If it was $20 instead, I would probably pay it anyway, but there's really no point.
Yes, that's why they don't really target individuals. But if they've found a couple of sloppy companies, jackpot!
There have to be more than 3 addresses. And it's Saturday, many companies cannot access their money until the banks open Monday. Only then we'll see how big the damage is...
You are right they are not targeting ordinary citizens but rather companies especially large ones even those who have a good firewall to protect their datas. This kind of attacks have been already a threat to the world and many big companies are starting to worry about those kind of attacks. Hope the government around the world will use the interpol to put those kinds of issues in a priority.
