I’ve Got the iTunes Backup from the iCloud. What Shall I Do Now?

Tuesday, September 3rd, 2013

This is the second part of Elcomsoft Phone Password Breaker Enhances iCloud Forensics and Speeds Up Investigations article.

Extracting the content of an iPhone is only half the job. Recovering meaningful information from raw data is yet another matter. The good news is there are plenty of powerful tools providing iOS analytics. The bad news? You’re about to spend a lot of time analyzing the files and documenting the findings. Depending on the purpose of your investigation, your budget and your level of expertise using forensic tools, you may want using one tool or the other. Let’s see what’s available.

Explaining that new iCloud feature

Tuesday, May 29th, 2012

It’s been almost two weeks since we have released updated version of Elcomsoft Phone Password Breaker that is capable of downloading backups from the iCloud and we have seen very diverse feedback ever since. Reading through some articles or forum threads it became quite evident that many just do not understand what we have actually done and what are the implications. So I am taking another try to clarify things.

Newer iOS Forensic Toolkit Acquires iPhones in 20 Minutes, Including iOS 5

Tuesday, November 1st, 2011

iOS 5 Support

When developing the iOS 5 compatible version of iOS Forensic Toolkit, we found the freshened encryption to be only tweaked up a bit, with the exception of keychain encryption. The encryption algorithm protecting keychain items such as Web site and email passwords has been changed completely. In addition, escrow keybag now becomes useless to a forensic specialist. Without knowing the original device passcode, escrow keys remain inaccessible even if they are physically available.

What does enhanced security mean for the user? With iOS 5, they are getting a bit more security. Their keychain items such as Web site, email and certain application passwords will remain secure even if their phone falls into the hands of a forensic specialist. That, of course, will only last till the moment investigators obtain the original device passcode, which is only a matter of time if a tool such as iOS Forensic Toolkit is used to recover one.

What does this mean for the forensics? Bad news first: without knowing or recovering the original device passcode, some of the keychain items will not be decryptable. These items include Web site passwords stored in Safari browser, email passwords, and some application passwords.

Now the good news: iOS Forensic Toolkit can still recover the original plain-text device passcode, and it is still possible to obtain escrow keys from any iTunes equipped computer the iOS device in question has been ever synced or connected to. Once the passcode is recovered, iOS Forensic Toolkit will decrypt everything from the keychain. If there’s no time to recover the passcode or escrow keys, the Toolkit will still do its best and decrypt some of the keychain items.

Faster Operation

Besides adding support for the latest iOS 5, Elcomsoft iOS Forensic Toolkit becomes 2 to 2.5 times faster to acquire iOS devices. When it required 40 to 60 minutes before, the new version will take only 20 minutes. For example, the updated iOS Forensic Toolkit can acquire a 16-Gb iPhone 4 in about 20 minutes, or a 32-Gb version in 40 minutes.

Elcomsoft iOS Forensic Toolkit highlighted in SANS Information Security Reading Room

Monday, August 15th, 2011

SANS Information Security Reading Room has recently publicized a whitepaper about iOS security where they mentioned our software – Elcomsoft iOS Forensic Toolkit – in a section about encryption. Kiel Thomas, the author of the whitepaper, explained one more time the main principles of iOS 4 encryption, which became stronger in comparison with iOS 3.x and how our toolkit can bypass new strong algorithms.

In its next part about iTunes Backups Kiel touches upon Elcomsoft Phone Password Breaker which virtually crunches backup passwords at speed of 35000 passwords per second (with AMD Radeon HD 5970) using both brute force and dictionary attacks, here are some benchmarks.

It seems the paper does not miss out on any nuance about iOS 4 and provides practical advice to either avoid or prevent from the depressing outcomes, such as loss of data. Closer to the end of the paper you will also find several sagacious tips for using the devices within organizations, including passcode management, a so called “first line of defense” which according Kiel’s view “can be matched to existing password policies”, however he inclines to use passwords instead of 4 digit passcodes.

And in conclusion the author discovers that smartphone and tablet security measurements resemble the ones of laptops, because they all belong to mobile devices.  Find out more details in the source itself: http://www.sans.org/reading_room/whitepapers/pda/security-implications-ios_33724
 

iOS Forensic Toolkit: Keychain Decryption, Logical Acquisition, iOS 4.3.4, and Other Goodies

Monday, July 25th, 2011
 
You might have heard about our new product – iOS Forensic Toolkit. In fact, if you are involved in mobile phone and smartphone forensics, you almost certainly have. In case our previous announcements haven’t reached you, iOS Forensic Toolkit is a set of tools designed to perform physical acquisition of iPhone/iPad/iPod Touch devices and decrypt the resulting images. This decryption capability is unique and allows one to obtain a fully usable image of the device’s file system with the contents of each and every file decrypted and available for analysis. And the fact is, with today’s update, iOS Forensic Toolkit is much more than just that.

Extracting the File System from iPhone/iPad/iPod Touch Devices

Monday, May 23rd, 2011

In our previous blog post we have described how we broke the encryption in iOS devices. One important thing was left out of that article for the sake of readability, and that is how we actually acquire the image of the file system of the device. Indeed, in order to decrypt the file system, we need to extract it from the device first.

ElcomSoft Breaks iPhone Encryption, Offers Forensic Access to File System Dumps

Monday, May 23rd, 2011

ElcomSoft researchers were able to decrypt iPhone’s encrypted file system images made under iOS 4. While at first this may sound as a minor achievement, ElcomSoft is in fact the world’s first company to do this. It’s also worth noting that we will be releasing the product implementing this functionality for the exclusive use of law enforcement, forensic and intelligence agencies. We have a number of good reasons for doing it this way. But first, let’s have a look at perspective.
