You Should Know:
Bug hunting is a critical skill in cybersecurity, and mastering tools like Google Dorking and Fuzzing can significantly enhance your ability to uncover vulnerabilities. Below are some practical steps, commands, and codes to help you get started with these techniques.
Google Dorking Commands:
Google Dorking involves using advanced search operators to find sensitive information or vulnerabilities. Here are some useful dorks:
1. Find exposed directories:
intitle:"index of" "parent directory"
2. Search for exposed configuration files:
filetype:env intext:DB_PASSWORD
3. Locate exposed login pages:
intitle:"login" "admin"
4. Find exposed databases:
inurl:/phpmyadmin/index.php
5. Search for exposed API keys:
"api_key" ext:txt
Fuzzing Techniques:
Fuzzing is the process of sending malformed or unexpected data to an application to uncover vulnerabilities. Here are some tools and commands to get started:
1. Using FFuf (Fast Web Fuzzer):
- Install FFuf:
sudo apt install ffuf
- Basic directory fuzzing:
ffuf -w /path/to/wordlist.txt -u http://example.com/FUZZ
- Parameter fuzzing:
ffuf -w /path/to/wordlist.txt -u http://example.com/?param=FUZZ
2. Using Wfuzz:
- Install Wfuzz:
sudo apt install wfuzz
- Directory fuzzing:
wfuzz -c -z file,/path/to/wordlist.txt --hc 404 http://example.com/FUZZ
3. Using Burp Suite for Fuzzing:
- Configure Burp Suite to intercept requests.
- Use the Intruder tool to fuzz parameters with a payload list.
Practice Commands:
Here are some Linux commands to help you automate and manage your bug-hunting tasks:
1. Extract URLs from a file:
grep -oP 'http[s]?://[^"]+' file.txt
2. Monitor network traffic:
sudo tcpdump -i eth0 -w output.pcap
3. Scan for open ports:
nmap -sV -p 1-65535 target.com
4. Check for subdomains:
assetfinder target.com
5. Extract JavaScript files from a website:
curl -s http://example.com | grep -oP '(?<=src=")[^"]*.js(?=")'
What Undercode Say:
