How do you even know those addresses? Also, aren't like 200,000 computers infected already? in my evil mind, if I was a smart hacker, I would use a different address per computer.
I would do the same. But for some reasons the hackers seem to use only a handful of Bitcoin addresses.
Maybe they don't even care who pays and who doesn't (did you hear of successful data recover after this ransomware, after paying the price?). Or maybe they don't know enough about Bitcoin?
My take is that they don't care if the hacked bitcoins get easily detected by curious people (basically the entire bitcoin community is monitoring how this evolves so im sure they knew they would get traced carefully by community members).
Even if they used thousands of addresses, that would be just more of an headache when trying to mix them.
All these criminals have to do once they got all the money they wanted, is to send it all at some mixing site over tor and that's it, you lose track of it all, and that's where unfortunately all the people that got infected will never see their money back.
But let this be an useful lesson for people to take more seriously their jobs.
