Dell laptops are exposed to new security vulnerability involving a pre-installed root certificate which includes a private key. A hacker can launch an attack on a Dell laptop when the user logs into public WiFi network. By accessing the certificate, the attacker can impersonate websites, sign software and email messages, and even decrypt network traffic. On compromised systems, he can load malicious software too.
The intention of Dell by installing this certificate was to give effective personalized customer care support to their laptop users. Now Dell on their website has already released instructions to safely remove the certificate which is the path for this attack. It also emphasizes a software update.
