Over the weekend, some White Hats figured out how to turn it off ("kill switch"). The whole thing looks to be a big old wet firecracker.
But hang on:
Miscreants have launched a ransomware worm variant that abuses the same vulnerability as the infamous WannaCrypt malware.
Some day soon there will be a version that won't be easily shut off. That will be the End Of The World (as we know it).Danish firm Heimdal Security warned on Sunday that the new Uiwix strain doesn't include a kill-switch domain, like the one that proved instrumental in minimising the harm caused by WannaCrypt last week, although this is subject to some dispute.
Except maybe not. So what if your files are all placed off limits by malware encryption, as long as you have another copy.
I have been posting about this for a long time, and co-blogger ASM826 (who does IT for a living) has been talking about this, too. Here is a starting point for some information about why this is important. Get a backup service (one of the ones where your data gets uploaded to their cloud) and then you will be basically immune to ransomware - if you get infected just reinstall the OS and restore your data from the cloud backup.
So the ransomware is getting nastier, and it's the end of the world as we know it. But if you back up your data, you'll feel fine.
