Why Employees Keep Falling for Phishing Emails – And What You Can Do About It

Why Technology Alone Can’t Stop Phishing Attacks

Your organization has implemented cybersecurity comprehensively across your IT framework and established strict security protocols. Yet, it still suffers from security incidents. You wonder why?  95% of all data breaches are caused by human error.

Shocked? Don’t be. Monitor, analyze and evaluate your cybersecurity posture. Conduct a root cause analysis. Chances are that your employees or end users are one of the key reasons behind the security incidents.

The purpose of this article is to give readers a ringside view into the human element of cybersecurity, why employees remain the weakest link in cybersecurity, and what you can do about it.

Understanding Human Vulnerability in Cybersecurity

Why are humans so vulnerable to cyberattacks? Why do they keep falling for them? The answer lies in human psychology. Cybercriminals have evolved to exploit cognitive shortcuts like curiosity, fear, and urgency through carefully crafted phishing campaigns. They prey on victims under tight deadlines, leveraging fatigue, fear, and misplaced trust to breach psychological defences.

Another contributing factor is the evolution of workplace tools. The rise of collaboration platforms has introduced new attack surfaces. Cybercriminals now exploit tools like Microsoft Teams, where external users can initiate chats with employees, creating a new entry point for phishing attacks.

A third dimension is the rise of AI, especially generative models, which enable attackers to craft phishing emails that mimic corporate writing styles with uncanny accuracy. These emails no longer resemble the crude, typo-laden messages of the past; they’re clean, credible, and dangerously convincing.

Unfortunately, while we continue to plug systemic security gaps with next-gen security solutions, we overlook the human frailties that hackers and various cybercriminals exploit. These frailties encompass skills-based, knowledge-based, and psychological aspects.

The Psychological Traps That Make Phishing So Effective

• Urgency

  Cybercriminals love to create a good ‘panic’. Panic induces thoughtless decision-making. These are phishing attacks that have tight timelines baked into them or create specific emergencies to pressurize victims into either clicking malicious links or divulging sensitive information.

  Example: An email from a bank asking you to update your password by clicking on a link urgently, emphasizing the fact that you are very late in taking this action; or an email from the IT Team to log into a specific software with company credentials (e.g., Office 365) and benefit from a feature that is critical to the employee’s role.

• Fear

  ‘Fear is the mind killer’, is a quote from Frank Herbert’s seminal SF novel, Dune, written back in 1965. This statement hasn’t lost its relevance irrespective of the scenario. If a person feels threatened, their decision-making is hurried and often impractical. This is a common trigger employed by criminals. 

  Example: You receive an email from your email services provider stating that your account is suspended and that you must immediately enter your login credentials to avoid losing access; a threat of legal action if your credit card bill is left unpaid by the EOD.

• Curiosity

  How often have you taken a decision purely based on curiosity? From the cybersecurity perspective, 2.5% people took a risky action based on curiosity alone. Think of a message that lures you in or a content piece that shocks you so much that you want to know more. There is an element of urgency or fear attached to this phishing campaign, but also a sense of intrigue, and a trust in human nature to take detrimental action.

  Example: You receive an email or a message about an exclusive offer just for you (too good to be true!), or millions of dollars left in an offshore account left by a “Nigerian Prince”.

• Trust & Authority

  Humans may or may not trust easily, but hackers rely on this psychological trigger to deceive them. You receive an email from what appears to be a legitimate organization (bank, software company, etc.), and you follow the instructions in the email, but the twist is that it is a phishing email that has just installed malware on your system. There is also another trigger, which is authority, where an email, message, or interaction creates an impression of superiority and speaks from a position of power.

  Example: Imagine an email from a security vendor who is already providing security solutions to your organization. This is a phishing email, and before you realize it, your trust in the brand that your organization is already asking for makes you want to click on it.

• Excitement & Greed

  These are triggers as old as time. How many cases have you heard where people have lost a fortune because of greed? Scammers are well aware of a person’s propensity to fall victim to emails or messages that proclaim lottery winnings, discounts or even ask them to invest in low-investment, high-return schemes. The focus is on creating excitement and playing on a widespread human trigger – greed.

  Example: You get a mail saying you have just won a lottery and to claim it, you must share bank account credentials, or pay some money to get that amount; or there is a minimal time offer that again ask you to pay a certain amount of cash quickly to qualify and not miss out on this offer.

Common Mistakes That Keep Phishing Emails Successful

We have discussed the psychological or human triggers that hackers exploit, but what are the errors that allow attackers in? This is another important question that needs an answer, because that’s the key reference point for a solution.

• Weak Passwords
  

  In 2024, over 2.8 billion passwords were on sale! This figure is illustrative of the fact that compromised passwords are a huge problem and one of the key reasons for data breaches. Weak passwords, or passwords that have been reused time and again, are a low-hanging fruit for attackers. With 22% of data breaches resulting from stolen credentials, weak passwords are a gap that needs to be plugged.

• Emotional Click

  We recognize that phishing attacks pose a problem. We also understand the different ways attackers can exploit psychological triggers to push us into actions we wouldn’t normally take, despite our awareness. However, victims of phishing often find themselves clicking on malicious links. This remains a concern that must be addressed.

• Social Engineering

  Victims are being eased into social engineering attacks, especially with the arrival of AI, where deepfakes are getting more prevalent and voice impersonation is becoming even more difficult to crack. So, intended victims receive a phone call that sounds genuine, or a request that seems reasonable and is nothing out of the ordinary. This is how intended victims move through the attack funnel, letting their guard down, until they commit the cardinal sin – sharing valuable information.

• Mismanagement and Negligence

  Consider an employee who must follow specific procedures to minimize risk in their actions. However, these procedures are not followed. For instance, every time a request for a money transfer in a travel card is received at the travel desk, it must be signed off by the accounts department. If the amount exceeds predetermined levels, further authorization from a senior manager is a must. If the person doesn’t follow this procedure, there is a chance that the phishing attack will succeed. Another scenario is that of an email sent to the wrong address. A simple and honest mistake, but it proves to be deadly, because according to a report, 18% of breaches are caused by email misdeliveries. 

• Malicious Insiders

  Breaches can sometimes result from deliberate sabotage. Over 80% of organizations reported at least one insider attack in 2024. This is a significant figure, indicating the need to adopt a zero-trust approach towards employees. While many human errors are inadvertent or unknowing, other errors are intentional and seek to create a way for attackers to enter the system from within.

The Necessity of Cybersecurity Awareness Training

Security awareness training for end-users, whether employees or individuals, is essential because human error leading to security incidents remains a major issue. Employees, therefore, should be equipped with the practical knowledge needed to protect their organization’s sensitive data and information, and they can only achieve this by avoiding phishing attacks and refraining from unintentional mistakes. Cyber awareness training educates employees about the threat landscape, potential vulnerabilities, spotting red flags and adopting habits that ensure compliance with the organization’s security policies.

Another reason why security awareness training is necessary is to comply with specific industry regulations like GDPR, HIPAA and others.

What an Effective Awareness Program Looks Like – 5-Step Framework

1. Leadership Buy-In
   The global average cost of a data breach is USD 4.9M. This figure is significant and therefore the C-Suite cannot take cybersecurity or its awareness training lightly. Rope in the leadership for these programs; when it comes to establishing a culture of security, you must employ a top-down approach, where the top executive becomes an advocate for cybersecurity awareness, approves budgets, and is involved in formalizing roles and strategy execution. Top-down reinforcement is the key.
2. Assign Ownership
   Your cybersecurity awareness team can be integrated into the larger cybersecurity team, and there should be a leader who has full ownership of the project. Consider cybersecurity awareness as a vital part of business transformation, not merely about developing security training modules for business users.
3. Assessment of Security Posture
   You will first need to know where your employees stand in terms of security awareness. Conduct a short quiz or certification program to gain a clearer understanding of their awareness level. This will help you design the right program with the right KPIs.
4. Regular Training
   Your organization will fail if you treat this as a one-off event. You need to establish a regular training schedule and consistently launch phishing simulations. More importantly, you must ensure that cybersecurity guidance extends beyond technical aspects to become more human-centric, meaning everyone should understand the nature of threats and why preventing them is so crucial. Use short videos, quizzes, and bite-sized learning modules to keep engagement high. Cybersecurity education should regularly reach users’ inboxes.
5. Monitoring, Measuring and Refining
   Don’t just provide security awareness training to be compliant. Make sure you filter out the noise to understand whether your training delivers tangible value. You must measure click rates in phishing simulations, the number of incidents reported by employees, training completion rates, and password hygiene. These KPIs will give you clear visibility into the success rates of the training programmes and whether adjustments are needed.

Pairing Employee Training with Technical Safeguards

While training employees to spot and respond to threats is a vital part of cybersecurity, it cannot exist in a silo. Your organization must also implement security solutions like anti-phishing solutions that identify and remove suspicious links before they land, or sandbox environments that isolate and examine unknown attachments. Also, make use of email authentication protocols such as SPF, DKIM, and DMARC to help verify sender legitimacy, closing off easy paths for impersonation.

Enterprises now reinforce their email authentication stack with Verified Mark Certificates (VMC) and Common Mark Certificates (CMC). These certificates enable brand logos to appear directly in recipients’ inboxes, proving that the sender’s identity has been verified by a trusted Certificate Authority. By visually confirming authenticity before an email is even opened, Mark Certificates reduce click-throughs on spoofed messages and boost confidence in legitimate communication.

When these systems are working well, users are less likely to be overwhelmed by false alarms or obvious scams, which means awareness training can focus on the subtler, more targeted threats that do get through.

Conclusion

Humans are often seen as the weakest link, but they can just as easily become a second line of defense, a human firewall that catches what technology misses. When individuals understand the stakes, they’re trained not just to follow rules but to think critically and stay alert, that firewall grows stronger. It doesn’t happen overnight. But with the right mix of education, awareness, and shared responsibility, employees start becoming active protectors of the organization they work in and the systems they use.
