Introduction

Elcomsoft Wireless Security Auditor (EWSA) is a tool for network administrators and IT security specialists allowing to audit security of the company's wireless networks by attempting an attack on Wi-Fi passwords. Built-in Wi-Fi sniffer and GPU-accelerated recovery ensure the highest-performance attack on WPA/WPA2-PSK passwords. Elcomsoft Wireless Security Auditor supports dictionary attacks with an advanced variation facility. The built-in wireless sniffer allows intercepting wireless traffic using general Wi-Fi adapters as well as AirPCap sticks. The tool can also accept standard tcpdump logs supported by any Wi-Fi sniffer.

Periodic audits of network security policies are necessary to ensure secure production environment. Wireless networks can only provide sufficient security when configured properly. Supporting both WPA and WPA2 security standards, Elcomsoft Wireless Security Auditor can audit all kinds of Wi-Fi networks by attempting to recover WPA-PSK (Pre-Shared Key) and WPA2-PSK passwords.

Elcomsoft Wireless Security Auditor comes with a custom-built Wi-Fi sniffer that can work on ordinary Wi-Fi adapters via a custom NDIS driver (32-bit and 64-bit versions are supplied). AirPCap adapters are also supported. The built-in wireless sniffer intercepts the handshake packet required to start the attack. WinPCap drivers are required to enable Wi-Fi sniffing.

ElcomSoft’s patented GPU acceleration makes Wi-Fi password recovery several hundred times faster by using the sheer computational power of today’s NVIDIA and AMD video cards. GPU acceleration delivers supercomputer-grade performance with minimum investment. Multiple video cards can be used together for even faster attacks.

Elcomsoft Wireless Security Auditor supports fully automatic and manual operation, allowing to enter password hashes and network's SSID by hand. Retrieving all SSID and password hashes from handshake packets, Elcomsoft Wireless Security Auditor allows selecting which one to recover. In order to test network security from insider attacks, Elcomsoft Wireless Security Auditor can automatically import saved password hashes retrieved by Elcomsoft Proactive System Password Recovery.
