But the firewall logs spikes. Alex pivots: . Alex, ethical hacker

Alex, ethical hacker. 1. Firewall Evasion – The First Glance Alex scans the external perimeter. A classic nmap -sS triggers port 80 (HTTP) and 443 (HTTPS) only. Firewall is stateful—drops unsolicited SYN packets to other ports.

Alex notices port 443 allows ICMP tunneling (misconfigured firewall rule allowing ICMP echo replies). Uses ptunnel to encapsulate TCP over ICMP. Firewall sees ping packets – no alert. 2. IDS/IPS Evasion – The Web App Gateway Inside the DMZ, an IDS sniffs traffic. Alex’s ICMP tunnel reaches a vulnerable web server. A simple curl request for /cgi-bin/test.cgi?cmd=ls triggers a signature (known attack pattern).

Alex uses fragmentation and decoy scans :
