When attempting to break into a wireless network, attackers often need to gather multiple authentication attempts which can take time. In this video, Mike Chapple explains how attackers can speed up this process by tricking wireless clients into reauthenticating via disassociation attacks. This technique may also be used to conduct a wireless denial of service attack.
- Many attacks against wireless encryption…require that the attacker collect a large number…of authentication attempts from wireless clients.…Disassociation attacks speed up this time-consuming process.…They may also be used in denial of service attacks…against wireless network.…In an earlier video, I described how attacks…against WEP and WPA require the attacker to collect…information from a large number of wireless…client authentication attempts.…Normally, once a client connects to a network,…it continues to use that wireless network…for an extended period of time without re-authenticating.…
For example, a client might re-authenticate…only once or twice every hour.…On a low-traffic network, this means that it can take…quite a bit of time before an attacker is able…to gather enough information to conduct an attack.…The WiFi standard provides access points with the means…to immediately disconnect devices from the network.…This is often used when the network…detects a rogue network connection.…The access point sends a special frame,…
