I continued the work I previously explained by attempting to crack a Windows administrator password. This time I created a new windows administrator, booted up using a Kali Linux USB and launched Ophcrack to go after the administrator account I set up.
After lauching Ophcrack, I navigated to the Windows partition and then \WINDOWS\System32\Config to access the SAM database. I then downloaded a Rainbow Table called Vista Free and after about 10 minutes, the admittedly weak password I setup hello123 was cracked. I was not able to crack all of the accounts – presumably because they were adequately complex
.
I think next time I will experiment with chntpw to reset the Administrator password instead of attempting to crack it.
