Security Research Lab on Thursday said Microsoft’s Windows 7 release is prone to Firewire-based physical security attack such as Cold Boot Attacks derived from Windows Vista.

Hackers could steal and gain access to the data via a firewire-based physical security attack, according to the paper.

“I was successfully able to bypass the Windows 7 RTM authentication code and logon with any password.”
It can also bypass Windows Encrypted File System (EFS), if a user is logged on and the system is running or in standby mode.

However, as a result, researchers had developed a software program against the Firewire-based physical security attack on Windows systems discuss here.
