Wireless WEP Key Password Spy 1.1
 

http://i33.tinypic.com/2wdabo5.jpg

This software will instantly recover all WEP keys and wireless network passwords that have been stored on your computer.
To get started, click “Find Wireless WEP Keys”. It will then display the adapter GUID and all
recovered information associated with it including the wireless network name (SSID), the encryption type (WEP 40,
WEP 104, or WPA-PSK), and the WEP key associated with each network. At the bottom of the screen you can see the
name of your current Ethernet adapter, the total Kb sent and received during the current Windows session, and the
current down/up throughput.

Thank you but NirSoft.net has a free, guaranteed malware-free solution for this problem, too. [...] And I'm not so sure your software is free of malware: it looks like some trojan stealing DynDNS.org account data.

Yes this soft can be considered trojan but all programs like this one using the same system to recover some things from your pc and antivirus consider him a virus.. like keygen too. Anyway thanks for the sharing... this is what i wanted to find.

Besides I dont think its prudent to let this sort of thing on the forum, its obviously a tool so people can leech from other networks without paying for an ISP.

If people are unsure that their networks are safe even with WEP/WPA keys, in the router settings most routers will have an extra options of allowing specified MAC addresses.
