Forum Thread: How Does a Reverse Tcp Bring Up a Shell?

I know how a reverse-tcp connects to a computer, and how it uses things like a buffer overflow to get a root shell, but how does it take the attacker's input and execute the commands inputted? The reason I ask this is because from my experience, TCP makes a connection but not give a remote shell, but with something like SSH, you get a remote shell. So therefore I was wondering how you get the remote shell in a reverse-tcp attack.

Forum Thread: "Hacking" with Physical Access

What is the best way to gain remote control (es. access to files, use a keylogger ecc) of a Windows pc if we have physical access? Imagine physical access for a small period of time, like 30sec-1min, es. insert a USB, double click on something, then unplug the usb. How can we do it? I know there are so-called "trojan" but they are often detected by antivirus programs.

Forum Thread: Hydra Syntax

I have been trying to hack into CCTV cameras while using hydra. I've used multiple syntaxs and none of them have worked. I was wondering in order to correctly run a syntax in hydra for a web login does the syntax has to have the PHPSESSID? That is the only syxtax I haven't run because I don't know it. And if that is the case is there a way to get around it?

Forum Thread: I Can't Seem to Run a Persistence Script! (Stupid? Maybe)

Hi internet folk, Well i want to run a persistence script as mentioned but everytime i try to run it, it says that the windows version of meterpreter is not supported with this script. I have tried migrating to a x86/windows process but that doesn't seem to work either. I'm also fairly new to exploiting but I have succeeded with rdp'ing to another computer and the problem begins when i try to run a persistent backdoor to the other computer. Hope somebody can help me with this. :P
