Office Multi-document Password Cracker quickly recovers lost or forgotten passwords in all Microsoft Office documents and displays it on the screen literally in a minute. The application supports documents created in Word, Excel, PowerPoint, Outlook and Access, and the recovery process is almost instant thanks to advanced cracking technology implemented on the special password server. The interface of the program is genuinely simple. Upon startup Office Multi-document Password Cracker performs automatic search for password protected document in the Recent Documents folder.
If you need to open a specific document or if you want to search for secured documents in some particular location, there are corresponding toolbar buttons. Once the search finishes, the window clearly displays the number of documents of each given type among Microsoft Office documents the program was able to find.
Clicking on a document category in the list opens the list of specific type of documents. Office Multi-document Password Cracker recognizes and cracks the following types of passwords: a password to open, a password to modify, a document protection password, a password to VBA projects, worksheet and workbook passwords for MS Excel , database and user workgroup passwords for MS Access. All passwords in a document will be recovered or removed after you click the Crack button on the toolbar.
Though, you can crack any password individually by clicking the Crack link next to it. Any recovered password can be copied to the clipboard right away. Extracting the hash from a password-protected Microsoft Office file takes only a few seconds with the office2john tool. While the encryption standard across different Office products fluctuated throughout the years, none of them can stand up to office2john's hash-stealing abilities.
This tool is written in Python and can be run right from the terminal. To get started, we'll need to download the tool from GitHub since office2john is not included in the standard version of John the Ripper which should already be installed in your Kali system. This can easily be accomplished with wget.
In order to run office2john with Python , we will need to change into the same directory that it was installed into. For most of you, this will be Home by default just enter cd , but feel free to create a separate directory. Next, we need an appropriate file to test this on. I am using a simple DOCX file named "dummy. Download it to follow along. The password is "password" as you'll find out. You can also download documents made with Word and Word that shows up as to use for more examples.
Passwords for those are also "password The first thing we need to do is extract the hash of our password-protected Office file. Run the following command and pipe the output into "hash. To verify that the hash was extracted successfully, use the cat command. We can see that the hash I saved corresponds to Microsoft Office Hashcat wants only the file hash and nothing more. The newly edited line should look like this.
If we wanted to apply a rule to that, we could reference a path to our rules file with the -r switch. From here on out, the rules that we learned in our previous Hashcat article still apply.
You can use wordlists, apply rules, and more. Remember, attacking hashes takes both skill and luck. The first command above will run our hash against the rockyou. Here are a list of the Office types that Hashcat currently supports and their associated -m flags values.
