Last month, it was determined that Dell has been shipping computers with a preinstalled digital certificate that would allow hackers to easily impersonate secure websites (like your bank's website)...
At this time, at least four models of Dell laptops and desktops (Inspiron, XPS, and older Precision and Latitude models) were shipping with this digitial certificate (issued by eDellRoot).
Basically, this digital certificate would allow someone to use the preinstalled certificate to extract the key to sign fake security certificates.
