This ought to make me look like a hero at my new gig.  Again.

On a whim, I searched for a CryptoLocker decrypter this afternoon, because the old place I worked at and the new place I currently work at were both hit by a CryptoLocker virus.  Now, at the old place, we mostly had everything backed up.  At the new place, not quite so much.  I mean, everything is backed up now, but it wasn’t before I got here and they got hit with the virus.
In any case, I had a couple of files I wanted to get into that were hit with the virus.  So, naturally, I went to search for something to help.  Because, you know, it’s been a while and maybe someone had come up with a solution, right?
Well, as it turns out, they have.  FireEye, who I’m familiar with and Fox IT have setup a free service at Decryptolocker that will let you download a decryption program and upload an encrypted file, which they will use to generate a decrypt key that they send you via email.  When you get that, you follow their super simple instructions to decrypt your file.  It’s a command-line utility, but, hey, it works.

And, yes, I’ve tried it.  It took all of ten minutes to get the email with the key and then I was able to decrypt any of the effected files that I tried it on.
This restores my faith in humanity just a little!
