<impact type="normal">
|
|
|
|
|
|
<p>An attacker can carry out the KRACK attacks on a wireless network in
|
|
|
|
|
|
order to gain access to network clients. Once achieved, the attacker can
|
|
|
|
|
|
potentially harvest confidential information (e.g. HTTP/HTTPS), inject
|
|
|
|
|
|
malware, or perform a myriad of other attacks.
