FalsePositives within Kahoot PinBruteforcer

[mLoDar]

Currently there are some issues with the PinBruteforcer module.
When generating new Kahoot game pin to check, it will be checked by reserving a session.

If a session could not be reserved the pin is invalid.
If a session could be reserved, the module automatically flags the pin as valid and prints it to the console.

The current problem:

As it shows in the picture above, when joining with the pin and submitting a username, Kahoot tells us that the game has already ended.
I am not sure why it does that or what kind of pins they are.

Possible solutions:

• Check via a WebDriver (Selenium) if a game can be joined, if the session reservation is valid.
• Find some other way, to tell if the game has ended by using a WebSocket.
