wireless attacks

Wireless deauthentatication

Wireless dos attack that glitches

802 management frames

Frames that make everything work and we don't see them

Used to connect, manage disconnect networks

How are management frames used in attacks

Earlier versions didn't have any security with no encryption so attackers could manipulate these frames

How to protect against deauth attacks

Updates 802.11 and encrypted deauthentatication, disassociate, channel switch announcements

What is not encrypted in 802.11ac and why

Beacons, probes, authentication, association frames

There are many management frames that have to be in the clear prior to encryption

Radio frequency (rf) jamming

Dos attack that affects everyone communicating over wireless frequency

Attackers transmit interfering wireless signals to anyone nearby

Receiving device can't hear the signal

Is rf jamming common and why

Yes it can be unintentional like when you use your microwave

Types of wireless jamming

Attackers can send constant random bits of info or they can send large legit frames

May send data at random times

Reactive jamming that happened only when someone tries to communicate on the network

The location of wireless jamming problems

Nearby

Fox hunt

Locating person causing the jamming
