i dont know if this is approved to be here, so i'll post it and will see what you guys think of it...
i'm going to explain in this tutorial how to access wireless networks even though they might have a WEP code on them.
i have not realized before that it could be that easy of a task, but i have found three programs till now that can do the job right.

the first program is calle Airsnort. this program is like a tool that cracks WEP encryption codes or keys. what it does is it monitors the transmissions and then calculates the encryption key when it has gathered enough packets.

for those who dont know what WEP means, WEP stands for Wired Equivalent Privacy. this is the encryption algorithm built into the 802.11 (Wi-Fi).

the second program is a package called bsd-airtools, it currently contains a bsd-based (WEP) cracking application. It also contains a curses based ap detection application that can be used to detect wireless access points and connected nodes, view signal to noise graphs, and interactively scroll through scanned ap's and view statistics for each. it's probably harder to use than Airsnort since it has multiple applications.

the third one is my favorite, it's called wepattack and it's a WLAN open source Linux tool for breaking 802.11 Wired Equivalent Privacy keys. This tool is based on an active dictionary attack that tests millions of words to find the right key. Only one packet is required to start an attack on WEP.

download them and try..hope this tutorial was useful.

The Airsnort osunds the best one out of the rest. A dictionary attack takes a long time and doesnt allways give good results. I have heard of many people who recomend AirSnort.

Not really much of a tutorial if you dont mine me saying

Teaches something at least. So, useful for those (like me) who don't know how to do these things.

In some countrys it's illegal to break the WEP encryption, doesn't matter what way you use. But yeah, these are some really handy ways to get WEP keys from your neighbours.

But still, what'd you want to do with them? >_<. I think hacking unprotected networks is kinda pathetic.

Does this work with WI-Fi nettworks too?

WI-Fi and "Wireless Networks" are two different ways for saying the same thing : a network without cables, with a very precise protocol, which is embedded in most of recent laptops for example.
If your main home router has no WEP encryption your network is exposed to anybody having no knowledge.
The present topic explains that even if your network is WEP-protected, you may experience intrusions.

Doesn't windows come with this????

Windoze doesn't protect you, let alone get pass other people's protection. Wifi is network connections.

When I added wireless on my dads computer, we found one open, ours and one locked (Bt home hub is really common, most of the country got it free) but I havn't got a card to try this.

The place I'm living in have a lot of wireless network protected and they are always on. Just thought of trying out the program you've mention and see whether it will work. Anyway its illegal here in my country and seems that now I hardly find any wireless network without WEP encryption. Seems that people get abit more technical here.

Anyway nice post. Cheers

Not if you're surrounded by Wi-Fi networks, all waiting for you to jump in undetected (mostly).

Think of it as a sort of free hosting.
