Everything you need to know about the WannaCry / Wcry / WannaCrypt ransomware

What I still haven't had answered is how does the infection actually spread? The bottom of this article says not to open email attachments, but also mentions closing certain ports. Is this being activated accidentally by the users or is it spreading by some exploit?

Is it possible to just refuse the bitcoins that have this wallet in the ledger? That way they cannot spend the BTC they ransomed?

The article points out that the phone-home domains this ransomware uses were generated by keyboard-mashing. Can we tell what keyboard layout was used?

It's still unclear to me why this spread so much wider & faster than other exploits.

The title of this post is just annoying. &quot;Everything you need to know...&quot;.<p>Really? Everything? Will anything wrong happen if I will be a bit more curious than The Author?
