This article continues the series of publications aimed to help experts specify and build economical and power-efficient workstations for password recovery workloads. Electricity costs, long-term reliability and warranty coverage must be considered when building a password recovery workstation. In this article we will review the most common cooling solutions found in today’s GPUs, and compare consumer-grade video cards with their much lesser known professional counterparts.

This article opens the series of publications aimed to help experts specify and build effective and power-efficient workstations for brute-forcing passwords. Power consumption and power efficiency are two crucial parameters that are often overlooked in favor of sheer speed. When building a workstation with 24×7 workload, absolute performance numbers become arguably less important compared to performance per watt. We measured the speed and power consumption of seven video cards ranging from the NVIDIA Quadro T600 to NVIDIA RTX 3070 Ti and calculated their efficiency ratings.

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.

During the last several years, progress on the CPU performance front has seemingly stopped. Granted, last-generation CPUs are cool, silent and power-efficient. Anecdotal evidence: my new laptop (a brand new Macbook) is about as fast as the Dell ultrabook it replaced. The problem? I bought the Dell laptop some five years ago. Granted, the Dell was thicker and noisier. It’s battery never lasted longer than a few hours. But it was about as fast as the new Macbook.

We’ve recently updated Elcomsoft Distributed Password Recovery, adding enhanced GPU-assisted recovery for many supported formats. In a word, the new release adds GPU-accelerated recovery for OS X keychain, triples BitLocker recovery speeds, improves W-Fi password recovery and enhances GPU acceleration support for Internet Key Exchange (IKE).

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.
