“SniffJoke (Sj) implements a set of anti sniffing technology itself, but begins developed as a modular framework.
Will easily be supported by a security community that want to exploit and explore sniffing faults. SniffJoke is an application for Linux that handle transparently your TCP connection, delaying, modifying and injecting fake packets inside your transmission, make them almost impossible to be correctly read by a passive wiretapping technology (IDS or sniffer). An internet client running SniffJoke injects in the transmission flow some packets able to seriously disturb passive analysis like sniffing, interception and low level information theft. No server supports needed!“
