This module is a direct copy/paste of the Invoke-InveighRelay function
from the standalone version of Inveigh. The module will relay incoming
HTTP NTLMv2 authentication requests to an SMB target. If authentication
is successful and the user is a local administrator on the target
system, the specified command should be executed on the target PSexec
style. This module can be used with or without collection/inveigh. If
collection/inveigh is used, ensure that HTTP is disabled in
collection/inveigh. If this module is used without collection/inveigh,
another method will need to be employed to trigger incoming HTTP
requests.
This module has been successfully tested with Empire's launcher
one-liner to establish additional agents. In testing I observed a delay
(30 seconds or so) between the service creation message and Empire's
agent active message.
harmj0y: As I mentioned in the collection/inveigh pull request comments,
the length of the parameter names is throwing off Empire's options
command column display alignment. I'm not sure if there is an easy fix
for this. Also, I used the same code that you added to inveigh.py after
the pull request. With this code, I did not observe that the
SMBRelayCommand value needed to be wrapped in quotes.
Direct copy/paste of Invoke-Inveigh function from current standalone
version of Inveigh. This version contains a number of
additions/changes/bug fixes. There are two primary additions that may be
useful to Empire users. The first is that 1122334455667788 is no longer
used as the default challenge over HTTP since it's now getting flagged
by SEP and maybe others. The default behavior is a random challenge for
each request. A specific challenge can also be specified through the
'challenge' parameter. The second is the ability to set a run time so
that collection/inveigh will auto-exit after a specified number of
minutes. On the python side, I have added the additional relevant
parameters and flipped the module to opsec safe since no files are
created on disk.
