Once again news of a major ransomware attack, named WannaCry which targets Microsoft Windows, has made the headlines and while its spread has been brought under control, security analysts are in agreement that more powerful variants will soon appear and that the release of more prolific and damaging ransomware will also become more common.
Alarming, yes but this is what we can expect the future to be and if we want to protect our valuable data, there are just a few simple things we need to do, to minimise the risk of our systems and data being compromised.
1. Keep your operating systems (OS) up-to-date.
2. Keep all your applications that connect to the net such as your web browser and email clients up to date.
3. Keep your anti-virus defininitions up-to-date.
4. Keep your firewall up-to-date.
1. Be on the lookout for phishing emails, authentic looking emails which contain links or attachments to apparently genuine websites.
2. Run only known and trusted application macros.
3. Take the necessary precautions to ensure that removable media do not introduce malicious content.
1. Ensure you have a backup strategy in place.
2. Backup your data regularly.
3. Limit access to your backed-up data.
It may be inconvenient to take these precautionary steps but it is certainly less inconvenient and cheaper than dealing with the consequences of a ransomware demand. As users of the internet we have a collective responsibility to ensure that we are not contributors to the propagation of malware.
