Bug Bounty Recon with Nmap

Step 1: Install Nmap
If you're using Kali Linux, Nmap should already be installed. If not, you can install it using the following command:

sudo apt update
sudo apt install nmap

Step 2: Determine Target Scope
Decide on the scope of your bug bounty reconnaissance. This could be a specific domain, IP range, or target organization.

Step 3: Scan for Live Hosts
Run an initial scan to identify live hosts within your target scope. Replace target with your desired target (domain, IP range, etc.).

nmap -sn target

Step 4: Perform Service Detection
Once you've identified live hosts, perform service detection to determine which services are running on each host. This will help you identify potential attack vectors.

nmap -sV target

Step 5: Scan for Open Ports
Conduct a comprehensive scan to identify open ports and services on each live host. This will provide more detailed information about potential entry points.

nmap -p- target

Step 6: Conduct Version Detection
Perform version detection to identify specific versions of services running on open ports. This information can help you determine if any known vulnerabilities exist.

nmap -sV -p<ports> target

Replace <ports> with a comma-separated list of ports you want to scan.
Example:

nmap -sV -p80,443 example.com

Step 7: Conduct OS Detection (Optional)
Optionally, you can conduct OS detection to determine the operating system running on each host.

nmap -O target

Step 8: Perform Aggressive Scan (Optional)
For a more aggressive scan, use the -A flag to enable OS detection, version detection, script scanning, and traceroute.

nmap -A target

Step 9: Analyze Results
Review the scan results to identify potential vulnerabilities or misconfigurations. Pay attention to open ports, services, and version numbers.

Step 10: Further Enumeration (Optional)
Depending on the results of your initial scans, you may want to conduct further enumeration using additional tools or techniques, such as vulnerability scanners, web application scanners, or manual testing.
