Other ways to take screenshots on mobile phones
Those who are familiar with Android should be familiar with adb. It allows developers to use this command-line tool to interact with their mobile phones. The permissions of adb are higher than ordinary mobile phone applications. Using adb tool, we can install or uninstall mobile phones. The software can back up or restore the data in the phone, take screenshots, etc.
However, in the Android system, the API interface or corresponding permissions for screenshots are not provided for general apps. So what if an application needs to implement the function of taking screenshots on mobile phones? The answer is to use adb proxy. The adb proxy is actually a native executable program developed by developers. It has the same functions and permissions as adb. Apps that want to implement screen capture use the adb proxy to access Android system resources, including data in FrameBuffer. Screenshots can be obtained from FrameBuffer. The user installation method is also very simple, download the app at the same time will get an adb proxy program, the user can use adb to install the program into the mobile phone through the computer.
The screen capture app communicates with the adb agent program in the phone through a socket. If there is a spy app in the phone, it can also communicate with the adb agent program through the same port number. In other words, if the spy app knows the port number that the screenshot app communicates with the adb proxy, then the spy app can access the screenshot of the phone without the user's knowledge.
A new privacy disclosure method was born, but how to use this vulnerability to obtain more private information more secretly? We know that mobile phone screenshots often occupy a relatively large storage space, especially if the attacker must also upload the screenshots to the server. If you don't know whether the pictures have use value, you need to upload more pictures to the server, and then the server will determine which pictures have use value. In this way, the app will consume a lot of memory and Internet traffic, which is easy to be discovered by users. On the other hand, if the image recognition function is added to the mobile phone, it will also consume a lot of CPU usage time, and it is easy to be found by users. The following method can be used to solve this problem.
- First, create a database of commonly used screenshot apps, and one app corresponds to a socket port number. The monitoring program first uses PackageManager to list all programs in the system in the mobile phone to determine whether the mobile phone is installed with a screenshot app, and to determine the port number of the adb agent in the mobile phone according to the package name.
- Detect whether the app to be attacked is running. The app to be attacked here mainly refers to the address book or social app, so that the user's private data can be stolen. The detection method is mainly to read the information in the /proc/[PID]/stat field , Judge whether the target app is running through the change of the running time of the cpu.
- Determine which activity the app to be attacked is in. Since the title bar of most activities in an app is different, the title bar of the activity can be used as the identification. At this time, the screen capture function must be used, that is, read only after the screenshot. Take the pixel value of the title bar to determine which interface the app is on at this time.
- Next, it loops to detect the input status of the mobile phone keyboard, that is, to use a screenshot to determine which button the user is clicking. Each time the user clicks a button, the app only reads the pixel value in the area, and then calculates the hash value based on the read pixel value and determines which button the user clicked. Similarly, by reading the pixel value of ↑, you can also determine whether it is a capital letter or a number. And the reading speed of five times a second exceeds the typing speed of most people, so all the actions of the user clicking the button can be read.
- The user name or password is determined according to the letter or number sequence of the user clicking the button, thereby obtaining user privacy.
