EXPERT OPINION Cybercriminals are increasingly using compromised credentials to access email accounts, sensitive information and corporate systems. Proofpoint research found that account compromise was in fact the leading method of cyberattack in the UAE in 2019, impacting 28% of companies, followed by credential phishing (20%) and insider threats (17%). Phishing and impersonation attacks/Business Email Compromise (BEC) attacks accounted for 15% each among the organisations targeted last year. In line with this, email fraud via Business Email Compromise (BEC), in which an attacker gains access to an email account and spoofs its owner, is on the rise globally – and is now being described as one of the most expensive threats on the cyber landscape. In fact, the latest FBI report estimates total worldwide losses as a result of BEC at US$1.7 billion in 2019. Evidently, the threat outlook is fast evolving and we will continue to witness cybercriminals trying to gain foothold and steal sensitive information via emailborne attacks. How important is human behaviour in preventing these types of attacks? Cybercriminals are increasingly targeting people rather than infrastructure. In fact, 99% of cyberattacks require human interaction to be successful. CISOs and CSOs in the UAE recognise this human risk to their organisations, with 39% believing that their employees make their business vulnerable to a cyberattack. Common security errors made by employees, according to CSOs and CISOs, include poor password hygiene (29%), mishandling sensitive information (25%), falling for phishing attacks (24%) and clicking on malicious links (20%). Employee education and security awareness is often the difference between an attempted cyberattack and a successful one. Interestingly, 19% cited criminal insider threats as a growing concern for businesses. Despite facing a fast-evolving threat landscape, 75% of CISOs and CSOs in the UAE admitted to training their employees on cybersecurity best practices as little as twice a year or less. Meanwhile, only 23% of organisations in the UAE train their employees more than three times a year. Organisations must ensure that their employees are equipped with the knowledge and the tools to defend against all manner of threats. Employees at all levels must understand how simple behaviours – password reuse and mishandling of data – can have significant, far-reaching consequences. In order to do that, companies need to ensure they deploy regular and effective security awareness training to educate employees about best practices as well as establish a people-centric strategy to defend against threat actors’ unwavering focus on compromising end-users. What should a robust email security strategy look like? The best email security strategies foster a combination of technology and people. With the constant uptick in phishing attacks, it’s vital that businesses invest 42 Issue 29 | www.intelligentciso.com
