How to crack password in Excel (Excel password crack)

Как взломать пароль в Excel (Взлом пароля Excel)


Have you ever set a password to an important Excel file and forgot it safely? This has happened to me often. In addition, sometimes a very valuable and interesting file came across, but it was password protected and in order to gain access to it it was necessary to pick up a password.

I would like to tell you about various methods for solving this problem. How can I pick up (recover) a password for MS Office files, including Excel. To increase the speed of password guessing, some programs can connect a graphics processor to a video card (GPU). Password guessing speed increases up to 40 times.

What is important to know when selecting (hacking) an Excel file?

The password set on the Excel workbook (protection against copying, deleting, renaming, changing, and the like), on the sheet (protection against editing the cells of this sheet), on VBA (protection against viewing and editing code), the program finds it instantly, or rather it doesn’t, but it simply opens access with a different password, that is, you will not recognize the password set by the author, but you will crack the protection.

A completely different thing is the password to open the Excel file.

Excel 2000-2003 and 2007-2013 use different file encryption algorithms. At the same time, the password in the Excel 2000-2003 file is selected ten times faster than in versions 2007-2013.

For example, I set the password 99999 to an Excel 2003 file (files with the extension .xls) and Excel 2013 (files with the extension .xlsx). The program cracked the first file in 19 seconds, in Excel 2013 it took about an hour to select a password on my average PC power.

Very often, the password is set in the form of a date of birth, for example 23021983 (February 23, 1983), so I set an 8-digit digital password and launched OFFICE Password Recovery, indicating the type of password search - only numbers. Excel 2003 - file cracked in 53 seconds, Excel 2013 - the program shows that it will take about 35 days.

If the password is more complex and contains numbers and letters, for example pass123, then the program enumerates passwords from its database (about 2.5 billion passwords). It took 19 minutes for my PC to enumerate these combinations in Excel 2003, Excel 2013 (186 million passwords - 69 days)

Let's summarize when OFFICE Password Recovery can come in handy:

  • When breaking protection of a book (modification, copying, etc.), a sheet or VBA projects (instant hacking);
  • If you know that the password consists of numbers only (guaranteed and acceptable time)
  • If you know the structure of the password, for example, remember that the password starts with the word Vasya, and then some other numbers and the like (use the mask when selecting the password).
  • If Excel 2003 (files ending with .xls), you can try to run through a common database, dictionaries, etc. (very high selection speed)

If I needed to crack (pick up) a password in Excel (for opening) and at the same time I wouldn’t have any idea how it looks, then for a start, I would look at the file extension if it looks like “Document.xls” , then this is Excel 2000-2003. Therefore, I would run it through the OFFICE Password Recovery program, first setting the password “Only digits”, from 1 to 10 numbers (this is about 1.5 hours), if the password is not selected, I would select “Use according to the script” (this is about 20 minutes), if not found, then I would select "Bust", set "All uppercase Latin" and "Only numbers", the password length would be 7 (about 11 hours) or 8 (about 16 days) depending on the importance of the document and willingness to wait so much. If it fails, I think I would give up this business.

If the document looks like “Document.xlsx”, then this is the version of Excel 2007-2013, at first I would run it only by numbers, set the password length to 7 digits (this is about 3 days), if it fails, I would run it separately only for all Latin uppercase, password length 5 (this is about 4.5 days). I would try the rest only depending on the importance of the document and the ability to wait for a file to be cracked for more than a month.
