ARK之进程枚举
A.进程1.CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS) /Process32First / Process32Next
void main()
{
HANDLE hSnap = CreateToolhelp32Snapshot( TH32CS_SNAPPROCESS, 0 );
if( hSnap == INVALID_HANDLE_VALUE )
{
cout<<"Create Toolhelp false"<<endl;
return;
}
PROCESSENTRY32 pEntry32 = {0};
pEntry32.dwSize = sizeof(PROCESSENTRY32);
bool bRes = Process32First( hSnap, &pEntry32 );
int pNums = 0;
while( bRes )
{
pNums++;
cout<<"PID:"<<pEntry32.th32ProcessID<<"\t"<<"Path:"<<pEntry32.szExeFile<<endl;
bRes = Process32Next( hSnap, &pEntry32 );
}
CloseHandle( hSnap );
cout<<"Process Nums:"<<pNums<<endl;
}
2.PsApi EnumProcess
DWORD dProcessIds = {0};
DWORD dRet = 0;
DWORD dRes = 0;
dRes = EnumProcesses( dProcessIds, sizeof(dProcessIds), &dRet );
if( dRes == 0 )
{
cout<<"EnumProcesses1 False"<<endl;
return;
}
int ProcessNums = dRet/sizeof(DWORD);
for( int i = 0; i < ProcessNums; i++ )
GetProcessPathById( dProcessIds );
cout<<"Process Nums:"<<ProcessNums<<endl;
3.ZwQuerySystemInformation(SystemProcessesAndThreadsInformation)5号 和16号功能SystemProcessesAndThreadsInformation
代码是R0的 但R3也可以使用
5号功能:
NTSTATUS Status = STATUS_SUCCESS;
NtQuerySystemInformation( 5, pBuff, 0, &uRet );
pBuff = (PCHAR)ExAllocatePool( NonPagedPool, uRet );
pTemp = pBuff;
Status = NtQuerySystemInformation( 5, pBuff, uRet, NULL );
if( NT_SUCCESS(Status) )
{
while( 1 )
{
PSYSTEM_PROCESS_INFORMATION pSystemProcessInfo = (PSYSTEM_PROCESS_INFORMATION)pTemp;
RtlUnicodeStringToAnsiString( &ansi, &pSystemProcessInfo->ImageName, TRUE );
DbgPrint("PId:%d\t", pSystemProcessInfo->ProcessId);
DbgPrint("Path:%s\n", ansi.Buffer );
RtlFreeAnsiString( &ansi );
if( pSystemProcessInfo->NextEntryOffset == 0 )
break;
pTemp = pTemp+pSystemProcessInfo->NextEntryOffset;
}
}
16号功能：
void EnumProcessBy_16()
{
NTSTATUS Status = STATUS_SUCCESS;
PCHAR pBuff = NULL;
ULONG uNums = 0;
ULONG uRet = 0;
PSYSTEM_HANDLE_INFORMATION_EX pSystemHandle = NULL;
pBuff = (PCHAR)ExAllocatePool( NonPagedPool, 100 );
Status = ZwQuerySystemInformation( 16, pBuff, 100, &uRet );
ExFreePool( pBuff );
pBuff = (PCHAR)ExAllocatePool( NonPagedPool, uRet );
Status = ZwQuerySystemInformation( 16, pBuff, uRet, NULL );
if( NT_SUCCESS(Status) )
{
ULONG index = 0;
LONG PId = -1;
pSystemHandle = (PSYSTEM_HANDLE_INFORMATION_EX)pBuff;
uNums = pSystemHandle->NumberOfHandles;
for(; index < uNums; index++ )
{
if( pSystemHandle->Information.ProcessId != PId )
{
PId = pSystemHandle->Information.ProcessId;
Display( pSystemHandle->Information.ProcessId );
}
}
}
else
{
DbgPrint("NtQuerySystemInformation False");
return;
}
4.EnumWindows / GetWindowThreadProcessId
只能枚举窗口进程
5.for(; ; ) OpenProcess 内核中也可以使用 通过PsLookupProcessByProcessId得到EPROCESS
//需提权
for( int i = 0; i <0xffff; i++ )
{
HANDLE hProcess = OpenProcess( PROCESS_ALL_ACCESS, false, i );
if( hProcess )
{
char ProcessName = {0};
GetProcessImageFileName( hProcess, ProcessName, MAX_PATH );
cout<<"PID:"<<i<<"\t"<<"Path:"<<ProcessName<<endl;
}
}
6.活动链 ActiveProcessList
硬编码了 也可以不用硬编码,可以通过在DriverEntry中使用PsGetCurrentProcess得到system的EPROCESS 然后向下搜索system字符串 搜到后减去EPROCESS BASE就得到了offset
void EnumProcess()
{
PEPROCESS pEprocess = NULL, pTemp = NULL;
pEprocess = PsGetCurrentProcess();
pTemp = pEprocess;
do
{
DbgPrint("PId:%d\t", *(PULONG)((ULONG)pTemp+0x084) );
DbgPrint("Path:%s\n", (PUCHAR)((ULONG)pTemp+0x174 ));
pTemp = (PEPROCESS)( (ULONG)(*(PULONG)((ULONG)pTemp+0x088)) - 0x088 );
} while ( pTemp != pEprocess );
}
7.R0 暴力搜索内存
这里设计搜索的内存大小,x86下 只要搜0x80000000~0xFFFFFFFF 也能很快跑完
但在x64下,内核的地址太大了
那如果搜0xfffffa800000000~0xfffffffffffffff这么大的内存,10分钟都搜不玩
我们可以在DriverEntry中获取system的EPROCESS PsGetCurrentProcess的EPROCESS 然后向上向下搜索2G空间 一般都能找到
另一个问题是EPROCESS的识别
一般PEB可以当做一个判断的地方
CreateTime
.....
还可以在EPROCESS向上搜 OBJECTTYPE的typeID 需要注意的是在win10中 这个typeid是随机固定值
假如有一个进程的typeid是10 那么其他进程的typeid也是10 但这个10是每次启动都不一样,那么我们需要先知道这个值
方法也是在DriverEntry中获得system的EPROCESS 想上找到typeid 即可
可以参考 搜索高端内存枚举进程 自行百度
void EnumProcess()
{
ULONG uStartAddr = 0x80000000;
PEPROCESS pCurrent = PsGetCurrentProcess();
DbgPrint("PId:%d\tPath:%s\n", *(PULONG)((ULONG)pCurrent+0x084), (PUCHAR)((ULONG)pCurrent+0x174));
for(; uStartAddr < (ULONG)pCurrent+0x800000; uStartAddr += 4 )
{
ULONG uRet = IsValidAddr( uStartAddr );
if( uRet == VALID_PAGE )
{
if( ( *(PULONG)uStartAddr & 0xffff0000) == 0x7ffd0000 )
{
if( IsRealProcess(uStartAddr - 0x1b0) )
{
PLARGE_INTEGER pExitTime = (PLARGE_INTEGER)(uStartAddr-0x1b0+0x078);
if( pExitTime->QuadPart == 0 )
{
DbgPrint("PId:%d\tPath:%s\n", *(PULONG)(uStartAddr-0x1b0+0x084), (PUCHAR)(uStartAddr-0x1b0+0x174));
}
uStartAddr -= 4;
uStartAddr += 0x25c;
}
}
}
else if( uRet == PDEINVALID )
{
uStartAddr -= 4;
uStartAddr += 0x400000;
}
else
{
uStartAddr -= 4;
uStartAddr += 0x1000;
}
}
}
8.PspCidTable 句柄表

uMax_Handle = pCidHandleTable->NextHandleNeedingPool;

}
}

}
}
}
}
}
break;
}

9.Inline Hook KiSwapContext
因为在x64下不能hook 就不写了
10.通过Csrss.exe枚举进程
显示获得Csrss.exe进程
需要注意不同系统中ObjectTypeNumber可能不同 这里21是Port object
Csrss.exe的特征是有一个符号\\Windows\\ApiPort
其实这个并不是真的通过Csrss.exe来枚举进程,而是通过EPROCESS下的HANDLE_TABLE下的TableCode来枚举的
真正是通过Csrss.exe枚举进程可以参考
