First, we need to request permission.

We need to add two entries in AndroidManifest.xml file as highlighted in the code below. ThatвЂ™s a perfect test bed for us to write a Cydia extension in a way that the app always returns true regardless of the user input.Д¬lass name: ДЄs shown in the Cydia Substrate documentation here, lets first set up our AndroidManifest.xml file. If the user entered credentials are matching, the app is returning a boolean value true and then redirecting the user to a private activity. If(ntentEquals(uname) & ntentEquals(pass))ДЄs you can see in the above code snippet, the app is getting the username and password from the user and then comparing it against the values stored in SharedPreferences. String pass=pref.getString(вЂњpasswordвЂќ,null) String uname=pref.getString(вЂњusernameвЂќ,null) Public boolean isValidLogin(String username, String password) Toast.makeText(getApplicationContext(), вЂњInvalid Username or passwordвЂќ, Toast.LENGTH_LONG).show()

Intent in=new Intent(getApplicationContext(),Welcome.class)

To keep the things simple, I am showing the original source as the idea here is to understand how to write Cydia Substrate extension assuming that we have access to the applicationвЂ™s logic.ДЇollowing is the code snippet for Login.java

We can decompile the APK and get the Java version of the code to understand the logic. Obviously, we first need to understand the applicationвЂ™s logic before proceeding with the Substrate extension. Our goal is to bypass this login by writing a Cydia Substrate extension. When the user enters invalid credentials, an error will be thrown as shown in the figure below. Following is our target appвЂ™s first activity. Like every other article of mine, we will have a vulnerable app here and then we will exploit it using this Cydia Substrate extension. Now, LetвЂ™s start writing the Substrate extension.

Target application вЂ“ you can download it here:.

Create a new Android Application (This is the Cydia Substrate extension) using your favorite IDE and add substrate-api.jar library into your libs folder.

Rooted Android Device with Cydia Substrate installed.
