Hi guys

Thanks for quick responces

could you possibly explain a few concepts about chopchop to me then please?

as i have read it here: (along with this forum)

I have come to understand that chopchop decrypt's a WEP data packet without discovering the WEP key, so it reveles the keystream / PRGA to that packet.

that keystream can then be forged to other packets, these are then injected to the AP to force the AP to re-encrypt the packet and generate traffic

please correct me where im wrong.

regards
Kai
