Cybercriminals are becoming more smarter with the help of AI

Cybercrime is rapidly evolving, and the methods criminals use are becoming more sophisticated.
Mike Bolhuis, an expert in serious crimes including cybercrime, highlights that social engineering – where criminals pose as trusted figures to manipulate victims – is one of the most common tactics. Older individuals, in particular, are at risk due to their limited knowledge of technology.
But it’s not just fraudsters using phone calls or emails anymore – emerging technologies like artificial intelligence (AI) and machine learning are now driving the evolution of cybercrime.
Mike Bolhuis pointed out that social engineering is one of the most effective tactics criminals use today.
In this form of cybercrime, fraudsters impersonate legitimate organisations or trusted figures to trick victims into sharing personal or financial information.
Older people, who may not be as familiar with modern technology, are particularly vulnerable to these schemes.
“In the past, criminals relied on pen and paper. Now, with just a few clicks, they can gather sensitive details,” Bolhuis said.
"What’s even more concerning is the statistics: 90% of data breaches occur when criminals manipulate victims into disclosing personal information over phone calls, emails, or even in person."
Bolhuis stressed that while it’s impossible to eliminate the risk entirely, awareness and training are key to reducing vulnerability.
"Even with training, mistakes happen, but knowledge can drastically reduce the likelihood of falling victim," he explained.
"Awareness of the signs of social engineering attacks can make a huge difference."
As technology evolves, so too does the sophistication of cybercrime. Estevao Kovata, founder and CEO of Transact Connect Consulting, warns that today’s cybercriminals are not only opportunistic hackers but often highly skilled individuals with advanced technical knowledge.
“Cybercriminals are increasingly using AI and machine learning to exploit vulnerabilities in digital platforms such as banking apps, e-commerce sites, and more,” said Kovata.

Ransomware attacks are a growing threat, with criminals encrypting a victim’s data and demanding a ransom, often in cryptocurrency, to release it.
Kovata stressed the importance of strong passwords and multi-factor authentication to protect your accounts. He also advised people to be mindful of what they share online, as seemingly small details can be used against them.
“Cybercriminals track your transactions, learn your habits, and stay one step ahead,” Kovata explained.
"With criminals using AI to automate and personalise attacks, it’s crucial to stay vigilant and take proactive steps to secure your digital life."
Willem Els, Senior Training Coordinator at the Institute for Security Studies, noted that cybercrime is no longer just about stealing money.
"Criminals are increasingly using digital tools for extortion and large-scale hacking. Sensitive company information is stolen, sometimes to be sold or held for ransom.
“Some cybercriminals are stealing huge amounts of corporate data and extorting companies for large sums of money,” Els said.
The introduction of the Cybercrimes Act in 2020 has helped address this growing threat, but Els stressed the need for better collaboration between the public and private sectors to combat cybercrime effectively.
“Cybercrime crosses borders, so international cooperation is crucial for effective prosecution,” he added.
Els also warned that while emerging technologies like blockchain and AI offer new opportunities for secure data storage and breach detection, criminals are exploiting these same technologies for illegal activities, such as terror funding.
The threat of cybercrime is more present than ever, but there are steps you can take to protect yourself.
Bolhuis, Kovata, and Els all agreed that the best defence is a combination of awareness, technology, and vigilance.
Bolhuis emphasised the importance of training and awareness, especially for vulnerable groups like the elderly, who are often targeted by social engineering.
Kovata advised using strong, unique passwords, enabling multi-factor authentication on your accounts, and being cautious about what you share online. “Your digital footprint is permanent, so be careful who you trust with your information,” he warns.
Els called for better resourcing of law enforcement and greater collaboration between businesses and governments to tackle the global nature of cybercrime. With criminals working across borders, stronger international cooperation is essential to combat cyber threats.
