This is a good video. It is so important for users to double check the file extension on any file. The icon associated does not necessarily have to be indicative of what the extension truly is. For more on files, visit the IFCI lecture on Module 6 – Windows System Forensic Artifacts & Signature Analysis lecture.

Decent headway has been made in the battle against cryptolocker; http://www.bbc.com/news/technology-28661463, but new versions of this ransomware are popping up everywhere these days. Some safe computing techniques to help mitigate infection:
1) Do not open e-mails from unknown sources.
2) Never, ever open an attachment unless you were expecting it.
3) Backup your computer regularly.
4) Keep at least one backup off-line. These programs can find attached external drives and will try to encrypt them. This includes files backed using File History.

I agree with everything jczarny mentioned above. This video also shows how important up-to-date Antivirus and security suites are to protecting your workstation and assets.

This is a good straight forward demo of Cryptolocker, this virus is pretty nasty some variants also encrypt network shares. A few users in our organization have been hit and the as the video states the files are unrecoverable. There are a few variants however as jzcarny states that have figured out ways to recover files and group policy settings can prevent infection. Bitcoins can be difficult to get and can greatly fluxuate in value.

I recently reformatted my C drive and I noticed that when i was reinstalling some of the applications I previously had, the installation downloaded malvertising programs, too. This happened twice. Maybe the next time it could be a ransomware. This is a good video to watch and really know what will happen. I would hate to have all my files by un-decryptable.
