When using Word for file protection, we often use formal protection (tools -> protection documents), which is most thorough in form.
Copy & Paste operations cannot be performed by households.
However, the vulnerability of the Word document released a few days ago allows you to remove this password with a very simple method.
Let's test it yourself:
First create a Word document, protect the document, tool -> Protection documentation -> Check "Allow in the documentation
Perform such editing "-> choose" Fill in the form ", one password box will pop up, enter 2 passwords (I choose 123 here as Word
The file password), so that the document has been protected.
Then we come to crack it, open the Word document you just created, file -> Save As -> Select HTML format, save an HTML document
Using Notepad to open the HTML file, search "
The code is used for 123).
Then we open the originally protected Word Document with UltraEdit or other similar tools, search for 7acfce5b, use it,
8 0 instead, save. At this time, the password of the Word document is cleared, you can cancel your document to protect your document, the password is not entered
, Press a carriage return.
MS has not provided patch on this vulnerability, I think the short-term may not solve this problem shortly. It is recommended to use this east.
The west is protected. =============== &
