You can simply collect every detail about surrounding WiFi networks from one place and study their security, signal strength, noise, and configuration.īy combining these two methods, you can effortlessly select the optimal place for a WiFi router, set up a large enterprise WiFi network, or eliminate dead spots that are preventing you from fully enjoying your internet connection. If all you want to do is learn more information about other WiFi networks in your general area, you don’t have to go anywhere. This is easily done with WiFi analyzer iPad or iPhone apps because you can just walk from one place to the next and instantly see where your WiFi network leaves something to be desired. When analyzing your own WiFi network, you probably want to know where its coverage ends and uncover all areas of signal weakness, also known as dead spots. There is also a wide range of tools such as NetworkMiner available to view and analyze packet captures generated from app trafficĭo you have any successes or failures grabbing packet captures from iOS devices? Please share in the comments.You can use a WiFi analyzer in two different ways: to analyze your own WiFi network or to analyze other WiFi networks. The effectiveness of these techniques can be limited but it is much safer to get packet captures compared to jailbreaking devices, and is fully supported by Apple. This works because the initial connection to encrypted websites is not immediately encrypted and the will often provide some basic information such as the host and URL and the certificate issuer Review all HTTPs connections and extract the host information listed in the certificate x.509 certificate.Signing in with different accounts, clicking buttons that are not usually hit, and closing and re-opening over and over can sometimes show otherwise hidden usage of APIs or connections to third parties.

DNS requests are almost never encrypted and contain a lot details regarding what hosts your device is connecting to.

The app making HTTP connections will usually indicate some sort of older functionality. These should stand out because newer versions of iOS apps almost always use encryption.

Review all HTTP requests sent by using the app.

There are several techniques that can be used to analyze the security of applications using packet captures, including identifying apps infected with malware or undocumented spyware-like functionality. Actually running the app while getting logging the packets is simple - run the app while Wireshark (or another sniffing utility) listens on the rvictl adapter on the Mac/ Apple fully supports running a packet capture on iOS devices assuming 1.) the phone trusts the device it is connecting to and 2.) an OS X machine running a packet sniffer is used.

There is an exception to these general restrictions. Due to numerous restrictions set up by Apple (check out EFF's review of the app rules) there are very few commercial tools that can be used to review iOS applications.Īlmost all of the non-commercial iOS application security tools have a not-really-that-legitimate feel, and if not used carefully or by technical security folks could result in data loss. Reviewing the security of iOS applications can be difficult.
