Hooray for good backups, but this poo poo seriously SUCKS. I can see in a year most businesses will simply not be on the internet if they want to function. If viruses were going to drive businesses to air-gap it already would have happened. There's pretty substantial benefits to being online, so in the end businesses will suck it up and pay for a decent backup solution. If you have backups, it's only slightly more annoying than any other virus. And really airgapping isn't a total solution either, it just makes it a little more difficult to spread. Before internet connectivity, floppy disks were a major vector. USB sticks are pretty loving insecure, if airgaps became common then viruses would spread by that. And you bet your rear end an airgapped business is going to be plugging in USB sticks like there's no tomorrow. Hypothetical "airgap variant" - spreads via USB stick, with a (say) 2-week trigger latency or a fixed trigger time to help it spread. Rather than sending the decryption key back to a C&C server and deleting it from the victim's PC, it encrypts the decryption key (with the hacker's public key) and leaves an encrypted copy on the victim's machine. You have to send the encrypted decryption key back to the hacker along with your ransom, and he uses his private key to decrypt it for you.

The latest variants are not just encrypting Office files. They're getting nearly everything. If you are getting hit with a couple grand worth of infections "every other weak" and you aren't investing a paltry sum into a backup system, you deserve to be run out of business for Not Being Able To Take A Hint. Losing internet access is going to impair you much more than the cost of a backup system. If you are losing $3,000 every two weeks - you can buy an awful lot of backup system for $78,000 a year.
