Frequently Asked Questions¶
Can we somehow bypass the SSL warning displayed by the browsers?¶
By default, Wifiphisher will try to imitate the behavior of a public hotspot. Redirection to a captive portal served over HTTPS with a self-signed certificate is what a user will typically experience when connecting to a captive portal.
If, however, one wants to use Wifiphisher to obtain a man-in-the-middle position and effectively bypass HSTS / HTTPS, it is recommended to use Wifiphisher in conjuction with other security tools. For example, a user can run Wifiphisher and provide the victims with Internet (using the -iI option) and at the same time leverage the Evilginx project using a valid domain and a valid SSL certificate.
Why some victim users do not automatically connect to the rogue Access Point?¶
A successful automatic association attack relies on many different factors including:
- Victim’s Network Manager. Different Operating Systems support different wireless features. For example, an Android device will, by default, connect automatically to previously connected open networks making it susceptible to the Known Beacons Wi-Fi automatic association attack. At the same time iOS devices are configured to arbitrarily trasmit probe request frames for previously connected networks making them vulnerable to the KARMA attack.
- Victim’s Preferred Network List. KARMA and Known Beacons attacks heavily rely on the victim’s Preferred Network List. The number of open “trusted” networks in the victim’s PNL will significantly raise the chances for a succesfull attack. On the other hand, if the Preferred Network List is empty, these attacks are doomed to fail.
Why does deauthentication is not always working?¶
The two most common reasons are:
- You are physically too far away from the victim clients. You need enough transmit power for the packets to be heard by the clients.
- The wireless card used for the deauthentication attack operates in a different mode than the victim’s card, hence the client is not able to receive the frames.
