- How to use Powershell in an exploit · rapid7/metasploit-framework Wiki
PowerShell is a scripting language developed by Microsoft. It provides API access to almost everything in a Windows platform, less detectable by countermeasures, easy to learn, therefore it is incredibly powerful for penetration testing during post exploitation, or exploit development for payload execution. Take Metasploit’s windows/smb/psexec_psh.rb module for example: it mimics the psexec utility from SysInternals, the payload is compressed and executed from the command line, which allows it to be somewhat stealthy against antivirus. There’s only less than 30 lines of code in psexec_psh.rb (excluding the metadata that describes what the module is about), because most of the work is done by the Powershell mixin, nothing is easier than that. The command line will automatically attempt to detect the architecture (x86 or x86_64) that it is being run in, as well as the payload architecture that it contains. If there is a mismatch it will spawn the correct PowerShell architecture to inject the payload into, so there is no need to worry about the architecture of the target system.

- SSH_VPN – Community Help Wiki – This page discusses using SSH to set up SSH-based point to point connections, which can then be used to create routes that create virtual private networks. Note that using SSH in this fashion is not the "best" way to create a permanent, stable VPN. Notably, SSH uses TCP, and TCP over TCP can provide abysmal performance under pathological conditions.
- VPN over SSH – This how-to is intended to cover the details of how to establish a VPN (Virtual Private Network) over a SSH connection. Starting with open-ssh 4.3, you can now use a ssh connection to set up a VPN. This is technically termed "layer-3 IP-in-SSH tunnelling" and is not using ssh to port forward (ssh -L ) or create a dynamic "application level" forwarding (SOCKS) (ssh -D ). Rather a VPN is established using a SSH connection to create a virtual interface, tun0. Advantages : IMO, this technique is easier to set up then openvpn, especially if you are using a single client. Works with most Linux distributions without the need to install any additional software on the clients. The server only needs openssh-server. This protocol uses udp to transmit tunneled tcp connections resulting in a more stable connection compared with port forwarding (using ssh with the -L or -D options). Disadvantages : As of yet I do not know of a windows client which will use this protocol. If you are needing to set up a VPN with numerous clients I would use openvpn. Although there are several "how-to's" on the web, most of them assume you know something about networking and routing. This page attempts to explain some of the "missing details".
