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.

BlackBerry Password Keeper Escrow Key: Have We Just Found a Hidden Backdoor?

As you may already know from the official press release, we’ve recently updated Elcomsoft Phone Breaker to version 4.10. From that release, you could learn that the updated version of the tool targets passwords managers, adding the ability to instantly decrypt passwords stored in BlackBerry Password Keeper for BlackBerry 10 and attack 1Password containers.

If you read along the lines though it’s a different story.

Essentially, we’ve discovered a backdoor hidden in recent versions of BlackBerry Password Keeper allowing us to decrypt the content of that app instantly without brute-forcing the master password. For our customers, this means instant access to passwords and other sensitive information maintained by BlackBerry Password Keeper. No lengthy waits and no fruitless attacks, just pure convenience. But is this convenience intentional? Did BlackBerry leave a backdoor for government access, or is this an unintentional vulnerability left by the company renowned for its exemplary security model? Let’s try to find out.
