Ransomware is a type of malicious software that blocks access to your data or threatens to publish it until a ransom is paid.
*Details for home users
There are two types of ransomware – lockscreen ransomware and encryption ransomware.
Lockscreen ransomware shows a full-screen message that prevents you from accessing your PC or files. It says you have to pay money (a “ransom”) to get access to your PC again.
Encryption ransomware changes your files so you can’t open them. It does this by encrypting the files – see the Details for enterprises section if you’re interested in the technologies and techniques we’ve seen. . . . . . . . . .
*How big is the ransomware problem?
Ransomware is a global problem. The US, Italy, Russia, Korea, and Spain saw the most ransomware encounters in 2016. . . . . . . . . . We’re still seeing significant amounts of email that carry ransomware downloaders. A total of 500M of these emails are being sent out every quarter. . . . . . .
