As technology continues to develop, the need to protect digital files becomes increasingly important. One example of this is protecting Excel files with passwords or other security measures. However, there may be instances where access to these protected files is necessary, whether it be for work or personal reasons. This article will explore methods for accessing and hacking protected Excel files, as well as tips for preventing unauthorized access to sensitive information.
How to Access Protected Excel Files
If you find yourself in a situation where you need to access a protected Excel file but do not have the password, there are a few methods you can try.
Method 1: Use an Online Tool
There are several online tools available that claim to be able to crack Excel passwords. One example is Password-Find, which offers a free trial for their services. Simply upload the protected file to their website and wait for the password to be cracked.
Method 2: Use a Macro
If the Excel file is not heavily protected, it may be possible to use a macro to bypass the password. To do this, open the protected file and press Alt + F11 to open Visual Basic. Select Insert > Module, then paste the following code:
Sub PasswordBreaker()
‘Breaks worksheet password protection.
Dim i As Integer, j As Integer, k As Integer
Dim l As Integer, m As Integer, n As Integer
Dim i1 As Integer, i2 As Integer, i3 As Integer
Dim i4 As Integer, i5 As Integer, i6 As Integer
On Error Resume Next
For i = 65 To 66: For j = 65 To 66: For k = 65 To 66
For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66
For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66
For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126
ActiveSheet.Unprotect Chr(i) & Chr(j) & Chr(k) & _
Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) _
& Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
If ActiveSheet.ProtectContents = False Then
MsgBox “One usable password is ” & Chr(i) & Chr(j) & _
Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
Exit Sub
End If
Next: Next: Next: Next: Next: Next
Next: Next: Next: Next: Next: Next
End Sub
Press F5 to run the macro. If the password is successfully bypassed, a message box will appear with the password.
While it may be necessary to access protected Excel files, it is important to take measures to prevent unauthorized access to sensitive information. Here are a few tips:
Use a Strong Password
When protecting an Excel file with a password, use a strong password that is difficult to guess. Avoid using common phrases or easily obtainable personal information such as birth dates or names.
Limit Access to Sensitive Information
If possible, limit access to sensitive information to only those who need it. This can be done by assigning different levels of permissions to users or groups within the organization.
Regularly Change Passwords
Regularly changing passwords can help prevent unauthorized access to sensitive information. Consider implementing a policy that requires passwords to be updated on a regular basis.
Encrypt Files
Encrypting files is a more secure method of protecting sensitive information. This method makes it more difficult for unauthorized users to access the information, even if they manage to bypass password protection.
FAQ
