Il primo e più semplice modo per ressettare la password di Windows (dal 2000 al 2003 passando per Xp o Vista) è utilizzare il livecd di Ophcrack:
What is ophcrack?
Ophcrack is a free Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. It comes with a Graphical User Interface and runs on multiple platforms.
Features:
- » Runs on Windows, Linux/Unix, Mac OS X, ...
- » Cracks LM and NTLM hashes.
- » Free tables available for Windows XP and Vista.
- » Brute-force module for simple passwords.
- » Audit mode and CSV export.
- » Real-time graphs to analyze the passwords.
- » LiveCD available to simplify the cracking.
- » Loads hashes from encrypted SAM recovered from a Windows partition, Vista included.
- » Free and open source software (GPL).
poi dai dettagli:
Support new Vista free tables: We computed new Vista tables based on a dictionary. Some variations are applied to the words of the dictionary before being added to the tables. It enables us to release a brand new Vista LiveCD.
Questo tool lo uso dalla versione 1.1.1 e funziona perfettamente e rapidamente, anche meno di un minuto con tutte le password da dizionario (nomi con numeri o parole varie), non trova le password con i caratteri speciali come le chioccioline, cancelletti ecc..., in tal caso non ci si può basare sulla ricerca veloce da dizionario ma su quella a brute-force (molto lunga).
Nel caso che il semplicissimo ophcrack no trovi la password utilizzando il dizionario, invece di usare il brute-force, consiglio questo altro tool: EBCD
Dalla pagina del sito EBCD:
