to sing its song?

Par tried pressing the control key and a few different letters.

Nothing. Maybe this wasn't the right address after all. He disconnected from the machine and carefully wrote down the address, determined to try it again later.

On his third attempt, he connected again but found the same irritating blank screen. This time he went through the entire alphabet with the control key.

Control L.

That was the magic keystroke. The one that made CitiSaudi give up its mysterious cache. The one that gave Par an adrenalin rush, along with thousands and thousands of cards. Instant cash, flooding his screen.

He turned on the screen capture so he could collect all the information flowing past and a.n.a.lyse it later. Par had to keep feeding his little Apple IIe more disks to store all the data coming in through his 1200 baud modem.

It was magnificent. Par savoured the moment, thinking about how much he was going to enjoy telling Force. It was going to be sweet. Hey, Aussie, you aren't the only show in town. See ya in Citibank.

An hour or so later, when the CitiSaudi data dump had finally finished, Par was stunned at what he found in his capture. These weren't just any old cards. These were debit cards, and they were held by very rich Arabs. These people just plopped a few million in a bank account and linked a small, rectangular piece of plastic to that account. Every charge came directly out of the bank balance. One guy listed in the data dump bought a $330,000 Mercedes Benz in Istanbul--on his card. Par couldn't imagine being able to throw down a bit of plastic for that. Taking that plastic out for a spin around the block would bring a whole new meaning to the expression, 'Charge it!'

When someone wins the lottery, they often feel like sharing with their friends. Which is exactly what Par did. First, he showed his room-mates. They thought it was very cool. But not nearly so cool as the half dozen hackers and phreakers who happened to be on the telephone bridge Par frequented when the master of X.25 read off a bunch of the cards.

Par was a popular guy after that day. Par was great, a sort of Robin Hood of the underground. Soon, everyone wanted to talk to him. Hackers in New York. Phreakers in Virginia. And the Secret Service in San Francisco.

Par didn't mean to fall in love with Theorem. It was an accident, and he couldn't have picked a worse girl to fall for. For starters, she lived in Switzerland. She was 23 and he was only seventeen. She also happened to be in a relationship--and that relationship was with Electron, one of the best Australian hackers of the late 1980s. But Par couldn't help himself. She was irresistible, even though he had never met her in person. Theorem was different. She was smart and funny, but refined, as a European woman can be.

They met on Altos in 1988.

Theorem didn't hack computers. She didn't need to, since she could connect to Altos through her old university computer account. She had first found Altos on 23 December 1986. She remembered the date for two reasons. First, she was amazed at the power of Altos--that she could have a live conversation on-line with a dozen people in different countries at the same time. Altos was a whole new world for her. Second, that was the day she met Electron.

Electron made Theorem laugh. His sardonic, irreverent humour hit a chord with her. Traditional Swiss society could be stifling and closed, but Electron was a breath of fresh air. Theorem was Swiss but she didn't always fit the mould. She hated skiing. She was six feet tall. She liked computers.

When they met on-line, the 21-year-old Theorem was at a crossroad in her youth. She had spent a year and a half at university studying mathematics. Unfortunately, the studies had not gone well. The truth be told, her second year of university was in fact the first year all over again. A cla.s.smate had introduced her to Altos on the university's computers. Not long after she struck up a relationship with Electron, she dropped out of uni all together and enrolled in a secretarial course. After that, she found a secretarial job at a financial inst.i.tution.

Theorem and Electron talked on Altos for hours at a time. They talked about everything--life, family, movies, parties--but not much about what most people on Altos talked about--hacking. Eventually, Electron gathered up the courage to ask Theorem for her voice telephone number.

She gave it to him happily and Electron called her at home in Lausanne. They talked. And talked. And talked. Soon they were on the telephone all the time.

Seventeen-year-old Electron had never had a girlfriend. None of the girls in his middle-cla.s.s high school would give him the time of day when it came to romance. Yet here was this bright, vibrant girl--a girl who studied maths--speaking to him intimately in a melting French accent. Best of all, she genuinely liked him. A few words from his lips could send her into silvery peals of laughter.

When the phone bill arrived, it was $1000. Electron surrept.i.tiously collected it and buried it at the bottom of a drawer in his bedroom.

When he told Theorem, she offered to help pay for it. A cheque for $700 showed up not long after. It made the task of explaining Telecom's reminder notice to his father much easier.

The romantic relationship progressed throughout 1987 and the first half of 1988. Electron and Theorem exchanged love letters and tender intimacies over 16000 kilometres of computer networks, but the long-distance relationship had some b.u.mpy periods. Like when she had an affair over several months with Pengo. A well-known German hacker with links to the German hacking group called the Chaos Computer Club, Pengo was also a friend and mentor to Electron. Pengo was, however, only a short train ride away from Theorem. She became friends with Pengo on Altos and eventually visited him. Things progressed from there.

Theorem was honest with Electron about the affair, but there was something unspoken, something below the surface. Even after the affair ended, Theorem was sweet on Pengo the way a girl remains fond of her first love regardless of how many other men she has slept with since then.

Electron felt hurt and angry, but he swallowed his pride and forgave Theorem her dalliance. Eventually, Pengo disappeared from the scene.

Pengo had been involved with people who sold US military secrets--taken from computers--to the KGB. Although his direct involvement in the ongoing international computer espionage had been limited, he began to worry about the risks. His real interest was in hacking, not spying. The Russian connection simply enabled him to get access to bigger and better computers. Beyond that, he felt no loyalty to the Russians.

In the first half of 1988, he handed himself in to the German authorities. Under West German law at the time, a citizen-spy who surrendered himself before the state discovered the crime, and thus averted more damage to the state, acquired immunity from prosecution.

Having already been busted in December 1986 for using a stolen NUI, Pengo decided that turning himself in would be his best hope of taking advantage of this legal largesse.

By the end of the year, things had become somewhat hairy for Pengo and in March 1989 the twenty-year-old from Berlin was raided again, this time with the four others involved in the spy ring. The story broke and the media exposed Pengo's real name. He didn't know if he would eventually be tried and convicted of something related to the incident. Pengo had a few things on his mind other than the six-foot Swiss girl.

With Pengo out of the way, the situation between Theorem and the Australian hacker improved. Until Par came along.

Theorem and Par began innocently enough. Being one of only a few girls in the international hacking and phreaking scene and, more particularly, on Altos, she was treated differently. She had lots of male friends on the German chat system, and the boys told her things in confidence they would never tell each other. They sought out her advice. She often felt like she wore many hats--mother, girlfriend, psychiatrist--when she spoke with the boys on Altos.

Par had been having trouble with his on-line girlfriend, Nora, and when he met Theorem he turned to her for a bit of support. He had travelled from California to meet Nora in person in New York. But when he arrived in the sweltering heat of a New York summer, without warning, her conservative Chinese parents didn't take kindly to his unannounced appearance. There were other frictions between Nora and Par. The relationship had been fine on Altos and on the phone, but things were just not clicking in person.

He already knew that virtual relationships, forged over an electronic medium which denied the importance of physical chemistry, could sometimes be disappointing.

Par used to hang out on a phone bridge with another Australian member of The Realm, named Phoenix, and with a fun girl from southern California. Tammi, a casual phreaker, had a great personality and a hilarious sense of humour. During those endless hours chatting, she and Phoenix seemed to be in the throes of a mutual crush. In the phreaking underground, they were known as a bit of a virtual item. She had even invited Phoenix to come visit her sometime. Then, one day, for the fun of it, Tammi decided to visit Par in Monterey. Her appearance was a shock.

Tammi had described herself to Phoenix as being a blue-eyed, blonde California girl. Par knew that Phoenix visualised her as a stereotypical bikini-clad, beach bunny from LA. His perception rested on a foreigner's view of the southern California culture. The land of milk and honey. The home of the Beach Boys and TV series like 'Charlie's Angels'.
