Man-in-the-Middle Attacks on Lenovo Computers
It’s not just national intelligence agencies that break your https security through man-in-the-middle attacks. Corporations do it, too. For the past few months, Lenovo PCs have shipped with an adware app called Superfish that man-in-the-middles TLS connections.
And you should get rid of it, not merely because it’s nasty adware. It’s a security risk. Someone with the password—here it is, cracked—can perform a man-in-the-middle attack on your security as well.
Superfish, as well, exhibited extreme cluelessness by claiming its sofware poses no security risk. That was before someone cracked its password, though.
