EXPERT OPINION a new technique where they insert phishing emails into an active email thread to increase the likelihood of it being clicked on. This type of attack is known as spearfishing and if the target is a member of the C-suite, it is called ‘whale phishing’. But regardless of who is being targeted, everyone is susceptible to a carefully crafted email arriving when they are just distracted enough to not be paying attention. How ransomware will progress during 2020 What has been on the rise, and what I predict will get worse in 2020, are the more targeted ransomware attacks that cost businesses more from an operational and regulatory perspective. Malware and ransomware attacks, in general, are a completely different game now because these attacks are being targeted and specifically crafted to certain internal systems. Another factor contributing to the growing attacks on businesses and enterprise organisations is the ready availability of Ransomware-as-a-Service (RaaS) offerings, which is something I predicted years ago would happen as an evolution of ransomware. And in 2020 we are already seeing another shift, with ransomware jumping to leverage the timely cybercriminal opportunity around COVID-19, which demonstrates that ransomware evolution is not just about targeted attacks. And this sort of multi-pronged attack front is much harder to defend against. FortiGuard Labs has been actively monitoring the threat landscape during this time, and we have seen a significant increase in threats targeting individuals through phishing and infected websites. • Wherever possible, patch and update operating systems, devices and software. Make this a priority for remote workers – especially What can organisations do? We are at an especially vulnerable moment in our transition to a digital economy. Organisations need to take steps now to protect their networks and networked resources from the growing problem of sophisticated ransomware. While each network environment is different, here are a few things any organisation can begin to implement today to reduce their risk from ransomware and other advanced threats. those using personal devices to connect to the corporate network. For devices that can’t be patched, ensure that appropriate proximity controls and alerts are in place. It is also important to make sure that all endpoint devices have advanced security installed, such as anti-exploit and EDR solutions. • Businesses need to make sure that access controls, such as multifactor authentication and even network access control solutions are in place.
