Irongeek.com is hosting an online class on password exploitation. The event was a fundraiser called ShoeCon, but they are hosting the entire series for everyone to share. Not only are the videos there, but you can download the powerpoint slides as well. There is a massive amount of information here on various topics like Hashcat, OCLHashcat, Cain, SAMDump2, Nir’s Password Recovery Tools, Password Renew, Backtrack 4 R1, UBCD4Win. There’s so much info, they split it into 3 sections. The videos are fairly long, between 1 and 2.5 hours each. What might surprise people is the amount of time that google is actually one of the main tools.
These videos can be a fantastic resource for hobby hackers, IT admins, and security professionals.
