Firewall Evasion

• Start with a ping pack and work yourself up from there
• Use or replace existing services with your own malicious ones
  • e.g.: a Web Server is running, shut it down with service apache2 stop && service --status-all and reuse it port for your own server
• Flush/Disable the firewall
  • Windows:
    • NetSh Advfirewall set allprofiles state off
    • Set-NetFirewallProfile -Profile Domain,Public,Private -Enabled False
  • Linux: iptables -F
