'Description' => %q{
|
|
This module quickly fires up a web server that serves the payload in powershell.
|
|
The provided command will start powershell and then download and execute the
|
|
payload. The IEX command can also be extracted to execute directly from powershell.
|
|
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. RDP
|
|
Session, Local Access or maybe Remote Command Exec. This attack vector does not
|
|
write to disk so is unlikely to trigger AV solutions and will allow to attempt local
|
|
privilege escalations supplied by meterpreter etc. You could also try your luck with
|
|
social engineering. Ensure the payload architecture matches the target computer or
|
|
use SYSWOW64 powershell.exe to execute x86 payloads on x64 machines.
