Maybe most people have figured out that there is no use in paying because the program doesn't know who has paid.
Paying a bunch of criminals is no solution. If you pay them once, you will give them incentive to continue doing so. Plus you don't know if your files will really be decrypted after paying. Only solution is to either professionally have the systems 'cleaned', or they need to be wiped out and a back up being installed. I am quite happy that the number of paid ransom is severely lacking if you take the size of this attack into consideration.
You do not trust the criminal? There is a solution - In the future, malware will have smart contracts. You can be sure that your files will be decrypted once you pay the ransom. The only way to transact with an untrustworthy person.
Seriously, even if I know my files will get decrypted I will never pay. I want to avoid one thing -- giving them incentive to continue extorting others. And that happens exactly by not paying. If no one pays, eventually these attacks will dry out. I make backups of everything important every day (if things needs to be backed up), and store it at external drives. If my system gets locked, I will secure erase my hdd and do a fresh install -- no problem.
the problem is no files have been decrypted so far,they are not only dirty extorters but liars as well
and I agree-do not pay any of the scum who attempt to blackmail you,backup your documents,have your installation disks handy
and if shit hits the fan-spend a couple of hours reinstalling your system after a full format
