KEY WEST, FL. – Yvonne poured through the maliciously functioning server while

Colin slept the night?s activities off. It was tough working with a

hangover, but nothing she hadn?t done before?just a little harder to

focus was all. The pounding, claustrophobic sensation left over by

her partying made her imagine the server as a cave, with its dark

secrets hidden at the bottom of some impossibly obscure passage.

Cyber spelunker, she thought, and started to laugh, but laughter was

painful this early. A Bloody Mary might not solve the computer

mystery, but it would take the edge off her discomfort.

Colin, still naked, met her at the bar. He grabbed her wrist and

pulled her towards him, and tried to slip his other hand under her tshirt,

but an elbow to his Adam?s apple put a stop to that.

?Hey, honey, what?s the matter??

?Sorry, Col. But duty calls. I?ve got a renegade chip in that server

and Stokes is waiting for an answer.?

?You sure?? He turned towards her and flexed his pecs. That

wasn?t where she was looking, however. ?You know you want to,? he

said.

Yes, she did. But the last thing she needed was another suitor,

another hanger-on, calling her when she was working, interrupting

when she relaxed with someone else. Her life alone was as good as it

could be?apart from her responsibilities to CyberCom she made

the decisions about where she went and with whom. She made the

kind of money most people could only dream of, had the kind of

talent and respect others could never even imagine. She wasn?t going

to let that be tied down in a relationship, no matter how good looking

or important the man was. She wouldn?t do it for Colin, and she

certainly wouldn?t do it for Stokes. If only he were here so she could

throw an elbow his way.

?Get dressed, Colin. Bring me a Bloody Mary and then you can

make us some breakfast. There?s eggs and bacon in the fridge. And

don?t forget the Tabasco.?

He did as he was told. At least dating younger men meant they

listened occasionally. But that only reminded her of her age. She

didn?t want to be anyone?s mommy, either. Maybe that?s why she?d let

Lillian go off to live with her family all those years ago?considering

how she?d been treated by the relatives as a child it might not have

been the best decision, but then a life spent ignored while mommy

glued her gaze to a monitor wouldn?t have been good for Lillian

either. Yvonne had sent enough money back to Moscow to make sure

Lillian received the best education and never wanted for material

needs, but she wondered often about her daughter?s emotional state.

The letters between them were rare, now that Lillian was almost

eighteen. God, she was old enough now to date Colin too.

While he rummaged for pans and plates she turned her attention

back to the server. How engrossing, this work. In a sense it was

liberating too, because it demanded a level of concentration that

made life?s problems recede into the subconscious. Never mind the

dysfunction of her relatives. Never mind the boys and their neverending

games to impress her. This was the chess match. Someone

had placed this chip on the motherboard, right under the noses of the

Network Systems techs, and hid it and its functions well enough that

they never suspected until it turned on and ceded control to a remote

commander. And the programming! She hooked the board to her

system to read the code embedded within. Layers and layers of

commands and parameters, perfectly designed to isolate sub stations

and controllers, and avoid detection by feeding dummy readings to

the CalTrans sensors. Whoever designed this had to know not only

the workings of the server, but those of the entire traffic grid and its

stations, in order to know how to shut them down. And the chip made

it all easy. It acted as a back door through which the attackers could

access at any time, as though they had made a skeleton key that

unlocked the traffic control program.

Exquisite.

And as she scanned through thousands of lines of code written

in redundant languages?even C and C++?and saw the

programmable logic controller rootkit, she knew this was an offspring

of Stuxnet, not nearly as involved, but still capable of incredible

damage. There was root kit, there the replacement DLLs for the

network interfaces. There was the privilege escalation that made it

possible to override any attempt by the authorized user to wrest

control by changing the root passwords. Since changing the default

passwords would disable the server software completely, Network

Systems protocols dictated they remain unchanged, giving the worm

the opportunity to proliferate exponentially, throughout the system,

into any connected device. A single rogue chip might produce access

to dozens of critical functions. In any server that had been

compromised, infiltration was made ridiculously easy, and could clear

the way for additional breeches and takeovers, like falling

dominoes?perhaps even some that the chip?s designers hadn?t even

imagined. Who knew what other control systems might be on the

verge of failure?

Stuxnet had needed a team of the best engineers to program it?

a team at a government level?and not just any government. Even

this new variant required a level of understanding and capability at

the top of the programming food chain. Could another country be

backing this effort to infiltrate critical systems? Stuxnet had helped

delay Iran?s effort to achieve nuclear power and weapons. Now

maybe someone was trying to turn the tables and damage America?s

infrastructure, and as she and hundreds of experts knew, many of

the country?s various infrastructure components were already in

danger of failing even without the push from Stuxnet. This kind of

worm, with some additional engineering, could potentially give

control of vital systems to a hostile force. Instead of mere failure,

these systems could be made to cause damage?both physical and

economic.With crucial systems in someone else?s control, the nation

could be essentially powerless to protect itself.

She texted Stokes and told him she needed to speak with Rita

Sanchez and whoever headed logistics at Network Systems. A few

seconds later, he was signaling on the Scan-U, and his 3-D image

appeared in front of the monitor.

?You?re up early, Rohan.?

?Frankly, I?ve been up for hours waiting for you to tell me

something that I can relay to theWhite House.What have you got??

?This.? She held up the evil chip. ?Somebody got a little crazy

with the soldering gun.?

His electronic head turned to look at it. ?Yvonne, did I ever

mention you have a gift for understatement??

?Whoever?s behind this plopped this chip right into the middle of

the motherboard. And it?s so small and so well programmed even I

might not have noticed its presence. So of course it had no trouble

getting past the Network Systems team.?

?I?d better get Rita on the line with us.?

?Hmmm,? Yvonne said. ?Already on a first-name basis?

Something going on there??

?Don?t make jokes. You know I don?t go for the super bitch type.

I like a woman who likes to have fun. Someone with a sense of

adventure.?

?Too bad you?re not very adventurous yourself.?

?What? What do you mean??

It was just a line, but she had touched a nerve.

?Oh come on, Rohan. You sit at a desk all day and push paper

and buttons. Once in a while you run off to a meeting. That?s not

exactly my idea of adventurous.?

?Is that why you broke it off with me??

?Sure, sure, darling. The last time you did field work was when

you were with the CIA and arrested me.?

?That was a pretty exciting time.?

?And I was impressed. I?d been able to keep my activities a secret

from the government and the mob. You were the only one who

figured me out.?

?Yvonne, I?m still trying to figure you out.? Stokes paused, then

added, ?You know, I could get back out there anytime I want.?

?Oh yes, Rohan. You just tell the Assistant for Homeland Security

and Counterterrorism his top man is taking some time off to chase

the bad guys. I?m sure he?ll understand.?

Colin called to her as he brought two steaming plates from the

kitchen. ?I have your order, madame. Would you care for another

Bloody Mary??

Stokes?s holograph pivoted left, as though by doing so it could see

into the kitchen. ?Who is that??

?Oh, just a house guest.?

?But he?s not wearing a shirt.?

Yvonne laughed. ?You?re lucky he?s wearing pants. Colin, say

hello to the nice man.?

Colin stopped and smiled. ?Hello, Rohan.? He waved into the

screen, and then went back to the bar. She imagined Colin?s

projection appearing in Stokes?s office, shaking a slightly transparent

hand in his face.

?He doesn?t get to call me Rohan,? Stokes said.

?I?ll remind him next time he?s here.?

Stokes puffed his cheeks as though he?d conceded this round of

banter. ?All right, Ms. Tran, what else can you tell me about this

chip??

?Not much yet. That?s why I need the Network Systems people.

They may be able to help at last.?

?Did you ping the chip?s C and C yet??

?I?ll do that while you?re getting Ms. Sanchez out of bed?oops!

I mean, while you?re getting her on the Scan-U.?

?Goodbye, Yvonne. I?ll signal you in a few minutes.?

She put the Scan-U to sleep and brought her breakfast back into

the kitchen to join Colin. She found him instead in the living room,

hooked up to the huge flat screen Stokes had sent her when they were

having their affair. He?d accessed an online community of

Armageddon Squadron.

?I?m kicking some serious butt,? he said. ?Commando style.?

?Didn?t you get enough of that when you flew drones??

?There?s never enough when you can smell the kill.?

If the search for the origin of the chip meant physically tracking

down the source, his flying skills, both real and virtual, might be an

asset. But he was so young; in many ways still a boy.Maybe she would

boot him back to the northern Keys instead.

Yvonne watched as he manipulated a computer generated

aircraft while shoveling his scrambled eggs. He had the coordination

of an athlete, able to accomplish difficult maneuvers without

conscious thought, and she could see how he?d been able to fly the Air

Force?s drones past enemy defenses and over moon-like terrain to

drop ordnance on suspected terrorists. He loved it, practically

breathed it. But like her, he found out quickly he could make more

money in the private sector. His game really was a game?online

flight simulator tournaments, which had made him financially

independent. She wasn?t unhappy working for the government?and

there was even some time to pick up occasional work from cash-rich

corporate clients, not to mention the odd gig siphoning tens of

thousands from illegal offshore casinos or other scam artists who

managed to stay out of the authorities? reach (and at which Stokes

looked the other way). It made a nice balance, even if it wasn?t as

lucrative as a pure black hat existence. At times it made her feel

patriotic, that she was returning the favor America had given her by

letting her stay and go to MIT. Maybe he would someday see it the

same way, too.

She set to tracing the IP address the chip was programmed to

send to. But as expected the trail ran cold short of the final

destination. She was able to reach back to Hong Kong, but no further.

It reached the headquarters of Cathay Computer Works, but from

there she could not trace route past the firewall doing the network

address translation for their private network.

A half hour later Stokes signaled that he had the NetSys

executives on the Scan-U. Yvonne logged in to see his image scanning

her bungalow, as if looking for Colin again. Two more holographs

began to resolve, and Yvonne called up her Cyber Styletto image.

Rita Sanchez and another man appeared.

?Ms. Sanchez. Good to see you again.?

?Good to not see you again,? Sanchez said.

?Ah, yes. Sorry about that. But you know the regulations

regarding my identity.? She studied the face of the man who

materialized along with Sanchez. ?And Liang Runnan,? Yvonne said.

?Who is that? How do you know me?? he said.

?I know of you. CEO at Pebble Computer in Beijing. Put the

company on the map. Then you disappeared in 1997. Rumor has it

certain Chinese government officials wanted kickbacks for

introductions to foreign investors and you couldn?t pay.?

?I assure you my departure from that company was a personal

decision. I only wished to spend more time with my family.?

?It didn?t make sense, considering the system of extortion over

there. Everybody knows to put something away for when the

government comes calling. Unless it?s already been extorted, so to

speak.?

?What are you insinuating?? Liang asked. ?Who is this, please??

Stokes cut in. ?Our agent knows better than to spread unfounded

gossip, doesn?t she??

?So, now you?re working for Network Systems.? Yvonne

continued as if Stokes hadn?t said a word.

?I am Senior Vice President and Director of Logistics and

Manufacturing for the Pacific Rim Region,? Liang said.

?Wow,? Yvonne said. ?That must be a big business card.?

?What can we do for you, Miss??? Liang said.

?Actually, it?s what I can do for you. The source of your

infiltration was a microchip, planted on the motherboard of your

compromised server. The chip is controlled by an entity somewhere

in China, but I haven?t been able to pinpoint it yet. The signal stops

in Hong Kong, just a stone?s throw from Guangzhou.?

?That is where the server is manufactured,? Liang said. ?A

microchip? Are you sure??

?All I have is the serial number. Can you tell me who made it??

She read the number to him, and Liang searched his database,

but he reported no returns. ?I will launch a full investigation,? he

said.

?There isn?t time for that,? Yvonne said. ?Stokes, I?m going to

have to track this down the old fashioned way. I?m going to put

together a team and go to Hong Kong. The only way we can take it

further is to go to the data center at Cathay.? She smiled over the

possibility of doing the field work herself, getting out of the dark

computer labs she haunted and out of reach of Stokes and the other

government stiffs who?d cramped her style since the arrest and

subsequent arrangement.

?Finally,? Sanchez said. ?Some progress.?

?Of course there will be a few expenses not covered in the

original agreement,? Yvonne said.

?Expenses? With what we?re paying you? Out of the question.?

?Nothing major,? Yvonne went on. ?First-class airfare, luxury

hotel accommodations, expense account??

?She?s only kidding,? Stokes said. ?And if there are any extra

costs, the government will cover them.?

?Oh, Rohan. Shame on you,? Yvonne said. ?Adding to the

national debt. What would the president say??

?Just keep the expenses to a minimum,? he said.

When Sanchez and Runnan signed off, Yvonne shed her avatar

to finish up with Stokes. ?I will need a team, Rohan. You know I?m

still a suspect for hacking the W88 caper in China, so I need some

people I trust to help me. It?ll be easier to remain undercover if I

have the right people to work with.?

?You?re really willing to go back there, Yvonne? If they catch you

they might put you on trial anyway, with or without proof.?

?Well, you can?t blame them. If I hadn?t caught them with their

pants down over those nuclear warhead designs, they might have

invaded Taiwan. I can see why they?d be a little upset.?

?Speaking of having someone?s pants down, is that person I saw

at your place earlier still hanging around??

?You mean Colin? I?ll be bringing him along, if that?s what you

want to know.?

Colin called from the living room, ?Road trip!?

Yes, he was a boy at heart. ?Separate bedrooms, I promise,? she

said.

?Bring me the receipts or I won?t cover the hotel.?

?Rohan, darling. Jealous to the end. Listen, I?m going to call an

old friend, Buck Ryan. I want him and his crew in on this.?

?Ryan Repo? If he?s still kicking I think it?s a good idea. Get some

experience involved.?

?Still kicking? Buck will never retire,? she said. ?He has too much

fun screwing with deadbeats. You ever the see the face of a corporate

exec when his airplane is repossessed??

?Can?t say that I have. Buck still headquartered in San

Francisco??

?As soon as I confirm with him I?ll fly there to plan how we?re

going to proceed. I?ll call you as soon as we have it together.?

Yvonne?s next call was to Ryan?s cell.

?Perfect timing,? Buck said. ?I?ve got a triple seven in Shenzhen

that I?m snatching on the twenty-fifth. Provincial official got over his

head with an Aussie bank, and we?re going to give him a reverse

Christmas present.?

?Don?t forget to leave a lump of coal in his stocking,? Yvonne

said.

?Ha! You know I?ve missed that sense of humor of yours. It?ll be

great to work with you again. What have you got cooking this time??

?Buck, you?re going to need to call in your muscle for this job,?

she said. ?We?re talking cyber war.?
