|Password Recovery Solutions|
One of the basic security principles declared by Microsoft in concern to Office 2007 is to "make application functionality secure by default". Hence, Office 2007 implements a radically new format of files and the model of protection from unauthorized access to important data.
It has been less than 15 years since the first edition of Office was released, and the protection of documents is finally done competently. While in the older versions the encryption of document access password was weak and currently used versions of Office use the encryption of document access password by default that is compatible with the earlier versions (read more about it in the articles "Password Types in MS Word", "Password Types in Excel"), in Office 2007 everything has changed cardinally. Excel, Word, PowerPoint, and OneNote documents no longer offer the choice of encryption type when setting a document access password. While in the Office XP versions the default document access password encryption algorithm was RC4 40 bit, if you set a document access password in Office2007 - it will be encrypted with the algorithm AES 128. Also, if you open a document created in the older versions of office (2002, 2003) in Office 2007 with the default encryption mode, the old encryption algorithm will be replaced with the strong 128-bit encryption.
And while you could recover forgotten passwords for Office 2002, 2003 documents using our Guaranteed Recovery or Express Recovery technologies, in Office 2007 these cheap and quick document access recovery methods will not work, sorry.
In Office 2007 / 2010, you have a document that is reliably secured; however, if you have forgotten the password to it, and you need to access that document urgently - alas you will no longer be able to recover it within a minute using our Express Recovery Service. It is possible to use the regular brute forse, but since the password encryption algorithm uses the technology that significantly slows down and complicates the brute force attack, that will require a great amount of time - from several months to many years. It is also worthy to keep in mind the Microsoft's declaration that "Microsoft support professionals cannot assist, under any circumstances, in the breaking of passwords applied to files and features within Microsoft programs".
We would like to note, however, there is only one type of password that is complicated for the recovery; that is passwords for opening Word / Excel 2007 / 2010 documents. Other types of passwords (password to modify, workbook password, worksheet password, document protection password, read about them in the articles Password Types in Excel and Password Types in Word) can be hacked easily.
Passwords to open are extremely hard to break in Office 2007 / 2010. To recover
the password, brute-force attack or dictionary search must be used. These
programs have been developed in such a way that even the most optimized
password breaker works very slowly. There is no easy solution and no success
guarantee. Unless the password is very short or a constitutes a simple
dictionary word, you have to spend a lot of computing resources to recover
You can also rent our high-performance data center to break your password (Cloud Password Recovery Service). We will check at least 5,500,000,000 most common passwords using the most effective combination of Brute-force attack, Dictionary Attack and Smart-Force Attack. We continuously improve our computing capacity and increase the search depth accordingly to increase the probability of success. To complete such amount of work on your own, you would need about a year of non-stop operation of a modern dual-core computer. At our data center, the same job would take just 100 hours. Lear more...
