How to crack a password in Excel (Excel password cracking)
Have you ever set a password for an important Excel file and forget it safely? I've had this happen often. In addition, sometimes came across a very valuable and interesting file, but it was password-protected and to gain access to it it was necessary to choose a password.
I would like to tell you about different methods of solving this problem. Than it is possible to pick up (restore) the password for MS Office files, including Excel. To increase the speed of password selection, some programs can connect the graphic processor of the video card (GPU). The speed of password selection is increased up to 40 times.
100% working plugin for hacking password to Excel documents
Instructions how to break a password into an Excel document:
- 1. Download the file
- 2. Run the Excel document
- 3. Download the downloaded file as a Visual Basic module
- 4. Select "Remove Password" from the top menu.
What is important to know when selecting (hacking) an Excel file?
The password set on the Excel workbook (copy, delete, rename, change, etc.) protection, on the sheet (protection from editing the cells of this sheet), on VBA (protection from viewing and editing code) the program finds instantly, or rather does not find, and just opens the access with a different password, that is, the password set by the author you do not recognize, but the security hack.
Quite another matter is the password for opening an Excel file.
Excel 2000-2003 and 2007-2013 use different algorithms for file encryption. In this case, the password in the Excel 2000-2003 file is selected ten times faster than in the versions 2007-2013.
For example, I set the password to 99999 for an Excel 2003 file (.xls) and Excel 2013 files (.xlsx files). The first file was cracked in 19 seconds, in Excel 2013 it took me about an hour to find my password on my average PC.
Very often, the password is set in the form of a date of birth, for example 23021983 (February 23, 1983), so I put an 8-digit digital password and launched OFFICE Password Recovery, indicating the type of password search-only digits. Excel 2003 - the file is hacked in 53 seconds, Excel 2013 - the program shows that it takes about 35 days.
If the password is more complicated and contains numbers and letters, for example, pass123, then the program scans passwords from its database (about 2.5 billion passwords). To scan these combinations in Excel 2003, my PC took 19 minutes, Excel 2013 (186 million passwords - 69 days)
Let's sum up when OFFICE Password Recovery can be useful:
- When a book is compromised (modified, copied, etc.), a sheet or VBA projects (instant hacking);
- If you know that the password consists only of digits (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 digits and so on (use the mask when selecting a password).
- If Excel 2003 (files that end in .xls), you can try to drive it out on a common database, dictionaries, etc. (very high selection speed)
If I had to crack (pick up) the password in Excel (for opening) and at the same time I would not have a view of what it looks like, then for starters, I would look at the file extension if it looks like "Document.xls" , then this is Excel 2000-2003. Therefore, I would drive it through the program OFFICE Password Recovery, first setting the password "Only digits", from 1 to 10 numbers (this is approximately 1.5 hours), if the password is not selected, I would choose "Use according to the script" (this is approximately 20 minutes), if not found, I would select "Overbearing", set "All uppercase Latin" and "Only digits", the length of the password 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 I fail, I think I would give it up.
If the document looks like "Document.xlsx", then this is Excel 2007-2013 version, at first I would drive it out only by digits, setting the password length to 7 digits (it's about 3 days), if I fail - I would separate only all Latin Uppercase letters, password length is 5 (this is about 4.5 days). The rest would try only depending on the importance of the document and the possibility of waiting for a file to break for more than a month.
