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. In the next prompt choose payload category for auto-building payload, from the given list I chose stagless (payload.exe) A PEM certificate is a base64 (ASCII) encoded block of data encapsulated between. Syntax and content are defined by X.509 v3 standards for digital certificates, defined in IETF RFC 5280 specifications. PEM is a widely used encoding format for security certificates. We start by generating a certificate in PEM format, once the certs have been created we can create an HTTP or HTTPS or EXE payload for it and give it the path of PEM format certificate to be used to validate the connection.Īfter that again another prompt will open in which you would be asked to mention the domain name, here the SSL certificate will generate for To have the connection validated we need to tell the payload what certificate the handler will be used 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 it downloaded run the program file and follow the given below steps.Ī prompt will open in which you have to choose the option for building certificate from the given screenshot you can read I had chosen to impersonate domain. Open the terminal in your Kali Linux and type following to download it.
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. If the server certificate is signed by a CA that the firewall trusts, the firewall generates a duplicate of the server certificate signed by the Forward Trust certificate and forward the certificate to the client to authenticate.
The server sends a certificate for the client that is captured by the firewall. When the client begins with an SSL session with the server, the firewall captures the client SSL request and forwards the SSL request to the server. The firewall spoof the network traffic and verifies trust certificates to establish connection itself as a trusted third party to the session between the client and the server.
Through this article, you can learn how an attacker would able to generate an SSL certificate for any exe or bat file payloads so that he might be able to establish a connection with the host through the meterpreter session.
