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
Because I wanted:
- ... something that didn't have a fat Java GUI (console FTW).
- ... to build something that just worked on the command line.
- ... something that did not do recursive brute force.
- ... something that allowed me to brute force folders and multiple extensions at once.
- ... something that compiled to native on multiple platforms.
- ... something that was faster than an interpreted script (such as Python).
- ... something that didn't require a runtime.
- ... use something that was good with concurrency (hence Go).
- ... to build something in Go that wasn't totally useless.
Yes, you're probably correct. Feel free to:
- Not use it.
- Show me how to do it better.
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.
- 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
- 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
- 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!)
Help is built-in!
gobuster help
- outputs the top-level help.gobuster help <mode>
- outputs the help specific to that mode.

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.
If you have a Go environment ready to go, it's as easy as:
go get github.com/OJ/gobuster
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.
gobuster
now 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. runsgo build
).make windows
- builds 32 and 64 bit binaries for windows, and writes them to thebuild
folder.make linux
- builds 32 and 64 bit binaries for linux, and writes them to thebuild
folder.make darwin
- builds 32 and 64 bit binaries for darwin, and writes them to thebuild
folder.make all
- builds for all platforms and architectures, and writes the resulting binaries to thebuild
folder.make clean
- clears out thebuild
folder.make test
- runs the tests.
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.
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.
{GOBUSTER}Partial
{GOBUSTER}Service
PRE{GOBUSTER}POST
{GOBUSTER}-prod
{GOBUSTER}-dev
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
