Breaking Jetico BestCrypt

February 3rd, 2021 by Oleg Afonin

BestCrypt, developed by the Finnish company Jetico, is a cross-platform commercial disk encryption tool. Available for Windows, Linux, macOS and Android platforms, BestCrypt is delivered in two editions, one offering full-disk encryption and the other encrypting virtual disk volumes stored in containers, the latter being supported with our tools.

Shame on us, we somehow missed the whole issue about Apple dropping plan for encrypting backups after FBI complained, even mentioned in The Cybersecurity Stories We Were Jealous of in 2020 (and many reprints). In the meantime, the article is full of rumors, guesses, and unverified and technically dubious information. “Fake news”, so to say. Is there truth to the rumors, and what does Apple do and does not do when it comes to encrypting your personal information?

Reportedly, Apple dropped plan for encrypting backups after FBI complained. Apple’s decision will undoubtedly cause turmoil and will have a number of consequences. In this article, I want to talk about the technical reasons for encrypting or not encrypting cloud backup, and compare Apple’s approach with the data encryption strategies used by Google, who have been encrypting Android backups for several years.

Apple has long provided its users the tools to control how apps and Web sites use their personal data. The release of iOS 14 brought a number of new privacy features, while iOS 14.3 adds an important extra. At the same time, one of the most interesting privacy features is facing tough opposition from a group of digital advertising associations, making Apple postpone its implementation.

Accessing a locked system is always a challenge. Encrypted disks and encrypted virtual machines, encrypted files and passwords are just a few things to mention. In this article we are proposing a straightforward workflow for investigating computers in the field.

After publishing the first article in the series, we received numerous comments challenging our claims. We carefully reviewed every comment, reread and reevaluated our original article.  Elcomsoft vs. Hashcat Rev.1.1 is here.

How secure are your chats in your favorite instant messenger? Can someone intercept and read your secret conversations, and can you do something about it? Apple users have access to the highly popular instant messaging system, the iMessage. But how secure it really is? Let’s find out.

Apple iMessage is an important communication channel and an essential part of forensic acquisition efforts. iMessage chats are reasonably secure. Your ability to extract iMessages as well as the available sources of extraction will depend on several factors. Let’s discuss the factors that may affect your ability to extract, and what you can do to overcome them.

Today, we have an important date. It’s been 13 years since we invented a technique that reshaped the landscape of modern password recovery. 13 years ago, we introduced GPU acceleration in our then-current password recovery tool, enabling the use of consumer-grade gaming video cards for breaking passwords orders of magnitude faster.

Making tools for breaking passwords, I am frequently asked whether it’s legal, or how it works, or what one can do to protect their password from being cracked. There are people who have “nothing to hide”. There are those wearing tin foil hats, but there are a lot more people who can make a reasonable effort to secure their lives without going overboard. This article is for them.
