3. Perform OS Discovery
Identifying the OS used on the target system allows you to assess the system’s vulnerabilities and the exploits that might work on the system to perform additional attacks.
1. Identify OS with TTL in wireshark
Follow TCP stream in wireshark. Check the ICMP reply after pinging. If TTL is around 128, its Windows, if around 64, its Linux
2. Perform OS Discovery using NSE scripting Engine
sudo nmap -O 192.168.18.110
sudo nmap -A 192.168.18.110Enumerating OS details with nmap script over smb
sudo nmap --script smb-os-discovery.nse 192.168.18.110
3. Unicornscan
unicornscan 192.168.18.100 - Iv-I is for immediate scan and v is for verbose scan.
