Most wireless hacking attacks can be categorized as follows:

Cracking Encryption and Authentication Mechanisms. These mechanisms include cracking WEP, WPA preshared key authentication passphrases, and Cisco’s Lightweight EAP authentication (LEAP). Hackers can use these mechanisms to connect to the WLAN using stolen credentials or can capture other users’ data and decrypt or encrypt it. A protection against this attack is to implement a stronger type of encryption, such as AES.

Eavesdropping or Sniffing. This type of attack involves capturing passwords or other confidential information from an unencrypted WLAN or hotspot. A protection against this attack is to use SSL application-layer encryption or a VPN to secure user data.

Denial of Service. DoS can be performed at the physical layer by creating a louder RF signature than the AP with an RF transmitter, causing an approved AP to fail so users connect to a rogue AP. DoS can be performed at the Logical Link Control (LLC) layer by generating deauthentication frames (deauth attacks), by continuously generating bogus frames, or by having a wireless NIC send a constant stream of raw RF (Queensland attack). A countermeasure is to enforce a security perimeter around your WLAN and detect and remove sources of DoS attacks using an IDS.

AP Masquerading or Spoofing Rogue. APs pretend to be legitimate APs by using the same configuration SSID settings or network name. A countermeasure to AP masquerading is to use a WIDS to detect and locate spoofed APs.

MAC Spoofing. The hacker pretends to be a legitimate WLAN client and bypasses MAC filters by spoofing another user’s MAC address. WIDSs can detect MAC spoofing, and not using MAC filtering is a way to avoid MAC spoofing attacks.

Planting Rogue Access Points. The most dangerous attack is a rogue AP that has been planted to allow a hacker access to the target LAN. A countermeasure is to use a WIPS to detect and locate rogue APs.

Wireless networks give a hacker an easy way into the network if the AP isn’t secured properly. There are many ways to hack or exploit the vulnerabilities of a WLAN. There are also effective countermeasures to many of these attacks.
