Dangerous Attacks in Phishing Emails With Business, IT and HR Focus on Increase


KnowBe4, the provider of security awareness training and simulated phishing platform, has announced the results of its Q3 top-clicked phishing report.

“Social engineering attacks continue to be one of the top ways malicious hackers breach organizations and/or cause damage,” said Stu Sjouwerman, CEO, KnowBe4. “We are seeing a continued increase in phishing, including more use of common HR types of communications and less reliance on obvious social media phishing campaigns. By equipping security professionals with more data on likely tactics and templates used by cybercriminals executing phishing attacks, infosec professionals can strengthen their human firewall. Now more than ever, end users need to remain vigilant and remember to stop and think before they click.”

Top 10 Email Categories Globally:

  6. Coronavirus/COVID-19 Phishing

Top phishing email subjects were also broken out, comparing those in the U.S. to those in Europe, the Middle East and Africa (EMEA). In Q3 2021, KnowBe4 examined tens of thousands of email subject lines from simulated phishing tests. In the U.S., most of the email subjects appear to originate from the users’ organization. However, in EMEA, the top subjects are related to users’ everyday tasks. The organization also reviewed ‘in-the-wild’ email subject lines that show actual emails users received and reported to their IT departments as suspicious. The results are below.
