The intruder rapidly passed through the file indices of Chrysler’s engineering mainframe. A moment later, a message from Carl appeared across the bottom of the screen, warning of an imminent network shutdown.
‘Message received, Carl,’ Kilkenny said. ‘Our hacker is shutting down.’
The Chrysler screen vanished after the intruder logged off. A few more quick keystrokes and he was out of the Warlock server. Grin’s jaw dropped when the screen filled with the live image of Moynes’s system- administration screen.
‘Our unwelcome friend is in your sys-ad program. It looks like he’s playing around with the logs.’
They could hear Moynes punching keys to bring up the information on his computer. ‘I don’t see a thing from my side. You sure?’
‘It’s right here in front of me,’ Grin assured his colleague. ‘He’s going after the network accounting logs.’
‘Shit! What the hell is he doing in my computer?’ Moynes was furious as he scrambled through his network files looking for the hacker. ‘He’s locked me out of the logs. I am not a happy camper!’
The laptop screen went blank and Grin slumped back in his chair, disappointed. ‘He’s off the network.’
‘I don’t know about you guys, but I’m pissed! In five seconds, I’m going to have an office full of angry users, topped off by a short-fused boss who’s going to wonder why I brought the whole network down.’
Grin understood his friend’s anger-the situation was a lot like finding a burglar in one’s home. ‘Carl, it had to be done. We’ve got a dangerous player out there who’s running fast and loose through our network. That’s bad business for all of us, and I’m sure your boss will understand. We’ll back you up all the way.’
‘I’d hope so, since I have no proof that any of this happened.’ Moynes sounded a little calmer, but not much.
‘Actually, you do have proof. The laptop we’re using recorded most of this hack, including your heroic system shutdown.’
‘Grin, I feel like I just threw myself on a grenade.’ Moynes’s anger seemed to be dissipating, but his mood was still foul. ‘Speaking of grenades, my boss is coming down the corridor, and she doesn’t look happy. Gotta go, guys.’
‘Call if you need us, Carl.’
‘Thanks, Grin.’
Moynes’s line went dead and Grin switched the humming speaker off. ‘Well, that was fun. What do we do for an encore?’
Kilkenny pulled the optical-disk cartridge from the laptop’s external drive. ‘I think it’s time we reported this incident. It may not seem like much, but we’ve just witnessed a crime.’
Later that afternoon, Nolan and Grin sat in Sean Kilkenny’s office with two agents from the FBI’s Detroit office. The agents took their statements and toured the computer lab. Despite the fact that computer crime was a serious offense, it didn’t always get the same treatment from the law-enforcement community as bank robbery and drug trafficking. The FBI agents were polite but non-committal until Nolan replayed the intruder’s penetration of Chrysler’s computer network.
‘Do you have any questions?’ Nolan asked as the computer screen went blank.
‘Can we have a copy of that disk?’ Special Agent Ullrich replied. ‘I’m sure our computer lab techs would love to watch this guy in action.’
‘Already done, Agent Ullrich,’ Grin said as he handed over a duplicate diskette.
Ullrich slipped the diskette into her briefcase with her notes. ‘Thank you.’
‘I appreciate your coming out here,’ Sean told the agents, ‘but what should we do about this situation?’
‘There’s not much that can be done, sir,’ Ullrich replied. Her answer wasn’t a dismissal of their complaint, simply a matter of fact. ‘Our only hope is to catch this individual in the act. Special Agent Harbke and I are experienced in dealing with these types of criminals, and, believe me, it takes time to build a case against them.’
‘Most of our successful prosecutions are the result of turning a hacker against his own ring,’ added Harbke. ‘Unless there is some physical evidence of the crime, we’re stuck. Your disk is a start, but it doesn’t mean a thing until we can tie it to somebody. I think you handled this situation correctly. This hacker is using the university’s network to cover his tracks. Since he doesn’t know you spotted him, odds are he’ll be back. What I’m going to suggest to my superiors is that we obtain the necessary warrants to trace your network lines during one of these intrusions.’
‘I don’t think that you’ll have any problem with MARC or the university with regard to the line taps, Agent Harbke,’ Sean assured her.
‘We usually don’t in situations like this.’ Harbke smiled. She knew from experience that high-profile victims of this type of crime were normally very helpful. ‘In the meantime, please keep monitoring the network for any further intrusions. The more information we have about this hacker’s methods, the better chance we have of catching him. Thank you for your time today, gentlemen. I’ll contact you as soon as we get the warrants.’
After escorting the FBI agents out, Sean Kilkenny returned to the lab with Grin and his son. ‘When I got up this morning, I had no idea that I would spend the better part of my afternoon with the FBI. I still can’t believe that somebody just waltzed through our network so easily. If this hacker is behind the anomalous signal you’ve been chasing for the past month, I don’t even want to think about what he’s gotten away with already.’
‘At least we’re onto him, Dad.’
‘Actually, we’d still be in the dark if you and Kelsey weren’t studying every little burp that processor of hers makes,’ Grin admitted frankly. ‘If it was just little old me in here, I very much doubt I would have spotted this guy. Our hacker’s got a real nice touch.’
‘Grin’s right-we were lucky to have discovered this guy at all. Whoever it is doesn’t know that we’re onto him yet, and that’s the only advantage we have right now.’
Sean moved to the next item on his mental list of concerns. ‘Is Kelsey’s processor secure from tampering by this hacker?’
Nolan thought about his father’s question for a minute, going over in his head the optical processor’s linkages to the MARC network. ‘The processor itself is well insulated from the network, so this guy can’t get a direct feed into it, but all of our project data is stored on the mainframe. Good thing Grin is religious about backing up the system. I don’t know what I fear more, though-having this guy steal our work or vandalizing it.’
‘So much for a victimless crime.’ Sean sighed. ‘Boys, I want you to cooperate with the FBI fully on this matter. Stopping this hacker is now your number-one priority. We are an information-based concern, so we can’t afford to have some criminal punching holes in our security. Do what it takes to nail this person.’

April 15
Traffic was never clear and easy in downtown Chicago, but Moy drove as quickly as Lake Shore Drive allowed and pulled into the parking garage beneath the twin black towers overlooking Lake Michigan.
Following a disturbing call from his wife, Phillip Moy had canceled the rest of his afternoon appointments and left for the day. Cynthia Moy had sounded frantic over the phone, pleading with him to come home immediately. Although she couldn’t explain what had happened, Moy knew his wife wasn’t one to raise an alarm unnecessarily.
As he entered his condominium, Moy was met by his wife, who wore an expression of deep concern. She was normally a pleasant, happy soul possessed of great inner strength. When she looked this way, he knew to expect bad news. Moy embraced his wife, sensing her concern. ‘Cynthia, what’s wrong?’
Her voice was a quiet, dull whisper. ‘Your father has come to visit, and he has brought a guest.’
Moy’s wife had always gotten along well with her father-in-law. The aging physicist often joked that if they ever divorced, he would keep Cynthia. Inside the living room, which faced Lake Michigan, was Moy’s father and a man he didn’t recognize. The elder Moy sat on the couch, deep in thought, as the visitor turned from the window to face him.
