Security+ SY0-701 · Hands-on Lab

On-Path DNS Spoofing

Authorized engagement against an isolated test segment. You'll position yourself between a workstation and its gateway, falsify a DNS answer, and redirect a domain to an attacker-controlled clone — then reason about the defenses that stop it.
Objective 2.4
Engagement brief. Cedarline Gear hired you to demonstrate the impact of an unsegmented flat network. On the lab segment 10.10.20.0/24 your Kali host is 10.10.20.50. A finance workstation, ws-finance-04 (10.10.20.115), reaches the internet through gateway 10.10.20.1. Your goal: make summitvalegear.com resolve to your own host so the workstation lands on a credential-capture clone instead of the real storefront.
