What is Phishing?
In today’s increasingly digital world, much of what we do — whether for business or pleasure — is carried out online. This surge in online activity has resulted in a massive explosion in cybercrime.
Cybercrime has become a powerful tool for criminals seeking to steal our personal data and extort money. The speed, anonymity, and convenience of the internet have enabled criminals to launch highly targeted attacks with very little effort.
According to the 2025 Cifas/Global Anti-Scam Alliance report for the UK, scamming and fraud against consumers reached about £9.4 billion over the past 12 months.
The most successful and dangerous of all cyber-attacks is phishing. Research has found that 91% of all cyber-attacks start with a phishing email.
Phishing continues to be the most common form of cyber-attack due to its simplicity, effectiveness, and high return on investment. It has evolved from its early days of tricking people with tales of Nigerian princes or urgent pleas for medical help. The phishing attacks taking place today are sophisticated, highly targeted, and increasingly difficult to spot.

Types of Phishing Attacks
Phishing attacks come in many different forms but the common thread running through them all is their exploitation of human behaviour. The following examples are the most common forms of attack used.
How to Spot Phishing Attacks
Identifying phishing emails has become much harder as criminals have grown more sophisticated. Today’s emails are often well written, personalised, and use the logos and language of trusted brands, making it difficult to tell them apart from legitimate messages. Despite this, there are still some warning signs that can help alert us to a phishing attempt.


Tips for Identifying Phishing Scams
A mismatched URL
One of the first things to check in a suspicious email is the validity of a URL. If you hover your mouse over the link without clicking on it, you should see the full hyperlinked address appear. Despite seeming perfectly legitimate, if the URL does not match the address displayed, it is an indication that the message is fraudulent and likely to be a phishing email.
The email requests personal information
A reputable company will never send out an email to customers asking for personal information such as an account number, password, pin or security questions. If you receive an email requesting this information, it is likely to be a phishing email and should immediately be deleted.
Poor spelling and grammar
Cybercriminals are not renowned for their top-quality spelling and grammar. Whenever legitimate companies send out emails to customers they are often proofed by copywriters to ensure the spelling and grammar is correct. If you spot any spelling mistakes or poor grammar within an email it is unlikely to have come from an official organisation and could indicate the presence of a phishing email.
The use of threatening or urgent language
A common phishing tactic is to promote a sense of fear or urgency to rush someone into clicking on a link. Cyber criminals will often use threats that your security has been compromised and that urgent action is required to remedy the situation. Be cautious of subject lines that claim your account has had an “unauthorised login attempt” or your “account has been suspended”. If you are unsure if the request is legitimate, contact the company directly via their official website or official telephone number.
Unexpected correspondence
If you receive an email informing you that you have won a competition you did not enter, or a request that you click on a link to receive a prize, it’s highly likely to be a phishing email. If an offer seems too good to be true, it usually is!
How to protect yourself against Phishing Attacks
1. Avoid Clicking Suspicious Links
Phishing scams often trick people into opening emails or clicking links that appear to come from legitimate sources. These links may direct you to fake websites that steal personal information or infect your computer with malware. Legitimate businesses will never ask you to enter or update sensitive information via email.
2. Educate Staff
Even the strongest security systems are vulnerable if employees unknowingly provide information to cybercriminals. Regular training helps staff recognise phishing attempts and understand their role in preventing attacks. Simulated phishing tests can also reinforce awareness and strengthen your first line of defence.
3. Be Careful What You Share Online
Social media and public profiles provide cybercriminals with information to craft highly targeted phishing attacks. Limit the personal data you share, use privacy settings, restrict access to unknown users, and use strong passwords to reduce your risk.
4. Verify Website Security
Before entering personal information, check that a website is secure. Look for URLs starting with “https” and a padlock icon in the address bar. These indicate the site uses SSL encryption, keeping your data safe.
5. Install and Update Anti-Virus Software
Anti-virus software helps detect threats and block unauthorised access. Keep your programmes updated to protect against vulnerabilities in older software versions.
