WHEN HACKERS WEAPONISE ARTIFICIAL INTELLIGENCE, YOUR DIGITAL DEFENCES MUST EVOLVE

Five essential cybersecurity measures to counter AI-powered scams, sophisticated phishing attacks and increasingly convincing digital deception

THE VANGUARD REPORT | TECHNOLOGY & CYBERSECURITY | 23 OCTOBER 2026

Artificial intelligence is transforming the digital world, creating new opportunities for innovation while also giving cybercriminals increasingly sophisticated tools to deceive individuals and compromise digital systems. From highly personalised phishing messages to convincing impersonations of trusted people and organisations, AI-powered attacks are making it harder to distinguish genuine communication from malicious attempts to steal personal information, financial credentials and account access.

Traditional cybersecurity practices remain important, but users can no longer rely solely on spotting spelling mistakes, suspicious formatting or obviously fraudulent messages. AI tools can help attackers produce fluent language, imitate communication styles and automate the creation of deceptive content at scale. Protecting oneself therefore requires a combination of technical safeguards, careful verification and responsible digital behaviour.

Here are five essential measures that can help individuals strengthen their defences against AI-powered cyber threats.

1. QUESTION UNEXPECTED MESSAGES, EVEN WHEN THEY LOOK AUTHENTIC

One of the most significant risks associated with AI-powered cybercrime is the increasing sophistication of phishing attacks. Cybercriminals can use artificial intelligence to generate convincing emails, text messages and social media communications that imitate banks, online platforms, employers, government agencies or other trusted organisations.

Such messages may claim that an account has been compromised, a payment has failed or urgent action is required to prevent a service from being suspended. Their objective is often to persuade recipients to reveal passwords, disclose one-time passwords (OTPs), provide banking details or open malicious links.

Users should avoid clicking links or opening attachments simply because a message appears professionally written or comes from a familiar-looking account. Instead, they should independently visit the organisation's official website or use its verified application to check whether the request is genuine. Unexpected requests for confidential information should always be treated cautiously.

The fundamental principle is simple: verify the request independently before taking action.

2. VERIFY IDENTITIES BEFORE TRUSTING VOICE OR VIDEO CALLS

Artificial intelligence has made it easier to create convincing audio and video imitations of real people. Criminals may exploit these technologies to impersonate relatives, colleagues, business executives or other trusted individuals, sometimes requesting urgent financial transfers or confidential information.

A familiar voice is no longer sufficient proof of identity, particularly when a call involves an unusual request, an emergency or pressure to act immediately. Deepfake technology can make fraudulent communications appear authentic, exploiting the trust people naturally place in familiar faces and voices.

If someone claiming to be a relative or colleague requests money or sensitive information unexpectedly, contact that person through a separate, previously established communication channel. Families and organisations can also agree on a private verification phrase or procedure for particularly sensitive requests.

Avoid making payments solely on the basis of an urgent voice message or video call. Taking a moment to confirm the request independently can prevent costly mistakes.

3. STRENGTHEN PASSWORDS AND ENABLE MULTI-FACTOR AUTHENTICATION

Weak, reused or easily guessed passwords can expose multiple accounts if one service suffers a data breach. AI-assisted tools may also help attackers automate attempts to guess passwords or exploit stolen credentials.

Users should create long, unique passwords for important accounts, especially email, banking, social media and cloud services. A reputable password manager can help generate and securely store different passwords without requiring users to memorise every combination.

Multi-factor authentication (MFA) provides an additional layer of protection by requiring another form of verification beyond the password. Where available, passkeys or authentication applications are generally preferable to relying exclusively on SMS-based verification, particularly for high-value accounts.

Users should also protect their primary email account carefully because access to it may allow criminals to reset passwords for other services. Recovery options should be kept current, and unexpected login notifications should be investigated promptly.

No single security measure guarantees complete protection, but combining unique passwords with strong authentication significantly improves account security.

4. KEEP DEVICES, SOFTWARE AND SECURITY TOOLS UPDATED

Cybercriminals frequently exploit known software vulnerabilities to gain unauthorised access to computers, smartphones and online systems. AI may help attackers identify potential weaknesses or accelerate parts of their operations, making timely security maintenance increasingly important.

Operating systems, web browsers, mobile applications and security software should be updated regularly. Automatic updates can help ensure that important security fixes are installed without unnecessary delays.

Users should download applications only from trusted sources and avoid installing unfamiliar software promoted through unsolicited messages, advertisements or suspicious websites. Unnecessary applications and browser extensions should be removed, while device security features such as screen locks and built-in protection should remain enabled.

Public Wi-Fi networks also require caution when accessing sensitive accounts. Users should verify the network they are connecting to and avoid entering confidential information on suspicious websites. When available, secure connections and appropriate organisational VPN services can provide additional protection.

Keeping software current reduces exposure to known vulnerabilities and forms an essential part of a broader cybersecurity strategy.

5. PROTECT PERSONAL INFORMATION AND THINK BEFORE SHARING

AI-powered attacks become more convincing when criminals have access to personal information about their targets. Public social media posts, professional profiles, photographs, travel updates and details about family relationships can help attackers construct believable stories or impersonate trusted individuals.

Users should review their privacy settings and limit the personal information they make publicly available. Sensitive documents, financial information, identity details and private photographs should not be uploaded to unfamiliar websites or untrusted AI applications without understanding how the information may be stored and used.

Before sharing information or authorising a transaction, consider whether the request is appropriate, whether the recipient's identity has been verified and whether the information is genuinely necessary.

Organisations should also educate employees about AI-assisted fraud, establish clear payment-verification procedures and ensure that confidential information is handled securely. Financial transfers, changes to payment instructions and requests for sensitive business data should require independent confirmation through approved channels.

Digital literacy is an important defence because technology alone cannot eliminate every form of deception. Recognising manipulation, checking claims and resisting artificial urgency can help users avoid becoming victims of increasingly sophisticated attacks.

CYBERSECURITY IN THE AGE OF AI: VIGILANCE IS ESSENTIAL

Artificial intelligence is changing the methods available to cybercriminals, but many successful attacks continue to exploit familiar weaknesses: misplaced trust, reused passwords, inadequate verification and the disclosure of sensitive information.

Individuals cannot prevent every cyberattack, and even experienced users may encounter highly convincing deception. However, maintaining updated devices, using strong authentication, independently verifying suspicious communications and limiting unnecessary data sharing can reduce exposure to common threats.

The objective is not to fear artificial intelligence but to understand how it can be misused and respond with informed caution. In an increasingly connected society, cybersecurity is a shared responsibility involving individuals, technology providers, financial institutions and public authorities.

The strongest digital defence combines reliable security tools with a habit of questioning the unexpected. In the age of AI-powered deception, verify first, protect your credentials and never let urgency replace judgement.
