Microsoft flaw allows USB loaded with payload to bypass security controls

This flaw allows anyone with a USB thumb drive loaded with the payload to bypass security controls and access a vulnerable system even if AutoRun is disabled, and the screen is locked. Flaw exposes your Windows PCs to major risk. If you remember Stuxnet, worm was injected to Iran's nuclear program system using USB thumb drive.

Windows typically discovers USB devices when they are inserted or when they change power sources (if they switch from plugged-in power to being powered off of the USB connection itself).
