13 Phishing Warning Signs
Here are the top 13 signs that an email might not be legitimate.
1. Unusual Sender Addresses & Domains:
When inspecting emails, always check sender addresses to identify any irregularities, as phishing attempts often employ variations or misspellings of legitimate domains. This is a crucial step in understanding how to check an email for phishing.
2. Generic Greetings:
Legitimate emails from reputable sources typically use personalised greetings, addressing recipients by their names. If you come across an email with a generic greeting like "Dear Customer," exercise caution, as this is one of the email security tips to be mindful of.
3. Unexpected Attachments or Links:
If you receive an email with unexpected attachments or links urging urgent action, avoid clicking directly. Before interacting with any attachments or links, independently verify the sender's legitimacy.
4. Misspelled Words and Poor Grammar:
Phishing emails often contain spelling mistakes and grammatical errors, which can be significant phishing warning signs. Pay attention to language quality as it can indicate the legitimacy of the communication.
5. Urgent Calls to Action:
Be cautious when an email demands urgent responses, as this is a key phishing warning sign. If in doubt about what to do with suspicious emails, take the time to independently verify their legitimacy before providing any information.
6. Emails Requesting Sensitive Data:
If you receive an email requesting sensitive information like login credentials or payment details, take immediate action on what to do if you have been phished. Independently verify such requests through a trusted channel before responding.
7. Unsecured Websites:
Always check for "https://" in the URL and a padlock symbol in the address bar when following links from emails to protect against phishing. This helps identify secure websites and avoids sharing details with scammers.
8. Unusual Email Structure:
Be wary of emails with unusual formatting or inconsistent designs, as these can be indicators of phishing attempts. Examine the email structure for irregularities and grammatical errors.
9. Suspicious Pop-Up Windows/Notifications:
If you encounter unexpected pop-up windows within emails, be cautious, as legitimate organisations typically do not use them to request information. Recognising suspicious pop-up windows is crucial in identifying phishing attempts.
10. Mismatched URLs:
Hover over links to preview the destination URL before clicking, part of the process of how to check if an email address or website URL is spam. If the displayed link differs from the expected one, it could be a phishing attempt.
11. Fake Logos and Branding:
Phishing emails often feature counterfeit logos and branding. To detect phishing attempts, compare the images to the official ones from the legitimate organisation, paying attention to the quality of the branding.
12. Unusual CEO Emails or Whaling:
These emails are usually from a hacker impersonating a top executive at your company hoping to steal money or private information from employees within the same company. This is also known as “CEO Fraud.”
13. Too Good to Be True Offers:
Be sceptical of emails promising extraordinary deals or offers, as they may be phishing attempts. Verify the authenticity of such offers through official channels.

- Spear Phishing:
In spear phishing, attackers target specific individuals or organisations. The attackers gather information about the target, such as their interests, relationships, and work roles, to create personalised and convincing phishing messages. Spear phishing can often be identified via bad grammar. This type of phishing often requires more research but can be highly effective.
- Phishing Emails:
Phishing emails are the most common form of phishing. Attackers send deceptive emails that appear to be from legitimate sources, such as banks or government agencies, to trick individuals into providing sensitive information or clicking on malicious links.
- Vishing (Voice Phishing):
Vishing involves using phone calls to trick individuals into providing sensitive information. The attackers may use caller ID spoofing to appear as a trusted entity, such as a bank or government entity to add to their legitimacy. Make sure to look up suspicious phone numbers before revealing any confidential information.
- SMS Phishing:
Smishing, or SMS phishing, involves phishing attacks conducted through text messages. Attackers send deceptive messages claiming to be from trusted sources, often containing links or phone numbers, with the aim of tricking recipients into providing sensitive information or clicking on malicious links.

Whaling or CEO fraud targets high-profile individuals within organisations, such as executives or CEOs. Attackers aim to deceive these individuals into authorising financial transactions or revealing sensitive information by posing as a trusted colleague or business partner.
- Business Email Compromise (BEC):
BEC attacks involve compromising business email accounts to conduct fraudulent activities. Attackers gain access to an email account, often through social engineering or phishing, and use it to impersonate executives or employees to initiate financial transactions or gain unauthorised access.
- Angler Phishing:
Angler phishing involves exploiting social media platforms to target individuals. Attackers create fake profiles or pose as trusted contacts to manipulate victims into revealing personal information or clicking on malicious links.
- Search Engine Phishing:
In search engine phishing, attackers manipulate search engine results to lead individuals to malicious websites. Victims may think they are clicking on legitimate links, but they end up on phishing sites designed to steal their credentials or deliver malware.
- Man-in-the-Middle (MitM) Attacks:
In MitM attacks, hackers intercept and potentially alter communication between two parties without their knowledge. This can include intercepting login credentials or sensitive information exchanged between the user and a legitimate website.
- What's the best way to detect a phishing email?
Detecting phishing emails involves a combination of vigilance and attention to key indicators. First, scrutinise the sender's email address for any subtle variations or misspellings. Verify the authenticity of the sender and be cautious of unfamiliar or unexpected sources. Examine the content for poor grammar, spelling errors, or unusual language, as legitimate organisations maintain high communication standards. Avoid clicking on suspicious links by hovering over them to preview the destination URL. Be wary of emails creating a sense of urgency and demanding immediate action. Check for personalisation, as legitimate emails often address recipients by name. Carefully examine unexpected attachments, and never provide sensitive information in response to email requests. Trust your instincts; if something seems off, independently verify the email's authenticity before taking any action. Staying informed about common phishing tactics and regularly updating cybersecurity knowledge enhances the ability to identify and respond to phishing threats effectively.
