trojan binder

Prefacebefore we have learned the virus-free technology to kill the signature code, but Trojan people are not feeling or very mysterious, then let me for you to uncover the mystery of the Trojan Horse. first, the basic knowledge1.1. Trojan virusTrojan Horse (Trojan) the name is derived from the ancient Greek legend (th

First, let's take a look at the sequence chart for running the android binder system: (This figure is from Google Search) From the time sequence diagram, the entire android binder system is still somewhat complicated, but careful analysis may find that the operating mechanism of the entire android binder seems to be similar to a common system architectu

In this article, we will thoroughly analyze how to register a service with the system. In the example in the first article, exampleservice registers a service with the system using the following statement. // File: exampleservice. cpp In the previous article, we know that the reference of the servicemanager proxy object of the current process can be obtained by calling the defaultservicemanager () global function. Before in-depth analysis of the addservice () method, let's take a look at how s

Binder: a paper clip or paper clip. We often use pins to separate two sheets of paper. In the Android system, binder is the basic framework used to complete inter-process communication IPC, that is to say, different processes are separated so that each process can transmit messages to each other. If you have developed a Java server, you can also think of it as an RPC call, that is, directly calling function

1. What is binder? Intuitively, Binder is a class in Android that inherits the IBinder interface From the perspective of IPC (inter-process communication, interprocess communication), Binder is a cross-process communication in Android, and Binder can be understood as a virtual physical device whose device driv

Binder proxy technical solution Author's low-end coders Time: 0x0 Several friends tried to hook the ioctl of system_process to intercept the IPC communication of the system. The disadvantage of this solution is that it is too low-layer. After successful interception, it is quite troublesome to parse the communication data. in addition, there are also a bunch of compatibility issues. Due to different Android firmware versions, some parcelable structure

There's a bunch of online Binder the principles of the article, are very long, I hope I can try to put this question briefly. 1) About Binder DriveBinderin theAndroidwas designed as a driver, installed in/dev/binder, which isAndroidand theLinuxone of the important differences:Androida new inter-process communication method is proposed (IPC). In addition, this app

Analysis of the Binder-based IPC process framework in Android, androidbinder Preface: Activity, Service, BroadcastReceiver, and Content Provider are four application components of Android. These components that constitute a complete application can be in the same process or not in the same process, when these components are not in the same Process and data interaction is required, an Inter-Process Communication mechanism (IPC) is required, the

I believe that friends who often play Trojan horse will know the characteristics of some Trojans, but also have their favorite Trojan, however, many friends still do not know the rise of recent years, "DLL Trojan" why things. What is a "DLL"? What's the difference between it and a typical Trojan? First, from the DLL te

1. Mediapplayerservice start, how to register in ServiceManager, do not explain the detailed detailsServiceManager is the service manager of the entire system, and the rest of the system services are called ServiceManager through the Defaultservicemanager remote interface. After the service obtains the ServiceManager interface, it joins itself to the ServiceManager, then initiates itself and waits for the client to connect to the request.The knowledge about how Systemmanager starts and becomes a

AsInterface parsing in Binder, binderasinterface When AIDL is used for communication, an asInterface function is generated in Stub class. The example in Android development art exploration is analyzed. The source code of the asInterface function is: 1 /** 2 * Cast an IBinder object into an com.willhua.demoaidl.aidl.IBookManager 3 * interface, generating a proxy if needed. 4 */ 5 public static com.willhua.dem

Read a lot of articles on the internet on binder, but I still want to record their own mental journey, some are following the footsteps of others to appreciate the steep scenery, some of their own alone into the code deep salvage of the harvest. I'm not sure I'm all over it, but I'm more worried about the way I'm going to be at a two-month time. The best way to verify and retain them is to write them down and read them back in a few months to see if t

model receives parameter issuesThe general answer is the solution I said above, which seems to be not what I want.Try to think for a moment.The standard HTTP request is received when, for MVC, he is just a form or a querystring (if you understand the error, please correct), then how does the MVC framework do to bind a form to a model?Why did the corresponding field in HttpContext.Request.Form complete the string concatenation?Why is the assignment of the form and the model different? Can I use

Trojan horses often go into your system when you don't notice, and this article introduces some of the places where they often hide. After reading this article, that you are not a master you can easily clear the system in the Trojan horse program. 1, integrated into the program In fact Trojan is also a server-client program, in order not to allow users to easily

ServiceManager, in fact, is also a service, but its server-side implementation does not use the binder library structure implementation, but directly open Binder/dev for communication, not universal.The following is an example of Mediaplayservice in MediaServer, which illustrates the more common implementation of a service using binder communication mechanisms.Fi
