He demonstrated three evasions, each more elegant than the last.
Next, she needed a foothold. A public web server sat on the DMZ. Instead of brute-forcing or vulnerability scanning (both IDS triggers), she browsed it like a normal user, then used HTTP parameter pollution —adding duplicate id parameters to a login form. The web server’s backend merged them in a way that bypassed authentication. The IDS saw only id=123 and id=456 . Normal traffic. He demonstrated three evasions, each more elegant than
She tested the next target. Malformed ICMP. The response came back in 0.3ms—too fast for any real kernel. Honeypot. Instead of brute-forcing or vulnerability scanning (both IDS
Maya followed along on her own isolated virtual network. She launched a standard Nmap scan against a target Linux box—immediately, a custom Snort rule triggered a red alert on her monitoring screen. DETECTED. Normal traffic
