SSH port Forwarding (vps) As you all know, the major hazard of reverse-connecting RATs is they have to connect right back to you. And you won't always stay under the radar of system administrators. So use a VPN you say! VEry good. Except that most VPNs do not permit port forwarding of your external IP in a way that can be reliably used for reverse connecting backdoors. So what is an aspiring hacker to do? Get a VPS.
