VPS for Bug Bounty & Pentesting
https://lnkd.in/dXUVkCPT
You Should Know:
Using a VPS (Virtual Private Server) for bug bounty hunting and penetration testing can significantly enhance your capabilities. Below are some practical steps, commands, and tools to get started:
1. Setting Up Your VPS for Reconnaissance
- Choose a VPS Provider: Popular options include DigitalOcean, Linode, and AWS.
- Install Recon Tools: Use the following commands to install essential tools:
sudo apt update sudo apt install -y nmap masscan subfinder amass dirsearch gobuster
- Configure Masscan for Large-Scale Scanning:
sudo masscan -p1-65535 <target_ip> --rate=10000 -oG output.txt
2. Automating Recon with Bash Scripts
Create a simple bash script to automate subdomain enumeration and port scanning:
#!/bin/bash target=$1 subfinder -d $target -o subdomains.txt amass enum -d $target -o amass.txt cat subdomains.txt amass.txt | sort -u > final_subdomains.txt nmap -iL final_subdomains.txt -oA nmap_scan
#### **3. Using VPS for Bug Bounty**
- Install Web Vulnerability Scanners:
sudo apt install -y nikto wapiti wpscan
- Run a Basic Nikto Scan:
nikto -h <target_url> -o nikto_scan.txt
#### **4. Pentesting with VPS**
- Install Metasploit Framework:
curl https://apt.metasploit.com/metasploit-framework.gpg.key | sudo gpg --dearmor -o /usr/share/keyrings/metasploit-archive-keyring.gpg echo "deb [signed-by=/usr/share/keyrings/metasploit-archive-keyring.gpg] https://apt.metasploit.com/ buster main" | sudo tee /etc/apt/sources.list.d/metasploit-framework.list sudo apt update sudo apt install -y metasploit-framework
- Launch Metasploit:
msfconsole
#### **5. Securing Your VPS**
- Enable Firewall:
sudo ufw enable sudo ufw allow ssh sudo ufw allow http sudo ufw allow https
- Harden SSH Access:
Edit `/etc/ssh/sshd_config` and set:
PermitRootLogin no PasswordAuthentication no
Restart SSH:
sudo systemctl restart sshd
### **What Undercode Say:**
Using a VPS for bug bounty and pentesting provides a scalable and isolated environment for security research. By leveraging tools like Masscan, Nikto, and Metasploit, you can automate reconnaissance and vulnerability discovery. Always ensure your VPS is secured with firewalls and hardened SSH configurations to prevent unauthorized access. For further reading, check out the VPS for Bug Bounty & Pentesting guide.
**Additional Commands for Linux/Windows:**
- Linux:
</li> </ul> <h1>Check open ports</h1> netstat -tuln <h1>Monitor network traffic</h1> sudo tcpdump -i eth0 <h1>Find files with SUID permissions</h1> find / -perm -4000 -type f 2>/dev/null
– Windows:
<h1>List open ports</h1> netstat -an <h1>Check firewall rules</h1> netsh advfirewall firewall show rule name=all <h1>Scan for vulnerabilities with PowerShell</h1> Invoke-WebRequest -Uri "http://<target_url>" -UseBasicParsing
By following these steps and commands, you can effectively utilize a VPS for cybersecurity tasks.
