By utilizing a port scanner, an attacker determined that ports 135 and 137 were listening on the target system. what does, if anything, this specific information tell the attacker?

Ports 135 and 137 are very helpful for the attacker because it means that the victim is trying to connect to a remote device or server. Most likely their own server, which means if they are the admin for a website server, they can harvest user credentials and either sell the information, use it as a cover up for their next few attacks, or they could get the Admins credentials, connect to a VPN server from Germany or Switzerland to cover their Public IP and destroy their server that they connected to.

Please message me if you have more questions like this. Although I am still learning to get my CEH, I still think like a hacker full-time :)
