FEATURE: THREAT ASSESSMENT ////////////////////////////////////////////////////////////////////////// Email continues to be one of the key attack vectors for cybercriminals, according to recent research. Fady Younes, Cybersecurity Director, Middle East and Africa, Cisco, tells us what the main risks are and how to mitigate these. W What are the most common problems and risks for businesses regarding email attacks? In May 2019, over 85% of all email was spam. Email continues to be the number one vector for malware distribution and phishing, with many cybercriminals intending to exploit sensitive information and commit fraud. Cisco’s 2019 CISO Benchmark Survey discovered that 56% of CISOs find defending against user behaviour ‘very challenging’, with security concerns being graded higher than other worries including public cloud and mobile device. A total of 70% of CISOs polled admitted that protecting against email threats is becoming increasingly difficult, while 75% experienced operational impacts as a result of criminal activity. Scams such as Office 365 phishing have enabled cybercriminals to steal sensitive data, using fake sites that mimic the online platform to trick users into giving away their details. A total of 27% of advanced email attacks are launched from compromised email accounts, up 7% from the last quarter of 2018. The CISO Benchmark Survey also found that two thirds of business email compromise (BEC) scams still use free webmail accounts, with 28% tailoring their attacks using registered domains to trick users. Becoming increasingly sophisticated in their approach, one in five BEC emails also include the name of the targeted recipient, creating a perceived level of authenticity. The consequences of malicious emails and cybercrime affected 47% of CISOs financially, indicating the importance of education and safety when working online. In 2018 alone, there was US$1.3 billion in losses worldwide due to BEC scams. Defending against email security threats 34 INTELLIGENTCIO www.intelligentcio.com
