does anyone have any knowledge regarding replacing .exe file request on a broadcast network by exploiting a race condition... from what i understand at the moment one can sniff network traffic and on finding the "content-type:application" as a request respond to it with his own binary file,,, i think this would be even more cool than using ettercap filters and injecting code on the fly into an html page....

if this is possible it can also lead to a whole new kind of injection attack in 802.11 network where an attacker can send data to the victim with out even being associated to the AP.
