It’s called “WannaCry”, here’s how to protect yourself
The first question on everyone’s mind this morning as they come back into work is “did we get hit”?
At this stage, most know roughly what’s happened over the weekend that has some big companies losing their minds. A swath of businesses, big and small, have been hit by Ransomware, the big-ticket item in cyber crime at the moment.
It’s been dubbed “Wannacry”, and if you’ve experienced Ransomware in your business, you know why. If you’re a small business without a tech division I’m sure you’re worried, and wondering what to look for and what to do. There are plenty of resources popping up online giving advice on what you can do, but you’re here now so here are a few suggestions you should follow.
Steps to protect yourself
- If you use Windows, install the patch that Microsoft has released to block the specific exploit that the WannaCry ransomware is using. Click here for instructions. For unsupported versions like Windows XP, 2008, Server 2003 you can click here to get the patch from the update catalog.
- Update your computers’ antivirus signatures and run a scan. Most have added signatures to deal with the latest vulnerability. If you don’t have anti-virus on your PC you can download and run Windows Defender for free or for older versions you can download Windows Security Essentials.
- DO NOT click on any links within any email until you are 100% certain the the email is genuine. Make a call to the sender and make sure it’s legit. It will only cost you 30 seconds and can save you weeks. Be wary of all email for the foreseeable, especially from unknown sources.
- Keep your web browsing on business computers, strictly for business only and restricted it to known sites. It mightn’t be popular but you should enforce this.
- Keep regular backups, daily if possible. If ransomware hits, backups are your answer. Restore your files to the last time you’re certain you weren’t infected, then install the updates and run your anti-virus scan.
Spread the word
Not everyone would have heard over the weekend that they’re at risk. Share this post to spread the word and if you know anyone in business, send them and email or give them a call and let them know that they need to make sure that they aren’t at risk.
