"TREAT YOUR FONCARD AS YOU WOULD ANY CREDIT CARD. TO SECURE AGAINST FRAUD, NEVER GIVE YOUR FONCARD NUMBER OVER THE PHONE UNLESS YOU INITIATED THE CALL. IF YOU RECEIVE SUSPICIOUS CALLS PLEASE NOTIFY CUSTOMER SERVICE IMMEDIATELY!"
I examined my watch. Still plenty of time left for the FCIC to carry on. I sorted out the scraps of Evelyn's SPRINT bill and re-assembled them with fresh Scotch tape. Here was her ten-digit FONCARD number. Didn't seem to have the ID number necessary to cause real fraud trouble.
I did, however, have Evelyn's home phone number. And the phone numbers for a whole crowd of Evelyn's long-distance friends and acquaintances. In San Diego, Folsom, Redondo, Las Vegas, La Jolla, Topeka, and Northampton Massachusetts. Even somebody in Australia!
I examined other documents. Here was a bank statement. It was Evelyn's IRA account down at a bank in San Mateo California (total balance $1877.20). Here was a charge-card bill for $382.64. She was paying it off bit by bit.
Driven by motives that were completely unethical and prurient, I now examined the handwritten notes. They had been torn fairly thoroughly, so much so that it took me almost an entire five minutes to reassemble them.
They were drafts of a love letter. They had been written on the lined stationery of Evelyn's employer, a biomedical company. Probably written at work when she should have been doing something else.
"Dear Bob," (not his real name) "I guess in everyone's life there comes a time when hard decisions have to be made, and this is a difficult one for me—very upsetting. Since you haven't called me, and I don't understand why, I can only surmise it's because you don't want to. I thought I would have heard from you Friday. I did have a few unusual problems with my phone and possibly you tried, I hope so.
"Robert, you asked me to 'let go'...."
The first note ended. UNUSUAL PROBLEMS WITH HER PHONE? I looked swiftly at the next note.
"Bob, not hearing from you for the whole weekend has left me very perplexed...."
Next draft.
"Dear Bob, there is so much I don't understand right now, and I wish I did. I wish I could talk to you, but for some unknown reason you have elected not to call—this is so difficult for me to understand...."
She tried again.
"Bob, Since I have always held you in such high esteem, I had every hope that we could remain good friends, but now one essential ingredient is missing—respect. Your ability to discard people when their purpose is served is appalling to me. The kindest thing you could do for me now is to leave me alone. You are no longer welcome in my heart or home...."
Try again.
"Bob, I wrote a very factual note to you to say how much respect I had lost for you, by the way you treat people, me in particular, so uncaring and cold. The kindest thing you can do for me is to leave me alone entirely, as you are no longer welcome in my heart or home. I would appreciate it if you could retire your debt to me as soon as possible—I wish no link to you in any way. Sincerely, Evelyn."
Good heavens, I thought, the bastard actually owes her money! I turned to the next page.
"Bob: very simple. GOODBYE! No more mind games—no more fascination—no more coldness—no more respect for you! It's over—Finis. Evie"
There were two versions of the final brushoff letter, but they read about the same. Maybe she hadn't sent it. The final item in my illicit and shameful booty was an envelope addressed to "Bob" at his home address, but it had no stamp on it and it hadn't been mailed.
Maybe she'd just been blowing off steam because her rascal boyfriend had neglected to call her one weekend. Big deal. Maybe they'd kissed and made up, maybe she and Bob were down at Pop's Chocolate Shop now, sharing a malted. Sure.
Easy to find out. All I had to do was call Evelyn up. With a half-clever story and enough brass-plated gall I could probably trick the truth out of her. Phone-phreaks and hackers deceive people over the phone all the time. It's called "social engineering." Social engineering is a very common practice in the underground, and almost magically effective. Human beings are almost always the weakest link in computer security. The simplest way to learn Things You Are Not Meant To Know is simply to call up and exploit the knowledgeable people. With social engineering, you use the bits of specialized knowledge you already have as a key, to manipulate people into believing that you are legitimate. You can then coax, flatter, or frighten them into revealing almost anything you want to know. Deceiving people (especially over the phone) is easy and fun. Exploiting their gullibility is very gratifying; it makes you feel very superior to them.
If I'd been a malicious hacker on a trashing raid, I would now have Evelyn very much in my power. Given all this inside data, it wouldn't take much effort at all to invent a convincing lie. If I were ruthless enough, and jaded enough, and clever enough, this momentary indiscretion of hers—maybe committed in tears, who knows—could cause her a whole world of confusion and grief.
I didn't even have to have a MALICIOUS motive. Maybe I'd be "on her side," and call up Bob instead, and anonymously threaten to break both his kneecaps if he didn't take Evelyn out for a steak dinner pronto. It was still profoundly NONE OF MY BUSINESS. To have gotten this knowledge at all was a sordid act and to use it would be to inflict a sordid injury.
To do all these awful things would require exactly zero high-tech expertise. All it would take was the willingness to do it and a certain amount of bent imagination.
I went back downstairs. The hard-working FCIC, who had labored forty-five minutes over their schedule, were through for the day, and adjourned to the hotel bar. We all had a beer.
I had a chat with a guy about "Isis," or rather IACIS, the International Association of Computer Investigation Specialists. They're into "computer forensics," the techniques of picking computer-systems apart without destroying vital evidence. IACIS, currently run out of Oregon, is comprised of investigators in the U.S., Canada, Taiwan and Ireland. "Taiwan and Ireland?" I said. Are TAIWAN and IRELAND really in the forefront of this stuff? Well not exactly, my informant admitted. They just happen to have been the first ones to have caught on by word of mouth. Still, the international angle counts, because this is obviously an international problem. Phone-lines go everywhere.
There was a Mountie here from the Royal Canadian Mounted Police. He seemed to be having quite a good time. Nobody had flung this Canadian out because he might pose a foreign security risk. These are cyberspace cops. They still worry a lot about "jurisdictions," but mere geography is the least of their troubles.
NASA had failed to show. NASA suffers a lot from computer intrusions, in particular from Australian raiders and a well-trumpeted Chaos Computer Club case, and in 1990 there was a brief press flurry when it was revealed that one of NASA's Houston branch-exchanges had been systematically ripped off by a gang of phone-phreaks. But the NASA guys had had their funding cut. They were stripping everything.
Air Force OSI, its Office of Special Investigations, is the ONLY federal entity dedicated full-time to computer security. They'd been expected to show up in force, but some of them had cancelled—a Pentagon budget pinch.
As the empties piled up, the guys began joshing around and telling war-stories. "These are cops," Thackeray said tolerantly. "If they're not talking shop they talk about women and beer."
I heard the story about the guy who, asked for "a copy" of a computer disk, PHOTOCOPIED THE LABEL ON IT. He put the floppy disk onto the glass plate of a photocopier. The blast of static when the copier worked completely erased all the real information on the disk.
Some other poor souls threw a whole bag of confiscated diskettes into the squad-car trunk next to the police radio. The powerful radio signal blasted them, too.
We heard a bit about Dave Geneson, the first computer prosecutor, a mainframe-runner in Dade County, turned lawyer. Dave Geneson was one guy who had hit the ground running, a signal virtue in making the transition to computer-crime. It was generally agreed that it was easier to learn the world of computers first, then police or prosecutorial work. You could take certain computer people and train 'em to successful police work—but of course they had to have the COP MENTALITY. They had to have street smarts. Patience. Persistence. And discretion. You've got to make sure they're not hot-shots, show-offs, "cowboys."
Most of the folks in the bar had backgrounds in military intelligence, or drugs, or homicide. It was rudely opined that "military intelligence" was a contradiction in terms, while even the grisly world of homicide was considered cleaner than drug enforcement. One guy had been 'way undercover doing dope-work in Europe for four years straight. "I'm almost recovered now," he said deadpan, with the acid black humor that is pure cop. "Hey, now I can say FUCKER without putting MOTHER in front of it."
"In the cop world," another guy said earnestly, "everything is good and bad, black and white. In the computer world everything is gray."
One guy—a founder of the FCIC, who'd been with the group since it was just the Colluquy—described his own introduction to the field. He'd been a Washington DC homicide guy called in on a "hacker" case. From the word "hacker," he naturally assumed he was on the trail of a knife-wielding marauder, and went to the computer center expecting blood and a body. When he finally figured out what was happening there (after loudly demanding, in vain, that the programmers "speak English"), he called headquarters and told them he was clueless about computers. They told him nobody else knew diddly either, and to get the hell back to work.
So, he said, he had proceeded by comparisons. By analogy. By metaphor. "Somebody broke in to your computer, huh?" Breaking and entering; I can understand that. How'd he get in? "Over the phone-lines." Harassing phone-calls, I can understand that! What we need here is a tap and a trace!
It worked. It was better than nothing. And it worked a lot faster when he got hold of another cop who'd done something similar. And then the two of them got another, and another, and pretty soon the Colluquy was a happening thing. It helped a lot that everybody seemed to know Carlton Fitzpatrick, the data-processing trainer in Glynco.
The ice broke big-time in Memphis in '86. The Colluquy had attracted a bunch of new guys—Secret Service, FBI, military, other feds, heavy guys. Nobody wanted to tell anybody anything. They suspected that if word got back to the home office they'd all be fired. They passed an uncomfortably guarded afternoon.
The formalities got them nowhere. But after the formal session was over, the organizers brought in a case of beer. As soon as the participants knocked it off with the bureaucratic ranks and turf-fighting, everything changed. "I bared my soul," one veteran reminisced proudly. By nightfall they were building pyramids of empty beer-cans and doing everything but composing a team fight song.
FCIC were not the only computer-crime people around. There was DATTA (District Attorneys' Technology Theft Association), though they mostly specialized in chip theft, intellectual property, and black-market cases. There was HTCIA (High Tech Computer Investigators Association), also out in Silicon Valley, a year older than FCIC and featuring brilliant people like Donald Ingraham. There was LEETAC (Law Enforcement Electronic Technology Assistance Committee) in Florida, and computer-crime units in Illinois and Maryland and Texas and Ohio and Colorado and Pennsylvania. But these were local groups. FCIC were the first to really network nationally and on a federal level.
FCIC people live on the phone lines. Not on bulletin board systems—they know very well what boards are, and they know that boards aren't secure. Everyone in the FCIC has a voice-phone bill like you wouldn't believe. FCIC people have been tight with the telco people for a long time. Telephone cyberspace is their native habitat.
FCIC has three basic sub-tribes: the trainers, the security people, and the investigators. That's why it's called an "Investigations Committee" with no mention of the term "computer-crime"—the dreaded "C-word." FCIC, officially, is "an association of agencies rather than individuals;" unofficially, this field is small enough that the influence of individuals and individual expertise is paramount. Attendance is by invitation only, and most everyone in FCIC considers himself a prophet without honor in his own house.
Again and again I heard this, with different terms but identical sentiments. "I'd been sitting in the wilderness talking to myself." "I was totally isolated." "I was desperate." "FCIC is the best thing there is about computer crime in America." "FCIC is what really works." "This is where you hear real people telling you what's really happening out there, not just lawyers picking nits." "We taught each other everything we knew."
The sincerity of these statements convinces me that this is true. FCIC is the real thing and it is invaluable. It's also very sharply at odds with the rest of the traditions and power structure in American law enforcement. There probably hasn't been anything around as loose and go-getting as the FCIC since the start of the U.S. Secret Service in the 1860s. FCIC people are living like twenty-first-century people in a twentieth-century environment, and while there's a great deal to be said for that, there's also a great deal to be said against it, and those against it happen to control the budgets.
I listened to two FCIC guys from Jersey compare life histories. One of them had been a biker in a fairly heavy-duty gang in the 1960s. "Oh, did you know so-and-so?" said the other guy from Jersey. "Big guy, heavyset?"
"Yeah, I knew him."
"Yeah, he was one of ours. He was our plant in the gang."
"Really? Wow! Yeah, I knew him. Helluva guy."
Thackeray reminisced at length about being tear-gassed blind in the November 1969 antiwar protests in Washington Circle, covering them for her college paper. "Oh yeah, I was there," said another cop. "Glad to hear that tear gas hit somethin'. Haw haw haw." He'd been so blind himself, he confessed, that later that day he'd arrested a small tree.
FCIC are an odd group, sifted out by coincidence and necessity, and turned into a new kind of cop. There are a lot of specialized cops in the world—your bunco guys, your drug guys, your tax guys, but the only group that matches FCIC for sheer isolation are probably the child-pornography people. Because they both deal with conspirators who are desperate to exchange forbidden data and also desperate to hide; and because nobody else in law enforcement even wants to hear about it.
FCIC people tend to change jobs a lot. They tend not to get the equipment and training they want and need. And they tend to get sued quite often.
As the night wore on and a band set up in the bar, the talk grew darker. Nothing ever gets done in government, someone opined, until there's a DISASTER. Computing disasters are awful, but there's no denying that they greatly help the credibility of FCIC people. The Internet Worm, for instance. "For years we'd been warning about that—but it's nothing compared to what's coming." They expect horrors, these people. They know that nothing will really get done until there is a horror.

Next day we heard an extensive briefing from a guy who'd been a computer cop, gotten into hot water with an Arizona city council, and now installed computer networks for a living (at a considerable rise in pay). He talked about pulling fiber-optic networks apart.
Even a single computer, with enough peripherals, is a literal "network"—a bunch of machines all cabled together, generally with a complexity that puts stereo units to shame. FCIC people invent and publicize methods of seizing computers and maintaining their evidence. Simple things, sometimes, but vital rules of thumb for street cops, who nowadays often stumble across a busy computer in the midst of a drug investigation or a white-collar bust. For instance: Photograph the system before you touch it. Label the ends of all the cables before you detach anything. "Park" the heads on the disk drives before you move them. Get the diskettes. Don't put the diskettes in magnetic fields. Don't write on diskettes with ballpoint pens. Get the manuals. Get the printouts. Get the handwritten notes. Copy data before you look at it, and then examine the copy instead of the original.
Now our lecturer distributed copied diagrams of a typical LAN or "Local Area Network", which happened to be out of Connecticut. ONE HUNDRED AND FIFTY-NINE desktop computers, each with its own peripherals. Three "file servers." Five "star couplers" each with thirty-two ports. One sixteen-port coupler off in the corner office. All these machines talking to each other, distributing electronic mail, distributing software, distributing, quite possibly, criminal evidence. All linked by high-capacity fiber-optic cable. A bad guy—cops talk a about "bad guys" —might be lurking on PC #47 lot or #123 and distributing his ill doings onto some dupe's "personal" machine in another office—or another floor—or, quite possibly, two or three miles away! Or, conceivably, the evidence might be "data-striped"—split up into meaningless slivers stored, one by one, on a whole crowd of different disk drives.
The lecturer challenged us for solutions. I for one was utterly clueless. As far as I could figure, the Cossacks were at the gate; there were probably more disks in this single building than were seized during the entirety of Operation Sundevil.
"Inside informant," somebody said. Right. There's always the human angle, something easy to forget when contemplating the arcane recesses of high technology. Cops are skilled at getting people to talk, and computer people, given a chair and some sustained attention, will talk about their computers till their throats go raw. There's a case on record of a single question—"How'd you do it?"—eliciting a forty-five-minute videotaped confession from a computer criminal who not only completely incriminated himself but drew helpful diagrams.
Computer people talk. Hackers BRAG. Phone-phreaks talk PATHOLOGICALLY—why else are they stealing phone-codes, if not to natter for ten hours straight to their friends on an opposite seaboard? Computer-literate people do in fact possess an arsenal of nifty gadgets and techniques that would allow them to conceal all kinds of exotic skullduggery, and if they could only SHUT UP about it, they could probably get away with all manner of amazing information-crimes. But that's just not how it works—or at least, that's not how it's worked SO FAR.
Most every phone-phreak ever busted has swiftly implicated his mentors, his disciples, and his friends. Most every white-collar computer-criminal, smugly convinced that his clever scheme is bulletproof, swiftly learns otherwise when, for the first time in his life, an actual no-kidding policeman leans over, grabs the front of his shirt, looks him right in the eye and says: "All right, ASSHOLE—you and me are going downtown!" All the hardware in the world will not insulate your nerves from these actual real-life sensations of terror and guilt.
Cops know ways to get from point A to point Z without thumbing through every letter in some smart-ass bad-guy's alphabet. Cops know how to cut to the chase. Cops know a lot of things other people don't know.
Hackers know a lot of things other people don't know, too. Hackers know, for instance, how to sneak into your computer through the phone-lines. But cops can show up RIGHT ON YOUR DOORSTEP and carry off YOU and your computer in separate steel boxes. A cop interested in hackers can grab them and grill them. A hacker interested in cops has to depend on hearsay, underground legends, and what cops are willing to publicly reveal. And the Secret Service didn't get named "the SECRET Service" because they blab a lot.
Some people, our lecturer informed us, were under the mistaken impression that it was "impossible" to tap a fiber-optic line. Well, he announced, he and his son had just whipped up a fiber-optic tap in his workshop at home. He passed it around the audience, along with a circuit-covered LAN plug-in card so we'd all recognize one if we saw it on a case. We all had a look.
The tap was a classic "Goofy Prototype"—a thumb-length rounded metal cylinder with a pair of plastic brackets on it. From one end dangled three thin black cables, each of which ended in a tiny black plastic cap. When you plucked the safety-cap off the end of a cable, you could see the glass fiber—no thicker than a pinhole.
Our lecturer informed us that the metal cylinder was a "wavelength division multiplexer." Apparently, what one did was to cut the fiber-optic cable, insert two of the legs into the cut to complete the network again, and then read any passing data on the line by hooking up the third leg to some kind of monitor. Sounded simple enough. I wondered why nobody had thought of it before. I also wondered whether this guy's son back at the workshop had any teenage friends.
We had a break. The guy sitting next to me was wearing a giveaway baseball cap advertising the Uzi submachine gun. We had a desultory chat about the merits of Uzis. Long a favorite of the Secret Service, it seems Uzis went out of fashion with the advent of the Persian Gulf War, our Arab allies taking some offense at Americans toting Israeli weapons. Besides, I was informed by another expert, Uzis jam. The equivalent weapon of choice today is the Heckler & Koch, manufactured in Germany.
The guy with the Uzi cap was a forensic photographer. He also did a lot of photographic surveillance work in computer crime cases. He used to, that is, until the firings in Phoenix. He was now a private investigator and, with his wife, ran a photography salon specializing in weddings and portrait photos. At—one must repeat—a considerable rise in income.
He was still FCIC. If you were FCIC, and you needed to talk to an expert about forensic photography, well, there he was, willing and able. If he hadn't shown up, people would have missed him.
Our lecturer had raised the point that preliminary investigation of a computer system is vital before any seizure is undertaken. It's vital to understand how many machines are in there, what kinds there are, what kind of operating system they use, how many people use them, where the actual data itself is stored. To simply barge into an office demanding "all the computers" is a recipe for swift disaster.
This entails some discreet inquiries beforehand. In fact, what it entails is basically undercover work. An intelligence operation. SPYING, not to put too fine a point on it.
In a chat after the lecture, I asked an attendee whether "trashing" might work.
I received a swift briefing on the theory and practice of "trash covers." Police "trash covers," like "mail covers" or like wiretaps, require the agreement of a judge. This obtained, the "trashing" work of cops is just like that of hackers, only more so and much better organized. So much so, I was informed, that mobsters in Phoenix make extensive use of locked garbage cans picked up by a specialty high-security trash company.
In one case, a tiger team of Arizona cops had trashed a local residence for four months. Every week they showed up on the municipal garbage truck, disguised as garbagemen, and carried the contents of the suspect cans off to a shade tree, where they combed through the garbage—a messy task, especially considering that one of the occupants was undergoing kidney dialysis. All useful documents were cleaned, dried and examined. A discarded typewriter-ribbon was an especially valuable source of data, as its long one-strike ribbon of film contained the contents of every letter mailed out of the house. The letters were neatly retyped by a police secretary equipped with a large desk-mounted magnifying glass.
There is something weirdly disquieting about the whole subject of "trashing"—an unsuspected and indeed rather disgusting mode of deep personal vulnerability. Things that we pass by every day, that we take utterly for granted, can be exploited with so little work. Once discovered, the knowledge of these vulnerabilities tend to spread.
Take the lowly subject of MANHOLE COVERS. The humble manhole cover reproduces many of the dilemmas of computer-security in miniature. Manhole covers are, of course, technological artifacts, access-points to our buried urban infrastructure. To the vast majority of us, manhole covers are invisible. They are also vulnerable. For many years now, the Secret Service has made a point of caulking manhole covers along all routes of the Presidential motorcade. This is, of course, to deter terrorists from leaping out of underground ambush or, more likely, planting remote-control car-smashing bombs beneath the street.
Lately, manhole covers have seen more and more criminal exploitation, especially in New York City. Recently, a telco in New York City discovered that a cable television service had been sneaking into telco manholes and installing cable service alongside the phone-lines—WITHOUT PAYING ROYALTIES. New York companies have also suffered a general plague of (a) underground copper cable theft; (b) dumping of garbage, including toxic waste, and (c) hasty dumping of murder victims.
Industry complaints reached the ears of an innovative New England industrial-security company, and the result was a new product known as "the Intimidator," a thick titanium-steel bolt with a precisely machined head that requires a special device to unscrew. All these "keys" have registered serial numbers kept on file with the manufacturer. There are now some thousands of these "Intimidator" bolts being sunk into American pavements wherever our President passes, like some macabre parody of strewn roses. They are also spreading as fast as steel dandelions around US military bases and many centers of private industry.
Quite likely it has never occurred to you to peer under a manhole cover, perhaps climb down and walk around down there with a flashlight, just to see what it's like. Formally speaking, this might be trespassing, but if you didn't hurt anything, and didn't make an absolute habit of it, nobody would really care. The freedom to sneak under manholes was likely a freedom you never intended to exercise.
You now are rather less likely to have that freedom at all. You may never even have missed it until you read about it here, but if you're in New York City it's gone, and elsewhere it's likely going. This is one of the things that crime, and the reaction to crime, does to us.
The tenor of the meeting now changed as the Electronic Frontier Foundation arrived. The EFF, whose personnel and history will be examined in detail in the next chapter, are a pioneering civil liberties group who arose in direct response to the Hacker Crackdown of 1990.
Now Mitchell Kapor, the Foundation's president, and Michael Godwin, its chief attorney, were confronting federal law enforcement MANO A MANO for the first time ever. Ever alert to the manifold uses of publicity, Mitch Kapor and Mike Godwin had brought their own journalist in tow: Robert Draper, from Austin, whose recent well-received book about ROLLING STONE magazine was still on the stands. Draper was on assignment for TEXAS MONTHLY.
The Steve Jackson/EFF civil lawsuit against the Chicago Computer Fraud and Abuse Task Force was a matter of considerable regional interest in Texas. There were now two Austinite journalists here on the case. In fact, counting Godwin (a former Austinite and former journalist) there were three of us. Lunch was like Old Home Week.
Later, I took Draper up to my hotel room. We had a long frank talk about the case, networking earnestly like a miniature freelance-journo version of the FCIC: privately confessing the numerous blunders of journalists covering the story, and trying hard to figure out who was who and what the hell was really going on out there. I showed Draper everything I had dug out of the Hilton trashcan. We pondered the ethics of "trashing" for a while, and agreed that they were dismal. We also agreed that finding a SPRINT bill on your first time out was a heck of a coincidence.
First I'd "trashed"—and now, mere hours later, I'd bragged to someone else. Having entered the lifestyle of hackerdom, I was now, unsurprisingly, following its logic. Having discovered something remarkable through a surreptitious action, I of course HAD to "brag," and to drag the passing Draper into my iniquities. I felt I needed a witness. Otherwise nobody would have believed what I'd discovered....
Back at the meeting, Thackeray cordially, if rather tentatively, introduced Kapor and Godwin to her colleagues. Papers were distributed. Kapor took center stage. The brilliant Bostonian high-tech entrepreneur, normally the hawk in his own administration and quite an effective public speaker, seemed visibly nervous, and frankly admitted as much. He began by saying he consided computer-intrusion to be morally wrong, and that the EFF was not a "hacker defense fund," despite what had appeared in print. Kapor chatted a bit about the basic motivations of his group, emphasizing their good faith and willingness to listen and seek common ground with law enforcement—when, er, possible.
