FBI Nabs Chicago Transit Authority Radio Hacker

Wh15per writes "The Chicago FBI Joint Terrorism Task Force arrested an individual for misusing Chicago Transit Authority radio systems. Marcel Carter, 20, is charged with violating a US code that forbids interference with transportation operators. A federal complaint alleges he began using a radio to transmit on CTA frequencies in June 2008, often interjecting comments during communications between the agency's control center and train operators. The CTA claims Carter's radio communications were never followed, and passengers were never in danger."

    Well, partly because if you upgrade all aviation comms to encrypted radios, then every pilot would need to go out and upgrade their equipment to an encrypted unit. Which then means that encrypted radios need to become readily available for every pilot and/or A&P mechanic to purchase, which means every Tom, Dick, and Harry can walk into Ye Olde Pilot Shoppe and buy one, which means that said Tom, Dick, or Harry can then carry on with their mischief. You'd in essence be forcing everyone in the Aviation field who uses comms for anything to upgrade their gear and not improving anything as a result.

    Now, with a closed-loop internal system like bus and train, I see your point. You have a fixed number of authorized users, and life is good. Mischief would be limited to a hacker who has the time and resources to monitor the frequencies long enough to break the encryption (which wouldn't be terribly long, since all the radios would have to use the same encryption keys, but at least the infantile idiots who buy a GPRS radio at WalMart and have trouble inserting the batteries properly would be excluded - so when someone DOES break in they'll celebrate their achievement by something more sophisticated than yelling "AFLAC" in a falsetto duck voice every ten seconds).

Heck, I'd think using the cellular network would give them more secure communications with better voice quality and less need to maintain expensive radio towers.

    No, many planes are equipped with multiple radios (for backup or simply to be able to switch frequencies quickly) anyway.

    The real issues are threefold:

    1. Money: Encrypted radios cost, and there are a LOT of the old AM-band radios out there that would need to be replaced. Most planes have one, and most pilots carry at least one handheld for emergency backup and to get ATIS and just to monitor the frequency while they are preflighting to get an idea of what traffic is like, etc.
    2. Range: With an AM, unencrypted radio, you can lose a surprising amount of signal and still make out what the person on the other end is saying. Once you encrypt the signal, your signal has to be pretty close to perfect or the decryption doesn't work. So you either just cost radios serious amounts of range, or you have to find a new frequency band where more information can be packed into the same frequency and you have more discrete frequencies to ensure a clear transmission free of interference.
    3. Security: In order to use them, pilots will need to purchase them. So every pilot shop is going to need to offer these radios for easy sale. If pilots can buy them, so can other people, unless you want to get into a registration system as complex and useless as a gun ownership database. Then, of course, you can't really issue unique encryption keys to each radio because registering them is going to require a hellishly complex system.

          I'll give you the brief rundown of their case.

          My car was traveling at 141 miles per hour on a narrow limestone road. In my attempts to kill the prosecutions witness, I came over a hill in front of his house, and flew my car 58 feet. After landing, I traveled an additional 500 feet, and made a 90 degree turn. The police, who happened to be sitting in his front yard, but did not have any measuring equipment, followed me for approx 1 mile and stopped me.

          Now for the impossible parts.

          The car was rather heavy, and had a small engine. It wasn't capable of 85mph, much less 141mph.

          Based on the slope of the hill, 141mph would have been insufficient for a car to jump that distance. I would have needed to be doing closer to 300mph. To have done it at 141, there must have been other provisions, such as anti-gravity. (ha!)

          It had crappy 2 ply tires. They were cheap, but did the job of making the car travel at normal speeds. They couldn't have survived the claimed nor required speeds nor the landing of this flying car.

          The 90 degree turn, which was 500 feet from where they claimed the incident happened, had a tree in the middle of the road, and a ditch on the other side. Once making the turn, which at 141mph on a rock road would have been impossible, there's no way I would have navigated between the tree and the ditch.

          Their witness said I did the same thing every day.

          So I guess I did the impossible every day.

          I was arrested. My PASSENGER was arrested, because he was in the car. At the first hearing, the prosecution demanded that I was to be held in custody, as I was a flight risk (I obviously can fly), and a danger to the general public, as I was trying to kill people. What could have been a simple speeding ticket for 10mph over the speed limit became over a year working through the court system until it was finally thrown out.

          The only thing about the whole case that I liked was that I met the two officers. They were both arrested and convicted on a whole variety of charges including falsifying information and corruption. But, that was years later and had nothing to do with my case.

          You can get arrested on the most BS charges. You will likely go through the system on the BS charges. Unless you can afford a good lawyer, your public defender will tell you to take a plea deal for some slightly lesser charges.

          It's all in who you, or someone you know, pisses off. How was I to know that the old man who lived on top of the hill didn't like people driving by his house, on a public road? He apparently sat in his house and would curse at cars driving by on "his" road.

          In the end, I guess he got his way. I never drove down "his" road again. I very intentionally took an alternate route, so I'd never have to deal with that again.

    You really need to get a grip on the difference between "interference with a mass transport system" and "being obnoxious". Or don't, and continue to whine about how the Patriot Act ruins your life because it makes everything you do illegal, and look stupid when you tell people exactly what you're doing that you think is illegal. No, "yelling at a bus driver" isn't. "Putting pennies on a train track" isn't. "Interfering with mass transport communications and safety systems" is.

    1. Money: Encrypted radios cost,
    3. Security: In order to use them, pilots will need to purchase them. So every pilot shop is going to need to offer these radios for easy sale. If pilots can buy them, so can other people, unless you want to get into a registration system as complex and useless as a gun ownership database. Then, of course, you can't really issue unique encryption keys to each radio because registering them is going to require a hellishly complex system. So you'll end up with something that is easily replicated and easily acquired, and therefore offers no real security.

    Well, no.

    Cell phones are encrypted radios, too, yet they are cheap and plentiful.

    Cell phones have to be registered and assigned to an owner (it has to be, otherwise the cellphone company could not bill users), and in case of theft, it can be remotely disabled.

    My point here is that I do not see a reason why public transportation systems still rely on decades-old, non-encrypted technology. With ATC, it's a trivial matter of ordering a handheld on-line that is capable of transmitting on all ATC freqs. Agencies that continue to rely on antiquated systems deserve part of the blame.

    There are three major reasons: interoperability, reliability, and expense.

    Different areas have different needs, and that inevitably means that not every system will work with every other system. For a closed system like a subway this may not matter so much but in most other cases it's very important. And it's very hard to anticipate who's "allowed" to speak to who. The common denominator is unencrypted analog.

    Digital systems do not degrade gracefully. A partial or garbled radio transmission may at least be of some use. A weak burst of data that no one hears is of no use at all.

    Radio systems are very expensive and tricky things to get right. Not only is there the cost of replacing all that perfectly good equipment, there's the cost of transmitters, repeaters, towers, and planning. Fire and police often listen in at home or in their personal vehicles, too, so you have to factor in that cost as well.

    There's also one other reason that's often forgotten or deliberately obscured by the authorities, and that's public access and accountability. Railfans and aviation enthusiasts listen in on this stuff all the time, and there have been cases where their own personal records have been useful in determining the causes of accidents. Same goes for non-transportation radio transmissions from police, fire, and more mundane stuff like construction crews and snowplows (Where are the worst icing conditions? Are they anywhere near my road yet?)

    It's useful stuff for people to be able to hear and there's no good reason for all of it to be kept secret just on the off-chance someone steals a radio.

    But he did succeed in causing quite a bit of frequency interference: ATC still operates on AM, so there is no "capture" effect as with FM, where the strongest station overrides weaker stations. Simultaneous transmissions are garbled, so "Say again" becomes a very automatic response in those situations (hell, I still use that phrase today...old habits die hard).

    You *DO* realize that's why aviation still uses AM, right? The FM capture effect, when it happens, happens spontaneously, and there's no way to know it's happening. If you "step on" someone on the FM band, it's possible to just continue on with a very wierd instruction. And given that a plane may be in-between you and the one you're talking to, someone may get a garbled transmission that gets dangerous. Unless you catch the fact that the voice changes, you'll never know.

    On AM, you'll get the warble, which basically means the transmission gets stepped on and alerts everyone to the collision. (Sometimes, the ATC tower is just powerful enough that even stepped on, you can make out what's being said). But the FM capture effect is very dangerous since the "most powerful signal" can be the plane flying beside you.

    If your idiot was standing near the runway, he could easily send a "cleared to takeoff" that's only heard by that pilot, while ATC is sending "cleared to land" to the plane in the air.
