AI-Generated Phishing: 6 Ways to Protect Your Business

91% of cyberattacks start with a single email.

Thanks to AI, that email is no longer obvious or sloppy. It’s polished, personalised, and terrifyingly convincing. Even senior executives are 23% more likely to fall for AI-driven phishing attacks, making leadership a prime target.

Traditional warning signs – spelling errors, odd greetings, generic messages – no longer apply. Today’s AI phishing emails mimic your colleagues, your CEO, and trusted partners perfectly. One wrong click could cripple your business. In fact, 60% of companies don’t survive six months after a major cyberattack.

So how do you fight back? Delta 365 recommends a layered, proactive approach. Here are 6 ways to protect your business from AI-generated phishing threats.

1. Multi-Factor Authentication (MFA)

Passwords alone are no longer enough. MFA adds an extra layer of security by requiring two or more verification methods – something you know (password), something you have (token or phone), or something you are (biometric).

Even if a phishing email captures a password, MFA prevents attackers from accessing sensitive accounts. For critical systems, MFA isn’t optional – it’s essential.

2. AI-Powered Email Security

AI has levelled the playing field for cybercriminals – so why not use it for defence? Modern email security platforms use machine learning to detect subtle anomalies, such as:

• Suspicious sender patterns

• Domain spoofing attempts

• Requests that deviate from normal business behaviour

By constantly learning from attempted attacks, these systems adapt faster than humans can, giving your organisation a crucial first line of defence.

3. Continuous Security Awareness Training

Your people are both your strongest defence and your greatest vulnerability. AI phishing attacks are personalised and context-aware, meaning anyone could be fooled – even your most experienced team members.

Best practice: Conduct ongoing, realistic phishing simulations. Teach employees to:

• Pause before clicking links or attachments

• Verify unusual requests through a trusted second channel

• Recognise subtle signs of AI-crafted deception

Result: Teams learn to think critically, slowing attackers down and reducing the likelihood of successful breaches.

4. Behavioural Monitoring

Attackers don’t always hit immediately. Compromised accounts often behave subtly at first. Behavioural analysis tools monitor user activity, including:

• Login locations and times

• File access patterns

• Email sending habits

Any deviation triggers alerts for investigation. This early detection can stop an attack before sensitive data is stolen or ransomware deployed.

Example: A user logs in from an unusual country and attempts to download large amounts of sensitive data. Behavioural monitoring flags this activity, allowing IT to respond immediately.

5. Regular Security Audits

Even the most robust systems can have blind spots. Regular audits help identify weaknesses before attackers do. Delta 365 recommends:

• Penetration testing, including AI-powered phishing scenarios

• Policy and process reviews

• Staff awareness assessments

Frequent audits provide a clear picture of vulnerabilities, ensuring your business can respond quickly and effectively to emerging threats.

6. Threat Intelligence Sharing

Cybersecurity is no longer a solo effort. Collaboration across industries and networks helps organisations stay ahead of attackers. Sharing threat intelligence allows you to:

• Identify new attack patterns

• Learn from peers’ experiences

• Strengthen collective defences against sophisticated AI threats
