Elcomsoft System Recovery UEFI Support

Thursday, June 16th, 2016

As you may already know, we’ve released an update to Elcomsoft System Recovery, a tool allowing to reset or recover Windows and Microsoft Account passwords by booting from an external USB drive. The new build allows creating bootable USB drives for devices exclusively relying on UEFI bootloaders. Why was this change needed? Read below for an answer!

UEFI Boot Support

If you need access to Windows protected files (and files containing password hashes are always protected), you will either require administrative privileges or must boot a separate copy of Windows from a separate boot media. Elcomsoft System Recovery has always come with the ability to create such bootable media.

As computers evolved, industry moved to 64-bit computations. During the last decade, CPU manufacturers migrated completely to 64-bit architecture. Some years later, it became obvious that legacy BIOS was no longer relevant in the new age. BIOS was superseded with UEFI.

To maintain compatibility with legacy operating systems, most systems of that time period came with support for legacy boot mode (BIOS emulation, “compatibility mode”) enabled out of the box. As operating systems evolved, manufacturers started gradually phasing out legacy support. Today we have reached the point where many new devices (2013 and newer) come without any sort of BIOS emulation at all.

Elcomsoft System Recovery comes with a customized bootable Windows PE environment. By booting from this media, customers can gain access to existing Windows installations even if they don’t know the correct password. For a long time, Elcomsoft System Recovery was relying on legacy compatibility mode to boot. This is no longer an option. The increased share of devices shipping without BIOS emulation or legacy boot support required us to adapt.

Breaking BitLocker Encryption: Brute Forcing the Backdoor (Part I)

Wednesday, June 8th, 2016

Investigators start seeing BitLocker encrypted volumes more and more often, yet computer users themselves may be genuinely unaware of the fact they’ve been encrypting their disk all along. How can you break into BitLocker encryption? Do you have to brute-force the password, or is there a quick hack to exploit?

We did our research, and are ready to share our findings. Due to the sheer amount of information, we had to break this publication into two parts. In today’s Part I, we’ll discuss the possibility of using a backdoor to hack our way into BitLocker. This publication will be followed by Part II, in which we’ll discuss brute-force possibilities if access to encrypted information through the backdoor is not available. (more…)

Dealing with a Locked iPhone

Friday, April 15th, 2016

So you’ve got an iPhone, and it’s locked, and you don’t know the passcode. This situation is so common, and the market has so many solutions and “solutions” that we felt a short walkthrough is necessary.

What exactly can be done to the device depends on the following factors:

Hardware Generation

iphone2

From the point of view of mobile forensics, there are three distinct generations:

  1. iPhone 4 and older (acquisition is trivial)
  2. iPhone 4S, 5 and 5C (32-bit devices, no Secure Enclave, jailbreak required, must be able to unlock the device)
  3. iPhone 5S, 6/6S, 6/6S Plus and newer (64-bit devices, Secure Enclave, jailbreak required, passcode must be known and removed in Settings)

What Google Knows About You, and Why It Matters

Tuesday, December 22nd, 2015

In today’s thoroughly connected world, everyone shares at least some of their personal information with, well, strangers. Voluntarily or not, people using personal computers or mobile devices have some of their information transmitted to, processed, stored and used by multiple online service providers.

Took a selfie shot? Your face (and possibly your friends’ faces) will be marked, and the photo will be uploaded to one or another cloud storage provider on your behalf. Used your phone to look up a place to eat? Your search will be remembered and used later on to push you suggestions next time when you’re around. Emails and messages that you write, persons you communicate with, your comprehensive location history and all the photos you shoot (accompanied with appropriate geotags) are carefully collected, processed and stored. Web sites you visit along with logins and passwords, your complete browsing history and pretty much everything you do with your phone can and probably will be recorded and used on you to “enhance your experience”.

Some service providers collect more information than others. Google appears to be the absolute champion in this regard. Being a major service provider penetrating into every area of our lives, Google collects, stores and processes overwhelming amounts of data.

A New Tool for WhatsApp Acquisition

Wednesday, November 25th, 2015

We have recently released a brand new product, Elcomsoft Explorer for WhatsApp. Targeted at home users and forensic experts along, this Windows-based, iOS-centric tool offers a bunch of extraction options for WhatsApp databases. Why the new tool, and how is it different from other extraction options offered by Elsomsoft’s mobile forensic tools? Before we move on to that, let’s have a look at the current state of WhatsApp.

Physical Acquisition for 64-bit Devices, iOS 9 Support

Wednesday, November 18th, 2015

Big news! iOS Forensic Toolkit receives its first major update. And it’s a big one. Not only does version 2.0 bring support for iOS 9 handys. We also expanded acquisition support for jailbroken devices, enabling limited data extraction from jailbroken devices locked with an unknown passcode.

Last but not least. For the first time ever, we’ve added physical acquisition support for 64-bit devices! We’ve done what was long considered to be impossible. Intrigued? Read along to find out! Can’t wait to see what can be done to 64-bit iDevices? Skip right to that section!

New in EIFT 2.0

  • iOS 9: Full physical acquisition support of jailbroken 32-bit devices running iOS 9
  • 64-bit: Physical acquisition for jailbroken 64-bit devices running any version of iOS
  • Locked: Limited acquisition support for jailbroken 32-bit and 64-bit iOS devices that are locked with an unknown passcode and cannot be unlocked

It’s probably a bit too much for a modest one-digit version bump… we should’ve named this version 3.0! (more…)

Elcomsoft Phone Viewer: iOS 9, Media Gallery and Location Tracking

Wednesday, November 11th, 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.

Digging Mac OS Keychains

Wednesday, September 16th, 2015

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?
