Either choose strong passwords, or don’t bother with a password at all

Earlier today I downloaded the latest Live CD for Ophcrack, the Windows password cracker, and tried it out on a Vista install to see how good of a password buster it is.

Conclusion: Either choose strong passwords, or don’t bother with a password at all.

Here’s the test – I took a virtual PC that uses Windows Vista that I’ve been sharing with a few friends (Fred, Barney, Betty and Wilma … you might know them) and put dosage for propecia this up against the Live CD to see how many passwords I could recover.

The process went something like this:

  • Download Ophcrack Live CD
  • Burn a CD (although I didn’t need to do this – I just booted the virtual machine off the .ISO file)
  • Let Ophcrack do its stuff

The results were quite staggering. In less than 50 seconds three weak passwords had been recovered (shame on you pcdoc, Fred and Betty … I’m not letting you on my systems again). However, two much longer and more complex passwords (one consisting of alphanumeric characters, the other more complex) survived.

You have been warned …
