Homeland Security Tells Lenovo Users to Remove Program

The U.S. government advised Lenovo Group Ltd customers to remove a "Superfish," a program pre-installed on some Lenovo laptops, saying it makes users vulnerable to cyberattacks. The Department of Homeland Security said in an alert that the program makes users vulnerable to a type of cyberattack known as SSL spoofing, in which remote attackers can read encrypted web traffic, redirect traffic from official websites to spoofs, and perform other attacks.
