My apologies.. It should be “ransomware”. Most hit are Europe,Russia and some Asian countries. America was saved partly because stop switch found by a blogger accidentally as given in the link which gave some extra time for patching the systems.
I read it gets in by getting someone to click on a .zip file attached to an email.
I also read that it was hitting older Windows OS, and that Microsoft has released patches for them (so everybody update!) ... Okay, here’s an article that seems to give a reasonable overview of the attack.
I heard something about this on the morning news. It’s mostly affecting people in Russia and China. But, of course, electronic malice can spread with astounding speed.
A few years ago, my computer became infected by CryptoLocker. What a nightmare!
It was actually spread through a few methods. First being your common one from people clicking stuff. But here is the really bad thing. It was using a exploit in SMB which basically means it could spread through a network with absolutely no user interaction. That is how it was taking down entire institutions.
And if you are concerned running Windows update will patch the vuln.
CNN and others have made the dude that stopped this as some lucky fool (they have started fixing this). He is actually a top notch security guy.
Thing two. This was stopped by the payload checking if a domain name existed. If it did not exist it would fuck your computer. If it did exist it would not fuck your computer. I don’t really get the logic of taking this approach.
