![]() ![]() In this case as well as the application validating the user (not much use if the application is rogue)-the users devices validates the application-hence distinguishing rogue applications from genuine applications ![]() PKI mutual authentication The main defence in a PKI scenario is mutual authentication.Strong encryption (as opposed to relying on small symmetric or asymmetric key sizes, broken ciphers or unproven ciphers).Various defenses against MITM attacks use authentication techniques that include: When victim browse a website, attacker will know the address victim visited. URLSnarf outputs all requested URLs sniffed from HTTP traffic in CLF (Common Log Format, used by almost all web servers), suitable for offline post-processing with your favorite web log analysis tool (analog, urlsnarf -i eth0Īnd URLSnarf will start capturing all website address visited by victim machine. URLSnarf is a tool that can sniff HTTP requests in Common Log Format. ![]() When victim browse a website with image, DriftNet will capture all image traffic as shown in the screen-shot below. ![]() Use the following command to run DriftNet driftnet -i eth0 Now we can try to use DriftNet to monitor all victim image traffic. In an experimental enhancement, DriftNet now picks out MPEG audio streams from network traffic and tries to play them. Fun to run on a host which sees lots of web traffic. Inspired by EtherPEG (though, not owning an Apple Macintosh, I’ve never actually seen it in operation), DriftNet is a program which listens to network traffic and picks out images from TCP streams it observes. Use DriftNet to Monitor packets and images
