'Stingray' Phone Tracker Fuels Constitutional Clash
WSJ ^ | 22 Sept 2011 | JENNIFER VALENTINO-DEVRIES

Posted on 09/22/2011 8:21:28 AM PDT by Palter

For more than a year, federal authorities pursued a man they called simply "the Hacker." Only after using a little known cellphone-tracking device—a stingray—were they able to zero in on a California home and make the arrest.

Stingrays are designed to locate a mobile phone even when it's not being used to make a call. The Federal Bureau of Investigation considers the devices to be so critical that it has a policy of deleting the data gathered in their use, mainly to keep suspects in the dark about their capabilities, an FBI official told The Wall Street Journal in response to inquiries.

A stingray's role in nabbing the alleged "Hacker"—Daniel David Rigmaiden—is shaping up as a possible test of the legal standards for using these devices in investigations. The FBI says it obtains appropriate court approval to use the device.

Stingrays are one of several new technologies used by law enforcement to track people's locations, often without a search warrant. These techniques are driving a constitutional debate about whether the Fourth Amendment, which prohibits unreasonable searches and seizures, but which was written before the digital age, is keeping pace with the times.

On Nov. 8, the Supreme Court will hear arguments over whether or not police need a warrant before secretly installing a GPS device on a suspect's car and tracking him for an extended period. In both the Senate and House, new bills would require a warrant before tracking a cellphone's location.

And on Thursday in U.S. District Court of Arizona, Judge David G. Campbell is set to hear a request by Mr. Rigmaiden, who is facing fraud charges, to have information about the government's secret techniques disclosed to him so he can use it in his defense.

If you knew where the suspect was ... you would just arrest him, you wouldn’t bother to try to find him with his cell phone.

That makes utterly no sense.

All you need to do is locate the suspect, beam a beam near him, power up his phone, use the Stingray software, and BOOM now you know where the suspect is!

See what I mean?

It may work like this:

Get general area (cell site, sector) from the cellular operator.

Then use this device which will decode the equipment serial number from the transmission that a cellphone periodically sends to the network. With the area narrowed down, you can use Angle-of-Arrival methods to triangulate on the specific ESN broadcast as you drive down streets in the general area. House located, no GPS needed.

THey’ve been doing this for years. First time I heard it called stingray, but that’s the only news here.

If this someone “Hacker” was getting into government or business files to access private or sensitive material in a felonious manner, I have no problem with the FBI getting their criminal this way.
Better than letting them continue to destabilize the property of others IMO.

Turning it off will work as well as taking out the battery (ignoring the risk you might turn it on by accident if the battery is still in it).

The Stingray works by getting the phone to report in to what it thinks is a cell tower. That's what phones do when they are on but in standby mode, but not when they are off. That's why you can walk off a plane in a strange city and suddenly receive a call. When you turned your phone on, it checked into the nearest tower, updating the carrier's database to show your phone now in the new city.

BTW, that standby activity is also why battery life depends on how far you are from the nearest tower. If you are far from a tower, the phone needs to transmit at higher power in order to check in, draining the battery more quickly. My phone's battery will last a week in standby if I can see a tower out the window, but only a day or two if I'm in a fringe or no-service area.

While that is wise, I would have preferred it if you had peed yourself, too. :)

That’s similar to how we detected submarines with a passive tail. if you know your speed and direction and get 1-2 detections you can estimate location very quickly through triangulation. A bit more difficult if the other target is moving, but a few more pings and you can estimate that as well. If all they are doing is listening for the ping then I would say this is public access information the phone is transmitting similar to talking in public. The part they would need to get a court order for would be the specific signal/transmission associated with that phone ID - similar to a wiretap.

Doubt it. You might be able to inject some energy into the phone's circuitry, but not in a manner that would cause its operating system to boot up and squawk. If you were close enough to do that, it's much more likely you'd simply destroy the phone, like an EMP or such.

There is a gadget known as the nonlinear junction detector. It is capable of detecting the presence of electronic devices nearby. It works by flooding the area with RF. It listens on harmonics of its transmit frequency. If there are nonlinear junctions nearby (semiconductor devices), they will receive the detector's energy and re-radiate some of it at multiples of the original frequency, thus betraying their presence.

Nonlinear junction detection is the basis of those bug sweepers you see used in movies. You basically explore the premises with the sweeper and investigate any nonlinear junctions found. The range is short, however. You have to be on top of a bug to find it.

When the US built a new embassy building in Moscow back in the seventies or eighties, the Soviets got to the concrete supplier and added thousands of little semiconductor diodes to the concrete mix. The result being that bug sweepers were useless in the new building, bugs being found everywhere!

If it really matters to you ... I would do some serious research into this statement.

What govt. can do to him they can & will do to you . The FBI is not an organization of angels but of police with a attitude that they ARE the law not servants of the law.

Left unchecked this attitude leads to a police state in the name of protecting you from your self.

Whatever. They bagged a hacker. That’s all I care about. I don’t really give a crap if the government knows where my cell phone is located.

wait till they start using your phone to mail you tickets for speeding, bills for miles traveled....

First they came for the smokers.. but I don’t smoke...

Do you see a possible flaw in that argument? My cell phone doesn’t drive so it can’t get a speeding ticket. Anyway, why do they need my cell phone to do that? If they are that powerful, they can bill me anything they like and I have to pay it. see the IRS.

No I do not. Your cell phone travels with you does it not? GPS shows you traveling down the interstate. In a 60 MPH speed zone. but your going 90 MPH. Ticket is generated and mailed.

Much like the red light cameras.
