Gobuster

Gobuster is a tool used to brute-force:

• URIs (directories and files) in websites.
• DNS subdomains (with wildcard support).
• Virtual Host names on target web servers.
• Open Amazon S3 buckets
• Open Google Cloud buckets
• TFTP servers

Tags, Statuses, etc

Changes

3.7

3.7

• use new cli library
• a lot more short options due to the new cli library
• more user friendly error messages
• clean up DNS mode
• renamed show-cname to check-cname in dns mode
• got rid of verbose flag and introduced debug instead
• the version command now also shows some build variables for more info
• switched to another pkcs12 library to support p12s generated with openssl3 that use SHA256 HMAC
• comments in wordlists (strings starting with #) are no longer ignored
• warn in vhost mode if the --append-domain switch might have been forgotten
• allow to exclude status code and length in vhost mode
• added automaxprocs for use in docker with cpu limits
• log http requests with debug enabled
• allow fuzzing of Host header in fuzz mode
• automatically disable progress output when output is redirected
• fix extra special characters when run with --no-progress
• warn when using vhost mode with a proxy and http based urls as this might not work as expected
• add interface and local-ip parameters to specify the outgoing interface for http requests
• add support for tls renegotiation
• fix progress with patterns by @acammack
• fix backup discovery by @acammack
• support tcp protocol on dns servers
• add support for URL query parameters

3.6

3.6

• Wordlist offset parameter to skip x lines from the wordlist
• prevent double slashes when building up an url in dir mode
• allow for multiple values and ranges on --exclude-length
• no-fqdn parameter on dns bruteforce to disable the use of the systems search domains. This should speed up the run if you have configured some search domains. https://github.com/OJ/gobuster/pull/418

3.5

3.5

• Allow Ranges in status code and status code blacklist. Example: 200,300-305,404

• 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

3.0

3.0

• Performance Optimizations and better connection handling
• Ability to enumerate vhost names
• Option to supply custom HTTP headers

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.

Docker

You can also grab a prebuilt docker image from https://github.com/OJ/gobuster/pkgs/container/gobuster

docker pull ghcr.io/oj/gobuster:latest

Using go install

If you have a Go environment ready to go, it's as easy as:

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

PS: You need at least go 1.24 to compile gobuster.

Complete manual install steps

• Remove possible golang packages from your package distribution (eg apt remove golang)
• Download the latest golang source from https://go.dev/dl
• Install according to https://go.dev/doc/install (don't forget to add it to your PATH)
• Set your GOPATH environment variable export GOPATH=$HOME/go
• Add $HOME/go/bin to your PATH variable (go install will install to this location)
• Make sure all environment variables are persisted across your terminals and survive a reboot
• Verify go version shows the downloaded version and works
• go install github.com/OJ/gobuster/v3@latest
• verify you can run 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.

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

Modes

Help is built-in!

• gobuster help - outputs the top-level help.
• gobuster help <mode> - outputs the help specific to that mode.

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
• gcs - Enumerate open google cloud buckets
• vhost - virtual host brute-forcing mode (not the same as DNS!)
• fuzz - some basic fuzzing, replaces the FUZZ keyword
• tftp - bruteforce tftp files

dns Mode

DNS mode allows you to bruteforce subdomains of a given domain. If the subdomain has a DNS record, it will be printed out.

Examples

gobuster dns -d mysite.com -t 50 -w common-names.txt

Normal sample run goes like this:

gobuster dns --do google.com -w ~/code/SecLists/Discovery/DNS/subdomains-top1million-5000.txt

dir Mode

In DIR mode you can enumerate all directories and/or files on a given url. If you specify file extension files are also enumerated.

Examples

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

vhost Mode

VHOST mode requests the site over and over and enumerates all values of the Host header. This allows finding custom virtual hosts on the same ip.

Examples

gobuster vhost -u https://mysite.com -w common-vhosts.txt

gobuster vhost -u https://mysite.com -w common-vhosts.txt

fuzz Mode

FUZZ mode allows you to do some manual fuzzing. Each value of {GOBUSTER} inside the request will be replaced with the current word from the wordlist. This lets you enumerate URL Parameters, Headers and much more.

Examples

gobuster fuzz -u https://example.com?FUZZ=test -w parameter-names.txt

s3 Mode

S3 mode tries to find valid Amazon S3 buckets.

Examples

gobuster s3 -w bucket-names.txt

gcs Mode

GCS mode is the same as S3, but for GCS (Google Cloud Storage)

Examples

gobuster gcs -w bucket-names.txt

tftp Mode

TFTP mode allows you to find files on a TFTP server. TFTP servers have no file listing so using this mode you can try to find files hosted by the tftp server.

Examples

gobuster tftp -s tftp.example.com -w common-filenames.txt

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. When supplying patterns, words from the wordlist will not be tried by themselves. If you wish to have patterns and plain words from the wordlist, place {GOBUSTER} on a line by itself in the pattern file.

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

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

gobuster s3 --wordlist my.custom.wordlist -p patterns.txt -v

Normal sample run goes like this:

PS C:\Users\firefart\Documents\code\gobuster> .\gobuster.exe s3 --wordlist .\wordlist.txt
