I've done a little work to pull some noise out of the audio, but I may have made it worse in some spots. Thanks go out to the Phreaknic 12 A/V team SomeNinjaMaster, Night Carnage, Greg, Brimstone, Poiu Poiu, Mudflap, and Drunken Pirate for setting up the rigs and capturing the video.

"We must treat every suspicious item the same and utilize the tools we have available to make a final determination," said Federal Security Director David Wynn. "Procedures are in place for a reason and this is a clear indication our workforce is doing a great job."

My guess is that if Kip Hawley were allowed to comment on my blog, he would say something like this: "It's not just bombs that are prohibited; it's things that look like bombs. This looks enough like a bomb to fool the other passengers, and that in itself is a threat."

Okay, that's fair. But the average person doesn't know what a bomb looks like; all he knows is what he sees on television and the movies. And this rule means that all homemade electronics are confiscated, because anything homemade with wires can look like a bomb to someone who doesn't know better. The rule just doesn't work.

And in today's passengers-fight-back world, do you think anyone is going to successfully do anything with a fake bomb?

OnStar will soon include the ability for the police to shut off your engine remotely. Buses are getting the same capability, in case terrorists want to re-enact the movie Speed. The Pentagon wants a kill switch installed on airplanes, and is worried about potential enemies installing kill switches on their own equipment.

Microsoft is doing some of the most creative thinking along these lines, with something it's calling "Digital Manners Policies." According to its patent application, DMP-enabled devices would accept broadcast "orders" limiting capabilities. Cellphones could be remotely set to vibrate mode in restaurants and concert halls, and be turned off on airplanes and in hospitals. Cameras could be prohibited from taking pictures in locker rooms and museums, and recording equipment could be disabled in theaters. Professors finally could prevent students from texting one another during class.

The possibilities are endless, and very dangerous. Making this work involves building a nearly flawless hierarchical system of authority. That's a difficult security problem even in its simplest form. Distributing that system among a variety of different devices -- computers, phones, PDAs, cameras, recorders -- with different firmware and manufacturers, is even more difficult. Not to mention delegating different levels of authority to various agencies, enterprises, industries and individuals, and then enforcing the necessary safeguards.

Once we go down this path -- giving one device authority over other devices -- the security problems start piling up. Who has the authority to limit functionality of my devices, and how do they get that authority? What prevents them from abusing that power? Do I get the ability to override their limitations? In what circumstances, and how? Can they override my override?

How do we prevent this from being abused? Can a burglar, for example, enforce a "no photography" rule and prevent security cameras from working? Can the police enforce the same rule to avoid another Rodney King incident? Do the police get "superuser" devices that cannot be limited, and do they get "supercontroller" devices that can limit anything? How do we ensure that only they get them, and what do we do when the devices inevitably fall into the wrong hands?

It's comparatively easy to make this work in closed specialized systems -- OnStar, airplane avionics, military hardware -- but much more difficult in open-ended systems. If you think Microsoft's vision could possibly be securely designed, all you have to do is look at the dismal effectiveness of the various copy-protection and digital-rights-management systems we've seen over the years. That's a similar capabilities-enforcement mechanism, albeit simpler than these more general systems.

And that's the key to understanding this system. Don't be fooled by the scare stories of wireless devices on airplanes and in hospitals, or visions of a world where no one is yammering loudly on their cellphones in posh restaurants. This is really about media companies wanting to exert their control further over your electronics. They not only want to prevent you from surreptitiously recording movies and concerts, they want your new television to enforce good "manners" on your computer, and not allow it to record any programs. They want your iPod to politely refuse to copy music a computer other than your own. They want to enforce their legislated definition of manners: to control what you do and when you do it, and to charge you repeatedly for the privilege whenever possible.

"Digital Manners Policies" is a marketing term. Let's call this what it really is: Selective Device Jamming. It's not polite, it's dangerous. It won't make anyone more secure -- or more polite.

From Seattle Times Newspaper:

Never underestimate the tenacity of a 19-year-old. When Kait Duplaga of White Plains, N.Y., had her laptop stolen — along with electronics she and her roommates owned — she didn’t despair. She cleverly used a built-in piece of Mac OS X 10.5 (Leopard) technology to catch the alleged thieves.

Duplaga, an Apple Store employee, had turned on Back to My Mac on her computer. This Leopard feature allows remote access to a computer when the right network conditions are met. A few days after her computer was stolen, a friend of Duplaga’s spotted her in iChat, and sent her a text message by cellphone congratulating her on the computer’s return.

The machine’s current possessor wasn’t aware that Duplaga stayed logged in to iChat, and so she showed up there.

She logged in to .Mac on another computer (via the .Mac system preference pane), and used the built-in screen sharing to access her purloined laptop. Screen sharing provides both a view of the remote screen as well as control of the keyboard and mouse.

Ozmo apparently is trying to leverage the ubiquity of Wi-Fi, the market reach of Intel (which has invested in the firm and is pushing its technology), and the dissatisfaction with Bluetooth device association and throughput to stick a wedge into Bluetooth's market domination. Well over a billion Bluetooth chipsets have shipped--CSR alone has shipped over a billion--and estimates put half a billion this year into cell phones alone. So there's a large embedded market to overcome.

This new technology, so far unnamed but apparently part of Intel's Cliffside research program, is trying to reduce complexity by reducing the number of standards needed to drive a computer, while increasing the flexibility of those standards. Ozmo and Intel's system would, for instance, allow a simultaneous WLAN connection and a PAN network of up to 8 devices using a single radio on a computer.

The press releases and articles make it quite unclear whether a new Wi-Fi chip would be needed; that chip would almost certainly not conform to today's Wi-Fi standards except in a compatibility mode, given that Wi-Fi has no capacity for PAN-style connections. Ad hoc mode isn't quite the same thing. In the past, extensions to the 802.11 standards that are the basis of the Wi-Fi certification and service mark were allowed as long as basic 802.11 worked as expected.

Bluetooth and Wi-Fi have been complementary technologies for several years. There were early conflicts--I wrote an article about the severe problems in using Bluetooth 1.1 and 802.11b back in 2001! But those interference and coordination issues were resolved, and Blueooth and Wi-Fi marched forward hand in hand, without any close association between the two trade groups behind the standards and branding, but with a lot of technology acquisitions and mergers on the part of companies that make Wi-Fi gear.

The Bluetooth SIG has been working for years to put Bluetooth on top of ultrawideband (UWB), which is still not readily available in the marketplace. UWB is always next year's big technology, and may be passed by except for applications like high-definition video streaming among a/v electronics. The SIG also announced support in Oct. 2007 for Bluetooth + 802.11, where a Bluetooth device could initiate high-speed transfers using 802.11 (yes, Wi-Fi, but not by that name; no partnership there). Bluetooth plus UWB is likely not available until 2009 at this point; BT and Wi-Fi, not until perhaps 2010. (See my article, "Bluetooth to Add Wi-Fi with UWB Delays in Mind," 2007-10-31.)

It's hard to see how Ozmo builds a place in this infrastructure, even with higher bandwidth, and what Ozmo says is lower power use and a lower cost for their chips, because laptop and desktop makers will need to buy into the Intel/Ozmo ecosystem. The demand for this kind of technology is typically driven by users who buy one component and need their computer to interface with it.

With Ozmo and Intel apparently planning to debut the Wi-Fi chips and driver support next year, it seems like a multi-year process to figure out whether Ozmo can evolve a competitive position to Bluetooth, even as Bluetooth is estimated to be embedded in over 1.2b cell phones by 2012.

But two weeks ago a jury in the civil lawsuit against that employer, NDS Group, largely cleared the company -- and by extension Tarnovsky -- of piracy, finding NDS guilty of only a single incident of stealing satellite signals, for which Dish was awarded $1,500 in damages.

"I knew this was going to come," Tarnovsky says. "They didn't have any proof or evidence."

The trial was years in the making, yet raised more questions than it answered. It came down to testimony between admitted pirates on both sides who accused each other of lying. Now that it's over Tarnovsky, who was fired by NDS last year, is eager to tell his side of the story.

Dressed in loose jeans, flip-flops and a T-shirt, Tarnovsky, 37, spoke with Wired.com by phone and in an air-conditioned lab in Southern California where he's been running a consultancy since losing his job. Surrounded by boxes of smart cards and thousands of dollars worth of microscopes and computers used for researching chips, he talked excitedly at lightning speed about his strange journey, which began in a top-secret Pentagon communications center, and ended with him working both sides of a heated electronic war over pay TV.

His story sheds new light on the murky, morally ambiguous world of international satellite pirates and those who do battle with them.

The stakes are high: Earnings in the satellite-TV industry reach the billions. In the first quarter of this year alone, U.S. market leader DirecTV announced revenue of $4.6 billion from more than 17 million U.S. subscribers. Dish Network earned $2.8 billion from nearly 14 million subscribers. Although satellite piracy has greatly diminished from its peak seven to 10 years ago when the events detailed in the civil lawsuit took place, the two companies lost millions in potential revenue, and spent millions more to replace insecure smart cards used in their systems and track down dealers selling pirated smart cards.

Those smart cards are at the center of the controversy over NDS, a British-Israeli company and a majority-owned subsidiary of Murdoch's News Corp. The company makes access cards used by pay-TV systems, most prominently DirecTV -- itself a former Murdoch company. Nagrastar, a plaintiff in the case and NDS's chief competitor, makes access cards used by Dish Network and other runners-up in the market.

According to allegations in the lawsuit, in the late '90s NDS extracted and cracked the proprietary code used in Nagrastar's cards, a fact that NDS doesn't contest. What happened next, though, is hotly disputed. Nagrastar says Tarnovsky used the code to create a device for reprogramming Nagrastar cards into pirate cards, and gave the cards to pirates eager to steal Dish Network's programming. Tarnovsky was also accused of posting to the internet a detailed road map for hacking Nagrastar's cards.

Nagrastar says NDS had an obvious motive for these antics: Their own chip, the so-called P1 or "F Card," had already been thoroughly cracked by pirates, and the company wanted to level the playing field with its competitors.

NDS denied the allegations at trial. The company declined to comment for this article or to confirm details of Tarnovsky's employment other than to say it was pleased that the verdict "ended in a resounding affirmation of NDS and its business ethics and proper conduct."

Tarnovsky began his pirating career in the '90s while serving in the U.S. Army. He had a top-secret SCI security clearance working on cryptographic computers in Belgium for NATO headquarters, and spent a year at Ft. Detrick in Maryland providing support to the National Security Agency for satellite transmissions to Europe.

In 1996, he was stationed in Germany when his colonel sold him a used satellite-TV system, along with two pirated access cards, neither of which worked. Tarnovsky began posting on online pirate forums, and developed contacts in the community, ultimately learning how to fix the cards to access English-language programs from Sky in the United Kingdom.

After leaving the Army and returning to the States, he got a call from Ron Ereiser, a Canadian pirate who'd heard about him through the grapevine. Pirates had found a back door in the P1 card and were vigorously exploiting it to get DirecTV content. But the cards kept failing. In a game of pirate pingpong, DirecTV periodically deployed electronic countermeasures, or ECMs, in the satellite stream that killed the cards in their set-top boxes. Ereiser needed someone to fix the cards.

There was serious black-market money on the line. In Canada, where pirating of U.S. satellite services wasn't considered illegal until 2002, syndicates of dealers did enough business that they could afford to chip in about $50,000 to hire a programmer to reverse engineer the latest cards. Pirate cards would sell for about $200 each, with the profit split between the investors and engineers. Tarnovsky claims Canadian pirate dealers could make $400,000 in a weekend; when Reginald Scullion, a notorious pirate in Canada, was raided in 1998, authorities seized $5.5 million from his bank accounts and safe-deposit boxes, though not all of it was from piracy.

Ereiser, who now works as a consultant to Nagrastar, concedes that the money from piracy was good, but insists that nobody became an overnight millionaire. "It was lucrative," he said in a telephone interview. "But to suggest that millions were being made in a month is an absolute crock."

DirecTV's countermeasures were a nagging drag on this lucrative trade. Every time an ECM was deployed, Ereiser and other dealers would be harangued by customers demanding to have the cards fixed and their TV programs restored.

Tarnovsky, who was known online as "Big Gun," says Ereiser offered him $20,000 to fix cards that were killed by ECMs, and he agreed. Each time NDS created a countermeasure, Tarnovsky would analyze the code and find a way to circumvent the countermeasure. He did it while working full-time as a software engineer for a semiconductor company in Massachusetts.

"I'd be at work and I'd check the IRC (channel) to see if they'd launched their Thursday countermeasure yet," he says. "It was like a chess game for me. I couldn't wait for them to do a countermeasure because I would counter it in minutes."

Tarnovsky suffers from attention deficit hyperactivity disorder, which he says helped with the detailed work.

"I think so fast," he says.

It wasn't long before NDS came courting. Tarnovsky had a contact at the company to whom he'd begun passing information about holes in its software, even supplying patches to fix them. NDS offered him a job earning $65,000 a year. By the time the company fired him last year, he was earning about $245,000 in salary and bonuses and had another $100,000 in stock options, he says.

The company set him up in a lab in Southern California equipped with a computer, some DirecTV set-top boxes, sample DirecTV cards and NDS source code. There was no fancy equipment at first, but his relationship with NDS and the lab grew over the decade he worked with them. Tarnovsky says the job was a dream come true. While living in Europe he'd once seen a news report showing an engineer at a French satellite company writing countermeasures, sitting in a lab with smart cards piled around him on his desk.

"I always thought it would be so cool to be that guy," Tarnovsky says. "Finally I got the chance."

Tarnovsky had two roles at NDS -- to find holes in its software and work undercover with pirates to discover what they were doing against NDS technology.

To conceal his relationship with NDS from pirates, few people at the company knew his identity. He used the name "Michael George" and for the first four years was paid through other companies, including, for about five months, HarperCollins, the Murdoch-owned book publisher.

"It was very hush-hush, because we didn't know who could be an inside informant," he says.

Part of his job was developing ECMs for NDS. He'd examine pirate NDS cards to determine how they worked, then send instructions to engineers in Israel to create a kill for them.

"I didn’t actually load the gun and pull the trigger but I got to make the bullet," Tarnovsky says.

Among the countermeasures he says he created was one known among pirates as the "Black Sunday" kill -- an elaborate scheme that destroyed tens of thousands of pirate DirecTV cards a week before Super Bowl Sunday in 2001.

Instead of being delivered all at once like other measures, the Black Sunday attack code was sent to pirate cards in about five dozen parts over the course of two months, like a tank transported piece by piece to a battlefield to be assembled in the field. "They never expected us to do this," Tarnovsky says.

The kill didn't last long before pirates found a way to jump-start the cards. But it holds an enduring position in pirate lore; for the first time, they could see a cunning mind at work on the other side.

While Tarnovsky was killing cards, however, he was also helping pirates fix them.

Days before Tarnovsky began working for NDS, the company began phasing in its latest-generation smart card, the P2, which was thought to be virtually uncrackable. But word reached the company that two Bulgarian hackers working for Ereiser had cracked the P2. On NDS's instructions, Tarnovsky met with Ereiser undercover in Calgary to get the code. When he got there, Ereiser offered him $20,000 to work for him fighting whatever countermeasures NDS and DirecTV cooked up to thwart their P2 hack.

NDS considered it a great opportunity for Tarnovsky to maintain his pirate identity, but DirecTV insisted on some controls. Under "Operation Johnny Walker," as they dubbed it, Tarnovsky gave Ereiser a program to create pirate NDS cards, but encrypted it so no one could copy it. The program worked only with a dongle attached to Ereiser's computer and created a limited number of cards that could be killed at any time.

But, according to Nagrastar, Tarnovsky wasn't just helping NDS fight piracy by working undercover and creating ECMs, he was also committing piracy against NDS's competitors to weaken their place in the market.

After NDS engineers in Israel hacked the Nagrastar code in the late '90s, Nagrastar says Tarnovsky created a "stinger" program that turned Nagrastar cards into pirate cards. He allegedly gave the program to a Canadian named Al Menard in 1999 who sold reprogrammed Nagrastar cards for $350 each. Then in December 2000, someone anonymously posted code and detailed instructions for hacking Nagrastar's card to two websites, one of them run by Menard, exposing Dish Network to even more piracy. It was estimated in court testimony that between 100,000 and 165,000 pirated Nagrastar cards were released to the market in the wake of this posting.

Nagrastar says Menard began sending Tarnovsky cash from the sale of the pirate cards. At the end of August 2000, authorities acting on an anonymous tip seized two boxes destined for a mail drop Tarnovsky rented in Texas. Inside, they found a CD and DVD player with $20,000 and $20,100 concealed inside.

The boxes were sent from a phony address for "Regency Audio" in Vancouver to C.T. Electronics at Tarnovsky's address. A customs form for a third package that wasn't seized indicated that it was sent from Menard to Tarnovsky and also contained electronic goods.

Tarnovsky was in Israel at the time, and says he didn't know anything about the packages until he was notified that they'd been seized. He thinks they were sent by someone in Nagrastar's camp who was trying to frame him. He says Nagrastar's accusations about the "stinger" program were baseless, and that he never gave Menard any software.

On Feb. 9, 2001, U.S. Customs agents appeared at his doorstep. On advice of a lawyer, he declined to let them search his house without a warrant. Tarnovsky was never arrested or charged with any crime, but suspicions against him were mounting. NDS gave Tarnovsky a polygraph test, but asked only two, self-interested questions that never touched on the Nagrastar accusations: Had Tarnovsky sold any modified NDS smart cards, or company secrets, since he'd been working for the company? Tarnovsky answered no, and passed the test.

He continued to work for NDS for six years. But then last year, Nagrastar confronted NDS with a sheriff's report showing that fingerprints lifted from the seized electronics equipment sent to Tarnovsky's Texas mail drop belonged to an associate of Menard, raising suspicions again that Tarnovsky might have sold pirate Nagrastar cards without NDS's knowledge. NDS fired him.

Tarnovsky says his termination proves he and NDS weren't conspiring against Nagrastar. Had they been, NDS would have done anything to keep him happy, and quiet. He says the fact that Nagrastar lost the case shows he wasn't pirating on his own either.

"I've never sold a single Nagra card, ever," he says.

Although he was angry at NDS for abandoning him, he told Wired.com before the trial ended that he hoped to work for the company again.

"I want to make sure that NDS wins this lawsuit because that will clear my name," he said at the time.

When it was suggested that someone might view this as motivation for him to lie on NDS's behalf, he disagreed.

"That's crazy. I could go to jail," he said. "I would never perjure myself for some company."

Since NDS fired him he's been consulting for two semiconductor companies and a manufacturer of dongle tokens, but he misses his life in electronic warfare. If NDS doesn't want him, he says he'd be happy to work for Nagrastar -- jumping sides once again.

"I could design a whole entire chip for them like I did for NDS," he says. "NDS thinks today that their technology is superior to everybody else's and it probably is, because they're 17 years ahead of Nagra technologically. But Nagra could catch up overnight if they used my services.

"I'm a very valuable asset as far as smart-card technology goes," he adds. "I know everything about (NDS) as far as their intellectual property models go."

He offered his services to the company last year, while the lawsuit was pending. Nagrastar declined.
