In an era where data is the new oil, cybercriminals have refined their tactics, exploiting human psychology to bypass even the most advanced defences. The latest Cyber Security Breaches Survey 2024 shows a stark reality: 84% of UK businesses reported phishing as the most prevalent type of attack they faced.

In this guide, we break down the key indicators of a phishing attempt and offer practical, actionable steps to strengthen your security and protect your organisation from these increasingly sophisticated threats.

Understanding Phishing: What Is It and Why Does It Work

At its core, phishing is a social engineering technique where attackers pose as trusted entities, manipulating individuals into revealing sensitive information such as passwords, financial details, or even access credentials. It’s a strategy that has proven effective time and again, evolving into several distinct forms.

The most common form, email phishing, often mimics a recognisable company or colleague. These emails are crafted to look genuine, urging recipients to click a link or download an attachment, unknowingly compromising their security. A more targeted variation is spear phishing, which zeroes in on specific individuals, usually those in high-level positions like executives or directors. Here, the attacker tailors the message to the victim, using details that make the deception even harder to detect.

Phishing has also diversified beyond email. Smishing (SMS phishing) and vishing (voice phishing), both of which rely on phone-based communications, exploit the urgency and immediacy of text messages or phone calls, creating a false sense of panic to manipulate victims into divulging information.

A more insidious approach is clone phishing, where a legitimate email is replicated, but its content is altered to include malicious links or attachments. Having seen the original email before you are more likely to trust this altered version. This method relies on the trust built by the original email, making it especially effective.

Phishing plays on core human emotions—fear, urgency, and trust. This psychological manipulation is what makes phishing so dangerous and why it continues to be a significant threat in the digital landscape.

What to Watch Out for in a Phishing Attack

Phishing is effective because it preys on human instincts, exploiting emotions like urgency and trust and getting you to act before you can think.

These attacks are designed to slip under the radar, mimicking familiar sources and bypassing logical defences. But while the methods may be subtle, the warning signs are often clear once you know what to look for.

Let’s dive into the key red flags you should be aware of and that should raise your suspicion.

• Suspicious Sender Addresses: Always scrutinise the sender’s email domain carefully. Attackers often use addresses that look almost identical to legitimate ones, swapping characters to trick the eye e.g., using @micr0soft.com instead of @microsoft.com. 

• Generic Greetings: Phishing emails usually lack personalisation. Instead of addressing you by name, they use vague, impersonal phrases like “Dear Customer” or “Dear User,” making the message feel less tailored. 

• Urgent Language or Threats: Phishers often try to create a sense of urgency or panic. Phrases like “Your account will be locked in 24 hours” are designed to pressure you into reacting quickly without taking the time to verify the message. 

• Unexpected Attachments or Links: Be cautious if the email contains an unexpected attachment or a link you weren’t anticipating. It’s good practise to hover your mouse over the link to preview the URL before clicking—this can reveal whether it’s pointing to a suspicious or unfamiliar site. 

• Poor Grammar and Inconsistent Branding: Keep an eye out for spelling mistakes, blurry or low-quality logos, and strange formatting. These inconsistencies can be telltale signs that the email didn’t come from a legitimate source. 

• Requests for Sensitive Information: Reputable organisations will never ask for passwords, credit card numbers, or other personal details via email. If you’re asked to provide sensitive information, it’s almost certainly a phishing attempt.

By familiarising yourself with the common indicators of phishing, you can detect these attempts early and prevent them from causing harm.

Your Action Plan for Suspected Phishing Attempts

Armed with the knowledge of phishing red flags, you’re already a step ahead in the fight against cyber threats. However, recognising the signs is only half the battle. The real challenge lies in your response. Knowing how to act quickly and effectively can be the difference between a contained incident and a full-scale breach. If you suspect you’ve come across a phishing email, here’s your action plan to follow.

• Don’t Click on Anything: It only takes one wrong click to compromise your system. Refrain from clicking on any links or downloading attachments before verifying their authenticity. 

• Report the Suspicious Email Immediately: Get in touch with your IT or cybersecurity team as soon as possible. The faster they’re alerted, the quicker they can investigate and respond to the threat. 

• Contain the Issue: If you fall foul of a phishing attempt, disconnect any affected devices from your network as soon a s possible. This step helps prevent the spread of potential malware or unauthorised access. 

• Review and Reflect: Once the immediate risk is managed, take a time to analyse the incident. Understanding how the phishing email bypassed your defences can offer valuable insights for strengthening your security measures going forward. 

Building a Strong Defence Against Phishing

Recognising phishing attempts is a crucial first step, but prevention is key to truly defending your organisation. As cybercriminals refine their tactics, a reactive approach is no longer enough. A strong, proactive strategy is vital—one that combines employee awareness with advanced security measures. Here’s how you can build a resilient defence and stay one step ahead of phishing threats.

Train Your Team Regularly: Phishing awareness sessions and simulated attacks help keep your staff sharp, equipping your team with the knowledge they need to identify phishing attempts quickly and accurately.

Turn on Multi-Factor Authentication (MFA): MFA adds an extra lock on the door. Even if hackers steal a password, they’ll hit a wall when MFA is enabled. 

Establish a Phishing Response Plan: Develop a clear, step-by-step protocol for reporting suspected phishing emails and responding to potential incidents. This ensures a swift, coordinated approach when threats arise.

The Power of Vigilance

Phishing attacks are becoming more sophisticated by the day, and vigilance is the name of the game. By educating your team and staying alert to the warning signs, you can greatly reduce the risk of falling victim. It’s about building a habit of caution—always trust your instincts and verify before clicking.
