California's Wireless Road Tolls Easily Hackable

timothy posted about 6 years ago | from the no-sir-I-was-in-seattle-at-the-time dept.

Security 354

An anonymous reader writes "Nate Lawson, a researcher at RootLabs, has found a way to clone the wireless transponders used by the Bay Area FasTrak road toll system. This means you can copy the ID of another driver onto your own device and, as a result, travel for free while others foot the bill. Lawson also raises the interesting point of using the FasTrak system to create false alibis, by overwriting one's own ID onto another driver's device before committing a crime. Luckily, Lawson wasn't sued before he could reveal his research, unlike those pesky MIT students."

And they can record license plates. I think this hack has little criminal viability. Anyone who used it extensively would be caught in short order. Though authorities might be willing to let the criminal conduct continue on until the criminal passed the felony threshold.

Re:Cameras at every toll booth (1, Informative)

In toronto we have an electronic toll as well. Cameras and such and completely unmanned.

We have a law against dirty license plates. You may save on cash from using the highway, but some police officer will eventually hit you with a ticket (they do stop people with dirty plates) and your insurance rates will go up.

Tolled roads are very abnormal in Canada, but this one works reasonably well.

I consider using the state-provided roads as a privilege, not a right, that requires your car to be identifiable by a valid licence plate.
If the plates are obscured, either by dirt or by purpose, isn't it reasonable to give a ticket to deter this?

"We have a law against dirty license plates. "

Well, just rig up some sort of James Bond plate changing mechanism....where you can flip the plate, or just obscure it when going through the booth, then hit the switch, and set it to normal again.

I've been thinking of something like this for the stupid red light cameras they've been putting in down here in NOLA.

Back on the ez-pass system. For awhile I was having to cross the bridge across lake pontchartrain, and it was a toll bridge. I just don't like the idea of having a system track my movements, so I just paid cash...no toll tag for me. Sure, it costs a dollar more, but, worth it to me.

mshannon78660 (1030880) | about 6 years ago | (#24751725)

Down here (central Texas, Austin area), they have something called 'video tolling'. Essentially, anyone can go through the TxTag lanes, whether they have a transponder or not. If you have a transponder, you get a discount (I think it's 20%) off the cash rate; if you don't, you pay a premium (again, something like 20-33%) on the toll, plus a handling fee (something like $1 per bill). So yes, they can, in a completely automated fashion, take a picture of your license plate and record in a database exactly when you went through that toll plaza. If you drive on the toll road, you should not expect that anything will restore your anonymity.

Maybe if you stopped running red lights you wouldn't have a problem with the red light cameras taking your picture?

I mean, come on - I am against taking pictures of everything all the time, but the red light cameras are one where they are pretty foolproof at only taking pictures of scofflaws who are endangering everyone else. That seems to be a good thing.

Your kidding right? There have been many cases of the Red Light Companies moving sensors around to catch people who Hadn't run the red light. And the one time I got a ticket from this system, the plate was unreadable, the Dark 4 door sedan pictured didn't look anything like my white 2 seat convertible, and we (my car and I) were 800 miles away at the time on the time stamp.

Just gotta love that. In addition, I've also heard of an automated speed camera sending a fine notice to a farmer for his antique tractor with a max speed of 8 kph - it said he was doing something in the high 80's with it.

The funny one I saw recently sent a ticket to a guy - the picture showed the car was in the process of being towed.

Of course, they're also throwing the ball back at you - you have to prove you're innocent, not the other way around.

Back on the wireless toll roads, my first thought was that 'they even encrypt garage door openers to prevent this today!'. For anything more serious than a simple inventory, encrypted RFID devices should be the rule.

"I mean, come on - I am against taking pictures of everything all the time, but the red light cameras are one where they are pretty foolproof at only taking pictures of scofflaws who are endangering everyone else. That seems to be a good thing."

As the other poster said, there have been cases where the private company running these cameras weren't making enough money, and shortened the yellow light, or even rigged the cameras to take pics while light was yellow, but, showing red on the ticket. Studies have shown that in a VERY high percentage of cases, if they extended the length of the yellow light at troublesome intersections, that the number of people running red lights almost dropped to near zero.

One of my other problems with the system here...was that the cameras aren't only taking pictures of light runners. They have still and full motion cameras...they showed a case of cars sitting there at a red, and a car going around the front one and running the light, all in full motion. That means the cameras are running all the time...I don't like that.

I'd heard that someone was bringing suit against them in that they are unconstitutional in the state of LA...in that they aren't on every intersection, and the law states something like there has to be equal enforcement on all LA roads,etc.

popeye44 (929152) | about 6 years ago | (#24751555)

We had 2 intersections here in Fresno that had Red Light Cameras. The company that put them in had a hell of a marketing department and sold the city on the idea. FF 2 years and Fresno made them pull the cameras and take down the poles etc. The company lied about how much money it would bring in. People in Fresno knew the lights would catch them and basically stopped running it. You can't make money if no one breaks the law. Better a few jump through a yellowed/red and get caught by regular police than no one ever doing it.

Yep - that was my first thoughts too. Driving with an unreadable license plate, though, is grounds to get you pulled over anyway.

In case you didn't know, most toll booth places have:

    Cameras front-mounted to take a picture of YOU or passengers...

    Cameras in the back to take a picture of your plate...

    Occasional cops sitting at the side of the road that are ready to pull you over.

It's academically interesting (and it should be) but not useful for the criminal. You can always simply drive through a checkpoint without an ez-pass, and most likely nothing will happen [nbc4.com] for a long time. Is it worth it? Nope.

"The system is about to take a sweeping technological turn, doing away with booths, baskets, cash and relying on video cameras to bill drivers."

How exactly do they plan to do that? Not everyone passing through their state lives there, or near enough to realistically expect them to sign up for EZ-Pass. Personally, I don't have it because, while I live in a state that does use EZ-Pass, I only go through the tolls perhaps twice a year.

Clearly, the states would much rather switch to all electronic tolls (they seem to make a game of making the cash-accepting lanes as difficult to find as possible), but to do away with cash altogether? Not possible.

The only toll roads in the whole state are north of I-80. Of course, you guys up there think Illinois' southern border is I-80 anyway.

Uncyclopedia has a good article about our great state. [uncyclopedia.org]

Illinois boasts hundreds of thousands of miles of roadway, almost 1.7% of which are in drivable condition at any given time. The rest are under construction, fuelling the state's economy by adding needed jobs in the road construction industry, and the Illinois Political Patronage Brotherhood of Sign Holders and Shovel Leaners, which depends on constant road construction for its continued existence. To maintain the roads in this condition, state law requires concrete to contain at least 35% white corn meal (cleverly subsidizing the Illinois farmer as well as the road construction industry). It also mandates tar products to be replaced with black licorice in the manufacture of asphalt. During summer months, hapless Illinois home-owners across the state obtain big brushes and squeegees, and can be seen coating their driveways with a new layer of melted black licorice, vainly but valiantly attempting to prevent them (the driveways, not the home-owners) from disintegrating into grey pebbles. This explains the popular saying: "There are two seasons: Blizzard, and Tornado". Also synonymous with "Winter and Construction" in the North.

Re:Cameras at every toll booth (1)

erroneus (253617) | about 6 years ago | (#24751747)

That wouldn't work for long. MOST people generally drive the same areas on a routine basis. And even those people that don't could be flagged for chase. Essentially, once someone has been identified as using a false or copied code, they can take pictures of the vehicle and post it for chase along with the code being used. There are a variety of ways an individual can be flagged and the only way to continue doing it is to change vehicles and codes frequently and that would become a burdensome crime to maintain.

The false alibi thing could conceivably work if you had proper cooperation. All one would need is to hire someone to drive your car while you drive theirs, but then again, under such a scenario, cloning transponder codes wouldn't even be necessary... just pass the person your car, your cell phone and credit card to make a gasoline purchase or two and you've got a pretty convincing alibi.

You've got it the wrong way around - people won't use this to create alibis before committing a crime, they'll use it to establish evidence of the target being in a certain area at a certain time even though he swears he was elsewhere

At any rate, certain requirements have to be met before something can be introduced as evidence. I'm assuming most things (like this) would, by default, not constitute evidence anyway. Email (at least in this country) needs to be provided along with an audit trail before it's accepted as evidence

Re:Alibis? (1)

Re:Alibis? (2, Interesting)

Farmer Pete (1350093) | about 6 years ago | (#24751125)

This wont help with Alibis because no court will accept a time stamp and a transponder id as evidence. Who is to say that you were driving the car, or even that someone didn't take your FastPass and drive through with a different car. To be entered into evidence you would have to take the time/id and review the video records to get a car/face match.

Even if this worked for an alabi like TFA implied, you could get into trouble real quick if you didn't know the final destination of the car. What? You tell the police you went to X? Well the car you gave your ID went to Y. The car also is still driving around town and went through two toll booths while you were in police custody.

Between the splash screen redirects and the ads, this article is nearly unreadable. Here's the text for those who don't want to put up with the crap.

----
Drivers using the automated FasTrak toll system on roads and bridges in California's Bay Area could be vulnerable to fraud, according to a computer security firm in Oakland, CA.

Despite previous reassurances about the security of the system, Nate Lawson of Root Labs claims that the unique identity numbers used to identify the FasTrak wireless transponders carried in cars can be copied or overwritten with relative ease.

This means that fraudsters could clone transponders, says Lawson, by copying the ID of another driver onto their device. As a result, they could travel for free while others unwittingly foot the bill. "It's trivial to clone a device," Lawson says. "In fact, I have several clones with my own ID already."

Lawson says that this also raises the possibility of using the FasTrak system to create false alibis, by overwriting one's own ID onto another driver's device before committing a crime. The toll system's logs would appear to show the perpetrator driving at another location when the crime was being committed, he says.

So far, the security flaws have only been verified in the FasTrak system, but other toll systems, like E-Z Pass and I-Pass, need to be looked at too, argues Lawson. "Every modern system requires a public security review to be sure there aren't different but related problems," he says. Indeed, in recent weeks, researchers announced flaws in another wireless identification system: the Mifare Classic chip, which is used by commuters on transport systems in many cities, including Boston and London. However, last week, the Massachusetts Bay Transportation Authority (MBTA) filed a lawsuit to prevent students at MIT from presenting an analysis of Boston's subway system.

The Bay Area Metropolitan Transport Commission (MTC), which oversees the FasTrak toll system, maintains that it is secure but says it is looking into Lawson's claims. "MTC is in contact with vendors who manufacture FasTrak lane equipment and devices to identify potential risks and corrective actions," says MTC spokesman Randy Rentschler. "We are also improving system monitoring in order to detect potentially fraudulent activity."

In the past, authorities have insisted that the FasTrak system uses encryption to secure data and that no personal details are stored on the device--just two unique, randomly assigned ID numbers. One of these is used to register the device when a customer purchases it, while the other acts as a unique identifier to let radio receivers at tolls detect cars as they pass by.

But when Lawson opened up a transponder, he found that there was no security protecting these IDs. The device uses two antennas, one to detect a request signal from the toll reader and another to transmit its ID so that it can be read, he says.

By copying the IDs of the readers, it was possible to activate the transponder to transmit its ID. This trick doesn't have to be carried out on the highway, Lawson notes, but could be achieved by walking through a parking lot and discreetly interrogating transponders.

What's more, despite previous claims that the devices are read only, Lawson found that IDs are actually stored on rewritable flash memory. "FasTrak is probably not aware of this, which is why I tried to get in touch with them," he says. It is possible to send messages to the device to overwrite someone's ID, either wiping it or replacing it with another ID, says Lawson.

"Access to a tag number does not provide the ability to access any other information," says MTC's Rentschler. "We also believe that significant effort would need to be invested in cloning tags." He adds, "If any fraudulent toll activity is detected on a customer's account, the existing toll-enforcement system can be used to identify and track down the perpetrator."

Lawson says that using each stolen ID just once would make it difficult to track down a fraudster. A better solution, he believes, would be to require toll readers and transponders to carry out some form of secure authentication. But this would require changes by MTC. As an alternative, Lawson is working on a privacy kit to let drivers turn their transponders on and off so that they are only vulnerable for a brief period as they pass a toll.

There is another way, he says. "It's probably in the user's best interest to just leave it at home." This is because FasTrak uses license-plate recognition as a backup.

Ross Anderson, a professor of security engineering at Cambridge University, in the U.K., says that "very many embedded systems are totally open to tampering by anyone who can be bothered to spend some time studying them."

Competent use of encryption is the exception rather than the norm, Anderson adds, and the situation is unlikely to change soon. "One industry after another is embracing digital technology, and none of them realize that they need computer security expertise until it's too late and they get attacked," he says.

Bruce Schneier, chief security technology officer at BT, based in Mountain View, CA, says that it is too easy for companies to get away with lousy computer security. "Honestly, the best way is for the transportation companies to sue the manufacturers," he says. "Then they'll think twice about selling shoddy products in the future."

It is worth noting that the FasTrak system is deployed throughout California and not just in the Bay Area. I have four tollways near my home alone that use the system and I live in Southern California. It is a given that if it is a Toll Road and it is in California that it uses FasTrak. The only exception may be toll bridges.

I wonder if Nate Lawson had read Cory Doctorow's "Little Brother" before his work on the Fastrak transponders?

It just so happens that Doctorow's fictional 'Little Brother' [craphound.com] work describes just such an exploit being used on a Bay Area transit card system.

Having said that, Doctorow mentions in his preface that most of the technologies in the work are either current reality or the possibilities of the near future.

Nowadays, it seems it's more about which transit card/xpndr system hasn't been done yet.

I don't have the newspaper article on hand, but a couple years ago in Toronto, someone was avoiding tolls on the 407 (Ontario's only toll road). They put their license plate on hinges, and attached a piece of string to it that ran through the car to the front. A tug on the string, and the plate flipped up.

And he would have got away with it if it wasn't for those meddling-- well, Ontario Provincial Police doing a blitz on the highway specifically looking for speeders, dangerous drivers and toll-evaders.

Where I live, it's common for thieves to steal license plates and slap them on their car before committing a crime. It raises far less attention than a car with no plates, and even if bystanders copy down the offending plate number, such information is useless.

Combine a stolen plate with a stolen ID, and it would be very difficult to track down a one-time offender disregarding something like facial recognition (drive through the tollbooth every day at 8 AM, though, and I'm sure they'd catch on pretty quickly).

Another loophole is those temporary 30 day tags you get when you purchase a new car. In many states they are not unique, not trackable (in our state they just have a sharpied 6-digit expiration date in big numbers), easy to fake, and nobody thinks twice about them.

Any obvious physical means to obscure the license plate would be self-defeating.

Just get some polarizing film and put it over your license plate. Unless the cameras are head-on (which generally they're not) they're going to get a black rectangle where the license plate should be.

A 'clear' film would be much less likely to attract law enforcement attention than some kind of physical change.

I believe this kind of thing is illegal but then again if you're going to be using a cloned transmitter I don't see that breaking another law would cause you to lose any sleep.

colorado replacing toll booths with cameras (1)

peter303 (12292) | about 6 years ago | (#24751339)

About 10% of the toll road rides are infrequent-users who dont have transponders. Colorado decided to terminate the booths and use cameras to mail bills to users. Its cheaper than people.

What about the license plate? (0)

Anonymous Coward | about 6 years ago | (#24750863)

In Massachusetts, the similar "Fast Lane" RFID transponder id is linked to your license plate. If you drive through a toll gate with an id that does not match your license plate (high speed cameras read the plate and use OCR to record it), your account gets flagged and you get a nastygram in your snail mail box along with a fine.

People victims to this type of clone would then obviously appeal and the stored license plate number of the cloner would then be easily used to find them.

This is nothing new... (2, Insightful)

Chineseyes (691744) | about 6 years ago | (#24750865)

When I was a teenager (late 90s) there were a few people selling a device about the size of two bricks that could fool ez-pass [ezpass.com] by using another person's id. This is why when you sign up for ez-pass you have to give them the make and model of your car as well as your license plate number. They have two cameras on either side of your car pointing at you and numerous overhead cameras when you pass through so I believe any sort of fraud would be pretty difficult to pull off. I'm sure California has a similar setup and if they don't then they better get working on it.

Embedded devices are rarely designed to be very secure. One of the problems is that often there is not enough space for strong crypto, even a strong cryptographic hash. Things are getting better these days, with smaller transistors and lower power circuitry, but it is still difficult to get really strong crypto in a small RFID transponder like that.

OmniGeek (72743) | about 6 years ago | (#24751723)

While it's true that passive RFID devices are notably short on power and computing capacity (and can be vulnerable to tricks like power-consumption analysis and direct physical probing to attack their encryption), the central reason most of these systems are poorly encrypted if at all is...

Cheapness, intellectual laziness, and garden-variety stupidity.

One CAN make these systems much more secure, but it requires cryptographic competence and the determination to do the job right. As Schneier says, crypto is hard to do properly, so it costs time, money, and thought. And the end user can rarely distinguish a secure system from a crappy one, so the economic incentive do do it right is minimal.

Methinks we could use a good set of standards and an accepted certification process for rating the attack-resistance of systems like this. Won't happen, of course...

No Authentication = Easy Crime (3, Interesting)

binaryspiral (784263) | about 6 years ago | (#24750907)

When you have the ability to send the same data over and over again without any form of authentication or obfuscation - yes, it can be copied and used by anyone else.

There are ways to prevent this:

Use a rolling code, like my garage door, key fob, and online banking fob uses.

Use another form of authentication, like color of vehicle, plate number, or something else easily identifiable on the car.

These are about as secure as my Speedpass fob that I can use to purchase fuel and snacks at Mobil stations. If its stolen, anyone can use it.

Re:No Authentication = Easy Crime (1)

Volante3192 (953645) | about 6 years ago | (#24751141)

There are cameras at CA FasTrak lanes that do take photos of the cars and your make/model/color and licence plate are on file.

I think it's reasonable to assume that for the wireless bit, they wanted it as simple as possible. Less data to send, less chance you'll miss anything at 80mph.

That's why the other bits are in place.

The insufferable thing is... they already HAVE cameras with character recognition at the tolls gates. If you blow through the lane without paying the toll, fast-track or otherwise, the system snaps a photo of your license plate and you get a ticket for the violation in the mail a few days later. So if they were to just change their software, they could dispense with the expense and hassle of fast-track and the toll lanes, and just photo the license plates that use the bridges and bill you at the end of the month for that usage.

But that would mean giving up the ticket income for toll violations, the toll collectors are no doubt unionized, and someone is getting kickbacks on fast-track. Gotta love the government, eh?

Billing is an issue, though. You have to be in some kind of electronic payment system for that to work. If they have to spend $.42 to send you a $2 bill, they're not saving much over the fancy system.

But you're still right, though. Why not just register your tag with an electronic billing firm, that has permission to deduct the tolls from an account you fill for the purpose?

Unfortunately, pretending to be someone else may save you some tolls, but eventually someone will figure out who is posing as a different driver. The Bay Area bridge, airport parking lots, and many other places have cameras that photograph both the driver and the license plate of the vehicles that pass. Maybe some good will come out of all this surveillance.....but probably not.

Old wireless toll systems didn't event use encryption, such as the case of old Amtech 2.4GHz systems, which are limited to store information similar to a typical ISO Track #2 credit card (PAN [wikipedia.org] , and some other info). However, modern system, such as the CESARE [its-sweden.se] european standard (public information, no revealing secrets here, of course), includes modern security (realtime generated derivate key negotiation, etc.).

Not yet. But he will be. We are seeing an irresistable force meeting an immovable obstacle. Society is creating a scenario where as technology moves forward the gap between truth, progress, science - and security, stability, state widens. They are not naturally in conflict, but we have chosen to make them so. The law and research are increasingly at odds. Corporations and governments have begun to build presumed ignorance into business and administration models, backing up security through obscurity with sanctions of threats, imprisonment and violence. The way it looks to me over the next 10 years research is not going stop, and neither is the landgrab for power and easy exloitation. Sooner or later these worlds are going to clash in a big way (many would say they already have as the economy collapses). Basic activities like the teaching and practice of chemistry, physics and computer science are being attacked to maintain a fragile status quo. Yet, economic development is not possible without research and education. It seems society has painted itself into a corner. It cannot progress without science and yet it is so threatened it will not tolerate it amongst its people. It's killing off the nutrients that feed it.

The solution to all of the comments that your license plate will still identify you: as you drive around simply start saving and replacing the ID in devices as you pass other drivers. After a week you could replace your own ID with any of the values you swapped around during the week (hundreds? thousands?). Voila! Plausible deniability.

I'd hate to be working for whoever has to sort out the mess in the end, though. That's a lot of work to create for others just to avoid some tolls.

...given that almost all of the toll transponder systems in the US have cameras, and plate recognition is done. I once got a ticket from another state (NY), claiming a plate I had years ago had gone through one of their upstate tollbooths. Also, my father would get notices in the mail from our state's system when he moved the transponder to a vehicle that wasn't registered to use it. So.

You're right, it's done that way because the transponder is "the contract", similar to a credit card. Using just the vehicle identification plate, you should have a contract for every car you drive, while with the transponder you're able to use your own/lover^Wwife/renting car, etc.

The idea of hacking the FasTrak system (or, more specifically, cloning FasTrak units) for false alibis and other social mayhem was explicitly brought up in Cory Doctorow's Little Brother [craphound.com] .

1. How many tolls will be stolen? Too few for anyone in the project to care. They will treat this like "ID theft" and the burden is on you.

2. How many people are going to want or actually *do* anything TFA suggests. It's a number very close to zero.

The same kind of thinking applies to most automated transit toll collecting system. No one that could do anything about these issues cares or would be foolish enough to waste budget on corner cases like this. It would be a huge political/professional liability if they did.

E-Z Pass (1)

akunkel (74144) | about 6 years ago | (#24751589)

I don't know about cloning an E-Z Pass but if you use the E-Z Pass tag on a car that it is not registered to you, you get a ticket from them with the offending license plate number. At least this is the case in the NY Metro area. My wife got a ticket when I used her pass while waiting for a replacement for my non-functioning pass. I have had several friends who used to swap the passes between cars start to get tickets for the same reason. Are they scanning all of the license plates and matching them with the E-Z Pass tag or only some? This would seem to make cloning less effective unless you were maybe driving a stolen car/swapped plates since they would know the plate number of the cloned tag.

We mustn't assume that these vehicle transponder only use is for for toll collection. They work anywhere they want to place a Transponder reporting unit.and they they can even read transponder from other states
I don't know about California,
  but many other states use similar transponder units in vehicles. In our state there are readers all over the place. they are used for example to track vehicle movements, this information is used here in the North east to track unsuspecting Criminal suspects and to enforce traffic camera violations , some police vehicle have a reader in them to track suspects on the move .
And since there is a time stamp and unique serial number, they can be used by the police to get you a speeding ticket.
  Example a reader sees you moved from point A - B too quickly and Bingo ! your average speed over that distance is know They can be used for many purposes beyond toll collection

  Hacked transponder units may throw a monkey wrench into potential criminal investigations , traffic violation support and vehicle road use tracking statistics , and many things not know to the public , for example If I wanted to clobber only out of state drivers or those who can better pay fines, the police can just read these things and statistically more out of state drivers or those who travel and use hem have more money. What better way to target them for traffic violations and increasing revenue
In our state You must have good credit to get one of these things , so they know you can pay their big fines , and this is just but one nefarious use by crooked lawmakers
