Description:
Meterpreter_Paranoid_Mode.sh allows users to secure your staged/stageless
connection for Meterpreter by having it check the certificate of the
handler it is connecting to.
We start by generating a certificate in PEM format, once the certs have
been created we can create a HTTP or HTTPS or EXE payload for it and give
it the path of PEM format certificate to be used to validate the connection.
To have the connection validated we need to tell the payload what certificate
the handler will be using by setting the path to the PEM certificate in the
HANDLERSSLCERT option then we enable the checking of this certificate by
setting stagerverifysslcert to true.
Once that payload is created we need to create a handler to receive the
connection and again we use the PEM certificate so the handler can use the
SHA1 hash for validation. Just like with the Payload we set the parameters
HANDLERSSLCERT with the path to the PEM file and stagerverifysslcert to true.
We can see the stage doing the validation when we recibe a session back ..
Exploitation:
Meterpreter_Paranoid_Mode tool starts posgresql service, builds the PEM certificate,
builds payload (staged OR stageless), starts the comrespondent handler associated to
the PEM certificate created (manual) OR impersonated (msf auxliary module) runs msf
post-exploitation modules at session creation, deliver agents (staged or stageless)
using hta attack vector (apache2 + hta + agent) if configurated in the settings file.
Payloads available:
Staged (payload.bat|ps1|txt|exe):
windows/meterpreter/reverse_winhttps
windows/meterpreter/reverse_https
windows/x64/meterpreter/reverse_https
Stageless (binary.exe):
windows/meterpreter_reverse_https
windows/x64/meterpreter_reverse_https
Dependencies/Limitations:
xterm, zenity, metasploit, postgresql
WARNING: This tool will NOT evade AV detection, its made to prevent the data
beeing transmited from client (payload) to server beeing captured (Eavesdropping)
WARNING: If you decided to use a 64bit payload, then edit settings file and change
'MSF_ENCODER=x86/shikata_ga_nai' to one payload arch compatible encoder(64bit)
WARNING: Only in 'staged' builds, Users are allowed to chose the extension (bat|ps1|txt|exe)
Config Settings file (warning: case sensitive)
msf postgresql database connection check? (msfdb reinit)
using the encoder + unicode_encoder sellected on settings file (default: x86/shikata_ga_nai)
HTA attack vector (deliver agent in local lan using apache2)
Default msf post module to run at session creation
