Password recovery methods developed by LastBit Corp.
Smart Force Attack
Smart Force Attack is the perfected variant of Brute force attack, developed by LastBit Corp. This password recovery method is based on the supposition that a password consists of exceptionally letters and has sense. Smart Force Attack is based on the statistical tables built by means of analyzing of a large amount of texts. This is a very time effective way to crack or recover a password as it doesn’t check meaningless combinations of letters. The effectiveness of this method can be compared to that of Dictionary attack with a very large dictionary. If the password was generated automatically (randomly), Smart Force Attack method can’t be used. It also won’t recover passwords with digits and non-alpha characters. It’s possible to check up to 11 characters in length in a reasonable amount of time with Smart Force Attack method.
Guaranteed Recovery
Guaranteed Recovery method allows to recover password of any length in an acceptable amount of time. This method, introduced by LastBit Corp in 1999, was the first solution for guaranteed recovery of password protected Word and Excel documents. The peculiarity of this method is that the original password remains unknown but the document is decrypted and protection is removed.
Express Recovery
Express Recovery is an improved Guaranteed Recovery method. The main difference is that the user needs only several minutes to recover the password. Also about 3% of Exel documents can't be password recovered, in this case Express recovery method is used.
