Protect your business against fraudulent emails

Business Email Protection Guide

According to Kaspersky Lab “Spam and phishing in 2016” report, about 20% of all spam emails in Q4 2016 distributed ransomware Trojans.

‘A How To Guide to Protecting your Business’

Email scamming and scammers have been around for a long time and many see them as a bit of a joke as they’ve always been very easy to spot. Unfortunately, this is no longer the case as these latest emails appear to be extremely genuine, can often call you by name, and can appear to come from reputable Irish companies, or someone you know – even within your organisation.


The content of these emails generally requires that you click a link within the email body, or open an attachment in the email. The results of opening the attachment or link can be very malicious, and can cause significant damage.


While technology can block the majority of these emails, it cannot block them all. We would advise that you circulate an email to all email users within your organisation to be very cautious when opening email attachments, and to not click any links within these emails, even if it is from someone you know.


If you are unsure in any way, please telephone and speak with the person you received the mail from to verify the content.


Of particular note, are emails claiming to be from:


  • Revenue Commissioners (often with Gaeilge)
  • Eircom / eir
  • Senior people within the company, asking to pay bills
  • National Lottery
  • Bank of Ireland

3 – 3 copies of the Data

2 – Held on 2 different forms of Media

1 – 1 copy held offsite.

How to Protect Your Business From WannaCry


WannaCry (also known as WannaCrypt0r) is a new ransomware attack which started affecting computers last week. It gains access through a backdoor built into older versions of Windows and then encrypts the host hard drive. To unencrypt the files, the victim must send money to the hackers. So far WannaCry has affected thousands of computers and servers, across hundreds of organisations, including the NHS, Telefónica, Nissan and some Irish hospitals, causing untold havoc among those affected.

How to Protect Yourself

WannaCry is unlike other ransomware attacks as it does not spread through infected email links or files, but instead installs automatically, without user input. This means that users must be proactive in protecting themselves from the attack. Users should make sure that their computers are fully updated, and any users running Windows 8 or below should download and install the patch released by Microsoft here.

To protect yourself from future malware attacks you should never open links or files from people you don’t know or trust. Malware is often spread through infected Word or PDF documents, so do not assume any file is safe if it is from an unknown source.

For a comprehensive anti-malware solution, users should consider Webroot Security and Sleepless Cloud Backup to stop threats from gaining access to your systems and to keep your files safe, away from the risk of infection.
