The massive ransomware attack known as WannaCry, which spread across tens of thousands of computers worldwide on May 12, demonstrates yet again the value of an airtight cybersecurity policy. WannaCry, which crippled high profile targets like Britain’s National Health Service (NHS) and Spanish telecom Telefonica, includes a National Security Agency (NSA) exploit called EternalBlue, which the intelligence agency lost control of last year.
But it’s not just large companies or systems like the NHS that are vulnerable to WannaCry. Andrew Stuart, managing director EMEA at Datto, said small businesses need to protect themselves from these attacks too, lest they suffer a fatal blow from cyber criminals who have managed to get their hands on a spy agency’s cyberweapon.
“Smaller businesses are just as likely to be hit by this worm, as well as the new variants that the NCSC is warning us to expect this week,” Stuart said. “The struggle for smaller firms is they don’t necessarily have the resources to call in experts to clean up their networks in the aftermath of an attack such as this.”
That doesn’t mean small businesses are defenseless, though, Stuart said. By taking the following steps, entrepreneurs can ensure their company – and by extension their livelihood – is protected from cyberattacks like WannaCry.

- Install the latest Windows update: A mid-March Windows update includes a patch that closes the vulnerability that makes WannaCry effective. Users who install this update will be insulated from the attack.
- Update anti-virus software: There remain many different types of viruses out there, and cybercriminals are always building on them and innovating. No doubt a variant of WannaCry will show up on the scene too. So, for added protection, make sure your anti-virus software is up to date.
- Back up all data: Finally, you can’t be locked out of your data for good if you have it backed up on hard drives that aren’t connected to your network. That way, if your network is infected, you still have access to your data. Once you clean up your network, it’s as simple as recovering your data from the backed-up source.
