Elcomsoft Distributed Password Recovery Updated with OS X Keychain Support and Enhanced GPU AccelerationThursday, November 26th, 2015
We’ve just released the first major update to Elcomsoft Phone Viewer, our lightweight forensic tool for glancing over data extracted from mobile devices. Boosting version number to 2.0, we added quite a lot of things, making it a highly recommended update.
So what’s new in Phone Viewer 2.0? Improved compatibility with full support for iOS 9 backups (both local and iCloud). Support for media files (pictures and videos) with thumbnail gallery and built-in viewer. EXIF parsing and filtering with geolocation extraction and mapping. These things greatly enhance usage experience and add the ability to track subject’s coordinates on the map based on location data extracted from the images captured with their smartphone.
We have just released a brand new tool, and this time it’s not about mobile forensics. Or is it?
Elcomsoft Password Digger is designed for decrypting the content of Mac OS protected storage, the keychain. For one, it’s a Windows tool, so you’ll need to pull keychain files from the Mac OS system along with any decryption metadata (such as the key file for the system keychain or user’s password for decrypting the user keychain). After decrypting the keychain, we’ll export everything into an XML, and create a filtered plain-text file that only contains passwords (to be used as a pluggable dictionary in various password recovery tools).
So what is this all about?
Although we’ve already embraced the EFS-encryption/decryption in some of our white papers and case studies, now we’d like to share a video tutorial because seeing once is better than hearing reading twice. So, in this video you will see how to decrypt EFS-encrypted data with help of Advanced EFS Data Recovery and how to recover Windows user account password with Proactive System Password Recovery (because it’s still obligatory for this type of encryption).
Advanced EFS Data Recovery (AEFSDR) is wholly dedicated to decryption of Windows EFS-encrypted files, however in order to decrypt the data the program still requires the user account password. Yeah, you might think at first that anyone can decrypt the data having user account password at hand, but no. You can’t. EFS encryption uses more than just logon password, nonetheless it’s the core ingredient in data decryption and so it must be provided.
If you forgot the logon password or didn’t know it at all Proactive System Password Recovery (PSPR) in its turn can help you acquire all system passwords once you can log into the system with administrator privileges. Exactly this example has been illustrated in our video (provide by Sethioz), here it is:
With all the trouble of jailbreaking iOS 8 devices and the lack of support for 64-bit hardware, does iOS physical acquisition still present meaningful benefits to the investigator? Is it still worth your time and effort attempting to acquire that iPhone via a Lightning cord?
Granted, jailbroken iOS devices are rare as hen’s teeth. You are very unlikely to see one in the wild. However, we strongly believe that physical acquisition still plays an important role in the lab, and here are the reasons why.
- In many countries (Mexico, Brazil, Russia, East Europe etc.) Apple sells more 32-bit phones than 64-bit ones. Old iPhones traded in the US are refurbished and sold to consumers in other countries (BrightStar coordinates these operations for Apple in the US). As an example, new and refurbished iPhone 4S and 5 units accounted for some 46% of all iPhones sold through retail channels in Russia in Q1 2015.
- Physical extraction returns significantly more information compared to any other acquisition method including logical or over-the-air acquisition. In particular, we’re talking about downloaded mail and full application data including logs and cache files (especially those related to Internet activities). A lot of this information never makes it into backups.
- Full keychain extraction is only available with physical acquisition. Physical is the only way to fully decrypting the keychain including those records encrypted with device-specific keys. Those keychain items can be extracted from a backup file, but cannot be decrypted without a device-specific key. In addition, the keychain often contains the user’s Apple ID password.
- With physical acquisition, you can extract the ‘securityd’ (0x835) from the device. This key can be used to completely decrypt all keychain items from iCloud backups.
- Physical acquisition produces a standard DMG disk image with HFS+ file system. You can mount the image into the system and use a wider range of mobile forensic tools to analyze compared to iTunes or iCloud backup files.
Quite often our new customers ask us for advice about what they should start with in order to use the program effectively. In fact, there are various situations when the tool can come in handy by decrypting data securely protected with TrueCrypt, BitLocker (To-Go), or PGP and we’d need a super long video to describe all the cases. But we’d love to demonstrate one typical situation when disk is protected with TrueCrypt when entire system drive encryption option is on.
In this video, kindly provided by Sethioz, we suggest you to decrypt TrueCrypt whole system drive encryption using our Elcomsoft Forensic Disk Decryptor thoroughly going through all the stages starting from the very first one when you just got the encrypted hard drive on hands.
With encrypted hard drive in one hand and its memory dump in the other one (taken when encrypted disk was still mounted) we plug HDD into our “invesgitator’s” computer, start Elcomsoft Forensic Disk Decryptor and easily, in one slow motion, extract the encryption keys from the memory dump file and decrypt the protected HDD, either by mounting it into the “investigator’s” system (to be able to work with it on-the-fly) or by decoding the contents into a specified folder.
We hope you’ll enjoy this video and next time you have the necessity to decrypt something encrypted you’ll feel more confident about it. We also invite you to take a moment and share your experience here in comments or leave your question if you still have any after this pretty detailed video. 🙂
I know most computer gurus and pros never read through program manuals or help files and prefer to learn everything using proverbial method of trial and error. Does this sound like you? Of course. Exceptions are very seldom. So, here’s something nice that will save your time and help your experience with Elcomsoft Wireless Security Auditor (EWSA).
In order to provide a quick but sufficient understanding how to effectively work with EWSA, our friend Sethios has prepared a nice 20-minute video tutorial that includes all steps of work with the program starting with acquiring handshakes and moving on through all following steps.
This video is packed with useful information, so go ahead and watch it now:

Nowadays, computer data is everywhere around and it’s growing at amazing speeds from hour to hour. It’s really fast, easy and convenient to stay active online day and night. No matter how easy it may be for the user, for computer crime investigators, on the contrary, it is the toughest challenge to collect and decrypt digital evidence. Even more important for them is to be able to evaluate a particular situation and understand what exactly they can collect, where it may be stored, how quickly and effectively they can get hands on it leaving the data intact and authentic in order to keep it still useful and trustworthy in court.
The crime scene has also moved or better to say spread from computers to mobile devices that can not only “carry” but also produce, process and transfer valuable information among other mobile devices or even into the cloud. This introduces another big challenge, which is tracing a connection between various electronic devices, collecting necessary information from them and gathering evidence into one case.
A successful completion of the investigation requires a well thought-out and structured incident response scenario and a whole arsenal of tools, techniques and methods at hand that could be implemented quickly and effectively.
In the book by Mattia Epifani and Pasquale Stirparo you will find answers and guidelines to most of your questions in the field of mobile forensics in a very consistent and explicit manner. It also collects and exemplifies all useful tools on the market, including our key mobile forensics instruments Elcomsoft iOS Forensic Toolkit, Elcomsoft Phone Breaker and Elcomsoft Phone Viewer. We highly recommend Learning iOS Forensics guide with heavy emphasis on its practical side.
