Mike Rogers, the former chairman of the House Intelligence Committee, spoke last week at the U.S. Chamber of Commerce’s cybersecurity summit about phishing attacks, as the next big attack vector, and their increased potential to dramatically impact an organization’s economic loss and liability. He noted that cybercriminals, particularly those with nation-state backing, have created such sophisticated email phishing attacks that it is nearly impossible to defend against malware infections.

Rogers also cited that the availability of personal information on social media sites as driving advanced social engineering by cybercriminals, who use the information to create highly personalized phishing schemes. Rogers said sophisticated phishing emails are responsible for more than 90% percent of successful cyberattacks.

In addition to the top 10 most-clicked general email subject lines, KnowBe4 also evaluated the top 10 global social networking subject lines for Q3 2017. These subject lines represent simulated phishing tests that KnowBe4 clients sent to a user’s inbox as if they were coming from a social media site and reflecting some sort of account activity. Following in the footsteps from Q2, four of the top 10 spots again went to LinkedIn, which users often have tied to their work email addresses. This, too, plays into the human psyche, as people want to connect and manage their reputation on their social networking sites so often open and interact with emails from the sites. LinkedIn poses an interesting dilemma for organizations and their employees as it is important to both have an updated and active presence on LinkedIn, yet the platform is obviously highly targeted by cybercriminals for social engineering and phishing activities.

“By playing into the human psyche, hackers will successfully continue to infiltrate an organization through a phishing email. The level of sophistication hackers are now using makes it nearly impossible for a piece of technology to keep an organization protected against social engineering threats,” Perry Carpenter, chief evangelist and strategy officer at KnowBe4, said. “Phishing attacks are smart, personalized and timed to match topical news cycles. Businesses have a responsibility to their employees, their shareholders and their clients to prevent phishing schemes. KnowBe4 has a proven track record of helping them do just that.”
