A ransomware worm is rapidly taking over computers around the world. Here’s what you need to know to protect your computers and networks.
This particular worm, known by several names including WannaCry and WCry, is a type of computer virus called ransomware. Ransomware, as regular Tech Tips readers know, is especially nasty because it hijacks your computer and encrypts your data, then demands a ransom to decrypt it. A worm is a virus that worms its way through computer networks. Therefore, as you can imagine, a ransomware worm has the potential to wreak havoc worldwide. And that’s exactly what WannaCry and its variants are doing.
Your best protection is prevention. While this virus can be removed, the data it encrypts CANNOT be decrypted. Experts typically recommend not paying the ransom, as there is no guarantee you will recover your data even if you do. A current offline backup is the only way to preserve your information in the event of a ransomware attack.
Windows users, update NOW. If you’re on an old version of Windows and can’t update (anything except Win7, Win8.1, and Win10), this is your wake-up call to upgrade to a newer version. Yes, they released an XP patch. No, that doesn’t mean XP is safe. It means they had to patch XP because it’s used so widely in critical environments like hospitals. And that was an unprecedented move, as Microsoft had previously declared that XP would receive no further security updates. That indicates how serious the situation is. Microsoft has more information about supported versions of Windows on their Windows end-of-support page.
And, everyone – BACK UP YOUR DATA. Seriously. Back it up. Right now. Mac users, you too, you’re not immune to ransomware. Everybody BACK UP YOUR DATA ON A SEPARATE NON-NETWORKED DRIVE AND KEEP IT OFFLINE.
Spread the word. Tell everyone: business associates, friends, family, neighbors, random strangers. Send them a link to this article and remind them to back up and update their computers immediately.
If you’ve already been affected by the WannaCry worm, here’s some information that can help.
