Re: Back up your data!
There is a more simpler solution to protecting your data other than just backups.

Encrypt your data. CryptoWall can't encrypt files that are already encrypted by the end user.

The data can be decrypted on access which would lock the files currently opened. When the file is closed it is

automatically re-encrypted in realtime. As an extra layer of security it is also possible to encrypt volume shadow

copies of the files as the behavior of CryptoWall will automatically sdelete (Secure Delete) all shadow copy data

on the infected machine. I am no way suggesting not to backup your data. However, a proper retention policy

should also be correctly set to seven or more days. If a backup whether it be to a local, network drive, or cloud

based is not encrypted there remains the risk of the files being encrypted by the ransomware and changes of

modified files by CryptoWall propagating and overwriting the original backup of end user data. Also, CrytoWall

only affects files by extention (ie .docx, .qbw, .xlsx) If a file extention is modified to something completely

obscure in no relation with any application they will remain unaffected by this ransomware.

accuracy of amount in question?
According to Howard, the researchers were able to track $325 million in ransom payments through the Bitcoin system. "Our estimate is conservatively low. We think it could easily be double that number but did not have the direct evidence to claim it."

 

So really you could say that is was only half as much with just as much confidence?

I often wonder where the numbers for this come from,  a guess may not be very newsworthy.

What evidence is there to prove it one way or another?

How prevalent is Ransomware at the enterprise level with network drives? Are they affected in the same way a regular endpoint will be?

Back up your data!
Please people, perform due diligence and don't let ransomware cripple us. Back up your data to a another source regularly. Make sure your OS has default backup settings enabled such as Windows "Previous Versions". This could save tons of money and headaches.
