- 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.
