Cybercriminals are now zeroing in on HR departments. In Q2 2025, HR-themed phishing emails ranked among the most-clicked in simulations by cybersecurity firm KnowBe4. These deceptive emails, often mimicking colleagues or HR processes, exploit employee trust to steal sensitive data. With tactics evolving rapidly, HR leaders must act fast to safeguard their organizations. Here’s how these scams work and what HR can do to fight back.
Why HR-Themed Phishing Emails Succeed
Phishing emails disguised as HR communications are dangerously effective. They use familiar subjects like vacation policies, W-4 updates, or performance reviews to lure clicks. KnowBe4’s Q2 2025 report found employees interact more with emails impersonating colleagues, with nearly 1 in 3 users clicking suspicious links.
“These emails take advantage of employee trust,” says Stu Sjouwerman, CEO of KnowBe4. “Cybercriminals adapt strategies at an alarming speed, targeting the foundation of organizational trust.” This trust makes HR-themed phishing emails a top threat. For example, Sarah, a fictional HR assistant, shared, “I clicked a link about a dress code update. It looked so real, but it led to a fake login page.”
The emotional pull of HR-related topics fuels their success. Layoff notices or benefits updates spark urgency, prompting impulsive clicks. “Phishing attempts with HR subject lines cause employees to react before thinking,” says Aamir Lakhani, a cybersecurity expert at Fortinet. Industries facing layoffs are especially vulnerable, as employees fear job loss and act quickly.
Emerging Threats: QR Code Phishing and Beyond
Cybercriminals are getting creative. KnowBe4’s report highlights a rise in QR code phishing, or “quishing,” where malicious QR codes hide in emails about MFA migrations or password expirations. Scanning these codes leads to fake websites that steal credentials.
“QR codes are a growing concern,” Sjouwerman warns. “They’re embedded in seemingly legitimate HR emails, making them hard to spot.” This tactic bypasses traditional email filters, as codes appear harmless until scanned.
Other phishing methods include fake remote work forms or compliance training links. In 2023, IBM reported phishing as the leading cause of corporate data breaches, with HR-themed emails driving much of the success. John, a fictional office manager, recalled, “I scanned a QR code about MFA setup. It took me to a login page that stole my credentials. I had no idea.”
How HR Can Protect Against Phishing Scams
HR leaders must prioritize cybersecurity to combat these threats. First, invest in regular employee training. KnowBe4’s data shows trained employees are less likely to fall for phishing scams. Teach staff to spot red flags like generic greetings or suspicious links. “Hover over links before clicking,” advises Erich Kron, a KnowBe4 security advocate. “If the URL looks odd, don’t trust it.”
Second, collaborate with IT to strengthen defenses. Use advanced email filters to catch phishing attempts early. Multi-factor authentication (MFA) adds another layer of protection, even if credentials are stolen.
Finally, simulate phishing attacks to test employee awareness. KnowBe4’s Q2 simulations revealed HR-themed emails consistently fooled workers, underscoring the need for ongoing drills. “Training isn’t a one-time fix,” Sjouwerman emphasizes. “Cybercriminals evolve, so must we.”
HR departments hold sensitive data, making them prime targets. By fostering a culture of vigilance, HR can reduce risks. Encourage employees to verify emails directly with HR or IT before acting. Regular updates on phishing trends also keep staff informed. The rise of HR-themed phishing emails demands action. From emotional manipulation to QR code tricks, cybercriminals exploit trust in HR. With robust training, IT collaboration, and simulated attacks, HR leaders can protect their workforce. Stay proactive. The next email could be a trap.
