The Dark Side of AI: How Scammers, Hackers, and Trolls Are Using It Against You

Pepper (Artificial Intelligence)

Introduction

Artificial Intelligence (AI) has the power to transform our lives for the better — from medical breakthroughs to instant language translation. But as the technology becomes more accessible, bad actors are finding ways to use it for scams, cybercrime, and misinformation.

In South Africa, where cybercrime is on the rise, AI has already made scams more convincing and harder to detect. This post breaks down how criminals are weaponising AI and what you can do to stay ahead.

How AI Is Powering Modern Scams

1. Deepfake Impersonations

AI can create realistic audio and video of people saying or doing things they never actually did. Criminals have used this technology to impersonate CEOs, politicians, and even family members.

Local Example: In 2024, a Johannesburg business nearly lost millions when fraudsters used an AI-generated voice to mimic the company’s CEO during a phone call.

2. Phishing Emails That Learn

AI can scan your social media and public records to craft personalised phishing messages that look like they come from someone you know.

Instead of the old, clumsy “Nigerian prince” scams, you now get an email that references your recent purchases, workplace, or even local slang.

3. Fake News and Disinformation

AI can mass-produce convincing news articles, social media posts, and fake images in minutes. These are often used to sway public opinion or cause panic.

Example: Fake crime alerts and protest announcements have been spread via WhatsApp in South Africa, leading to real-world chaos.

4. Automated Hacking

AI tools can help hackers find vulnerabilities in websites and networks faster than ever. This makes cyberattacks cheaper and more accessible for criminals.

5. AI Chatbots for Fraud

Some criminals deploy AI-powered chatbots to impersonate customer support agents. They can keep victims engaged long enough to steal login details or banking information.

Why This Is a Bigger Threat in South Africa

• High mobile usage means more targets for SMS and WhatsApp-based scams

• Limited digital literacy makes it easier for scammers to trick victims

• Weaker cybercrime laws and slower enforcement compared to some countries

  
  

How to Protect Yourself

1. Verify Before You Trust

   If a message, call, or video seems suspicious, verify it using a known, official channel.

2. Enable Multi-Factor Authentication

   This adds an extra layer of security even if your password is stolen.

3. Stay Updated on AI Trends

   The more you understand how AI works, the easier it is to spot suspicious content.

4. Use Reverse Image and Video Searches

   Tools like Google Images or InVID can help confirm whether a photo or video is real.

5. Report Suspicious Activity

   Forward phishing SMS to 7726 or report scams to the South African Police Service Cybercrime Unit.

   
   

Final Thoughts

AI is not inherently bad — but in the wrong hands, it becomes a powerful weapon for deception. Staying informed and cautious is your best defence. Remember, if something feels “off,” it probably is.
