# 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

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

## 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](https://github.com/OJ/gobuster/releases) page.
### Using `go install`
If you have a [Go](https://golang.org/) environment ready to go (at least go 1.16), it's as easy as:
```bash
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](https://golang.org/) you need to install the Go language/compiler/etc. Full details of installation and set up can be found [on the Go language website](https://golang.org/doc/install). 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:
```bash
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:
```bash
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:
```bash
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
```text
{GOBUSTER}Partial
{GOBUSTER}Service
PRE{GOBUSTER}POST
{GOBUSTER}-prod
{GOBUSTER}-dev
```
## Examples
### `dir` Mode
Command line might look like this:
```bash
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:
```bash
gobuster dir -u https://buffered.io -w ~/wordlists/shortlist.txt

### `fuzzing` Mode
Command line might look like this:

```
#### 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.
```bash
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
```bash
gobuster s3 --wordlist my.custom.wordlist -p patterns.txt -v
```
Normal sample run goes like this:
