9, *** the harm to the network after the key case of (fake AP)
Once the intruder knows the WEP or WPA wireless network key, you can connect to the local LAN, so intruders to enjoy As with normal access to the user access rights to the entire network, in-depth attack. Intruders can use IPBOOK, SuperScan tool like this and other LAN scanning the computer, the computer inside the files, directories, or entire hard drive can be copied or deleted, or even worse, other cases such as keyloggers,[link widoczny dla zalogowanych], Trojan horses, spyware, program or other malicious programs, and so can be installed on your system,[link widoczny dla zalogowanych], so the consequences are very serious.
(1) Introduction to WEP or WPA password when
been ***, the intruder may use the password and other wireless access point (AP) constructed a fake network, the signal strength when the camouflage of normal AP AP AP camouflage or user close to, the normal user will naturally leave access to the network, the user is in itself not feel the network to send and receive messages in the normal user, we can use similar tools such CAIN for POP3, telnet, etc., etc. *** password attacks.
(2) POP3 password ***
1) Open CAIN.
2) Click on the menu bar \
3) select a network adapter will be used for packet capture, click \
4) normal user starts the mail, the software can mail login name and password capture.
(3) the harm after being ***
when hackers your mailbox user name, password, POP3 server and SMTP server's IP address , you can directly access your mailbox, your e-mail information will be fully exposed to the hackers before.
Our purpose of this experiment is to capture the appropriate data through the frame IV (initialization vector) Violence *** get WEP KEY, it only need to use airodump.exe (used to capture data frame) and WinAircrack.exe ( *** WEP KEY with) two programs on it

4, configure the wireless router (based on the actual network environment to configure)
(1) STA1 connected to the wireless router (the default is not encrypted.) Right-click the icon below the screen, select \
which shows a number of available wireless networks, double-click the TP-LINK wireless router connected, while on the connection is successful.
(2) Open the IE browser, enter the IP address: 192.168.1.1 ( wireless router default LAN IP address).
(3) wireless router management interface login (user name: admin, password: admin).
