Eighteen Years of GPU Acceleration
November 27th, 2025 by Oleg Afonin
Eighteen years ago, before “GPU acceleration” and “AI data center” became household terms, a small hi-tech company changed the rules of cryptography. In 2007, we unveiled a radical idea – using the untapped power of graphics processors to recover passwords, which coincided with the release of video cards capable of performing fixed-point calculations. What began as an experiment would soon redefine performance computing across nearly every field.
Accelerating Password Recovery: GPU Acceleration, Distributed and Cloud Attacks
April 3rd, 2020 by Oleg Afonin
Modern encryption tools employ strong encryption with multiple hash iterations, making passwords extremely difficult to break. The November article “What is password recovery and how it is different from password cracking” explains the differences between instantly accessing protected information and attempting to break the original plain-text password. In that article, I briefly mentioned GPU acceleration and distributed attacks as methods to speed up the recovery. In this article, I’ll discuss the two acceleration techniques in more detail.
Password Reuse vs. Master Password: Two Sides of Password Managers
April 2nd, 2020 by Oleg Afonin
Password managers or password reuse? This is the question faced by most consumers. Reusing a password or its minor variations for different accounts has never been a good idea, yet in today’s world of online everything the rate of password reuse reaches astonishing values. Using a password manager helps reduce password reuse, supposedly offering increased security. In this article, we’ll perform forensic analysis of some of the most common password managers.
Using Microsoft Azure to Break Passwords
April 2nd, 2020 by Andrey Malyshev
Modern applications use highly secure and thus deliberately slow algorithms for verifying passwords. For this reason, the password recovery process may take a lot of time and require extreme computational resources. You can build your own powerful cluster to accelerate brute-force attacks, but if you only need to recover a password every once in a while, maintaining your own cluster may not be the best investment. Cloud services can help do a one-off job faster. For a long time, Elcomsoft Distributed Password Recovery had supported Amazon cloud services with automatic deployment on Amazon’s powerful GPU-accelerated servers. The latest update brings support for Microsoft Azure, adding the ability to automatically deploy Password Recovery Agents to virtual machines created in Microsoft Azure. In this article I will describe the deployment steps.
Tally ERP 9 Vault: How to Not Implement Password Protection
April 2nd, 2020 by Oleg Afonin
Tally ERP 9 is a “new-age business management software for new-age businesses” that is “tailor-made to delight”. With more than two million users, Tally is one of the most popular tools of its kind in India. The product includes the company’s implementation of secure storage named Tally Vault. How secure is Tally Vault, and what does one need to break in? In this article, we’ve provided some insights on how ElcomSoft researchers work when adding support for a new file format.
macOS, iOS and iCloud updates: forensic consequences
April 1st, 2020 by Vladimir Katalov
Every other day, Apple makes the work of forensic specialists harder. Speaking of iCloud, we partially covered this topic in Apple vs. Law Enforcement: Cloud Forensics and Apple vs Law Enforcement: Cloudy Times, but there is more to it today. The recent iOS (13.4) and macOS (10.15.4) releases brought some nasty surprises. Let’s talk about them.
Breaking VeraCrypt containers
March 31st, 2020 by Oleg Afonin
VeraCrypt is a de-facto successor to TrueCrypt, one of the most popular cryptographic tools for full-disk encryption of internal and external storage devices. Compared to TrueCrypt, which it effectively replaced, VeraCrypt employs a newer and more secure format for encrypted containers, and significantly expands the number of supported encryption algorithms and hash functions. Learn how to break VeraCrypt containers with distributed password attacks.
Attached Storage Forensics: Security Analysis of ASUSTOR NAS
March 25th, 2020 by Oleg Afonin
ASUSTOR advertises secure AES encryption with a 256-bit key. According to the manufacturer, AES-256 encryption is made available through the entire range of its current NAS devices. Unlike other manufacturers, ASUSTOR is very upfront regarding the type of encryption employed by its NAS devices: “ASUSTOR NAS offers folder based military grade AES 256-bit encryption”. As a result, we’re once again dealing with folder-based encryption running on top of the open-source encrypting file system eCryptfs. We’ve already seen eCryptfs-based encryption in attached storage devices made by Synology and TerraMaster. Does ASUSTOR have any surprises, or will its implementation of folder-based encryption suffer from the many restrictions and limitations? Let’s find out.
Full file system and keychain extraction: now with iOS 13 and iPhone 11 support
March 18th, 2020 by Vladimir Katalov
We recently introduced a new acquisition method for iPhone and iPad devices. The fast, simple and safe extraction agent requires no jailbreak, and delivers the full file system image and the keychain. The latest release of Elcomsoft iOS Forensic Toolkit expanded this method to iOS 13 and filled the gaps in some versions of iOS 12 that were missing support (such as iOS 12.3 and 12.4.1). Finally, we now officially support the latest generation of iPhone devices including the iPhone 11, iPhone 11 and iPhone 11 Pro. The new compatibility matrix becomes significantly more diverse with this release, so bear with us to learn which iOS devices can be extracted without a jailbreak.
Breaking Wi-Fi Passwords
March 6th, 2020 by Oleg Afonin
Modern wireless networks are securely protected with WPA/WPA2. The most frequently used method of securing access to a wireless network is pre-shared passphrase, or, simply put, a text password. The WPA standard enforces the minimum length of 8 characters for all Wi-Fi passwords. Considering the relatively low performance of WPA/WPA2 password attacks, brute force attacks are rarely effective even when performed with a network of GPU-accelerated computers. In this article, I will show how to attack wireless passwords for the purpose of security audit.
Why Mobile Forensic Specialists Need a Developer Account with Apple
March 5th, 2020 by Oleg Afonin
In our recent article iPhone Acquisition Without a Jailbreak I mentioned that agent-based extraction requires the use of an Apple ID that has been registered in Apple’s Developer Program. Participation is not free and comes with a number of limitations. Why do you need to become a “developer”, what are the limitations, and is there a workaround? Read along to find out.
