Hi, I’m looking for a poke in the right direction as I’m stuck. I’ve tunneled through S***S (and even tried doing it twice to/through the host, hoping that it’d show up as a connection from localhost and let me in), but I keep getting 403 on the high port.
I’ve found the credentials in the S*P file. I haven’t been able to get a shell or user.txt at this point, but assume it’s because I need to get to the high port first. Can someone help me out please?
