This is yet another of my success story. Recently one of my client throw me a Microsoft Powerpoint (.ppt) file and asked me to crack it. I love when my clients throw me challenges!
I know that it is of course possible because previously I had crack a Microsoft Excel. But too bad I did not blog about it and now I even forgot how I did that hack. That is the reason why I am blogging now regarding this Powerpoint hack, I know I will forget soon, so better note it in blog rather than diary as it would benefit others as well.
My game started like this, I googled, googled, and googled for whole day and found only 1 software with the name of "Office Password Recovery Magic" which I got it with serial number so it was full-ware. But sad that the software was using "Brute-force Attack" as default if you know what I mean, it is something like the software will try inserting all possible characters and it will take hell a lot of time. Guess what? I run the software over-night on my server machine. Even after 1 day also could not hack it.
As you might know, I hate waiting, so once again, back to googling. This time I found "Advanced Office Password Recovery Professional (AOPRP)." It is a recommended tool for hacking MS Office files. I tried looking for the cracked version of it but did not find any. I did download some different version and unable to crack the software as version conflict. Finally I found the bundle pack which was nearly 66MB. Bundle pack consist of all Elcomsoft's software with the serial numbers.
I downloaded the bundle, installed only "Advanced Office Password Recovery 4.11 Professional". I used the given serial and the software was cracked. I run the software and opened the Powerpoint file. Take note that I install the software on my laptop as well as server. I run the software from the server as I doubt it would take another 1 or 2 days to complete the hacking of the Powerpoint through Brute-force attack.
AOPRP's default attack mode is dictionary. I proceed the attack and within less than 1 second, it showed me the password! Seriously! It took just 1 second? Hell, how dumb I was for running the previous software over-night?
See the attached screenshot: (password showed in just 1 second? Gosh, hackers are smarter)
If you drop to this blog while you are looking for software to hack and I am glad to share with you my knowledge and the software, download this:

If in case your file password is not dictionary password, then try the brute-force attack and give it some time.
Bottom line, as moral of the story; always use 14 digit above password and remember to include numbers and symbols when you want to protect your file. Example password: reganrajan*87#smart. This password would at least take 2 to 3 days to be hacked on brute-force attack (depend on your CPU speed as well). Only the person who is sincere to hack your file would wait until 3 days, duh!
Have fun kids! Ops, have funs guys!

it doesn't work..
Like I said, there is many ways of attacking the password. If Dictionary attack doesn't work for your file, turn on the Brutal-Force attack. But it would take extremely longer time to crack the file. It might take few days to hack a complicated password. Password are not stored in the file itself. So if you were thinking its easy for crack-software to extract the password from the file, then you are wrong. Only the encrypted-password is stored and it cannot be reversed. So crack software like this would try to match the encrypted-password by trying all possibilities. Good luck again and be patient if you are sincere about cracking the file.
You know of anything in the market that can open at least a 24 character open the file password for both Excel and Powerpoint?
Not really. I haven't come across such complicated cracking.
