General instruction on recovering passwords from hashes

 

Use this simple instruction for the recovery of any passwords in Passcape Software programs. This instruction is offered in the format of recommendation and is meant primarily for the recovery of passwords encrypted with OWF; e.g., from hashes.

 

When recovering certain types of passwords - for instance, Windows user passwords - the major question is: How to organize the recovery process - which attack should I start with to raise the probability of its successful completion?
 

For choosing the type and the sequence of the attacks, we advise to follow this algorithm, which is applicable in the majority of cases to all types of passwords to be recovered:

  • First, enable the preliminary attack option, if it is available. It will help to recover simple and frequently used combinations.
  • Second, if you are aware of any specifics of the password you are looking for, it's better to try mask attack or base-word attack first. Specifically, if you know a part of the password - using mask attack would be more effective. If you know the basic component of the password or, for example, know the password but don't remember the sequence of caps and lowercase characters in it, base-word attack would do the job better.

If you have no information on the password you are looking for, which occurs most frequently, be guided by the following sequence of steps:

1

2

Artificial Intelligence attack options
Launch AI attack with mutation and indexing options set to light.   If the password was not found, try once again with mutation option set to normal level and indexing set to deep.

4

Dictionary attack options
Run dictionary attack with the mutation option disabled.   Launch dictionary attack with the mutation option enabled; the depth of mutation depends on the amount of available time and the attack speed.
