/gobuster

Directory/File, DNS and VHost busting tool written in Go

Primary LanguageGoApache License 2.0Apache-2.0

Gobuster v3.1.0

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.
  • Open Amazon S3 buckets

Tags, Statuses, etc

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!

Changes in 3.1-dev

  • Use go 1.16
  • use contexts in the correct way
  • get rid of the wildcard flag (except in DNS mode)

Changes in 3.1

  • enumerate public AWS S3 buckets
  • fuzzing mode
  • specify HTTP method
  • added support for patterns. You can now specify a file containing patterns that are applied to every word, one by line. Every occurrence of the term {GOBUSTER} in it will be replaced with the current wordlist item. Please use with caution as this can cause increase the number of requests issued a lot.
  • The shorthand p flag which was assigned to proxy is now used by the pattern flag

Changes in 3.0

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

Available Modes

  • dir - the classic directory brute-forcing mode
  • dns - DNS subdomain brute-forcing mode
  • s3 - Enumerate open S3 buckets and look for existence and bucket listings
  • 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 install

If you have a Go environment ready to go (at least go 1.16), it's as easy as:

go install github.com/OJ/gobuster/v3@latest

PS: You need at least go 1.16.0 to compile gobuster.

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. You need at least go 1.16.0 to compile gobuster.

Compiling

gobuster has external dependencies, and so they need to be pulled in first:

go get && go build

This will create a gobuster binary for you. If you want to install it in the $GOPATH/bin folder you can run:

go install

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 folder.
  • make linux - builds 32 and 64 bit binaries for linux, and writes them to the build folder.
  • make darwin - builds 32 and 64 bit binaries for darwin, and writes them to the build folder.
  • make all - builds for all platforms and architectures, and writes the resulting binaries to the build folder.
  • make clean - clears out the build folder.
  • make test - runs the tests.

Wordlists via STDIN

Wordlists can be piped into gobuster via stdin by providing a - to the -w option:

hashcat -a 3 --stdout ?l | gobuster dir -u https://mysite.com -w -

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.

Patterns

You can supply pattern files that will be applied to every word from the wordlist. Just place the string {GOBUSTER} in it and this will be replaced with the word. This feature is also handy in s3 mode to pre- or postfix certain patterns.

Caution: Using a big pattern file can cause a lot of request as every pattern is applied to every word in the wordlist.

Example file

{GOBUSTER}Partial
{GOBUSTER}Service
PRE{GOBUSTER}POST
{GOBUSTER}-prod
{GOBUSTER}-dev

Examples

dir Mode

Command line might look like this:

gobuster dir -u https://mysite.com/path/to/folder -c 'session=123456' -t 50 -w common-files.txt -x .php,.html

Default options looks like this:

gobuster dir -u https://buffered.io -w ~/wordlists/shortlist.txt

Use case in combination with patterns

  • Create a custom wordlist for the target containing company names and so on
  • Create a pattern file to use for common bucket names.
curl -s --output - https://raw.githubusercontent.com/eth0izzle/bucket-stream/master/permutations/extended.txt | sed -s 's/%s/{GOBUSTER}/' > patterns.txt
  • Run gobuster with the custom input. Be sure to turn verbose mode on to see the bucket details
