UNEXPECTED_CHANNEL

Summary#

The network is advertised on a channel that is not in the list of configured expected channels. This could indicate that a possible attacker is not careful enough and does not limit spoofing to channels that are in use by the legitimate access points.

Almost all WiFi networks operate on 2.4 GHz or 5 GHz radio frequency ranges. Each range is divided into multiple channels to avoid overcrowding in environments that have many WiFi devices and access points present.

Possible False Positives#

  • A legitimate change of the access point configuration took place and the nzyme configuration has not been updated.
  • Some access points will dynamically choose channels based on RF spectrum congestion. Always include all possibly used channels in the nzyme configuration

Notes#

  • None
