|
|
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 less likely to trigger AV solutions and will allow privilege
|
|
escalations supplied by Meterpreter. Ensure the payload architecture matches the
|
|
target computer or use SYSWOW64 powershell.exe to execute x86 payloads on x64 machines.
