AI is making phishing attacks more convincing and harder to detect, with a 60% rise in AI-driven attacks reported recently. Staying protected requires scepticism toward unsolicited messages, multi-factor authentication, staff education and advanced security tools such as email authentication protocols.
How Phishing Has Changed
Phishing used to be simple. Attackers sent mass emails hoping someone would take the bait, usually written with poor grammar and obvious lies that most people could spot easily. That’s no longer the case. Attackers now use AI to craft convincing messages and target specific individuals, making phishing far more effective than it used to be.
Realistic, Personalised Messages
AI can analyse huge amounts of data on how people write and speak, then use this to create messages that sound like they come from a real person and mimic the tone of legitimate communications. This makes them much harder to spot.
AI also pulls information from social media and other sources to build personalised messages that reference details about your life, such as your job, hobbies or recent activities. This personal touch makes people far more likely to believe a message is genuine.
Spear Phishing and Automation
Spear phishing targets specific individuals or organisations and AI makes it even more dangerous by helping attackers research their targets in depth. The result is highly tailored messages that are difficult to distinguish from legitimate ones.
AI also automates much of the process. It can send thousands of phishing messages at once and adapt based on how targets respond. If someone clicks a link but doesn’t enter information, AI can follow up automatically, increasing the odds of eventual success.
Deepfakes Add a New Layer
Deepfake technology uses AI to create realistic fake video and audio, and attackers are now using it in phishing attacks. A deepfake video of a CEO asking for sensitive information adds a convincing new layer of deception that traditional phishing never had.
The Real Impact
AI-enhanced phishing leads to higher success rates, since more people fall for sophisticated attacks, resulting in more data breaches, financial losses and identity theft. Traditional detection methods also struggle against these attacks: spam filters may miss them and employees may not recognise them as threats, which only makes success easier for attackers. When these attacks do succeed, the damage tends to be more severe, from significant data breaches to disrupted operations.
How to Protect Yourself
Staying sceptical is your first line of defence. Treat unsolicited messages with caution even if they appear to come from a trusted source, verify the sender’s identity and avoid clicking links or downloading attachments from unknown sources.
- Watch for red flags such as generic greetings, urgent language or requests for sensitive information, and be wary of anything that seems too good to be true.
- Multi-factor authentication adds a critical extra layer of security. Even if an attacker gets hold of your password they’ll still need a second form of verification, making it much harder to access your accounts.
- Education matters too. Learning about phishing tactics and staying informed on emerging threats helps you and your team recognise and avoid attacks. Share what you learn with others so the whole organisation benefits.
- Never provide sensitive information over email. If you receive a request, verify it through a separate channel, such as calling the person directly using a known number.
- Investing in advanced security tools, such as anti-phishing software and email filters, helps detect and block phishing attempts before they reach your inbox. Keep this software up to date to stay ahead of new tactics.
- Reporting phishing attempts to your IT team or email provider helps strengthen your organisation’s defences and protects others from falling for the same attack.
- Enabling email authentication protocols like SPF, DKIM and DMARC helps protect your domain against spoofing, adding another layer of protection to your email communications.
Finally, regular security audits help identify vulnerabilities in your systems before attackers do, giving you the chance to address weaknesses proactively.
