If the data sent is just strings then it’s very simple to just replace text or attempt modification to the request. This will be very similar to intercepting HTTP traffic with Burp. Manual Intercept TrafficĬlicking on the TCP Intercept Tab will allow to enable and disable Manual Intercepting. In addition, if Burp crashes or you close Burp without saving the TCP History it will still be automatically loaded when you start Burp. The database can be exported or imported from the Server Configuration Tab. All your traffic will be logged into the TCP History Tab and stored locally in a sqlite database. Once the proxy is started you can intercept it in real time. The proxy does not start until ‘enable’ is checked in the table. Then you can check the SSL check box before adding the proxy. If the service is using SSL then you need to export Burp’s CA cert to the same folder that Burp is running out of for the extension to find it and generate certs that will pass certificate verification. Once you know the right host name and port you can configure these settings as shown above. You could also run wireshark but Nope will filter this information for you. You can switch to the ‘DNS History’ Tab to view the DNS queries and ports that are trying to connect to you. This requires that you know the hostname and Port the application is trying to connect. To perform normal intercepting of binary traffic of applications you can set the DNS IP address to the extension’s IP address and then create a Listener Under ‘Server Config’. Code Playground allows you to create a custom python payload based on the request currently displayed in the repeater.TCP repeater can be used to replay requests to the client or server on the currently connected socket streams.Python Code can be used instead of the normal Match and Replace Rules for more advancing mangling of requests and responses.Just like the normal Burp proxy but with binary streams. Manual Interception binary protocols and change them before sending them back to the server or client.Match and replace rules support both hex and string replacement.(Client to Server, Server to Client, or Both. Automatic Match and Replace Rules that are customizable based on the direction of traffic.All requests and responses are saved to a sqlite database and can be exported or imported into the tool.This TCP proxy has several features built in. This combined with the DNS history can help you find which hosts and ports a mobile app or thin client is attempting to contact so that you can create interceptors for this traffic and proxy it to the real servers. Nope Proxy has a port monitor that will only display tcp ports that a remote client is attempting to connect on. If this box is not checked then the extension will resolve the Real IP address unless it has been overridden in the ‘Custom Hosts File’ Port Monitoring If the ‘Use DNS Response IP’ checkbos is checked (default) then the extension will resolve all hosts not in the Custom hosts file to which ever IP address is set in the ‘DNS Response IP’ input box. The Custom Hosts File is not related at all to your normal hosts file and will over ride it. The server will need to be restarted for this change to take effect. Changing the interface number will automatically change the IP address. The DNS server automatically starts with the IP address of the last interface you set in the Interface input box. It can also be confgured to send all requests to the real IP unless specified in the custom hosts file. You can configure it to send all traffic to the same IP address as Burp or you can use a Custom Hosts File to configure only some hosts to be forward to Burp while others can be forwarded to other hosts. The DNS server configuration allows granular control over your DNS settings. It also provides the ability to automatically match and replace hex or strings as they pass through the proxy or you can use custom python code to manipulate the traffic. It also uses Burp's CA cert so that if the browser or mobile device is already configured to access SSL/TLS requests using this cert then the encrypted binary protocols will be able to connect without generating errors too. This extension allows you to create multiple listening ports that can MiTM server side services. You need to create invisible proxy listeners in BurpSuite for the Burp to intercept HTTP traffic or you can use the second feature of this extension to intercept binary/non-http protocols. It makes it easier to send mobile or thick client traffic to Burp. This will route all DNS requests to Burp or preconfigured hosts. This Burp extension adds two new features to BurpSuite. This project is a Burp extension that can proxy and modify TCP and DNS traffic.
