Module Ranking and Traits

---

Module Ranking:

• manual: The exploit is unstable or difficult to exploit and is basically a DoS. This ranking is also used when the module has no use unless specifically configured by the user (e.g.: exploit/windows/smb/psexec). More information about ranking can be found here.

Basic Usage

---

msf > use encoder/x86/context_cpuid
msf encoder(context_cpuid) > show targets
    ... a list of targets ...
msf encoder(context_cpuid) > set TARGET target-id
msf encoder(context_cpuid) > show options
    ... show and set options ...
msf encoder(context_cpuid) > exploit
