Go ahead and poo poo the overdone marketing of the Badlock vulnerability. With its fire-engine-red logo and a dedicated website that went live more than a month before the release of any patches, claims the risk was shamelessly hyped are justified.

In a nutshell, Badlock refers to a defect in a security component contained in just about every version of the Windows and Linux operating systems.
