Attacking the 1Password Master Password Follow-Up

Friday, August 18th, 2017

We received some great feedback on the original article about attacking master passwords of several popular password managers. In one discussion, our benchmark numbers for 1Password were questioned. We had no choice but to re-run the benchmarks and publish an updated chart along with some technical details and explanations. We bring our apologies to AgileBits, the developers of 1Password, for letting the wrong number creep in to our benchmark. Can we still break into 1Password by attacking the master password? Please bear with us for up-to-date information and detailed technical discussion.

We must make one thing extremely clear: this time we did not “hack” anything. We are using good old brute force, enhanced with GPU acceleration, to attack the user’s plain-text master password protecting password managers’ encrypted databases. The four password managers were and still remain secure providing that the user opts for a strong master password. If a truly secure master password is used, it would not be possible to break it within reasonable timeframe.

Breaking Passwords in the Cloud: Using Amazon P2 Instances

Tuesday, August 1st, 2017

Cloud services such as Amazon EC2 can quickly deliver additional computing power on demand. Amazon’s recent introduction of the a type of EC2 Compute Units made this proposition much more attractive than ever before. With Elcomsoft Distributed Password Recovery now supporting Amazon’s new P2 instances, each with up to 16 GPU units, users can get as much speed as they need the moment they need. In this article, we’ll discuss the benefits of using cloud compute units for password recovery, and provide a step-by-step guide on how to add virtual instances to Elcomsoft Distributed Password Recovery.

How to Break 70% of Passwords in Minutes

Tuesday, February 14th, 2017

According to surveys, the average English-speaking consumer maintains around 27 online accounts. Memorizing 27 unique, cryptographically secure passwords is nearly impossible for a person one could reasonably call “average”. As a result, the average person tends to reuse passwords, which means that a single password (or its simple variations) can be used to protect multiple online accounts and services. The same passwords are very likely to be chosen to protect access to offline resources such as encrypted archives and documents. In fact, several independent researches published between 2012 and 2016 suggest that between 59 and 61 per cent of consumers reuse passwords.

Considering how consistent the numbers are between multiple researches carried out over the course of four years, we can safely assume that around 60% of consumers reuse their passwords. How can this data help us break passwords, and how did we arrive to the value of 70% in the title? Read along to find out! (more…)

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…)

Elcomsoft Distributed Password Recovery Video Tutorial

Thursday, February 26th, 2015

Anyone considering the possibility to purchase Elcomsoft Distributed Password Recovery has a wonderful opportunity to explore the program together with Sethioz and get a clearer understanding of how the program works and what requires your special attention when you are using EDPR. This video assumes you are already familiar with basics of password cracking and suggests more information for your convenient work with the tool.

This is a very detailed tutorial showing how to prepare EDPR for work, which includes setting up connection between server and agents via local host or Internet, selecting the right IP address, paying attention to the fact that server’s and agent’s versions should be the same (users often neglect this fact), choosing a task, choosing the right attack options (they are all sufficiently explained), using side monitoring tools, checking your GPU temperature and utilization percentage on all connected computers and so on. So, let’s watch it now.

If you had any questions watching this video or would like to share your own experience using EDPR you are welcome to continue the topic here in comments.

Cracking Wi-Fi Passwords with Sethioz

Wednesday, February 18th, 2015

If you care about password cracking, hardware acceleration or Wi-Fi protection this interview with our friend Sethioz is certainly for you. Being currently a freelance security tester Sethioz kindly shared his experience in cracking passwords using video cards, which in its turn derived from his gaming interest in cards. His personal experience may be very helpful to those whose concern about password cracking is not trivial.

How did it all start or what was the reason to try to find a Wi-Fi password?

There is no short answer to this, if there would be, I guess it would be “curiosity”. I think I got my first computer somewhere in 2002-2003 (my own PC) and ever since I’ve been interested in everything that is not “normal”, such as reverse engineering, debugging, hacking games, cracking password etc. (more…)
