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.

When you've learned to do the following :
1) Read the Forum rules and guidelines (ALL of them) as posted in the Welcome Desk Section, and adhere to those rules and guidelines in your posts on the forums.
2) Retaken Reading & Comprehension 101 class.
3) Actually read and understood the thread you are posting in.

Then, and ONLY then you might have a chance of understanding something about how the KoreK attack works, and how his ChopChop tool functions. Untill you have done the 3 items outlined above, you should refrain from posting anything on the subject of breaking wep encryption.

Disregard the advice given to you in this post at your own peril.

Oh and in case you haven't heard it yet :
Cracking WEP is SO yester-year!!
WEP is insecure, it's a fact, proven long time ago! No need to crack it. Use WPA or other measures, even if it means you need to upgrade equipment.

This thread is hereby officially closed, and can only be opened on request from KoreK if he feels there is something new to report.
