Key Components:

Wordlist - Source of potential directory/subdomain names
Mode - Determines enumeration type (dir/dns/vhost)
Concurrency - Multiple threads for parallel testing
Filtering - Status code and response size filtering
Output - Results in various formats (stdout, JSON, CSV)

Mode 1: Directory and File Brute-Forcing (dir)

The dir mode discovers hidden directories and files on web servers.

Basic Directory Enumeration

gobuster dir -u http://testphp.vulnweb.com -w /usr/share/wordlists/dirb/common.txt

Advanced Directory Scanning

Multiple File Extensions

Test for multiple file types simultaneously:

gobuster dir -u http://testphp.vulnweb.com \
  -w /usr/share/seclists/Discovery/Web-Content/raft-medium-directories.txt \
  -x php,html,txt,xml,js,zip,bak,old \
  -t 50 \
  -s 200,204,301,302,307,401,403

Flag Breakdown:

-x php,html,txt,xml,js,zip,bak,old - Test eight extensions per word
-t 50 - Use 50 threads for faster scanning
-s 200,204,301,302,307,401,403 - Show only these status codes

Recursive Directory Scanning

Automatically scan discovered subdirectories:

gobuster dir -u http://testphp.vulnweb.com \
  -w /usr/share/seclists/Discovery/Web-Content/common.txt \
  -r \
  -x php,html

Flag Breakdown:

-r - Enable recursive scanning (follows redirects to discovered directories)
-x php,html - Check for PHP and HTML files

Note: Gobuster’s -r flag follows redirects but does not support depth control. For recursive scanning with depth limits, consider alternative tools like Feroxbuster (with -L flag) or ffuf (with -recursion-depth).

Recursive scanning can generate significant traffic. Monitor your scan and use --delay to avoid overwhelming the target or triggering security controls.

Custom HTTP Headers

Add authentication or custom headers:

gobuster dir -u http://testphp.vulnweb.com \
  -w /usr/share/wordlists/dirb/common.txt \
  -H "Authorization: Bearer YOUR_TOKEN_HERE" \
  -H "X-Custom-Header: value" \
  -a "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36"

Flag Breakdown:

-H "Authorization: Bearer TOKEN" - Add authentication header
-H "X-Custom-Header: value" - Add custom header
-a "User-Agent" - Spoof User-Agent string

Following Redirects

Automatically follow HTTP redirects:

gobuster dir -u http://testphp.vulnweb.com \
  -w /usr/share/wordlists/dirb/common.txt \
  -f \
  -r

Flag Breakdown:

-f - Append / to directory requests (forces directory listing)
-r - Follow redirects

Status Code Reference

Understanding HTTP status codes helps interpret results:

Status Code	Meaning	Action
200 OK	Resource exists and accessible	Investigate content
204 No Content	Request successful, no body	May indicate API endpoint
301 Moved Permanently	Permanent redirect	Follow redirect location
302 Found	Temporary redirect	Follow redirect location
307 Temporary Redirect	Method preserved redirect	Follow redirect
401 Unauthorized	Authentication required	Interesting finding - needs credentials
403 Forbidden	Access denied	Exists but restricted - try bypass techniques
404 Not Found	Resource doesn’t exist	Filtered out by default
500 Internal Server Error	Server error	May indicate vulnerable endpoint
503 Service Unavailable	Service temporarily down	May need to slow down scan

Filtering Techniques

Exclude by Length

Filter out responses by body length:

gobuster dir -u http://testphp.vulnweb.com \
  -w /usr/share/wordlists/dirb/common.txt \
  --exclude-length 1234

--exclude-length 1234 - Ignore responses with 1234 bytes

Useful when the server returns custom 404 pages with consistent length.

Pattern File Usage

Use pattern files to apply transformations to wordlist entries:


gobuster dir -u http://testphp.vulnweb.com \
  -w /usr/share/wordlists/dirb/common.txt \
  -p patterns.txt

-p patterns.txt - Apply patterns from file (replaces {GOBUSTER} with each wordlist entry)

Note: The -p flag is for pattern file transformations, not content filtering. For filtering response content, use --exclude-length to filter by body size or -b to exclude status codes.

Mode 2: DNS Subdomain Enumeration (dns)

The dns mode discovers subdomains through DNS brute-forcing.

Basic DNS Enumeration

gobuster dns -d example.com \
  -w /usr/share/seclists/Discovery/DNS/subdomains-top1million-5000.txt

Advanced DNS Scanning

Custom DNS Resolver

Use specific DNS servers:

gobuster dns -d example.com \
  -w /usr/share/seclists/Discovery/DNS/subdomains-top1million-20000.txt \
  -r 8.8.8.8,8.8.4.4

Flag Breakdown:

-r 8.8.8.8,8.8.4.4 - Use Google’s public DNS servers
Useful when target’s DNS servers are rate-limiting or filtering

Show CNAMEs and IPs

Display detailed DNS records:

gobuster dns -d example.com \
  -w /usr/share/seclists/Discovery/DNS/subdomains-top1million-5000.txt \
  -i \
  -c

Flag Breakdown:

-i - Show IP addresses of discovered subdomains
-c - Show CNAME records

Sample Output:

Found: www.example.com [192.0.2.1]
Found: mail.example.com [CNAME: mail-server.example.net]
Found: cdn.example.com [CNAME: cdn-provider.net] [203.0.113.10]

Wildcard Detection

Handle wildcard DNS configurations:

gobuster dns -d example.com \
  -w /usr/share/seclists/Discovery/DNS/subdomains-top1million-5000.txt \
  --wildcard

--wildcard - Force wildcard detection and filtering

Some domains use wildcard DNS (*.example.com resolves to the same IP). Gobuster detects this automatically, but --wildcard forces explicit handling if detection fails.

    style E fill:#CA9161,stroke:#000,color:#000
    style F fill:#0173B2,stroke:#000,color:#fff
    style G fill:#DE8F05,stroke:#000,color:#000
    style H fill:#029E73,stroke:#000,color:#fff

Recommended Wordlists for DNS:

Quick scan: subdomains-top1million-5000.txt (5,000 entries)
Thorough scan: subdomains-top1million-20000.txt (20,000 entries)
Comprehensive scan: subdomains-top1million-110000.txt (110,000 entries)

Mode 3: Virtual Host Discovery (vhost)

The vhost mode discovers virtual hosts on a web server by testing different Host headers.

What are Virtual Hosts?

Virtual hosts allow multiple websites to run on the same IP address. The server determines which site to serve based on the HTTP Host header.

Example Scenario:

Server IP: 192.0.2.100
Virtual hosts: example.com, dev.example.com, admin.example.com
All use the same IP but serve different content

Basic Virtual Host Enumeration

gobuster vhost -u http://example.com \
  -w /usr/share/seclists/Discovery/DNS/subdomains-top1million-5000.txt \
  --append-domain

Flag Breakdown:

gobuster vhost - Use virtual host enumeration mode
-u http://example.com - Target base URL
--append-domain - Append base domain to wordlist entries

How it works:

Gobuster sends requests to http://example.com
Each request uses different Host header: Host: admin.example.com
Server responses differ based on virtual host configuration
Results filtered by response size/status code

Advanced Virtual Host Scanning

Filtering by Response Size

Virtual host enumeration often produces false positives. Filter by response length:

gobuster vhost -u http://192.0.2.100 \
  -w /usr/share/seclists/Discovery/DNS/subdomains-top1million-5000.txt \
  --append-domain \
  --domain example.com \
  --exclude-length 12345

Flag Breakdown:

-u http://192.0.2.100 - Target IP directly
--domain example.com - Base domain for Host header
--exclude-length 12345 - Filter out responses with 12345 bytes (default page size)

Domain Variations

Test different domain patterns:

gobuster vhost -u http://192.0.2.100 \
  -w wordlist-custom.txt \
  --domain example.com

Virtual Host vs DNS Enumeration

Understanding the difference helps choose the right mode:

Feature	DNS Mode	VHost Mode
Method	DNS queries	HTTP Host header
Discovery	Subdomains in DNS	Virtual hosts on server
Requires	DNS resolution	Direct HTTP access
Finds	Public subdomains	Hidden virtual hosts
Best for	External reconnaissance	Internal/development hosts

Use DNS mode when:

Mapping public infrastructure
Discovering external subdomains
Initial reconnaissance phase

Use VHost mode when:

Target has multiple virtual hosts on one IP
Looking for development/staging environments
DNS doesn’t reveal all subdomains

Output Formats and Reporting

Save scan results in various formats for documentation and analysis.

Standard Output to File

Redirect output to text file:

gobuster dir -u http://testphp.vulnweb.com \
  -w /usr/share/wordlists/dirb/common.txt \
  -o results-directories.txt

-o results-directories.txt - Save output to file

JSON Format

Export results as JSON for programmatic analysis:

gobuster dir -u http://testphp.vulnweb.com \
  -w /usr/share/wordlists/dirb/common.txt \
  -o results.json \
  --no-error

Sample JSON Output:

{
  "url": "http://testphp.vulnweb.com/admin",
  "status": 301,
  "size": 185,
  "redirect": "http://testphp.vulnweb.com/admin/"
}

Progress Output

Show detailed progress during scan:

gobuster dir -u http://testphp.vulnweb.com \
  -w /usr/share/wordlists/dirb/common.txt \
  --no-progress \
  -q

Flag Breakdown:

--no-progress - Disable progress bar
-q - Quiet mode (only show results)

Useful for scripting and automation.

Wordlist Selection and Strategy

Choosing the right wordlist significantly impacts scan effectiveness.

Wordlist Categories

Directory and File Wordlists

Quick scans (common.txt, small.txt)
- 1,000-5,000 entries
- Common directories like /admin, /login, /config
Medium scans (raft-medium-directories.txt)
- 20,000-30,000 entries
- Balanced between speed and coverage
Comprehensive scans (raft-large-directories.txt)
- 60,000-100,000 entries
- Thorough enumeration, longer scan times

Technology-Specific Wordlists

Target specific platforms:

gobuster dir -u http://wordpress-site.com \
  -w /usr/share/seclists/Discovery/Web-Content/CMS/wordpress.fuzz.txt \
  -x php

gobuster dir -u http://joomla-site.com \
  -w /usr/share/seclists/Discovery/Web-Content/CMS/joomla.fuzz.txt

gobuster dir -u http://api.example.com \
  -w /usr/share/seclists/Discovery/Web-Content/api/api-endpoints.txt \
  -x json,xml

Custom Wordlist Creation

Create custom wordlists based on reconnaissance:

cewl http://example.com -m 5 -w custom-wordlist.txt

cat common.txt medium.txt | sort -u > combined.txt

gobuster dir -u http://example.com -w combined.txt

  -o scan-aspnet.txt

Advanced Troubleshooting

Problem: Wildcard Responses

Symptom: Server returns 200 OK for all requests, even non-existent paths.

Diagnosis:

curl -I http://example.com/this-definitely-does-not-exist-12345

If this returns 200 OK, the server has wildcard configuration.

Solutions:

Filter by response length:

curl -s http://example.com/random12345 | wc -c

gobuster dir -u http://example.com \
  -w /usr/share/wordlists/dirb/common.txt \
  --exclude-length 4523

Filter by content pattern:

gobuster dir -u http://example.com \
  -w /usr/share/wordlists/dirb/common.txt \
  -p "404,not found,error"

Problem: Rate Limiting or Blocking

Symptom: Scan stops, receives 429 Too Many Requests, or 503 Service Unavailable.

Solutions:

gobuster dir -u http://example.com \
  -w /usr/share/wordlists/dirb/common.txt \
  -t 5

gobuster dir -u http://example.com \
  -w /usr/share/wordlists/dirb/common.txt \
  -t 10 \
  --delay 200ms

gobuster dir -u http://example.com \
  -w /usr/share/wordlists/dirb/common.txt \
  -a "Mozilla/5.0 (Windows NT 10.0; Win64; x64) Chrome/91.0"

Problem: SSL/TLS Certificate Errors

Symptom: x509: certificate signed by unknown authority

Solution:

gobuster dir -u https://example.com \
  -w /usr/share/wordlists/dirb/common.txt \
  -k

-k - Skip SSL certificate verification

Only use -k flag on systems you control or in testing environments. Skipping certificate verification in production environments defeats TLS security.

Problem: No Results Found

Troubleshooting Checklist:

Verify target is accessible:

curl -I http://example.com

Test with known existing path:

gobuster dir -u http://example.com -w <(echo "index")

Try different wordlist:

gobuster dir -u http://example.com \
  -w /usr/share/seclists/Discovery/Web-Content/raft-small-words.txt

Check status code filtering:

gobuster dir -u http://example.com \
  -w /usr/share/wordlists/dirb/common.txt \
  -s 200,204,301,302,307,401,403,405,500

Increase verbosity:

gobuster dir -u http://example.com \
  -w /usr/share/wordlists/dirb/common.txt \
  -v

-v - Verbose output showing all requests
