Phishing: the simple human hack that exploits your team

Phishing isn’t new, but it’s more dangerous than ever. Despite decades of advancements in cybersecurity tools, phishing remains one of the most effective methods for breaching businesses. Why? Because phishing doesn’t target firewalls. It targets people.

As a decision-maker, you need more than a surface-level understanding of phishing. You need to know how it works, why it works, what it costs, and what you can do about it. This post will break it all down for you.

What is phishing?

Phishing is a type of cyber-attack that manipulates people into giving away sensitive information, like login credentials or financial data. It’s social engineering, not system exploitation.

A classic example: An employee receives an email that looks like it’s from Microsoft or your finance director. It includes a link to “verify login details.” One click, and the attacker gains access to your systems.

Attackers don’t need to be technically gifted at all – just convincing.

Why phishing still works

Phishing is hard to stop because it preys on human behaviour:

• Curiosity: “What’s this invoice?”
• Trust: “It looks like it’s from our CEO.”
• Urgency: “Act now or lose access.”

Security software can block malware, but it can’t stop someone clicking a dodgy link if they believe it’s legitimate. That’s the real challenge, and the reason phishing bypasses even the best IT infrastructure.

Common types of phishing (and why they matter to you)

Most businesses assume phishing means dodgy emails. In truth, it comes in many forms:

• Email Phishing: Fake emails impersonating trusted brands or colleagues.
• Spear Phishing: Highly targeted, based on publicly available info (e.g. your LinkedIn profile or press releases).
• CEO Fraud (Whaling): Impersonates senior leadership to trick finance or HR into releasing funds or data.
• Vishing: Voice phishing. A call from “HMRC” or “Microsoft” urging immediate action.
• Smishing: Phishing via SMS. Includes delivery scams or banking alerts.
• Angler Phishing: Phishing over social media through fake support accounts.
• Watering Hole Attacks: Legitimate websites (often industry-specific) are hijacked to serve malware.

Each method can be tailored to exploit your staff’s behaviour, access level, or industry norms.

The organisational risk: it’s not just about spam

Phishing isn’t just about spam clogging inboxes. It’s a top cause of:

• Data breaches
• Ransomware infections
• Credential theft
• Financial fraud
• Brand reputation damage

According to the FBI, phishing was the most reported cybercrime in 2020, with over 240,000 incidents – more than double the year before. And it’s getting more sophisticated every year.

Verizon’s 2021 Data Breach Report showed that 96% of phishing attacks arrive by email, but the biggest concern isn’t the delivery – it’s the result. One click can lead to system-wide compromise.

The cost of a click

It’s easy to see a phishing email as an IT problem, but the real cost hits your bottom line:

• Downtime: Systems offline = revenue lost
• Fines: If customer data is exposed, GDPR penalties follow
• Ransom payments: If ransomware is involved, recovery can cost six figures
• Reputational damage: Loss of trust, especially in regulated industries

You can invest in antivirus and firewalls, but if your people aren’t trained or protected, you’re  still exposed.

What can you do? Practical steps for leaders

It’s not about finding one silver bullet. It’s about building layered, strategic resilience:

1. Security Awareness Training – Teach your team how to spot red flags. Regular, engaging training (not boring tick-box modules) dramatically reduces click rates.

2. Email Security & Filtering – Invest in tools that flag suspicious emails, check links in real-time, and isolate attachments in a sandbox environment.

3. Phishing Simulations – Test your own team. Regular simulations show who’s vulnerable and help create a culture of caution.

4. Multi-Factor Authentication (MFA) – If a password is stolen, MFA can stop attackers getting any further.

5. Incident Response Plan – Have a clear, tested process for what to do if someone falls for a phishing attempt. Speed is everything in damage control.

6. Password Managers – Employees often reuse passwords. A password manager enforces strong, unique credentials—and reduces the chance of reuse attacks.

7. Regular Backups – Ransomware often enters via phishing. If your data is backed up, you can recover quickly and avoid paying attackers.

A leadership responsibility

If you’re a director, founder, or department head, your support matters. Your staff will take cybersecurity seriously if they see you taking it seriously. In fact, one of the easiest ways attacker gain credibility is when they impersonate you!

Final thought: be proactive, not reactive

Cybersecurity isn’t about if you’ll be targeted. It’s about when and whether you’re ready. The good news? You don’t need a massive budget to start protecting your people. But you do need a strategy. Not just antivirus software, but a people-first approach to cyber safety.

Start with awareness. Plan for incidents, and above all, stay vigilant.
