Introduction:Front-end code is a direct burst in the browser, many web attacks are directly debug business logic to find vulnerabilities to attack, in addition to some like "for nothing" molecular violence to steal other people's web page simple modification to profit, overall is the front-end logic is too easy to read, This article mainly based on JavaScript obfuscator introduce the basic idea of front-end confusion.First, JavaScript obfuscator introduction:JavaScript Obfuscator is a JS

Procedure: Right-click the project, select Properties, find the signature tab, create a signature file, and enter the password. after the project is released, the DLL and exe files will be confused.

This article is about how to invoke C (c + +)-written DLLs in a C # environment. "Reprint marked the source." First, the preferred creation of a C DLL project, production DLL files used for standby, steps are as follows: 1, VS2010 create C + + Project Select Win32 Application, the name is Createcdll, in the application settings interface to select the DLL, the fo

. NET development tools, such as ilspy, can be easily decompiled to view the source code. To protect your own software, the software is generally encrypted, not only internal key data is encrypted, after the software is developed, the software is encrypted to prevent others from easily decompiling and viewing important data. I tried the obfuscation of reactor and the encrypted DLL and exe, after it is easy

The jar package needs to be confused recently and there are many pits for the first time the jar is confused. First said the hole encountered, before using Eclipse packaging jar is very convenient, has not been replaced. After exporting using the Android SDK with the Proguardgui obfuscation (directory \sdk\tools\proguard\bin\proguardgui.bat) use the process online quite a lot. But because Proguardgui does not support jdk8 under the Rt.jar. Only to fin

In the Java language programming, you can reverse-engineer to get the Java program source code, this anti-compilation tool has Jad, Dex2jar, Jdec, Dedexer and so on. Therefore, in order to protect the fruits of our labor, as far as possible to t

Java-written code is very easy to decompile, but you can use Proguard to do your best to protect our code, Proguard specific use can refer to the official documentation (http://proguard.sourceforge.net/), Write down my configuration now (in actual use) for reference 1. Download Proguard to http://proguard.sourceforge.net/2. Ready to have the jar bag, I'm here for example is Yulore_yellowsdk.jar3.

reason to see codeproject above an article explaining how to apply mono.cecil to implement. NET code injection, which caught my attention all of a sudden. Unlike our usual reflection, it implements the code to directly modify the assembly, which is much more advanced than the 16 binary tool to modify the Exe/dll binary file, after all it is original. NET code, you can directly debug, observe the implementation process. Take care, find systeminternal

There are new technologies such as Hibernate, Spring, and so on, which are managed by a configuration file, and when we use the obfuscation, only the Java files are confused, and it's bound to cause Java confusion, The information in the configuration file cannot correspond to the class name and method name inside Java, so when confusing, you must point out that those files are not involved in confusion.
