What's SniffJoke ?
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!
 
Why is this possible ?
 
The internet protocols have been developed to allow two elements to communicate, not some third-parts to intercept their communication. This will happen, but the communication system has been not developed with this objective.
SniffJoke uses the network protocol in a permitted way, exploiting the implicit difference of network stack present in an operating system respect the sniffers dissector.

Why has it been developed ?
 
Because too many people believe that the only way to obtain self-security is through control, I don't want to tell them they are wrong, but controlling internet is impossibile, if you want not to be controlled. It is obvious that you should not trust a security control that could be bypassed, isn't it?

When you understand this, remember that the progressive acceptance of the control measure has been treated like a "necessary sacrifice". when you realize that this security method don't bring security, but only possibile abuses, you will be ready to stop accepting this useless sacrifice.
 
What's SniffJoke don't protect from
 
If you are using a nontrusted third part (facebook?) it doesn't matter how much your data is encrypted, scrambled or whatever: your data is in facebook store. Unprotected and presented. If you use a trojanized box, it's the same, it's like have an invisible and weightless watchers sit on your legs, transcribing everything you're doing. SniffJoke protects from: a sniffer in your network, a sniffer in the provider flow, a sniffer in the destination network.
 
Security and social GOALs
 
Various goals SniffJoke aim to achieves. Information security, will not be control based, almost, not in traffic and data passive analysis, because Internet technology is not engineered with this capability. Passive wiretapping is not only used by law enforcement (they have a lot of other technology in their dispositions); Wiretapping technology is widespread and usable by every entities, not for your safety, but for the value derived from your data.
 
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 support is needed!

The internet protocols have been developed to allow two elements to communicate, not some third-parts to intercept their communication. This will happen, but the communication system has been not developed with this objective. SniffJoke uses the network protocol in a permitted way, exploiting the implicit difference of network stack present in an operating system respect the sniffers dissector.

How Does It Work?

It works only under Linux (at the moment), creates a fake default gateway in your OS (the client or a default gateway) using a TUN interface check every traffic passing thru it, tracks every session and  applyies two concepts: the scramble and the hack.
The scramble is the technology to bring:
  1. A sniffer to accept as true a packet who will be discarded by the server, or
  2. A sniffer to drop a packet who will be accepted by the server.
The scramble technology brings in desynchronisation between the sniffer flow and the real flow.

The bogus packet accepted by the sniffer is generated by the “plugin” is a C++ simple class, which in a pseudo statefull tracking will forge the packet to be injected inside the flow. is pretty easy to develop
anew one, and if someone wants to make research on sniffers attack (or fuzzing the flow searching for bugs) need to make the hand inside its.

The configuration permits to define blacklist/whitelist ip address to scramble, a degree of aggressivity for each port, which plugin will be used.
