Gobuster v3.0 - Directory/File, DNS And VHost Busting Tool Written In Go

| Post sponsored by FaradaySEC | Multiuser Pentest Environment

Gobuster is a tool used to brute-force:
  • URIs (directories and files) in web sites.
  • DNS subdomains (with wildcard support).
  • Virtual Host names on target web servers.

Oh dear God.. WHY!?
Because I wanted:
  1. ... something that didn't have a fat Java GUI (console FTW).
  2. ... to build something that just worked on the command line.
  3. ... something that did not do recursive brute force.
  4. ... something that allowed me to brute force folders and multiple extensions at once.
  5. ... something that compiled to native on multiple platforms.
  6. ... something that was faster than an interpreted script (such as Python).
  7. ... something that didn't require a runtime.
  8. ... use something that was good with concurrency (hence Go).
  9. ... to build something in Go that wasn't totally useless.

But it's shit! And your implementation sucks!
Yes, you're probably correct. Feel free to:
  • Not use it.
  • Show me how to do it better.

Love this tool? Back it!
If you're backing us already, you rock. If you're not, that's cool too! Want to back us? Become a backer!

All funds that are donated to this project will be donated to charity. A full log of charity donations will be available in this repository as they are processed.

Changes in 3.0
  • New CLI options so modes are strictly seperated (-m is now gone!)
  • Performance Optimizations and better connection handling
  • Ability to bruteforce vhost names
  • Option to supply custom HTTP headers

Available Modes
  • dir - the classic directory brute-forcing mode
  • dns - DNS subdomain brute-forcing mode
  • vhost - virtual host brute-forcing mode (not the same as DNS!)

Built-in Help
Help is built-in!
  • gobuster help - outputs the top-level help.
  • gobuster help <mode> - outputs the help specific to that mode.

Easy Installation

Binary Releases
We are now shipping binaries for each of the releases so that you don't even have to build them yourself! How wonderful is that!
If you're stupid enough to trust binaries that I've put together, you can download them from the releases page.

Using go get
If you have a Go environment ready to go, it's as easy as:
Usage:
  gobuster dns [flags]

Flags:
  -d, --domain string      The target domain
  -h, --help               help for dns
  -r, --resolver string    Use custom DNS server (format server.com or server.com:port)
  -c, --showcname          Show CNAME records (cannot be used with '-i' option)
  -i, --showips            Show IP addresses
      --timeout duration   DNS resolver timeout (default 1s)
      --wildcard           Force continued operation when wildcard found

Global Flags:
  -z, --noprogress        Don't display progress
  -o, --output string     Output file to write results to (defaults to stdout)
  -q, --quiet             Don't print the banner and other noise
  -t, --threads int       Number of concurrent threads (default 10)
      --delay duration    Time each thread waits between requests (e.g. 1500ms)
  -v, --verbose           Verbose output (errors)
  -w, --wordlist string   Path    to the wordlist

Building From Source
Since this tool is written in Go you need to install the Go language/compiler/etc. Full details of installation and set up can be found on the Go language website. Once installed you have two options.

Compiling
gobuster now has external dependencies, and so they need to be pulled in first:
Usage:
  gobuster dir [flags]

Flags:
  -f, --addslash                      Append / to each request
  -c, --cookies string                Cookies to use for the requests
  -e, --expanded                      Expanded mode, print full URLs
  -x, --extensions string             File extension(s) to search for
  -r, --followredirect                Follow redirects
  -H, --headers stringArray           Specify HTTP headers, -H 'Header1: val1' -H 'Header2: val2'
  -h, --help                          help for dir
  -l, --includelength                 Include the length of the body in the output
  -k, --insecuressl                   Skip SSL certificate verification
  -n, --nostatus                      Don't print status codes
  -P, --password string               Password for Basic Auth
  -p, --proxy string                  Proxy to use for requests [http(s)://host:port]
  -s, --statuscodes string               Positive status codes (will be overwritten with statuscodesblacklist if set) (default "200,204,301,302,307,401,403")
  -b, --statuscodesblacklist string   Negative status codes (will override statuscodes if set)
      --timeout duration              HTTP Timeout (default 10s)
  -u, --url string                    The target URL
  -a, --useragent string              Set the User-Agent string (default "gobuster/3.0.1")
  -U, --username string               Username for Basic Auth
      --wildcard                      Force continued operation when wildcard found

Global Flags:
  -z, --noprogress        Don't display progress
  -o, --output string     Output file to write results to (defaults to stdout)
  -q, --quiet             Don't print the banner and other noise
  -t, --threads int       Number of concurrent threads (default 10)
      --delay duration    Time each thread waits between requests (e.g. 1500ms)
  -v, --verbose              Verbose output (errors)
  -w, --wordlist string   Path to the wordlist
This will create a gobuster binary for you. If you want to install it in the $GOPATH/bin folder you can run:
Usage:
  gobuster vhost [flags]

Flags:
  -c, --cookies string        Cookies to use for the requests
  -r, --followredirect        Follow redirects
  -H, --headers stringArray   Specify HTTP headers, -H 'Header1: val1' -H 'Header2: val2'
  -h, --help                  help for vhost
  -k, --insecuressl           Skip SSL certificate verification
  -P, --password string       Password for Basic Auth
  -p, --proxy string          Proxy to use for requests [http(s)://host:port]
      --timeout duration      HTTP Timeout (default 10s)
  -u, --url string            The target URL
  -a, --useragent string      Set the User-Agent string (default "gobuster/3.0.1")
  -U, --username string       Username for Basic Auth

Global Flags:
  -z, --noprogress        Don't display progress
  -o, --output string     Output file to write results to (defaults to stdout)
  -q, --quiet             Don't print the ba   nner and other noise
  -t, --threads int       Number of concurrent threads (default 10)
      --delay duration    Time each thread waits between requests (e.g. 1500ms)
  -v, --verbose           Verbose output (errors)
  -w, --wordlist string   Path to the wordlist
If you have all the dependencies already, you can make use of the build scripts:
  • make - builds for the current Go configuration (ie. runs go build).
  • make windows - builds 32 and 64 bit binaries for windows, and writes them to the build subfolder.
  • make linux - builds 32 and 64 bit binaries for linux, and writes them to the build subfolder.
  • make darwin - builds 32 and 64 bit binaries for darwin, and writes them to the build subfolder.
  • make all - builds for all platforms and architectures, and writes the resulting binaries to the build subfolder.
  • make clean - clears out the build subfolder.
  • make test - runs the tests.

Wordlists via STDIN
Wordlists can be piped into gobuster via stdin by providing a - to the -w option:
go get github.com/OJ/gobuster
Note: If the -w option is specified at the same time as piping from STDIN, an error will be shown and the program will terminate.

Examples

dir Mode
Command line might look like this:
go get && go build
Default options looks like this:
go install
Default options with status codes disabled looks like this:
hashcat -a 3 --stdout ?l | gobuster dir -u https://mysite.com -w -
Verbose output looks like this:
gobuster dir -u https://mysite.com/path/to/folder -c 'session=123456' -t 50 -w common-files.txt -x .php,.html
Example showing content length:
gobuster dir -u https://buffered.io -w ~/wordlists/shortlist.txt
