iOS Logical Acquisition: The Last Hope For Passcode-Locked Devices?

Thursday, August 11th, 2016

For many months, a working jailbreak was not available for current versions of iOS. In the end of July, Pangu released public jailbreak for iOS 9.2-9.3.3. A few days ago, Apple patched the exploit and started seeding iOS 9.3.4. This was the shortest-living jailbreak in history.

With iOS getting more secure with each generation, the chance of successfully jailbreaking a device running a recent version of iOS are becoming slim. While this may not be the end of all for mobile forensic experts, we felt we need to address the issue in our physical acquisition toolkit.

NVIDIA Pascal: a Great Password Cracking Tool

Tuesday, July 26th, 2016

During the last several years, progress on the CPU performance front has seemingly stopped. Granted, last-generation CPUs are cool, silent and power-efficient. Anecdotal evidence: my new laptop (a brand new Macbook) is about as fast as the Dell ultrabook it replaced. The problem? I bought the Dell laptop some five years ago. Granted, the Dell was thicker and noisier. It’s battery never lasted longer than a few hours. But it was about as fast as the new Macbook.

Computer games have evolved a lot during the last years. Demanding faster and faster video cards, today’s games are relatively lax on CPU requirements. Manufacturers followed the trend, continuing the performance race. GPUs have picked up where CPUs have left.

NVIDIA has recently released a reference design for GTX 1080 boards based on the new Pascal architecture. Elcomsoft Distributed Password Recovery 3.20 adds support for the new architecture. What does it mean for us?

Elcomsoft Phone Viewer 2.20 Goes Stand-Alone

Thursday, June 23rd, 2016

We have a bunch of mobile forensic tools. We have tools for extracting data from jailbroken iPhones and tools for decrypting password-protected backups. Tools for downloading data from iCloud and tools for analyzing user data mined by Google. We even have a tool for decrypting backups produced by BlackBerry 10, one of the most secure OS’es on the market.

We also have a tool for viewing all that data. Elcomsoft Phone Viewer was initially released as a tool to complement our range of mobile forensic tools. Initially, the tool’s sole purpose was enabling our users to view information they extracted using other tools from our range via physical, logical or over-the-air acquisition. Viewing all but unencrypted iTunes backups would require you launching Elcomsoft Phone Breaker to remove protection and decrypt information.

This is no longer the case. Starting with this release, you can use Elcomsoft Phone Viewer as a fully featured, stand-alone tool for accessing mobile data. What did we change and who can benefit from the new features? Read along to find out!

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)

Apple Two-Factor Authentication vs. Two-Step Verification

Friday, April 1st, 2016

Two-step verification and two-factor authentication both aim to help users secure their Apple ID, adding a secondary authentication factor to strengthen security. While Apple ID and password are “something you know”, two-step verification (and two-factor authentication) are both based on “something you have”.

However, Apple doesn’t make it easy. Instead of using a single two-factor authentication solution (like Google), the company went for two different processes with similar usability and slightly different names. What are the differences between the two verification processes, and how do they affect mobile forensics? Let’s try to find out.

Hacking For Dummies by Kevin Beaver (5th edition)

Friday, January 29th, 2016

HFDIt is our greatest pleasure to recommend the newest edition of “Hacking For Dummies” by Kevin Beaver, an independent IT security consultant, a practical guide on computer and mobile security updated to the current state of industry. With a natural talent of word Kevin easily guides you through security issues in a very clear and consistent manner, so that all major aspects of IT security, authentication and pen-testing are covered. With such a harmonious and sequential unveiling of security subjects as in this book, it is much easier to dig deeper into particular questions of your own interest.

We know Kevin Beaver from long ago, since that very happy moment when he decided to check out our software and see how it works. Having tried all our tools and providing professional feedback Kevin immensely contributed towards our software developments.

Now it’s a great honor for us to be mentioned in various editions of his book, including the latest one, with reference to practically all of our programs, primarily because they are all meant for getting access to password protected data or encrypted disks and crypto containers. Reverse engineering and data decryption is our main focus since the very beginning of the company. However, lately the focus of our attention has been slowly drifting more “into the cloud” taking the shape of such products as Elcomsoft Explorer for WhatsApp or Elcomsoft Cloud eXplorer for Google Accounts. And it is not a coincidence that Kevin’s book covers cloud security topic as well. So, get these 408 pages of hacks and tips against them right meow and enjoy your reading.
