AI-Powered Cybercrime Is Raising the Risk for South African SMEs

Artificial intelligence is not only helping businesses automate work. It is also helping cybercriminals create convincing scams, analyse targets and launch attacks more efficiently.

INTERPOL’s 2026 African Cyberthreat Assessment reports that artificial intelligence was involved in 55% of reported cybercrime across Africa. The assessment also identifies South Africa as a particularly significant ransomware target, accounting for 92% of detections in the African dataset cited by the report.

These figures do not mean that 92% of every ransomware attack in Africa occurred in South Africa. They come from a specific threat-detection dataset. They do, however, reinforce what local businesses are already experiencing: South Africa is an attractive and active target.

How criminals use AI

Traditional phishing emails were often easy to identify because of poor grammar, strange wording or an obviously incorrect company logo.

Generative AI can now produce polished emails that imitate the tone of a supplier, manager or colleague. Criminals can use information from company websites, social media profiles and leaked databases to create messages that feel relevant to the recipient.

AI may help attackers:

• Write convincing phishing messages
• Translate scams into natural local language
• Generate or modify malicious code
• Analyse stolen information more quickly
• Impersonate executives or suppliers
• Automate reconnaissance against exposed systems
• Produce fake voices, documents or payment instructions

A small criminal operation can consequently target more businesses without employing a large technical team.

Why SMEs are attractive targets

Many business owners assume that criminals are interested only in banks, government departments and major corporations. In reality, SMEs frequently combine valuable information with weaker protection.

A smaller business may hold customer identity documents, banking information, contracts, payroll records and access to larger customers or suppliers. At the same time, it may rely on a single administrator, basic antivirus and backups that have never been tested.

Automated attacks do not need to know the company personally. They scan for weak passwords, exposed remote access, outdated websites, unpatched computers and compromised Microsoft 365 accounts.

MFA is essential—but it is not the whole solution

Multifactor authentication remains one of the most important protections a business can deploy. However, modern attackers also use fake login approval requests, stolen browser sessions, malicious email rules and social engineering.

Effective SME protection should therefore include several layers:

• MFA on all business accounts
• Separate, protected administrator accounts
• Endpoint security on every computer
• Prompt Windows and application patching
• Email filtering and domain protection
• Independent Microsoft 365 and server backups
• Regular restore testing
• Monitoring for suspicious logins and forwarding rules
• Staff training using current scam examples

No individual security product can compensate for missing backups, excessive permissions or an administrator account shared by several people.

What business owners should do now

Start with a short security review rather than buying random products. Identify where company data resides, who has administrative access, whether departed employees still have access and whether the business could recover from a compromised account.

Staff should also be given a clear verification rule: unexpected requests involving payments, bank-detail changes, passwords or confidential documents must be confirmed through a second communication channel.

AI is increasing the speed and quality of cybercrime, but businesses are not powerless. Strong identity controls, managed protection, tested recovery and alert employees still stop many attacks.
