Meet iOS 11.3: Apple to Make It Harder for Law Enforcement to Extract iPhone Data

Thursday, January 25th, 2018

Forget battery issues. Yes, Apple issued an apology for slowing down the iPhone and promised to add better battery management in future versions of iOS, but that’s not the point in iOS 11.3. Neither are ARKit improvements or AirPlay 2 support. There is something much more important, and it is gong to affect everyone.

Apple iOS is (and always was) the most secure mobile OS. FBI forensic expert called Apple “evil genius” because of that. Full disk encryption (since iOS 4), very reliable factory reset protection, Secure Enclave, convenient two-factor authentication are just a few things to mention. Starting with iOS 8, Apple itself cannot break into the locked iPhone. While in theory they are technically capable of creating (and signing, as they hold the keys) a special firmware image to boot the device, its encryption is not based on a hardware-specific key alone (as was the case for iOS 7 and older, and still the case for most Androids). Instead, the encryption key is also based on the user’s passcode, which is now 6 digits by default. Cracking of the passcode is not possible at all, thanks to Secure Enclave. Still, in come cases, Apple may help law enforcement personnel, and they at least provide some trainings to FBI and local police.


How to Extract Media Files from iOS Devices

Tuesday, January 9th, 2018

Media files (Camera Roll, pictures and videos, books etc.) are an important part of the content of mobile devices. The ability to quickly extract media files can be essential for an investigation, especially with geotags (location data) saved in EXIF metadata. Pulling pictures and videos from an Android smartphone can be easier than obtaining the rest of the data. At the same time, media extraction from iOS devices, while not impossible, is not the easiest nor the most obvious process. Let’s have a look at tools and techniques you can use to extract media files from unlocked and locked iOS devices.

Ways to Extract Media Files

There is more than one way you could use to extract media files. (more…)

What can be extracted from locked iPhones with new iOS Forensic Toolkit

Thursday, November 9th, 2017

Tired of reading on lockdown/pairing records? Sorry, we can’t stop. Pairing records are the key to access the content of a locked iPhone. We have recently made a number of findings allowing us to extract even more information from locked devices through the use of lockdown records. It’s not a breakthrough discovery and will never make front page news, but having more possibilities is always great.

Physical acquisition rules if it can be done. Physical works like a charm for ancient devices (up to and including the iPhone 4). For old models such as the iPhone 4s, 5 and 5c, full physical acquisition can still be performed, but  only if the device is already unlocked and a jailbreak can be installed. All reasonably recent models (starting with the iPhone 5s and all the way up to the iPhone 7 – but no 8, 8 Plus or the X) can be acquired as well, but for those devices all you’re getting is a copy of the file system with no partition imaging and no keychain. At this time, no company in the world can perform the full physical acquisition (which would include decrypting the disk image and the keychain) for iPhone 5s and newer.

The only way to unlock the iPhone (5s and newer) is hardware-driven. For iOS 7 and earlier, as well as for some early 8.x releases, the process was relatively easy. With iOS 9 through 11, however, it is a headache. There is still a possibility to enter the device into the special mode when the number of passcode attempts is not limited and one can brute-force the passcode, albeit at a very low rate of up to several minutes per passcode.

The worst about this method is its very low reliability. You can use a cheap Chinese device for trying passcodes at your own risk, or pay a lot of money to somebody else who will do about the same for you. Those guys do have more experience, and the risk is lower, but there still is no warranty of any kind, and you won’t get your money back if they fail.

There are other possibilities as well. We strongly recommend you to try the alternative method described below before taking the risk of “bricking” the device or paying big money for nothing.


The art of iOS and iCloud forensics

  • The rise and fall of physical acquisition
  • Jailbreak to the rescue
  • In the shade of iCloud
  • iCloud Keychain acquisition hits the scene

iOS 11 has arrived, now running on every second Apple device. There could not be a better time to reminiscent how iOS forensics has started just a few short years ago. Let’s have a look at what was possible back then, what is possible now, and what can be expected of iOS forensics in the future.


Can You Unlock That iPhone?

Monday, October 30th, 2017

“Can you unlock that iPhone?” is one of the most common questions we hear on various events and from our customers. There is no simple answer, but more often than not some options are available.

Just a few years back, the most common question was “can you crack that password?” We are still being asked that every other day, but locked iPhones are now more abundant than unknown passwords. There is a simple explanation for that: the iPhone is an ultimate source of evidence. That, before we even mention the many urgent cases when the phone needs to be unlocked.

Cover all possible scenarios in one short article would not be possible; for (much) more details you are welcome to read our Smartphone forensics book that explores the topic in depth. Keep reading to see what can be done in some cases.


How Can I Break Into a Locked iOS 10 iPhone?

Thursday, January 26th, 2017

Each iteration of iOS is getting more secure. With no jailbreak available for the current version of iOS, what acquisition methods are available for the iPhone 7, 7 Plus and other devices updating to iOS 10? How does the recent update of Elcomsoft iOS Forensic Toolkit help extracting a locked iOS 10 iPhone? Read along to find out!

iOS 10: The Most Secure iOS

When iOS 8 was released, we told you that physical acquisition is dead. Then hackers developed a jailbreak, and we came up with an imaging solution. Then it was iOS 9 that nobody could break for a while. The same thing happened: it was jailbroken, and we made a physical acquisition tool for it. Now it’s time for iOS 10.2 and no jailbreak (again). While eventually it might get a jailbreak, in the meanwhile there is no physical acquisition tool for iOS 10 devices. Considering that iPhone 7 and 7 Plus were released with iOS 10 onboard, your acquisition options for these devices are somewhat limited.

Plan “B”

With no jailbreak available for iOS 10, what are your options? If you have the latest Elcomsoft iOS Forensic Toolkit, use “plan B” instead!
