Newer BOTs use more sophisticated command and control protocols. In many cases, BOTs use random port numbers, or “common” ones, so either you don’t know “where” it is, or, it’s mixed in with lots of legitimate traffic, so you can’t tell which connections are good and which ones are bad.

And worse yet, the firewall’s kernel core was found to contain an exploitable ring-0 heap-overflow. Specifically, I’ll discuss bypassing OS X specific anti-debugging mechanisms employed by the product, reverse-engineering the firewall’s I/O Kit kernel interfaces and ‘authentication’ mechanisms, and the discovery of the exploitable heap-overflow. Finally, methods of exploitation will be briefly discussed, including how an Apple kernel-fix made this previously un-exploitable bug, exploitable on OS X 10. Unfortunately bypassing this firewall’s network monitoring mechanisms is trivial. Little Snitch is the de facto personal firewall for OS X that aims to secure a Mac by blocking unauthorized network traffic.
