More Tricks for Defeating SSL

Architecture and Background

More Tricks For Defeating SSL Moxie Marlinspike This talk aims to pick up where SSL stripping left off.

Vulnerability Analysis

While sslstrip ultimately remains quite deadly in practice, this talk will demonstrate some new tricks for defeating SSL/TLS in places where sslstrip does not reach.

Exploitation and Demonstrations

Cautious users, for example, have been advised to explicitly visit https URLs or to use bookmarks in order to protect themselves from sslstrip, while other SSL/TLS based protocols such as imaps, pop3s, smtps, ssl/irc, and SSL-based VPNs never present an opportunity for stripping.

Remediation and Defensive Strategies

This talk will outline some new tools and tricks aimed at these points of communication, ultimately providing highly effective attacks on SSL/TLS connections themselves.
