Submit Issue

Verify first that your issue/request has not been posted previously:

• https://github.com/beefproject/beef/issues
• https://github.com/beefproject/beef/wiki/FAQ

Ensure you're using the latest version of BeEF.

Please do your best to provide as much information as possible. It will help substantially if you can enable and provide debugging logs with your issue. Instructions for enabling debugging logs are below:

1. In the config.yaml file of your BeEF root folder set debug and client_debug (lines 11 & 13 respectively) to true
   • If using a standard installation of beef-xss the root folder will typically be /usr/share/beef-xss
2. Reproduce your error
3. Retrieve your client-side logs from your browser's developer console (Ctrl + Shift + I)
4. Retrieve your server-side logs from ~/.beef/beef.log
5. If using beef-xss: Retrieve your service logs using journalctl -u beef-xss

Thank you, this will greatly aid us in identifying the root cause of your issue :)

If we request additional information and we don't hear back from you within a week, we will be closing the ticket off. Feel free to open it back up if you continue to have issues.

latest beef version

[bcoles]

The config file is in YAML format. Whitespace is important.

The dns key is not vertically aligned correctly.

[bcoles]

Also, as far as I'm aware, the dns key does nothing. I have no idea why it is in your config file.

[catchmeifyoucaan]

thank u so much, i just corrected that and got this little error now [23:13:32][!] Warning: System language $LANG '' does not appear to be UTF-8 compatible.
Traceback (most recent call last):
./beef:119:in <main>': undefined methodvalidate' for BeEF::Core::Configuration:Class (NoMethodError)

[catchmeifyoucaan]

okay, ill remove the dns key now

[catchmeifyoucaan]

thank i remove the dns key but the error is still there [23:15:42][!] Warning: System language $LANG '' does not appear to be UTF-8 compatible. Traceback (most recent call last): ./beef:119:in <main>': undefined methodvalidate' for BeEF::Core::Configuration:Class (NoMethodError)

[bcoles]

./beef:119:in

': undefined method validate' for BeEF::Core::Configuration:Class (NoMethodError)

Strange. There's no immediately obvious reason why this would fail.

You could try removing these lines from beef, but that will likely be hiding another bug.

https://github.com/beefproject/beef/blob/5fdd96f5761dfd0bfe36b9e24ab390c29194e349/beef#L116-L121

[catchmeifyoucaan]

sorry, but i dont see anything like this in config.yaml, where should i make the changes, under what configuration

[bcoles]

sorry, but i dont see anything like this in config.yaml, where should i make the changes, under what configuration

It's code in the beef file.

[catchmeifyoucaan]

after i deleted those lines, it shows this again Traceback (most recent call last): 4: from ./beef:119:in <main>' 3: from /home/surprise/beef/core/main/configuration.rb:201:inget' 2: from /home/surprise/beef/core/main/configuration.rb:201:in inject' 1: from /home/surprise/beef/core/main/configuration.rb:201:ineach' /home/surprise/beef/core/main/configuration.rb:202:in block in get': undefined method[]' for nil:NilClass (NoMethodError)

[bcoles]

after i deleted those lines, it shows this again

Have you made any other changes to the config file apart from removing the dns key?

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. Have you modified any of the config.yaml files in any of the extensions?

i made little changes to this configuration.rb too. please check them out, beef has been delaying my study for quite a while now

[catchmeifyoucaan]

I'm counting on you @bcoles

[bcoles]

Please use triple backticks to format code. It makes the code much easier to read.

no, i have not made any changes after i deleted the dns, and i added it from a tutorial i saw on youtube when the hook link wasnt working, beef was working fine before all of this, just the hook. pleaswe

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.

i made little changes to this configuration.rb too. please check them out, beef has been delaying my study for quite a while now

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.

[bcoles]

no, i have not made any changes after i deleted the dns, and i added it from a tutorial i saw on youtube when the hook link wasnt working, beef was working fine before all of this, just the hook. pleaswe

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/false

That is incorrect. The host property expects a host not a URL.

        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

[catchmeifyoucaan]

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

[bcoles]

whats supposed to be in the host space?

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 configuration.rb file - suspiciously the exact file where you're getting errors - based on what some random person said in some random youtube video.

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.

[catchmeifyoucaan]

i made changes to @@instance because it doesnt have a value so i made it @@instance = self, that was the only changes i made to the configuration file. triple back ticks you mean '''?

[bcoles]

if you would be here to help, i'll do it now

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.

i made changes to @https://github.com/instance because it doesnt have a value so i made it @https://github.com/instance = self

That... doesn't sound right.

triple back ticks you mean '''?

beef configuration, complete

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:

git diff ./beef

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.

I'm pretty sure you can't have a space between a variable and the array element.

In fact none of these changes make sense. I suggest reverting them all.

[catchmeifyoucaan]

thank you for yur help, but i really dont understand this, yes i want beef to work and its not, ill 100% follow what u say, even if i have to purge everything and start again

[bcoles]

I'm on the phone and will be for a while. I'll be back in a while. I suggest making a backup then create a new fresh clone.

[catchmeifyoucaan]

wow, so i should remove the ones marked in red lines and replace wth the green ones? thanks ill do that now

[catchmeifyoucaan]

I'm on the phone and will be for a while. I'll be back in a while. I suggest making a backup then create a new fresh clone.

okay, yes i use beef from github, i think ill delete everything and start again, becaue when you used diff, i didnt change that much code and i dont if it means to change from the green lines to the red lines or vice versa

[bcoles]

It's possible that your version of BeEF is old. A couple of those changed lines were introduced a few days ago.

[catchmeifyoucaan]

okay @bcoles, thank you all along, so do you suggest i make the chnages myself in nano, or just redownload everything. and if i have to change the code, the red colored lines are the now correct codes, right?

[bcoles]

okay @bcoles, thank you all along, so do you suggest i make the chnages myself in nano, or just redownload everything. and if i have to change the code, the red colored lines are the now correct codes, right?

No. Stop breaking things.

I suggest making a backup then create a new fresh clone.

[catchmeifyoucaan]

okay, thank u, i dont understand making a fresh clone tho because while i try git clone at the beef folder, it says it already exist and i cant clone it because its not empty. and i dont know how to upgrade to the latest, so i will just purge out beef and start all over again, ill sure get back to you in few minutes please dont close this session.

[bcoles]

i dont understand making a fresh clone tho because while i try git clone at the beef folder,

mkdir /tmp/broken
mv beef /tmp/broken
git clone https://github.com/beefproject/beef

[catchmeifyoucaan]

appreciate you, im cloning it now inside the main beef folder, i'll let you know when its done

[catchmeifyoucaan]

thank you so much, @bcoles i can now log back in my beef, but i have few questions/errors

the code is way more than this, i cant paste all here, to reproduce, just use the hook url in chromium, that was why i wanted to use it with ngrok and did all the meaningless changes, please help now since we here

One thing at a time.

BeEF works now, correct?

You were able to hook a browser using the demo page, correct?

[bcoles]

the code is way more than this, i cant paste all here, to reproduce, just use the hook url in chromium,

That is the BeEF hook JavaScript code. It won't execute by itself. Try the demo page.

[catchmeifyoucaan]

yes demo page works fine, but thats the code it shows for the main hook url, how can i execute it if it shows that in a suppose target browser, the demo page is good tho, but i think i need the url to work, please
