crash other machines using UDP flooders..

crash other machines using UDP flooders..
windows OS has an outstanding packet limit......
packets are data packs that constitute the internet traffic......
if the no of packets recieved at a time exceeds a particular limit, the operating system crashes..
standard package limit for windows and contemporary operating systems is 65535....
normal internet traffic does not constitute more than 600 packets at a time unless bandwidth is exceptionally high........
however if more than 65535 packets could be sent at a time the target pc crashes at once..this process is called UDP flooding (udp being user data protocols)..........
systems upto win '98 are vulnerable to these kind of attacks by default.........but the higher versions of windows have a built in packet limiter as a protection against UDP flooding.


Inorder to crash a victims pc all u need to do is to gain access to the pc and change the outstanding package limit to a number greater than 65535.........

steps to access the package console.......
in case of win xp..............
1. type gpedit.msc in run...
2. on the left menu double click administrative templates.
3. network==> qos package scheduler==> limit outstanding packets..

double click on limit outstanding packets and choose enable.........this displays the default packet limit.........reedit it to a value much higher than the original one.......this done u r ready to attack....
