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

Requirements: Go 1.24 or higher

Download pre-compiled binaries from the releases page.

# Pull the latest image
docker pull ghcr.io/oj/gobuster:latest

# Run gobuster in Docker
docker run --rm -it ghcr.io/oj/gobuster:latest dir -u https://example.com -w /usr/share/wordlists/dirb/common.txt

git clone https://github.com/OJ/gobuster.git
cd gobuster
go mod tidy
go build

If you encounter issues:

• Ensure Go version 1.24+ is installed: go version
• Check your $GOPATH and $GOBIN environment variables
• Verify $GOPATH/bin is in your $PATH

Gobuster uses a mode-based approach. Each mode is designed for specific enumeration tasks:

gobuster [mode] [options]

gobuster help                   # Show general help
gobuster help [mode]            # Show help for specific mode
gobuster [mode] --help          # Alternative help syntax

Enumerate directories and files on web servers.

Basic Usage:

gobuster dir -u https://example.com -w wordlist.txt

Advanced Options:

# With file extensions
gobuster dir -u https://example.com -w wordlist.txt -x php,html,js,txt

# With custom headers and cookies
gobuster dir -u https://example.com -w wordlist.txt -H "Authorization: Bearer token" -c "session=value"

# Show response length
gobuster dir -u https://example.com -w wordlist.txt -l

# Filter by status codes
gobuster dir -u https://example.com -w wordlist.txt -s 200,301,302

Discover subdomains through DNS resolution.

Basic Usage:

gobuster dns -d example.com -w wordlist.txt

Advanced Options:

# Use custom DNS server
gobuster dns -d example.com -w wordlist.txt -r 8.8.8.8:53

# Increase threads for faster scanning
gobuster dns -d example.com -w wordlist.txt -t 50

Discover virtual hosts on web servers.

Basic Usage:

gobuster vhost -u https://example.com --append-domain -w wordlist.txt

Enumerate Amazon S3 buckets.

Basic Usage:

gobuster s3 -w bucket-names.txt

With Debug Output:

gobuster s3 -w bucket-names.txt --debug

Enumerate files on tftp servers.

Basic Usage:

gobuster tftp -s 10.0.0.1 -w wordlist.txt

Enumerate Google Cloud Storage Buckets.

Basic Usage:

gobuster gcs -w bucket-names.txt

With Debug Output:

gobuster gcs -w bucket-names.txt --debug

Custom fuzzing with the FUZZ keyword.

Basic Usage:

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

Advanced Examples:

# Fuzz URL parameters
gobuster fuzz -u https://example.com?param=FUZZ -w wordlist.txt

# Fuzz headers
gobuster fuzz -u https://example.com -H "X-Custom-Header: FUZZ" -w wordlist.txt

# Fuzz POST data
gobuster fuzz -u https://example.com -d "username=admin&password=FUZZ" -w passwords.txt

# Comprehensive directory enumeration
gobuster dir -u https://target.com -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt -x php,html,js,txt,asp,aspx,jsp

# API endpoint discovery
gobuster dir -u https://api.target.com -w /usr/share/wordlists/dirb/common.txt -x json

# Admin panel discovery
gobuster dir -u https://target.com -w admin-panels.txt -s 200,301,302,403

# Comprehensive subdomain enumeration
gobuster dns -d target.com -w /usr/share/wordlists/dnsrecon/subdomains-top1mil-5000.txt -t 50

# S3 bucket enumeration with patterns
gobuster s3 -w company-names.txt -v

# GCS bucket enumeration
gobuster gcs -w company-names.txt -v

• Try reducing thread count with -t flag
• Add delays between requests with --delay
• Use different user agent with -a flag

• Increase timeout with --timeout flag
• Reduce thread count for slower targets
• Check your internet connection

• Verify the target URL is accessible
• Try different wordlists
• Check status code filtering with -s flag

• Increase thread count with -t flag (but be careful not to overwhelm the target)
• Use smaller, more targeted wordlists

1. Always get proper authorization before testing any target
2. Start with low thread counts to avoid overwhelming servers
3. Use appropriate wordlists for the target technology
4. Respect rate limits and implement delays if needed
5. Monitor your network traffic to avoid detection

• For web applications: Use technology-specific wordlists (PHP, ASP.NET, etc.)
• For APIs: Focus on common API endpoints and versioning patterns
• For DNS: Use subdomain-specific wordlists with common patterns
• For cloud storage: Use company/brand-specific patterns

# Save results to file
gobuster dir -u https://example.com -w wordlist.txt -o results.txt

# Use quiet mode for clean output
gobuster dir -u https://example.com -w wordlist.txt -q

Remember: Always test responsibly and with proper authorization.
