ATI Driver Flaw Exposes Vista Kernel To Attackers
Apparently an unpatched flaw in an ATI driver allows hackers to load unsigned drivers onto Vista. The flaw was at the center of the Purple Pill proof-of-concept tool that exposed a way to tamper with the Windows Vista kernel.
Apparently an unpatched flaw in an ATI driver allows hackers to load unsigned drivers onto Vista. The flaw was at the center of the Purple Pill proof-of-concept tool that exposed a way to tamper with the Windows Vista kernel.
Purple Pill, a utility released by Alex Ionescu and yanked an hour later after the kernel developer realized that the ATI driver flaw was not yet patched, provided an easy way to load unsigned drivers onto Vista — effectively defeating the new anti-rootkit/anti-DRM mechanism built into Microsoft's newest operating system.
