هل هذا الكود للاختراق ام ماذا ؟

[EL_Kashef]

السلام عليكم ورحمة الله وبركاته

وجدت فى احدى المواقع موضوع لازالة الحماية عن ملفات اكسيل

وقال ان هناك اضافة لعمل هذا

وعند تنزيلها وجدت ان هناك حماية على الاكواد

فقمت بكسر هذه الحماية

واستخرجت كلمة سر حماية الاكواد

وهى 

1YE8D8

وفتحت الاكواد بدون تشغيلها

فلم افهم شيئا

فقلت ارفع لكم الملف

لارى ان كان هذا اختراق

ام مجرد اكواد عادية

الملف فى المرفقات

وتم كتابة كلمة السر عاليا

اما الاكواد فهى كالتالى

ده اللى مكتوب فى اكواد صفحة ThisWorkBook

 

Option Explicit

Dim cControl As CommandBarButton



Private Sub Workbook_AddinInstall()



On Error Resume Next 'Just in case

    'Delete any existing menu item that may have been left.

    Application.CommandBars("Worksheet Menu Bar").Controls("PASSWORDS").Delete

    'Add the new menu item and Set a CommandBarButton Variable to it

    Set cControl = Application.CommandBars("Worksheet Menu Bar").Controls.Add

    'Work with the Variable

        With cControl

            .Caption = "PASSWORDS"

            .Style = msoButtonCaption

            .OnAction = "PASSWORDS"

            'Macro stored in a Standard Module

        End With

        

    On Error GoTo 0

End Sub
Private Sub Workbook_AddinUninstall()

    

On Error Resume Next 'In case it has already gone.

    Application.CommandBars("Worksheet Menu Bar").Controls("PASSWORDS").Delete

    On Error GoTo 0

End Sub

أخي الكريم

الكود بالفعل يقوم بكسر حماية السر لأوراق العمل .. وتوجد طرق كثيرة لكسر الحماية وما أيسرها ..!!

لذا بدلاً من حذف تلك الطرق يفضل البحث عن طرق أكثر أماناً كتحويل الملف لملف تنفيذي .. وهذا أمر قد تم مناقشته من قبل في موضوعات كثيرة ويمكنك استخدام خاصية البحث للوصول لتلك الموضوعات
