[INFOGRAPHIC] Q2 2023 Top-Clicked Phishing Test Results Favor HR-Related Subjects



KnowBe4's latest reports on top-clicked phishing email subjects have been released for Q2 2023. We analyze 'in the wild' attacks reported via our Phish Alert Button, top subjects globally clicked on in phishing tests, top attack vector types, and holiday email phishing subjects.

 HR-Related Subjects Represent Half of Malicious Emails Clicked

This last quarter's results reflect the popularity of HR-related email subjects such vacation policy notifications, dress code changes, and past due training alerts that can affect end users’ daily work.

“The threat of phishing emails remains as high as ever as cybercriminals continuously tweak their messages to be more sophisticated and seemingly credible, now with the help of GenAI and returning to the office ,” said Stu Sjouwerman, CEO, KnowBe4. “The trend of phishing emails revealed in the Q2 phishing report is especially concerning, as 50% of these emails appear to come from HR – a trusted and crucial department of so many, if not all organizations. These disguised emails take advantage of employee trust and typically incite action that can result in disastrous outcomes for the entire organization. New-school security awareness training for employees is crucial to help combat phishing and malicious emails by educating users on the most common cyber attacks and threats. An educated workforce is an organization’s best defense and is essential to fostering and maintaining a strong security culture.”
