These subject lines are the most clicked for phishing
The most successful email lures don’t promise riches, but issue imminent cybersecurity warnings or urgent office messages, a report reveals.
By now, even the least-seasoned email user knows not to open messages from Nigerian princes or vacationing “friends” desperate for an emergency loan.
But bad actors have become increasingly clever in phishing attempts. KnowBe4, which provides security awareness training, revealed the most clicked subject line in a fourth-quarter report.
The most-effect lure, the firm found, was an urgent message to immediately check a password, with 39% of users falling for the ruse.
“With more end users becoming security-minded, it’s easy to see how they fall forrelated to changing or checking their passwords,” said Stu Sjouwerman, KnowBe4’s CEO, in a release.
And just because you work in tech, doesn’t mean you’re immune. “These subject lines are very effective against tech pros as well,” said Erich Kron, security awareness advocate, KnowBe4.
“Tech professionals tend to become comfortable with email and technology, and therefore can be less careful than people who are more suspicious of everything,” Kron said. “When speaking to tech pros about emails they fell for, they seem to realize that they made an error by clicking much faster than non-technical employees, however, it’s often too late at that point.”
Buthave also effectively tricked users, notably when LinkedIn is the subject—55% were successful, with Facebook following at 28%.
“Not surprisingly, LinkedIn email subjects top the social media list for Q4 in a pretty big way. Q4 is a time where people are setting resolutions for the following year, and this often involves a job search. Activity related to LinkedIn tends to spike in this quarter, meaning people are more likely to view and click these emails.”
Research for the report was gathered through an examination of thousands of email subject lines from simulated phishing tests.
KnowBe4 also reviewed “in-the-wild” email subject lines, which added previously received email as an additional incentive to open, as well as company emails reported to IT departments as suspicious.

Email users “should be especially cautious if an email seems too good to be true, such as a giveaway,” Sjouwerman said. “As identifying phishing attacks from legitimate emails becomes trickier, it’s more important than ever for end-users to look for red flags, and think before they click.”
