Who's Spying on Your Cell Phone?

Posted September 10, 2014 12:00 AM by HUSH
Pathfinder Tags: cell phone spying surveillance

Growing up, I saw always a fan of Spy vs. Spy (that according to my research is still appearing in MAD Magazine to this day). For those unfamiliar, it was a Wild E. Coyote vs. Roadrunner-style comic about two international spies constantly trying to kill one another. One would spy on the other, try to exploit his opponent's vulnerability, but ultimately he would meet his untimely doom. This occurred week after week, all in just a few black-and-white panels.

Yet real espionage doesn't work that way. If someone finds a vulnerability, they're going to exploit it viciously and mercilessly (right, Jennifer Lawrence?). It's these type of people and events that make me reconsider my own electronics security, as well as a phone from ESD America.

ESD America is a value-added reseller of Android phones. The company employs a team of software engineers to make cell phones more secure and it claims to have patched nearly 500 security vulnerabilities in the Android OS found on the Samsung Galaxy III. Beforehand, the phone was susceptible to 90 unregulated data transmissions per hour-not leaks necessarily, just instances where the phone transmitted data to an unknown recipient.

Attacking low security cell phones is becoming more and more common. First, there is the problem of fake phone cell towers, a.k.a. "interceptors." These towers are perceived by phones as a typical antenna, but they are radio-equipped computers that use obscure commands to communicate with a phone's secondary operating system that is inherent on the device and relays info between the main OS and the cell tower. While this equipment isn't cheap (starts at $3,000), its attacks are unperceivable. Simply entering the interceptor's range is enough to render your private data publically available.

ESD creates a monthly interceptor map to illustrate known locations. Interceptors are commonly found nearly military bases, implying government administration. They are also used by organized crime syndicates to steal secrets or personal information. They can eavesdrop, intercept calls and texts and even take 'spiritual' possession of the device. Last month, the FCC announced they had begun investigating the use of interceptors.

There is also the StingRay phone tracker, which in many ways acts like an interceptor. But while interceptors are primarily used by upper-echelon government agencies and criminals, StingRays are used by local and regional police departments. Often, these devices are vehicle or hand mounted, meaning that mobile interception has been brought purposefully to your doorstep. Some American agencies have admitted to regularly using StingRays without obtaining a warrant and this practice, at least initially, has been protected by anti-terror laws.

Basically, the gist of it is this: once you elect to electronically record and store data, you need to assume its public property. It is an unfortunate consequence of an era that has essentially shaped up to be the Wild West of Information Technology: a no-holds-barred free-for-all on both sides of the law.

While someone like me probably doesn't need the $3,500 ESD America encrypted smartphone, it's easy to envision a huge market for true cellular protection. I'm sure if more cell carriers were able to offer better protected phones at a higher price, at least half of their customers would consider buying them.

Well funded criminals and terrorists will buy the encrypted phones, and the government will spend billions collecting and storing conversations about what the Kardashians are wearing, or endless garbage about a football player punching his girlfriend.

I am not clear on whether the "Stinkray" or other device is perceived by the cell phone to be a cell tower or if a cell tower also perceives it as another cell tower.

Could multi antenna arrays on a cell phone recognize that the perceived cell tower is not at an established position or distance?

Cellphone towers do not communicate to each other in that way.

Think of a cellphone coverage area as a hexagon 'grid' laid over a region(1). Each 'hex' has three cell towers around it, on three corners of the hex, with an empty 'corner' between any two towers. All three towers are monitoring cellphone traffic in that hex, and pass 'control' (primary link status) to the tower with the strongest reception for any particular phone, and that tower then 'handles' the phone, sending signals to cut phone signal strength to 'nominal' for the situation(2), etc. Each tower is also looking at the other two cells that share the 'corner' the tower sits on. Towers work on one of three frequency ranges, so every hex has an A tower, a B tower, and a C tower. The communication between towers is simply to 'hand off' phones from one tower to another as the phone moves from the 'A-strong' section of the cell to the C-strong section. The effective radio range of a tower is something like 75% of the distance to the next tower, so that there is complete coverage, but each frequency band has a geographic 'quiet zone' between towers that use that band. The towers talk to each other through the phone, having the phone report the signal strength on all bands it receives, then the tower reported as best continues as the 'primary' for the phone until the signal is reported as better for another tower.

I'm guessing that a 'Stingray' system monitors all three bands, and then 'spoofs' the weakest tower, becoming the strongest tower in the area, then once it takes control, it tells the phone to cut broadcast power to zero on the other bands, making the phone 'vanish' from the 'real' network. It basically becomes a 'microcell(3),' handling all legitimate traffic in the local area, and passing the data on to the normal cellphone grid, but keeping a copy for itself.

Notes)

1) Radio coverage is actualy round, not hexagonal, but for cellphone grids, it's easiest to visualize in hexes, the official maps used my the Engineers to show coverage and to lay out new tower locations use the hex-based system.

2) If you consider Cellphone strength to be a scale of 0-10, with zero being 'off' and 10 being 'full power,' most towers will adjust the power level of the phones in their control to a perceived strength of 3-5. Considering signal loss over distance, that means that phones at the edge will be broadcasting at a local 7-8, while closer phones with clear line-or-sight to the antenna bay be broadcasting at a local 1-2. (The nominal strength assumes typical interference and reflections, so a 'direct link' ends up with a stronger signal than expected for the distance. A phone right in front of the antenna bay be broadcasting at a local power of 0.01, since no phone was expected to be that close.)

3) The way 'microcells' would typically be set up would be to draw straight lines through the cell to be divided, from Tower A to Tower B, from B to C, and from C to A. Then the midpoints of those lines would be determined, and halfway between A and B would be erected Tower c`, between B and C would go a`, and between A and C would be b`. There wo7uld be little if any reprogramming of the network, as the new towers would generally have the best signal strength within the cell, the three 'small primes' would basically take over the entire cell except for the edges. This would also lessen the traffic on the original towers as they only have to watch two cells each instead of three.

If by means of "marking" signal strength or direction, for any known legitimate tower, could this data be used to flag any source not located in a marked location?

Please disregard my stupid questions.

I just have one more...

If I look real close at the lens on my cellphone camera, I can see a little eye looking at me. What does it mean?

The graphics are nice, but there seems to be a dearth of actual photos or real documentation for any of this information. I would love to see some actual documentation.

Mostly it looks like an ad for encrypted cell phones...quite pricey ones at that.

It sounds like one of those Popular Science articles that is more Pop than Science.

True, there are Washington Post articles and FCC this and thats, but the FCC link on the Post's page is dead as is the StingRay link in HUSH's post is dead.

edit: got it to work...working on it.

I see a pointer in a major urban area near me. I can easily take a pic and research the license for the installation and post it up. It seems like someone would have done this already. Google has failed me there.

Anyone else?

So...if the supposed good guys, let's say the FBI, is using an IMSI to monitor someone without a warrant, and a private citizen (not necessarily the guy the FBI is listening to) uses an IMSI catcher (monitoring the monitor) and then reveals that the FBI is doing so...

...isn't that really the same thing as the FBI doing the monitoring? The IMSI catcher is monitoring the FBI's communications and using it to reveal the FBI's intentions, whether or not the "good citizen" knows if the FBI has legal standing to do so (a warrant). It is almost impossible to know if the FBI did unless you had an inside man to tell you to begin with (which is also illegal).

Who's to say whether those who are monitoring those whom should not be monitoring (supposedly) is doing the right thing when the thing they are doing is illegal (monitoring and revealing police communications/actions during an "investigation")?

bad guys --> cops --> internal affairs --> FBI --> citizen --> bad guy --> lather, rinse, repeat

Where does the monitoring end?

I suspect that since the constitution appears to be dead, FBI and local law enforcement is using the stingray to monitor all calls in an area, and may even have software in place to recognize keywords...say, a drug deal going down.

If I were in law enforcement, there would be no mention of my Stingray in court since it would likely be tossed as a warrantless search. I would use my Stingray to peer into people's lives, then I would go find probable cause to go after them. My probable cause is easy, since it can be based on complete fabrications. I make my bust, send another person to prison for possession with intent to sell, and get another gold stripe on my arm. Rinse, repeat.

What's a Stingray?

PS- This neat equipment is being paid for with grants from Uncle Sam via the DHS by taxpayers.

Your thoughts probably aren't far from reality.

As far as what's a Stingray...

I found realatively believable looking pictures:

This looked pretty legit with the standard 19" rack mount assembly and all. But then I ran it through ELA and found that the entire thing was photoshopped. This editiing took a bit of time, so I have to commend the spoofer for that!

Here's the ELA:

AND...yikes,what a hatchet job!!!

What clued me in was the label in the top right...it looked out of place with the clipped corners and no placard holder, and the font was too large and not in perspective with the ~15 angle of the shot.

Just because the photo's might have been photoshopped, it that does not always necessarily mean that they are fake. Sometimes they are just cleaning them up to make them look more presentable. I can tell you, with certainty, that at least one of those is real.

Oh, I agree...

...but some of the added-in text and what-not is totally unnecessary. If you wanted the text to appear sharper than the original, yes, but a placard with the missing holder is just odd.

The "closer to original" one of the Stingray II is somewhat believable.

The marketing shot of the Gossamer is understandable.

It seems like there would be more pics of the gear available. The antenna ports look wrong for the spectrum of interest...

Interesting. This says that your second picture is the US patent picture, which is BS, because the USPTO doesn't like photos unless they are absolutely necessary.

Good ole wiki:

Hmm.......an NDA?

http://www.wired.com/2014/03/harris-stingray-nda/

What a neat way to frame and lock up enemies of the state.

I'm not sure why anyone would bother photoshopping images. What they look like doesn't really matter.

http://www.ronpaulforums.com/showthread.php?428664-Meet-the-machines-that-steal-your-phone%92s-data

I actually wouldn't have a huge problem with this if the data was screened and deleted immediately. Unfortunately, we've known forever that there are bad apples in law enforcent, and thanks to the IRS scandal, we now know that there's not a single faction of government that hasn't been tainted by the corruption of the Obama administration.

So we now have, hypotheticaly, cops (agents of Law) commiting Purgury (lying to a Court of Law) to avoid Fruit of the Poisonous Tree

Right now I am SO glad you are NOT in Law Enforcement.

That was a hypothetical. It's not something that I would personally do, but I'm sure that similar scenarios happen all the time.

I had a cop buddy that is now deceased, and when he was on patrol, he never went out without an unregistered "throw away" gun, just in case he shot somebody that was unarmed.

"he never went out without an unregistered 'throw away' gun, just in case he shot somebody that was unarmed."

That's just plain sick. Shooting an unarmed person is a risk cops take, but being prepared in advance to frame the victim just in case? Why be be a cop at all if you think you have to resort to measures like that?

It's not like someone put a gun to their head when they were choosing their career, making them be a cop. They chose that profession freely, willingly. So what kind of sicko chooses to be willing to shoot someone and then frame them, rather than, say, changing to a different profession if they thought it would come to that - a profession that does not demand you sell your integrity to the lowest bidder?

Re: Who's Spying on Your Cell Phone?

Could this be say a "Homeland/NSA/FBI" installed unit that when needed, can be used to follow suspects mobile phone wise?

Obviously if for example, terrorist activity is noted in an area, there must be some equipment, already installed, ready to be used when required to give indications of where a search might prove useful....

Suddenly installing stuff close to a terrorist hideout might be far too obvious!!!

NOT having equipment installed and ready might be taken as a negative to anyone seriously affected by said Terrorists.....

"You are screwed if you do and screwed if you don't" type of thing!!

The only thing against that is that the map does seem to indicate that only a small proportion of the US is covered.....or the map is seriously out of date.....maybe they hide them better, or leave them switched off till needed, less easy to detect!!
