How i can crack Excel_2007 file ?

Do you have the computer the Excel file came from?

To follow on Jonathan's question, do you have an image of the machine with the Excel file in question, or just the Excel file stand alone?

If you have the image and access to FTK, get it indexed and produce a pword list from the indexed image. Pump that into PRTK with the file, I've yet to come across a pswd that isnt cracked thatg way…

If it's the stand alone file, you can try the office rainbow table(s) with PRTK. I've found brute-forcing to be far too time consuming without a machine-graphcs card farm dedicated to the work.

Cheers!

This piece of software will do it…

Ok at the moment i don't have an image of the machine (but i can try to request) So….i have FTK 2.7v with this i can index and produce a password list? how? now i try PRTK….

Thanks a lot for help wink

If you have an image of the HDD, one of the functions of FTK is Create a Word List. You then create a dictionary from that word list in PRTK. Brute forcing an Excel password is a very time consuming process.

ok ok just a moment i have FTK imager (freeware) you are probably talknig of the other verison….also PRTK is not freware yes? ok you think i can find somewhere an evaluation copy of this software? if i can bu sure to rescue this password i can talk with my boss and buy this….do you know about price?

Check out Access Data for more information about PRTK and the other decryption products by access data. Also everyone is referencing FTK the forensic platform for examinations. It's Forensic Tool Kit.

I personally use Access Data DNA with a 20-30 machine cluster including 3 PS3's. That is fast enough for all my 2007 needs 😉

The alternative would be to use online solutions but afaik they aren't free.

And I also have a question about those kind of services Can they be used on forensic investigations ? I mean, could the evidence still be used in a court ?

BTW, if you are willing to use one here's a list (some of them are pricey)
1. http//passwordnow.com/
2. http//www.decryptum.com/
3. http//lastbit.com/express-recovery.asp (97-2003)
4. http//lastbit.com/mso2k7srv.asp (2007/2010)

I don't think is a good idea to use the online service, in relations with the reserve of the evidence…..ok i have tried with PRTK but without results at this time i can only try to request the disk and try with the method of word list and after PRTK…..this software said me this is an XP/2003 excel file
