Protect your Small Business from Wannacry Ransomware

I’m sure you’re aware of the ransomware attack that occurred recently, affecting organisations all over the country, including the NHS, and thousands of businesses across Europe!!

These kinds of attacks can be very worrying for any small business.

How does the wannacry ransomware virus spread?

The virus spreads normally hidden within Word documents, PDFs and other files normally sent via email, or through a secondary infection on computers already affected by viruses or malware that offer a back door for further attacks.

Emails are getting really sophisticated and it can be difficult to tell which are genuine and which aren’t.

What happens when you get infected?

The virus encrypts your files and folders so you can’t access them. Instead, you get a prompt which includes; a ransom demand, a countdown timer and bitcoin wallet to pay the ransom into.

To get access to your files and folders back, you need to pay the ransom fee of around $300 (cost varies making it harder to track). If you don’t pay before the timer expires, then you will lose your data!!!. Some people have reported that even if the ransom fee has been paid, they still don’t get their data back.

Could the NHS have done anything about this?

Microsoft did release a patch recently which would have helped, however it seems that the NHS didn’t implement this in a timely manner.

What can my small business do?

There are four main things you can do to help protect your business against ransomware.

1. Don’t open any emails or attachments which don’t look genuine. This can be difficult due to the sophistication of recent emails.

2. Install all software patches as soon as possible. Software vendors like Microsoft often release patches to protect your computer. Lots of people see these updates as annoying. Worrying, some businesses don’t install them at all. It’s essential that these updates are installed in a timely manner.

3. Use good anti-virus software. Free anti-virus software isn’t any use. You need a good, paid version of anti-virus software which can help protect your computer and business network.

4. Ensure your backup is robust, working and fully tested. If the worst thing happens and your business gets infected with ransomware, then you need to be able to restore your data from backups. It’s essential that a backup is remote from the computer that ransomware infected, ideally cloud-based. You also need to be ideally taking backups several times every day so if you do need to restore from backup, the data isn’t too out of date.
