Probably SSH is not as clean and fast as other useful tools like netcat, but it has some features which are very useful, and when you'll need them, here's how to behave with that huge amount of computers all over your house. Probably, you already know what SSH means, but for ...more
Welcome back, my fledgling hackers! Sometimes, for a variety of reasons, we can only get a command shell on our target system. For instance, with Metasploit, it's not always possible to get the all powerful Meterpreter on our target system. In other cases, we may be able to c ...more
If you've been watching the latest USA TV Series Mr Robot, you will have seen the Raspberry Pi used by Fsoeciety to control the HVAC system. OTW covers this very well here with his take on setup they may of used. However I had a very different take. A netcat bind shell is gre ...more
Proxies can be quicker to use than a VPN for specific applications, like web browsers or torrent clients. Both services will hide your true IP address, but a VPN is slowed down because it encrypts all data through a VPN network, while a proxy just acts as a middleman for fetch ...more
