It also gives cybersecurity professionals and cybercrime forensic investigators the ability to trace network connections. Wireshark can be used to troubleshoot networks with connection and performance issues. ![]() This small tweak can be used to overcome the problem of proxying non-trivial iOS application traffic.Wireshark was first developed in 1998 and known under the name Ethereal-its name changed to Wireshark in 2006, almost 10 years after. Type “exploit” in the Metasploit console and you will see the application traffic been proxied for non-standard ports in burp.(this is the normal setting to proxy standard HTTP traffic)įig 4: Configure IP and DNS forwarding settings in the IOS device. Set HTTP Proxy to the IP address of the laptop and corresponding port in burp.Click settings ‘ Wi-Fi ‘Click on hotspot ‘ DHCP and set DNS = (IP of Laptop).In other words, every port will require a separate Proxy listener to be configured in burp.įig 3: Configure incoming listener and redirect the iDevice traffic to appropriate IP and port to Server. Click ok and repeat the above steps for all the ports that the iOS application is explicitly sending HTTP application traffic to.Click force use of SSL if the outgoing traffic is sent using https.Request Handling ‘ Redirect to port: (Enter the corresponding port number).Click Request Handling’ Redirect to host: (Enter the domain name of the server).Go to Proxy’Options’Add set ‘bind port’ to the port where the traffic needs to be sent (note: this is the non-standard tcp port number recorded in Wireshark).Configure Burp to listen on specific ports for the incoming traffic from iDevice and forward it to the appropriate port as follows:.set targethost = (IP address of laptop which is running the hotspot)įig 2: Configuring DNS server on the laptop using fakedns module in Metasploit.set SRVPORT = 53, set TARGETACTION = BYPASS, set TARGETDOMAIN = (Note: by setting TARGETDOMAIN= all the traffic except the traffic coming from will be spoofed).set SRVHOST = (IP address of laptop which is running the hotspot). ![]() Start the Metasploit console to perform DNS spoofing and enter the following commands.Note the port number where the traffic is being sent.įig 1: Finding the non-standard port number where application sends Traffic.Filter the traffic to look at the traffic going to the destination server IP (ip.dst= ip.ip.ip.ip).Start a network sniffer (like Wireshark) and look for traffic going to any non-standard ports.Create a wireless hot spot with your machine and connect the iDevice to the hotspot.Given below is a step by step approach to intercept Native Web Socket iOS application traffic. Start a proxy on the laptop to intercept traffic all traffic from iDevice after DNS spoofing.Spoof the DNS for the iDevice to send all data to laptop.Sniff traffic using Wireshark to find out the port and IP of the webserver.The blog is divided into three main steps. We can perform DNS spoofing to forward all the HTTP traffic for all of the ports through a MitM proxy like Burp. There is a workaround to fix this problem. For more technical details of how websockets in native iOS can be configured, check out this elabs blog post. ![]() One of the reasons that the normal proxying method might be failing is because it might be using some native websockets to interact with the web server instead of the normal UIWebView class. This application traffic could not be proxied by changing the iOS manual proxy settings located at (Settings -> Wi-Fi -> HTTP Proxy -> Manual) and forwarding the iDevice traffic to the proxy. The blog will help penetration testers who are trying to intercept sensitive data that is being sent by an iOS application in a non-trivial manner over the network because some applications do not respect the iOS proxy settings.ĭuring a recent iOS application penetration test, I encountered an iOS application that was sending data to port 20xx on a web server. In this blog, we will go through proxying an iOS application which uses native web sockets to interact with a web server.
