Hi Folks,

I've found an anonymity threat in Freenet which concerns me.

I had gathered that Fproxy screens incoming HTML from Freenet and warns users 
about any matter which can threaten their privacy.

But I inserted a web page into Freenet which uses a '<IMG' tag to pull in the 
'hops' graphic from the Freenet site.
I loaded this page, and Fproxy was none the wiser.
Try it for yourself -
freenet:KSK at privacy-threat
or http://127.0.0.1:8081/privacy-threat

Why it worries me is that it's easy to insert html pages into Freenet that 
contain 'web bugs' - small 1x1 clear GIF images sourced from a mainstream web 
server. Loading such Freenet pages via fproxy will result in one's browser 
automatically sending a hit to an actual web server, which is a total loss of 
privacy.

Unless fproxy is reworked to handle this, the only defence I can think of is to 
set one's firewall temporarily to block the browser's access to external 
servers while surfing Freenet.

David
