UPDATE: Be sure to read the comments to this post. I am posting new information and updates as comments. There is a lot of information there.

 

Yes, again we see Cryptolocker. My client emailed me the following “I received an email on Friday from Energy Australia that took me to a website and it asked me to run a program but I could not open anything I believe that email may have caused this issue if that is of any help”

This falls in line with other peoples observations i.e. http://blogs.appriver.com/Blog/bid/102814/New-CryptoLocker-Has-a-Walkabout

 

We have not yet worked out how this version works nor what files have been affected. Here is the text
  !!! YOUR SYSTEM IS HACKED !!! All your files was encrypted with Cryptolocker!   This means that without the decryption key the recovery of your files is not possible, If your files have a value to you and you are willing to pay me for the decryption key please contact me: decrypt-request@mail.ua   You have 3 days to pay for my services. After this period, you will lose all your files.   Anti-virus software can remove Cryptolocker, but can not decrypt your fles. The only way to recover your files -is to pay for the decryption key.   Information for IT-specialist:   Data was encrypted with AES (Rijndael) algorithm with the session key length if 256 bits. Session key is encrypted with RSA (2048 bits) algorithm. Public-key is enclosed into Cryptolocker. Private-key for decryption of the session key is stored only in my database. To crack this key, you will need more than a million years time.
