Not all cyber-attacks are as sophisticated or widespread as this month’s Wannacry ransomware attack. On most occasions cyber security breaches are in fact down to human factors. For example, the 2016 Cyber Security Intelligence Index from IBM found that 60 per cent of all attacks were carried out by insiders. Of these, three quarters had malicious intent whilst one-quarter involved inadvertent actors. One of the most common ways that cyber security is compromised through what is known as phishing emails, messages, or phone calls.
