Last week, IBM and The Ponemon Institute released their annual Cost of a Data Breach Report. For the past 15 years, the report has highlighted recurring and emerging factors that contribute to the cost of data data breaches, as well as the root causes of those breaches. One of the key findings in this year’s report is the fact that human factored cyber attacks not only make up a large percentage of the all malicious attacks, but also are incredibly costly to businesses that suffered breaches. This only confirms the importance of cyber awareness training for employees to limit the risk of a human factored attack.

There are many different causes of a data breach, some of which are merely accidental. However, according to this year’s report, malicious attacks now make up 52% of all breaches. This didn’t used to be the case. In fact, malicious attacks have seen a 24% growth rate in just six years.  Malicious attacks are also the most expensive, costing businesses an average of $4.27 million. That’s nearly $1 million more than all other causes of a breach.

Given the frequency and cost of malicious attacks, it’s important to look closer at the different threats that account for the rise in malicious attacks — and the data is surprising. While expected threats such as system vulnerabilities and malicious insiders are certainly present, human factored cyber attacks take up a large chunk of all malicious attacks. Threats ranging from phishing attacks, to business email compromise, to social engineering and cloud misconfigurations are all rooted in human rather than technical vulnerability, and account for 41% of all malicious attacks leading to data breaches.  Indeed this report correlates with what was presented in the Verizion 2020 Data Breach Investigations Report.

Human factored cyber attacks aren’t something you can protect yourself against strictly through technically safeguards. Instead protecting against these vulnerability requires working with employees, establish proper quality control protocols, ensuring your have the right expertise on your team and using cyber awareness training to help build safer online habits.

As a Fortune 100 CISO once told me, “at the end of the day, every cyber incident starts with someone making a decision.”
