  • 穿目前所有还原下载者 C 源码
    说明:  [C/C++] 穿目前所有还原的下载者 C++源码 下载者包括四个工程: CDown:生成器 userinit:真正的下载者 Dat:驱动和下载者的安装程序 pass:驱动程序 原理:驱动程序可以穿透还原卡,并且可以修改系统文件,这里是通过修改系统文件userinit.exe来实现的。userinit.exe的功能很简单,就是启动explorer.exe。这里就是通过替换uerinit.exe,伪造一个userinit.exe。这个伪造的程序可以实现uerinit.exe的原始功能,并可以实现自定义的功能,比如下载执行,发送数据。 驱动的功能就是替换指定的系统文件。 将userinit Dat pass 编译出来的文件放到cdown的res里,再生成出生成器就可以使用它生成下载者,也就是这个穿还原的程序([C/C++] wear all current restore downloader C++ source code The download includes four projects: CDown: generator Userinit: a true Downloader Dat: driver and downloader installer Pass: Driver Principle: driver can penetrate the restore card, and you can modify the system file, here is through the modification of system file userinit.exe to achieve. The function of userinit.exe is simple, that is, to start explorer.exe. This is where you forge a userinit.exe by replacing uerinit.exe. This fake program can realize the original function of uerinit.exe, and can implement custom functions, such as downloading, executing and sending data. The driver's function is to replace the specified system files. The userinit Dat pass compiled files into the Cdown res, regeneration into the generator, you can use it to generate the download, that is, the process of wearing a restore)
