This module quickly fires up a web server that serves a payload.
|
|
The provided command will start the specified scripting language interpreter and then download and execute the
|
|
payload. The main purpose of this module is to quickly establish a session on a target
|
|
machine when the attacker has to manually type in the command himself, e.g. Command Injection,
|
|
RDP Session, Local Access or maybe Remote Command Exec. This attack vector does not
|
|
write to disk so it is less likely to trigger AV solutions and will allow privilege
|
|
escalations supplied by Meterpreter. When using either of the PSH targets, ensure the
|
|
payload architecture matches the target computer or use SYSWOW64 powershell.exe to execute
|
|
x86 payloads on x64 machines.
