This document discusses wireless network security. It begins by outlining the basics of wireless LANs including operating frequencies, channels, and SSIDs. It then describes several common wireless attacks such as obtaining hidden SSIDs, bypassing MAC filters, evil twin attacks, and cracking WEP/WPA encryption. Finally, it provides tips for securing a wireless network, including using WPA2 encryption with a strong password, enabling the router's firewall, and reducing the WiFi range.

3. Basics of WLAN
• WLAN can operate in 3 different frequency
range. (2.4 GHZ, 3.6 GHZ, 5.0 GHZ)
• Each of these is divided into multiple
channels.
• Every access point is configured with an
SSID.

4. • The SSID acts as a network name for
discovery.
• AP sends out broadcast frames called
beacon frames to announce it’s presence.
• WLAN headers are not encrypted – that’s
something to worry about.

5. Wireless Attacks
Getting Hidden SSID’s name`
Bypassing MAC filters
Evil twin and MiTM attack
Hacking Isolated clients
WEP/WPA cracking

6. Getting Hidden SSID’s name
• Network name is not broadcasted over the
air when SSID broadcasting is turned off
• Association and authentication packets
contain SSID value.
• If we monitor an authentication request,
we could get the SSID value.

7. Bypassing MAC filters
• We can easily monitor the authorized
clients connected to the AP.
• All we need to do is to clone that MAC
address.

8. Evil Twin Attack

victimSSID: Pwned
Internet
Attacker
SSID: Pwned
Deauth Attack

9. Hacking Isolated clients
• Client send probe requests periodically to
previously connected clients.
• If the clients finds an open network with
the same SSID, the client would
automatically connect with it.
• It depends on the OS behavior.

10. Cracking WEP/WPA
• WEP can be very easily cracked.
• WPA/WPA2 can be also be cracked if the
password is weak.
• WPS pin bruteforcing.
• Router vulnerabilities.

12. Why you need to worry?
• Attackers can use your wifi network to
commit dangerous cyber crimes.
• Hacker’s can access your personal
information, steal sensitive data, plant a
backdoor, etc.

14. How to secure your wireless network
• Never use WEP!
• Use WPA2 with strong password.
• Turn the router’s firewall on.
• Change the router’s default password.
• Never depend on techniques like MAC
filtering or Hidden SSID.
• Reduce the range of wifi.
• Never connect to unknown and open wifi
networks.
• Use a good antivirus and firewall.
