A security researcher has found a slew of fundamental problems with the way that modern browsers are designed and built. The research, done by Robert Hansen of SecTheory, shows that browsers such as Firefox, Internet Explorer and Chrome have a number of architectural problems that can essentially negate the security that SSL is meant to provide for sensitive Web transactions. The techniques that Hansen has developed, which he demonstrated at the Black Hat conference here Thursday, give an attacker the ability to do any number of nasty things to a target machine.
