Hi, it's not easy Open Bullet however now you have to download a "config" for your purpose, in this case for a brute force attack with user : password to search m3u lists.
You will need to get or find a "dictionary" (combo) with username : password.
Once you have these two things you need to put them in the program directories: the downloaded "config" in Config and the combos in Wordlists.
Also check the "Environment.ini" file located in the program directory, in the "Settings" folder... open the "Environment.ini" file
e vedi se hai l'esempio "[WLTYPE]" corretto:
[WLTYPE]
Name=Credentials
Regex=^.*:.*$
Verify=True
Separator=:
Slices=USERNAME,PASSWORD
Some unofficial O.B releases tend to put nothing (blank file)
It could be that the config you download in the initial part (you have to open the config with notepad) under "AllowedWordlist1": does not say: Credentials as in the Environment file but for example: "userpass" you will have to change the name by writing what is there is under "AllowedWordlist1":
You still have to try, maybe everything coincides.
Open O.B. go to the top menu "Runner" press +New, now move the mouse to config in the new menus that have opened click on it and load the Config... then always go to Wordlist and load the combos...then always there go to Bots and put the number of bots (if you don't have proxies keep the number low (3/5)... then always switch them to proxies (put off to start, when you are no longer a beginner you can play with proxies)
then always click on Status (in yellow).
Now press Start at the top right, a window should appear where you will enter the url you want to attack... Accept
In all of this I am referring to Open Bullet 1, however I advise you to start with a pre-configured tool where you will insert a few things.
Regards.
