Breaking Windows passwords with OphCrack

What do you do when all record and memory of a password is done for a Windows install, but the information on the PC is important?
If you’re a non-technical person you call one of us nerd types and we spend hours fudging a solution. In years past this job was painful, and often fruitless. Best quick effort I used to make was to rip out the hard disk, and attach to another system s I could scrape the file off onto a portable drive.
No longer. Now the solution is to use the OphCrack tools, which basically make cracking a windows password a total cake walk.
Cost: Free. Open source from Sourceforge.
The steps were:
- Download the OphCrack Live CD .iso (approx 450mb)
- Burn the .iso to CD
- Boot form that CD
- Write down the passwords after it extracted them
- Reboot and login like we knew the passwords all along
Frigg’n amazing. No corruption, no mess.
I also had to grab a free Iso burning app, and chose CDBurnerXP which did the job perfectly too. All it took as a little time digging for the right tool, and then following the instructions. It took me more time to find a blank CD and case in the office than to hack the passwords. Thats crazy good.
Happy hacking, and forget your passwords at will folks.
