 Ransomware is based on extortion. So there are basically three models out there that are trying to do that old extortion racket, where you got to pay me or something bad will happen. The first thing they want to do is DDoS extortion. Pay me or I'm going to take your site offline. Nothing to do with this report. The second extortion is, I'm going to encrypt all your data so you don't have access to it. So operationally, you're shut down. This is a hard one because I talk about the flash to bang, and if you've never heard of that, if you see a lightning strike every five seconds you count before you hear the thunder, that's one mile away. So that flash to bang, if you lose credit cards, it could be six months. If you get hit by all your data is locked up and you're operationally shut down, you are immediately in crisis mode and it's public. And then the last thing is they're holding your data hostage. They're stealing the data and saying, we'll sell it back to you. And so as we think about this, these are traditionally, we think about somebody coming in spreading throughout the network, ex-filling data, and it's all been through hacking the people, coming in through social engineering software. And this year we saw a shift to zero days. They are actually, the hackers are developing zero days. They're paying bug bounties to other hackers to bring in zero days. And we're going back to more technical attacks. You think about things like go anywhere and move it. These are not trying to break in and these are great attacks from the hacker's point of view because they scale. I break into one point and I get access to multiple customers. And it's also changing the economy is getting much more complex. I may be a hacker that just gets initial access. Somebody else may be a hacker that does the actual ransomware. Somebody else may do the data ex-fill. It is ransomware as a service almost.
