Explanation

The attacker "brute forced a PIN to gain access" to the network. Using a PIN implies they used WPS to gain access to the network because WPS can be configured to require a simple 8 digit code - very vulnerable to brute forcing. "The attacker then modified the DNS settings on the router." That could only be done via admin credentials to the router. A default login could allow that access. (Many routers default to admin, admin for login and password.)
