Neal Stephenson - Cryptonomicon

“Bruce!” Randy shouts.

Bruce falters and looks over in Randy's direction. “Randy,” he says.

“Why are you here?”

“Word on the street is that the Feds were raiding Ordo,” Bruce says.

“Interesting… any particular Feds?”

“Comstock,” Bruce says. Meaning Paul Comstock, who, by virtue of being Attorney General of the United States, runs the FBI. Randy does not believe this rumor, but in spite of himself he scans the area for people fitting the general profile of FBI agents. The FBI hates and fears strong crypto. Meanwhile another Secret Admirer type shouts, “I heard Secret Service!” Which is even creepier, in a way, because the Secret Service is part of the Treasury Department, and is charged with combating wire fraud and protecting the nation's currency.

Randy says, “Would you be open to the possibility that it's all a Net rumor? That what's really going on is that a piece of equipment inside Ordo's offices is being seized as part of a legal squabble?”

“Then why are all these cops here?” Bruce says.

“Maybe the masked men with assault rifles drew them.”

“Well, why did the Secret Admirers show up in the first place if it wasn't a government raid?”

“I don't know. Maybe it's just some kind of spontaneous self-organizing phenomenon—like the origin of life in the primordial soup.”

Bruce says, “Isn't it just as possible that the legal squabble is a pretext?”

“In other words that the squabble is sort of like a Trojan horse put together by Comstock?”

“Yeah.”

“Knowing all of the parties involved, I'd rate it as unlikely,” Randy says, “but let me think about it.”

The noise and intensity of the argument in the Ordo parking lot spike upwards. Randy looks at the video window, which unfortunately has no sound track. The transactions between frames come as isolated blocks of new pixels slapped up one at a time over the old, like a large billboard being posted sections. High-definition TV it ain't. But Randy definitely recognizes Avi, standing there tall, pale, and calm, flanked by one guy who's probably Dave the Ordo president, and another guy who's obviously a lawyer. They are literally standing in the doorway of the building and facing off against two cops and none other than Andrew Loeb, who is in rapid motion and hence poses an insurmountable bandwidth problem. The Internet video gear is smart enough not to mess with parts of an image that aren't changing very much, and so the planted cops get refreshed maybe a couple of times a minute, and then just in a few rectangular image-shards. But Andrew Loeb is waving his arms around, hopping up and down, lunging towards Avi from time to time, pulling back and taking calls on his cellphone, and waving documents in the air. The computers have identified him as a bunch of pixels that require a great deal of attention and bandwidth, and so somewhere some poor algorithm is churning through the high-pressure slurry of compressed pixels that is the image of Andrew Loeb, and doing its level best to freeze the most rapidly-moving parts into discrete frames and chop them up into checkerboard-squares that can be broadcast as packets over the Net. These packets arrive in Randy's computer as the radio network passes them along, i.e., sporadically and in the wrong order. So Andrew Loeb appears as a cubist digital-video artifact, a rectilinear amoeba of mostly trench-coat-beige pixels. From time to time his eyes or his mouth will suddenly appear, disembodied, in the center of an image-block, and remain frozen there for a few seconds, crystallized in a moment of howling rage.

This is weirdly mesmerizing until Randy's startled out of his reverie by a clunk. He looks over to see that the van he's blocked in wasn't abandoned after all; it was full of Dwarves, who have now thrown the back doors open to reveal a nest of cables and wires. A couple of the Dwarves are heaving a boxy apparatus up onto the roof of the van. Cables run out of it to another boxy apparatus down below. The apparatus is electrical in nature—and doesn't appear capable of firing projectiles—so Randy decides not to pay it much attention for the moment.

Voices well up across the street. Randy sees some cops climbing out of a cop-van carrying a battering ram.

Randy types:

randy

and hits the return key. Tombstone answers:

password:

and Randy types it in. Tombstone informs him that he's logged on, and that he has mail.

The fact that Randy has logged on has now been recorded by the system in several locations on the hard drive. He has, in other words, just slapped big greasy fingerprints all over a weapon that the police are moments away from seizing as evidence. If Tombstone is shut down and grabbed by the cops before Randy can erase those traces, they will know he has logged on at the very moment that Tombstone was confiscated, and will put him in prison for tampering with evidence. He very much wishes that Douglas MacArthur Shaftoe could somehow be made aware of what a ballsy thing he is doing here. But then Doug has probably done all kinds of ballsy things of which Randy will never be aware, and Randy respects him anyway because of his bearing. Maybe the way to get that kind of bearing is to go around doing ballsy things in secret that somehow percolate up to the surface of your personality.

Randy could just reformat the hard drive with a single command, but (1) it would take several minutes to execute and (2) it would not thoroughly erase the incriminating bits, which could be lifted from the hard drive by a motivated technician. Because he knows which files have recorded his log-on, he executes a command that finds those files on the hard drive. Then he types another command that causes random numbers to be written over those areas of the hard drive seven times in a row.

The cops are slamming the battering ram against the side door of the office building when Randy's right pinky slams the Enter key and executes that command. He is almost certainly safe from the tampering-with-evidence charge now. But he hasn't actually tampered yet, which is the whole point of this exercise. He needs to find all the copies of the e-mail message that specifies the latitude and longitude of the wreck, and do the same multiple-erase trick on them. If the damn things were not encrypted, he could search for the critical strings of digits. As it is, he will have to search for files that were created during a certain time period, around the time that Randy was out on Glory, anchored over the wreck. Randy knows roughly what day that was, and so he sets the limits of the search to give him any files created five days either side of that, just to be safe, and limits it to only those directories used for e-mail.

The search takes forever, or maybe it just seems that way because the cops have smashed the side door off its hinges now and are inside the building. The video window catches Randy's eye as it changes dramatically; he gets a veering montage of grainy frozen images of a room; a doorway; a hallway; a reception area; and finally a barricade. The Ordo guys have yanked their video camera out of the window and restationed it at their front desk, recording a barrier built of cheap modular office furniture piled against the glass entrance to the reception. The camera tilts up to show that one of the four glass door slabs has already been crystallized by (one supposes) the impact of the battering ram.

Randy's “find” command finally returns with a list of about a hundred files. The half-dozen or so critical ones are on the list somewhere, but Randy doesn't have time to go through the list figuring out which is which. He has the system generate a list of the disk blocks occupied by those files, so that he can go back later and do a super-erase. Once he's got that information, he does a “rm” or “remove” command on all of them. This is a paltry and miserable way to expunge secrets from a hard drive, but Randy's afraid he may not have time to do it more thoroughly. The “rm” only takes a few moments and then Randy goes back and has the system write random numbers on top of those disk blocks seven times in a row, just as he did earlier. By this time the barricade has been scattered all over Ordo's lobby and the cops are inside. They have weapons drawn and pointed at the ceiling and they don't look very happy.
