In a previous post http://www.mysecured.com/?p=202 I showed that your data is not wiped when you do a normal restore. So in this post I will show you some of the ways you can wipe your phone with some degree of certainty that the information on it is wiped.
If you want to wipe your iPhone before you sell it on eBay or give it back to Apple because the touch screen stopped working all of a sudden! Then here are the different ways you can wipe it:
- BigBoss Wipe App Method: http://sleepers.net/news/?p=174
This needs the iPhone to be jailbroken as well. It does a zero out wipe on the device, so it will require a restore afterwards.
The basic idea of all of the methods is to overwrite the data in the user area. Be it by overwriting it with music as in Mogull’s method or by using a wipe tool as with BigBoss or by overwriting it with zeros as in Jonathan’s method. I prefer the latter two methods as overwriting with music might leave some of the data intact (call me paranoid!). But on the other hand it could be the only option for people who do not want to jailbreak their iPhone or do not have the technical expertise to do so.
A detective from the Oregon State Police notified me this afternoon that an out-of-the-box refurbished iPhone he purchased contained recoverable personal data including email, personal photos, and even financial information which he was able to recover using my forensic toolkit.
So, if you have to return your iPhone to an Apple or AT&T store and they offer to replace it with a new one, make sure that you wipe your data properly first. A proper bit level wipe is needed here and NOT a system restore!

Who: Jonathan A. Zdziarski.
Details: While some of a suspect’s data can be viewed using the direct GUI interfaces in the iPhone’s software, much hidden and deleted data is available as well, which may provide for more thorough evidence gathering. Existing commercial forensic tools are sadly lacking their ability to perform deep raw disk level recovery, and so Jonathan will demonstrate how to install his custom forensics toolkit on any existing model iPhone and send a raw disk image to a desktop machine. He will also show you how to recover files specific to the iPhone including deleted keyboard caches, photos, web objects, and much more. Jonathan’s custom forensics toolkit and his accompanying forensic manual will be available free to forensic investigators in law enforcement.
I know that you’ll love this as a research tool. I love the visulization part and not so much the cover-flow type interface. It is still in beta, so I am expecting more GUI improvements
Here is a link to a Video demo shown on CNET News.com. It shows the potential of software-as-a-service (SaaS) applications like Basecamp or Salesforce.com on the iPhone. This could boost the sales of the iPhone and at the same time provide another dimention to information accessable to the iPhone mobile device.
As requested by Haitham. The Hard drive is not actually a hard drive. It is a Samsung 65 Nanometer NAND flash part number “K9HBG08U1M” the same one used earlier in the 8GB iPod Nano.
Paraben’s Device Seizure can get a variety of data depending on the operating system version as well as whether or not the phone has been unlocked (often called Jailbreaking). The following is a general guide to what data can be acquired from the different versions, however, our testing shows that different Jailbreaking methods unlock different portions of the phone (for instance, one method allowed Device Seizure to acquire most media files but did not allow access to phone records, contacts, or images uploaded to the phone):
Firmware 1.0, 1.0.1 and 1.0.2: Most logical data can be acquired from the phone Firmware 1.1.1, 1.1.2, 1.1.3, and 1.1.4: Only the /var/root/Media folder will be acquired Firmware Unlocked by a Jailbreaking Utility: Should
acquire most logical data depending on the unlocking software used. This is our first release for the Apple iPhone and we expect to see many more additions to this technology in the future. Keep your subscription
current to make sure you get all the new updates.
