DroidSheep is an open-source Android hacking app made by Corsin Camichel that allows you to intercept unprotected web-browser sessions using WiFi. DroidSheep APK is software developed only for testing security vulnerabilities and it is not made for harming any person. It works on the Android platform and to use DroidSheep you need to have your device rooted. DroidSheep is bundled as an APK file, but if you want the source code, you can get it from the original author's Github repo. This is not managed by Corsin Carmichael and the content of this website should be used only as instructions.
When users interact over the WiFi, other parties in the transmission range can also secretly listen to the event. DroidSheep works by reading all of the packets between the sender and receiver. This is ideal for checking any security vulnerabilities on your side. The only solution to avoid this is by using HTTPS. If you already have an SSL certificate implemented on your website, thus you do not need to use DroidSheep to check vulnerabilities because you're already encrypted and protected.
As opposed to other network utilities, DroidSheep is simple to use and very reliable for testing purposes. This enables you to simulate a threat and find vulnerabilities in your current network, so you can easily diagnose the issues and implement proper methods to avoid threats.

To use DroidSheep for conducting tests, your device will require root permissions. If you do not have root permissions, then you cannot use this app. That's because, to work properly, DroidSheep requires Busybox to be installed on your device. Busybox provides your system with some additional and useful Linux commands.
When you implement an SSL certificate on your website, DroidSheep can still listen to your transmitting content, but DroidSheep cannot read the actual content because it is encrypted. Therefore, you have to decode it, to read the actual content. This is not practical and possible.
As of the time that I'm writing this guide, it doesn't work on Marshmallow. But I've used this successfully on Jellybeans and Kitkat and can confirm it's working.
When compared to other similar apps, DroidSheep is quite easy to use, but sometimes you might run into some problems when using DroidSheep. The most common issue is its incompatibility with newer versions of Android. The only solution to overcome this is to switch back to an older version of Android temporarily. You can use an old phone of yours for this.
