Garrett: Wifi deauthentication attacks and home security
Matthew Garrett works
out how to avoid being recorded by "Ring" door cameras in his apartment
building. "The most interesting one here is the deauthentication
frame that access points can use to tell clients that they're no longer
welcome. These can be sent for a variety of reasons, including resource
exhaustion or authentication failure. And, by default, they're entirely
unprotected. Anyone can inject such a frame into your network and cause
clients to believe they're no longer authorised to use the network, at
which point they'll have to go through a new authentication cycle - and
while they're doing that, they're not able to send any other
packets."
