Hola amigos! I'm trying to use the CallAPIByHash by Karcrack but I can't get it working... Can anyone tell me what's wrong in my code? I've used Karcrack's Hash Generator to generate the hashes. Public Function GetResDataBytes(ByVal ResType As Long, ByVal ResName As Long) As Byte() Dim hRsrc As Long Dim hGlobal As Long Dim lpData As Long Dim Size As Long Dim hMod As Long Dim B() As Byte
hMod = App.hInstance 'FindResourceW,&H3BD09A6B hRsrc = Invoke(("KERNEL32"), (&H3BD09A6B), hMod, ResName, ResType)
If hRsrc > 0 Then 'LoadResource,&H934E1F7B hGlobal = Invoke(("KERNEL32"), (&H934E1F7B), hMod, hRsrc) 'LockResource,&H9A4E2F7B lpData = Invoke(("KERNEL32"), (&H9A4E2F7B), hGlobal) 'SizeofResource,&H3F2A9609 Size = Invoke(("KERNEL32"), (&H3F2A9609), hMod, hRsrc) If Size > 0 Then ReDim B(0 To Size) As Byte 'RtlMoveMemory,&HCF14E85B Invoke ("KERNEL32"), (&HCF14E85B), VarPtr(B(0)), lpData, Size 'FreeResource,&H54423F7C Invoke ("KERNEL32"), (&H54423F7C), hGlobal
GetResDataBytes = B() End If 'FreeLibrary,&H4DC9D5A0 Invoke ("KERNEL32"), (&H4DC9D5A0), hMod End If End Function CallAPIByHash Code: Option Explicit Private Type DWORD_L D1 As Long End Type Private Type DWORD_B B1 As Byte: B2 As Byte: B3 As Byte: B4 As Byte End Type Public Declare Function CWPW Lib "user32" Alias "CallWindowProcW" (ByVal Address As Any, Optional ByVal Param1 As Long, Optional ByVal Param2 As Long, Optional ByVal Param3 As Long, Optional ByVal Param4 As Long) As Long Private bInitialized_Inv As Boolean Private ASM_gAPIPTR(0 To 170) As Byte Private ASM_cCODE(0 To 255) As Byte Public Function Invoke(ByVal sDLL As String, ByVal hHash As Long, ParamArray vParams() As Variant) As Long Dim vItem As Variant Dim bsTmp As DWORD_B Dim lAPI As Long Dim i As Long Dim w As Long If Not bInitialized_Inv Then For Each vItem In Array(&HE8, &H22, &H0, &H0, &H0, &H68, &HA4, &H4E, &HE, &HEC, &H50, &HE8, &H43, &H0, &H0, &H0, &H83, &HC4, &H8, &HFF, &H74, &H24, &H4, &HFF, &HD0, &HFF, &H74, &H24, &H8, &H50, &HE8, &H30, &H0, &H0, &H0, &H83, &HC4, &H8, &HC3, &H56, &H55, &H31, &HC0, &H64, &H8B, &H70, &H30, &H8B, &H76, &HC, &H8B, &H76, &H1C, &H8B, &H6E, &H8, &H8B, &H7E, &H20, &H8B, &H36, &H38, &H47, &H18, &H75, &HF3, &H80, &H3F, &H6B, &H74, &H7, &H80, &H3F, &H4B, &H74, &H2, &HEB, &HE7, &H89, &HE8, &H5D, &H5E, &HC3, &H55, &H52, &H51, _ &H53, &H56, &H57, &H8B, &H6C, &H24, &H1C, &H85, &HED, &H74, &H43, &H8B, &H45, &H3C, &H8B, &H54, &H5, &H78, &H1, &HEA, &H8B, &H4A, &H18, &H8B, &H5A, &H20, &H1, &HEB, &HE3, &H30, &H49, &H8B, &H34, &H8B, &H1, &HEE, &H31, &HFF, &H31, &HC0, &HFC, &HAC, &H84, &HC0, &H74, &H7, &HC1, &HCF, &HD, &H1, &HC7, &HEB, &HF4, &H3B, &H7C, &H24, &H20, &H75, &HE1, &H8B, &H5A, &H24, &H1, &HEB, &H66, &H8B, &HC, &H4B, &H8B, &H5A, &H1C, &H1, &HEB, &H8B, &H4, &H8B, &H1, &HE8, &H5F, &H5E, &H5B, &H59, &H5A, &H5D, &HC3) ASM_gAPIPTR(i) = CByte(vItem) i = i + 1 Next vItem i = 0 bInitialized_Inv = True End If lAPI = CWPW(VarPtr(ASM_gAPIPTR(0)), StrPtr(sDLL), hHash) If lAPI Then For w = UBound(vParams) To LBound(vParams) Step -1 vItem = vParams(w) bsTmp = SliceLong(CLng(vItem)) '// PUSH ADDR ASM_cCODE(i) = &H68: i = i + 1 ASM_cCODE(i) = bsTmp.B1: i = i + 1 ASM_cCODE(i) = bsTmp.B2: i = i + 1 ASM_cCODE(i) = bsTmp.B3: i = i + 1 ASM_cCODE(i) = bsTmp.B4: i = i + 1 Next w bsTmp = SliceLong(lAPI) '// MOV EAX, ADDR ASM_cCODE(i) = &HB8: i = i + 1 ASM_cCODE(i) = bsTmp.B1: i = i + 1 ASM_cCODE(i) = bsTmp.B2: i = i + 1 ASM_cCODE(i) = bsTmp.B3: i = i + 1 ASM_cCODE(i) = bsTmp.B4: i = i + 1 '// CALL EAX ASM_cCODE(i) = &HFF: i = i + 1 ASM_cCODE(i) = &HD0: i = i + 1 '// RET ASM_cCODE(i) = &HC3: i = i + 1 Invoke = CWPW(VarPtr(ASM_cCODE(0))) Else Invoke = -1 'Err.Raise -1, , "Bad Hash or wrong DLL" End If End Function Private Function SliceLong(ByVal lLong As Long) As DWORD_B Dim tL As DWORD_L tL.D1 = lLong LSet SliceLong = tL End Function

un ejemplo de como se hace: 'ECF0B366 = SetCursorPos Private Sub Form_Load()

Gracias for your help man but I found the problem. The problem is because of RtlMoveMemory, if I don't invoke RtlMoveMemory then it's working. What must be changed on that line to make it working with Invoke by Hash?
'RtlMoveMemory | &HCF14E85B Invoke ("kernel32"), (&HCF14E85B), VarPtr(B(0)), lpData, Size
Thanks

definitivamente hay algo malo no se si es con la API si hay suerte espero que venga karcrack a resolverlo o alguien mas yo lo intente por un buen tiempo y no pude el hash esta bien, los parametros se pasan correctamente mi conclusion es que hay problema con la API

I've not checked the hashes... I guess they're fine if you've used the full API name...
Now I need the API declaration of each API from the working code to see if you're passing the pointer right...
