What is the default login for BeEF?

By default, beef/beef is the login. Check out the documentation.

How do I configure integration with Metasploit?

Be sure to read the documentation (and here also), and take care especially of the following points :

  • Enable MSF integration by changing beef.extension.metasploit.enable to true in BeEF's main config.yaml file.
  • Ensure you load the msgrpc interface in Metasploit before starting BeEF: msf > load msgrpc ServerHost= Pass=abc123 SSL=y
  • Ensure that the IP address supplied to Metasploit with the ServerHost parameter is the same IP address as specified in
  • Ensure that the IP address specified in beef.extension.metasploit.callback_host is the publicly accessible IP address for victim connections to Metasploit.
  • Ensure that if SSL=y was supplied to Metasploit when starting msgrpc then beef.extension.metasploit.ssl is set to true.

How do I configure BeEF on a server behind NAT?

  • Ensure beef.http.public and beef.http.public_port are set to the public WAN IP address and public WAN port respectively.
  • Forward the public port (default 3000/tcp) from your border router to <LAN IP>:3000 of the BeEF server.
  • Additionally, ports 61985/tcp and 61986/tcp must also be forwarded if web sockets are enabled for communicating with BeEF.
  • Likewise, some BeEF extensions, such as IPEC and DNS, require additional ports to be forwarded. Review the associated config.yaml file for each extension and ensure the appropriate ports are forwarded.

How do I configure BeEF with ngrok?

Download ngrok, then tunnel your BeEF port (default: 3000):

$ ngrok http 3000

Specify the public domain name beef.http.public and public port beef.http.public_port in config.yaml:

        public: "<your-id>"      # public hostname/IP address
        public_port: "80"                 # public port (experimental) 

Can I use a domain name instead of IP address for the BeEF hook?

Yes! Simply specify the public domain name and port in beef.http.public and beef.http.public_port respectively in config.yaml.

How do I fix ArgumentError - invalid byte sequence in US-ASCII ?

Set the appropriate locale:

export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8
export LC_ALL=en_US.UTF-8

Why does BeeF update fail?

If you're getting the error Your local changes to the following files would be overwritten by merge: Gemfile.lock it means BeEF's dependencies were recently updated.

To fix, run git checkout Gemfile.lock, then update BeEF and run bundle install to install the updated packages.
