An ATI graphics card error helps malicious code to break into Vista

A serious security flaw in ATI graphics card drivers can be exploited by malicious code to help them bypass security barriers and break straight into the Windows Vista operating system kernel.

Developer Alex Ionescu was the one who discovered the ATI graphics card security error. And just a few hours after Ionescu found a bug, it released a Purple Pill error-exploiting tool that automatically downloads or doesn't load drivers on Vista.

The malicious code can be inserted directly here. The Purple Pill bypasses the dead muscle against Vista's rootkit by disabling the mechanism's ability to test device drivers.

Purple Pill broke into Vista by hiding itself on the security certificate (security certificate) built into the device driver software.

' What ATI needs to do now is to get a new security certificate, fix the vulnerability in the driver, and release it through Microsoft's Windows Update feature ,' said Ollie Whitehouse, a research expert. security of Symantec - identified.

' I think this error stems from the design and development of ATI device drivers .'

Microsoft and ATI are currently actively working together to find a solution to block the 'deadly' security breach as soon as possible.
