Note: SniffJoke project at the moment need a complete redesign and can't be considered stable, outside a laboratory testing environment -- Feb 2013
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!
Layer 3 tricks to impair traffic analysis.
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.
