Hacker Teaches iPhone Forensics To Police
Ponca City, We love you writes "The Mercury News reports that former hacker Jonathan Zdziarski has been tapped by law-enforcement agencies nationwide to teach them just how much information is stored in iPhones — and how to get it. 'These devices are people's companions today,' says Zdziarski. 'They're not mobile phones anymore. They organize people's lives. And if you're doing something criminal, something about it is probably going to go through that phone.' For example, every time an iPhone user closes out of the built-in mapping application, the phone snaps a screenshot and stores it. Savvy law-enforcement agents armed with search warrants can use those snapshots to see if a suspect is lying about whereabouts during a crime."
Haw. If you're gonna rob a bank or burglarize a home, why not do it in style?
Envision a crook trying to scream at the clerk to empty out the register while pausing to say, "Hold up, I gotta take this call..." Or instructing his getaway driver, "Turn left here....um, right here...oh, Mike just broke up with Jen...turn left here, exit 95..."
Compartmentalize, crooks. Compartmentalize.
You would think most criminals would know not to carry a cell phone at all, since the cell towers tracks and record their location at every moment.
"For example, every time an iPhone user closes out of the built-in mapping application, the phone snaps a screenshot and stores it." - TFS What?
I'm guessing it does that because when it opens it wants to look just as spiffy as it looked when the user closed it, and it can't do that if it has to re-render the map from scratch.
Most smart people find other work for two reasons:
1) When you are smart, you have options. Smart is a talent people want, particularly practical smarts of the problem solving nature. So you find that when you have that, you have options of where to work and what to do. Makes crime less attractive.
2) Smart people can better understand the consequences for crime, and the likelihood of getting caught especially on repeated attempts. So even if crime is tempting, they don't do it because they are smart enough to think ahead and realize it isn't worth the risk over all.
Most criminals are just not that bright. A friend of mine has worked with the public defender's office and the stories he has of the stupid criminals they try to defend and just amazing. They get caught and busted by their own stupidity more than anything else. They love to run their mouths to the police, they never plan their crimes, etc, etc. More or less the only time they were able to get someone off the hook was when the police made a mistake. Otherwise, the criminals sunk themselves.
This is just making it even easier than it already was.
If it was really necessary, it is possible to triangulate the location of your phone by determining which towers your phone was communicating with.
If your phone has a location feature, you'll notice that when you try to disable it you will be presented with the options "Location On" or "911 Only". There doesn't seem to be any way to completely disable this feature. At least this is the case on Motorola and Blackberry phones.
If you are concerned about someone being able to track your location via your cell phone, the safest way to ensure it won't happen is to pull the battery.

Nobody would ever be clever enough to generate false data.. for an iAlibi? ..or clever enough to hack into and plant incriminating evidence? (not that there's ever been a security breach!)
..don't panic
This is for the animation of screens opening and closing. This news is about two years old. It doesn't specifically call out the iPhone model so it may not apply to the newer ones with hardware encryption unless the book's been updated since 2008.
It is also illegal when your electronics spy on you. So in fact apple software breaks the law by taking a screen shot of the map application and storing it.
As far as I know, caching an image by the OS is not illegal in any jurisdiction. Taking an image and transmitting it to someone who is not the owner of the device, without their permission would be a problem in some jurisdictions. But then, that's not what anyone is claiming is happening.
"For example, every time an iPhone user closes out of the built-in mapping application, the phone snaps a screenshot and stores it." - TFS What?
It's called caching. When an iPhone application switches to another application it can quickly store an image of the app's current state. When the user switches back it displays that image while the real view is being built. That way the user gets an immediate view of the last state of the app rather than having to wait around for that state to be re-built.
Your desktop computer's web browser (and many other programs and devices) does the same thing, it stores data for quick access and responsiveness. You'd be surprised at just how many devices use this technique, the iPhone is far from the only device to cache data.
It's a smart technique but yeah, if you're committing crimes then too bad for you. I'd suggest that maybe you shouldn't be using ANY electronic device during a crime that you don't completely understand what data it sends and stores and how to deal with it before it becomes evidence.
Sapere aude!
Just WTF is a "former hacker"? That's like a "former scientist" or a "former student" or - - I suppose if you accept "hacking" to mean "criminal cretin living in his mother's basement breaks into email accounts and spreads bots around the internt" - then someone COULD be a "former hacker". A real hacker never stops hacking. It's more than a way of life - it's a way of thinking!

one thing i have noticed is that google maps stores the voice cache right at the top of the SD card in its own folder. so anyone with an SD card reader can plug in your phone and listen to the voice prompts for your route. i am sure that it using the same kind of caching for screens....but you dont need to be a "hacker" to find the voice prompts.
they say it is often more relevant then the comment above, all we know is its called the Sig!
I'm not a lawyer, but as far as I can tell, those laws apply to remote data gathering, not storage on your own computing device. Otherwise every program that caches something would be illegal.

Do ALL people who work on horse farms have an IQ higher than Einstein's? Or is it just most of them? Or is he just basically a freak case that proves nothing?
I guess you grandfather smoked 80 cigarettes a day since he was 12 and he got run over by a truck one day short of his 120th birthday while training for a marathon.
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
The people that were smashing car windows in our neighborhood were seen, and followed running back to their house in our neighborhood.
In my opinion learning to not hit your own neighborhood where you'll be recognized and followed on foot to our house is the first, basic thing to learn as a new criminal. Apparently that's too much for some people. Planning ahead so far as to coordinate your efforts with a throw-away phone is several steps down that list.
It doesn't hurt to be nice.
Your iPhone is clearly not your friend, and this isn't the only story about why today. It's the fink waiting to rat you out at the first opportunity. Go look up the new Safari html 5 database tracking that uniquely identifies you to advertisers. Until the phone comes with strong enough encryption to defeat this hacker in addition to remote wipe that truly wipes the phone, you shouldn't be sleeping too well at night, courtesy of Mr. Steve Jobs.
"It's the height of ridiculousness to say for those 9 lines you get hundreds of millions."
You're both right. It only keeps one image - it's called Default.png. Yet it's possible multiple versions could be retrieved if the file's data blocks on the flash disk have not yet been overwritten by another file.
Point is: iPhone is doing nothing nefarious, secretive or underhand, as some here would love to imagine. Yet forensics could discover more than a person might first imagine.
Crook: "Hold up, I gotta take this call..." *answers*... "Hello? I can't hear you you're breaking up. HELLO?"
Clerk: "You're not holding it right.. here let me show you"
After logging in slashdot still does not take you back to the page you were on. It's been that way for 20 years.

I wonder how many will soon be tracked via Flash-based cookies and deep stored history options.
The Safari database seems to be an open and safe way to track a user via a normal 'ad' after a site visit.
Stop giving state task forces and feds signals intelligence via a next generation of toys in your pocket.
Go simple and swap any used device out asap.
Try a collection of dumb devices with no networking or life long databases.
Recall the Malcolm X script... "Don't never write nothing down
Cause if they can't find no [iphone] they ain't got no proof..."
The serial numbers, hidden databases, location services ect, almost makes you think someone really put thought into tracking.
Any ex CIA director's investment banks seed money linked to funding this stuff?
Domestic spying is now "Benign Information Gathering"
It's not an early morning and a lack of coffee that's not allowing you to explain yourself. It's the fact that you are voicing your hatred rather than a rational viewpoint. There absolutely nothing related to a walled garden here. It's a cache, pure and simple, and it's documented. Even free software uses caches.
If he doesn't, then he deserves to get caught.
He deserves to get caught in any case, because he's a f*cking criminal.
I don't care if it's 90,000 hectares. That lake was not my doing.
