EXCEL-vba工程密码破解

1、EXCEL vba工程密码破解这种方法实际是避开VBA工程密码验证，即，骗vba编辑器，该密码输入成功，请求放行。原理不多说了，先将方法公布：=1.新建一个工作簿，打开，按ALT+F11，进入vba代码编辑器窗口：2.新建一个模块，“插入”-“模块”把以下代码复制进模块并保存-Option ExplicitPrivate Declare Sub MoveMemory Lib "kernel32" Alias "RtlMoveMemory" _        (Destination As Long, Source

2、As Long, ByVal Length As Long)Private Declare Function VirtualProtect Lib "kernel32" (lpAddress As Long, _        ByVal dwSize As Long, ByVal flNewProtect As Long, lpflOldProtect As Long) As Long        Private Declare Function GetModuleHandleA

3、Lib "kernel32" (ByVal lpModuleName As String) As Long   Private Declare Function GetProcAddress Lib "kernel32" (ByVal hModule As Long, _        ByVal lpProcName As String) As Long   Private Declare Function DialogBoxParam Lib "user32&q

4、uot; Alias "DialogBoxParamA" (ByVal hInstance As Long, _        ByVal pTemplateName As Long, ByVal hWndParent As Long, _        ByVal lpDialogFunc As Long, ByVal dwInitParam As Long) As Integer        Dim HookBytes(0 To 5) As

5、 ByteDim OriginBytes(0 To 5) As ByteDim pFunc As LongDim Flag As BooleanPrivate Function GetPtr(ByVal Value As Long) As Long    '获得函数的地址    GetPtr = ValueEnd FunctionPublic Sub RecoverBytes()    '若已经hook,则恢复原API开头的6字节,也就是恢复原来函数的功能    If Flag Then MoveM

6、emory ByVal pFunc, ByVal VarPtr(OriginBytes(0), 6End SubPublic Function Hook() As Boolean    Dim TmpBytes(0 To 5) As Byte    Dim p As Long    Dim OriginProtect As Long       Hook = False       'VBE6.dll调用DialogBoxParamA显示VB6IN

7、TL.dll资源中的第4070号对话框(就是输入密码的窗口)    '若DialogBoxParamA返回值非0,则VBE会认为密码正确,所以我们要hook DialogBoxParamA函数    pFunc = GetProcAddress(GetModuleHandleA("user32.dll"), "DialogBoxParamA")       '标准api hook过程之一: 修改内存属性,使其可写    If Virtual

8、Protect(ByVal pFunc, 6, &H40, OriginProtect) <> 0 Then        '标准api hook过程之二: 判断是否已经hook,看看API的第一个字节是否为&H68,        '若是则说明已经Hook        MoveMemory ByVal VarPtr(TmpBytes(0), ByVal pFunc, 6        If

9、 TmpBytes(0) <> &H68 Then            '标准api hook过程之三: 保存原函数开头字节,这里是6个字节,以备后面恢复            MoveMemory ByVal VarPtr(OriginBytes(0), ByVal pFunc, 6            '用AddressOf获取MyDialogBoxParam的地址

10、0;           '因为语法不允许写成p = AddressOf MyDialogBoxParam,这里我们写一个函数            'GetPtr,作用仅仅是返回AddressOf MyDialogBoxParam的值,从而实现将            'MyDialogBoxParam的地址付给p的目的           

11、 p = GetPtr(AddressOf MyDialogBoxParam)                        '标准api hook过程之四: 组装API入口的新代码            'HookBytes 组成如下汇编            'push MyDialogBoxParam的地址 

12、           'ret            '作用是跳转到MyDialogBoxParam函数            HookBytes(0) = &H68            MoveMemory ByVal VarPtr(HookBytes(1), ByVal VarPtr(p), 4      &

13、#160;     HookBytes(5) = &HC3                        '标准api hook过程之五: 用HookBytes的内容改写API前6个字节            MoveMemory ByVal pFunc, ByVal VarPtr(HookBytes(0), 6        &#

14、160;   '设置hook成功标志            Flag = True            Hook = True        End If    End IfEnd FunctionPrivate Function MyDialogBoxParam(ByVal hInstance As Long, _        ByVal pTempla

15、teName As Long, ByVal hWndParent As Long, _        ByVal lpDialogFunc As Long, ByVal dwInitParam As Long) As Integer    If pTemplateName = 4070 Then        '有程序调用DialogBoxParamA装入4070号对话框,这里我们直接返回1,让        'VBE以为密码正确了

16、0;       MyDialogBoxParam = 1    Else        '有程序调用DialogBoxParamA,但装入的不是4070号对话框,这里我们调用        'RecoverBytes函数恢复原来函数的功能,在进行原来的函数        RecoverBytes        MyDialogBoxParam = DialogBoxPa

17、ram(hInstance, pTemplateName, _                           hWndParent, lpDialogFunc, dwInitParam)        '原来的函数执行完毕,再次hook        Hook    End IfEnd Function-3.右击sheet1工作表，“查看代码”复制以下代码进去并保存：-sub 破解()if hook thenmsgbox "破解成功"end ifend subsub 恢复()RecoverBytesmsgbox "恢
