As you’ve no doubt heard by now, a new strain of ransomware called WannaCry is currently spreading across the internet.
Ransomware is a computer virus which encrypts the content of your hard drive, threatening to delete all of your files unless you pay a ransom.
In this video, CNN explains exactly what WannaCry is, and how it’s spreading around the globe. While the spread peaked on Friday, it’s still happening now.
Ransomware is a particularly nasty form of malware. However, it can be mitigated by keeping your system up to date, and by regularly backing up your files to an external hard drive.
