A seems the better choice as you'd expect an APT to work around simpy having their IP adresses blocked

Agreed. implementing an IPS rule that includes content for the malware variant, the organization can prevent malicious traffic from reaching the routers. Additionally, patching the routers to protect against the vulnerability will further reduce the risk of compromise.

Selected Answer: C
I'm going with C. To protect against this threat, the organization should implement an IPS rule that contains the IP addresses associated with the APT. This will allow the IPS to detect and block any traffic from these IP addresses, preventing the APT from accessing the network. Additionally, the organization should patch the routers to fix the vulnerability that the APT is exploiting. This will prevent the APT from being able to gain access to the routers even if they manage to bypass the IPS.
