Hashcat is a great, free tool competing head to head with the tools we make. We charge several hundred dollars for what, in the end, can be done with a free tool. What are the reasons for our customers to choose ElcomSoft products instead of Hashcat, and is the expense justified? We did our best to compare the two tools to help you make the informed decision.

It’s Hashed, Not Encrypted

September 9th, 2020 by Oleg Afonin

How many times have you seen the phrase: “Your password is securely encrypted”? More often than not, taking it at face value has little sense. Encryption means the data (such as the password) can be decrypted if you have the right key. Most passwords, however, cannot be decrypted since they weren’t encrypted in the first place. Instead, one might be able to recover them by running a lengthy attack. Let’s talk about the differences between encryption and hashing and discuss why some passwords are so much tougher to break.

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.

Why wasting time recovering passwords instead of just breaking in? Why can we crack some passwords but still have to recover the others? Not all types of protection are equal. There are multiple types of password protection, all having their legitimate use cases. In this article, we’ll explain the differences between the many types of password protection.

Home users and small offices are served by two major manufacturers of network attached storage devices (NAS): QNAP and Synology, with Western Digital being a distant third. All Qnap and Synology network attached storage models are advertised with support for hardware-accelerated AES encryption. Encrypted NAS devices can be a real roadblock on the way of forensic investigations. In this article, we’ll review the common encryption scenarios used in home and small office models of network attached storage devices made by Synology. (more…)

The first Microsoft Office product was announced back in 1988. During the past thirty years, Microsoft Office has evolved from a simple text editor to a powerful combination of desktop apps and cloud services. With more than 1.2 billion users of the desktop Office suite and over 60 million users of Office 365 cloud service, Microsoft Office files are undoubtedly the most popular tools on the market. With its backward file format compatibility, Microsoft Office has become a de-facto standard for documents interchange.

Full-disk encryption presents an immediate challenge to forensic experts. When acquiring computers with encrypted system volumes, the investigation cannot go forward without breaking the encryption first. Traditionally, experts would remove the hard drive(s), make disk images and work from there. We are offering a faster and easier way to access information required to break full-disk system encryption by booting from a flash drive and obtaining encryption metadata required to brute-force the original plain-text passwords to encrypted volumes. For non-system volumes, experts can quickly pull the system’s hibernation file to extract on-the-fly encryption keys later on with Elcomsoft Forensic Disk Decryptor.

Health data is among the most important bits of information about a person. Health information is just as sensitive as the person’s passwords – and might be even more sensitive. It is only natural that health information is treated accordingly. Medical facilities are strictly regulated and take every possible security measure to restrict access to your medical records.

We’ve just updated Elcomsoft Distributed Password Recovery with the ability to break master passwords protecting encrypted vaults of the four popular password keepers: 1Password, KeePass, LastPass and Dashlane. In this article, we’ll talk about security of today’s password managers, and provide insight on what exactly we did and how to break in to encrypted vaults. (more…)

This article opens a new series dedicated to breaking passwords. It’s no secret that simply getting a good password recovery tool is not enough to successfully break a given password. Brute-force attacks are inefficient for modern formats (e.g. encrypted Office 2013 documents), while using general dictionaries can still be too much for speedy attacks and too little to actually work. In this article, we’ll discuss the first of the two relatively unknown vectors of attack that can potentially break 30 to 70 per cent of real-world passwords in a matter of minutes. The second method will be described in the follow-up article. (more…)
