matcher := filter.NewMatcher(options.Matchers, options.MatcherMode)
filter := filter.NewFilter(options.Filters, options.FilterMode)

Gobuster:

wordlist, err := gobusterdir.NewWordlist(options.Wordlist, options.WLDirect)
if err != nil {
    return fmt.Errorf("failed to create wordlist: %w", err)
}

Both tools are written in Go and utilize similar concepts for handling wordlists and filtering. However, ffuf's code structure allows for more advanced filtering and matching capabilities, while Gobuster's approach is more straightforward and easier to understand for beginners.

dirsearch

11,823

Web path scanner

Pros of dirsearch

Written in Python, making it more accessible for scripting and modifications
Supports multiple wordlists and extensions simultaneously
Includes a recursive scanning feature out-of-the-box

Cons of dirsearch

Generally slower performance compared to Gobuster
Less optimized for handling large-scale scans efficiently

Code Comparison

dirsearch:

def recursive_scan(self, base_path):
    for item in self.dictionary:
        new_path = base_path + "/" + item
        self.scan(new_path)

Gobuster:

func (g *Gobuster) worker(ctx context.Context, wordChan <-chan string, resultChan chan<- Result) {
    for {
        select {
        case <-ctx.Done():
            return
        case word := <-wordChan:
            g.processWord(ctx, word, resultChan)
        }
    }
}

The code snippets showcase the different approaches to scanning. dirsearch uses a recursive function for directory traversal, while Gobuster employs a worker-based concurrent model for improved performance.

Both tools are effective for directory and file brute-forcing, with dirsearch offering more built-in features and flexibility, while Gobuster excels in speed and efficiency for larger scans.

httpx

7,441

httpx is a fast and multi-purpose HTTP toolkit that allows running multiple probes using the retryablehttp library.

Pros of httpx

Faster and more efficient for large-scale scanning due to its concurrent design
Provides more detailed output, including HTTP response headers and status codes
Supports multiple input formats (e.g., STDIN, file) and output formats (e.g., JSON, CSV)

Cons of httpx

Less focused on directory and file enumeration compared to gobuster
May require more system resources due to its concurrent nature
Steeper learning curve for users familiar with simpler tools like gobuster

Code Comparison

httpx:

probes, err := httpx.New(&httpx.Options{
    Methods:         methods,
    Retries:         retries,
    Threads:         threads,
    Timeout:         timeout,
    MaxRedirects:    maxRedirects,
    CustomHeaders:   customHeaders,
    FollowRedirects: followRedirects,
})

gobuster:

gobuster := libgobuster.NewGobuster(globalopts, opts)
if err := gobuster.Run(); err != nil {
    fmt.Fprintf(os.Stderr, "Error on running gobuster: %s\n", err)
    os.Exit(1)
}

Both tools are written in Go and offer command-line interfaces for web enumeration tasks. httpx focuses on HTTP probing and analysis, while gobuster specializes in directory and file brute-forcing. httpx provides more flexibility and detailed output, making it suitable for complex scanning scenarios. gobuster, on the other hand, offers a simpler approach for targeted enumeration tasks.

assetfinder

2,964

Find domains and subdomains related to a given domain

Pros of assetfinder

Specifically designed for discovering subdomains and related assets
Lightweight and fast, with minimal dependencies
Supports multiple data sources for comprehensive asset discovery

Cons of assetfinder

Limited to subdomain discovery, lacking directory/file enumeration capabilities
May require additional tools for a complete reconnaissance workflow
Less actively maintained compared to gobuster

Code Comparison

assetfinder:

func main() {
    domain := flag.String("domain", "", "The domain to find assets for")
    flag.Parse()
    for result := range assetfinder.Run(*domain) {
        fmt.Println(result)
    }
}

gobuster:

func main() {
    globalopts := parseGlobalOptions()
    plugin := parsePlugin(globalopts)
    ctx, cancel := context.WithCancel(context.Background())
    defer cancel()
    plugin.Run(ctx, globalopts)
}

The code snippets show that assetfinder is more focused on subdomain discovery, while gobuster offers a plugin-based architecture for various enumeration tasks. gobuster's design allows for greater flexibility in performing different types of scans, whereas assetfinder is specialized for asset discovery.

Both tools are valuable for reconnaissance, with assetfinder excelling in subdomain enumeration and gobuster providing a more versatile platform for various enumeration tasks. The choice between them depends on the specific requirements of the security assessment or penetration testing engagement.

Changes

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

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

3.4

Enable TLS1.0 and TLS1.1 support
Add TFTP mode to search for files on tftp servers

3.3

Support TLS client certificates / mtls
support loading extensions from file
support fuzzing POST body, HTTP headers and basic auth
new option to not canonicalize header names

3.2

Use go 1.19
use contexts in the correct way
get rid of the wildcard flag (except in DNS mode)
color output
retry on timeout
google cloud bucket enumeration
fix nil reference errors

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

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

License

See the LICENSE file.

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.

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 (at least go 1.19), it's as easy as:

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

PS: You need at least go 1.19 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 1.19 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

Modes

Help is built-in!

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

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

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:
