Windows 7 Firewire Attacks and Defense Techniques

Windows 7 systems are susceptible to Firewire-based attacks as well, as the Security Research Lab demonstrates. Besides a description how password authentication can be bypassed through memory manipulation via Firewire ports, the implications on BitLocker, Encrypted File System (EFS) and Windows Domains are described as well. A whitepaper can be downloaded here:

In the course of analysis, a software defense against Firewire-based attacks on Windows systems was developed, which is described in a second whitepaper:

The software is free for personal use – use at your own risk:
