Where mobile money has become a financial lifeline for millions, trust is currency. That trust was recently tested following a viral claim of fraud involving an MTN Ghana mobile money customer and the subsequent responses from MTN and the Data Protection Commission (DPC) of Ghana.
The DPC has issued a statement noting that investigations are ongoing. While the facts are still unfolding, this situation offers a valuable opportunity to objectively explore how such incidents can occur and how individuals, organizations, and regulators can view this.
Understanding the Possible Attack Vectors
Regardless of whether the root cause lies in infrastructure, policy gaps, or human error, cybersecurity professionals aretrained to analyze potential pathways for compromise. Here are a few common ones:
🔹Phishing & Social Engineering
Phishing remains one of the most successful and low-cost ways to steal user credentials. Attackers craft fake messages that imitate trusted sources (banks, telcos, or payment platforms), often persuading victims to click malicious links or share OTPs and PINs. Spyware or remote access tools may also be deployed via such links to harvest sensitive data.
🔹 SIM Swap or Account Takeover Attacks
SIM swap fraud is another growing concern. In this scenario, attackers gain control of a victim’s phone number, either through social engineering at mobile service outlets or via insiders. This allows them to intercept SMS-based authentication messages, such as OTPs or password reset codes.
🔹Endpoint Compromise
In some cases, the device itself is the weak point. Installing apps from unofficial sources can lead to infection with spyware or key loggers. These tools can silently capture user input, monitor transactions, or forward OTPs without the user’s knowledge.
🔹 Poor Digital Hygiene & Environmental Exposure
Cybersecurity is not only about software — how users interact with systems matters too. Entering a mobile money PIN under visible CCTV surveillance, reusing the same password across apps, or writing login credentials on paper all introduce avoidable risk.
User Education: The First Line of Defense
No security system is perfect, but many compromises are preventable through simple, consistent digital hygiene practices. These should be part of basic digital literacy in the mobile economy:
- Avoid clicking on unverified links — Phishing links often appear legitimate but lead to credential theft.
- Don’t install unofficial apps — Stick to verified app stores and avoid APKs or clones.
- Shield your PIN entry — Be cautious of who or what might be watching, especially in public places.
- Change your PIN regularly (every 3–6 months) — This limits the lifespan of any leaked credentials.
- Avoid writing your full PIN or password down — And never reuse credentials across platforms.
- Use two-factor authentication (2FA) wherever available — It adds a critical layer of protection.
While individuals bear responsibility for their own vigilance, institutions must also prioritize user-friendly security that doesn’t rely solely on customers to make perfect decisions under pressure.
A Balanced View on Responsibility
It’s essential not to rush to judgment. Cyber incidents often involve both technical complexity and human factors. Even when infrastructure remains intact, attackers are constantly evolving tactics to exploit the weakest link which is often the user.
Regulators like the DPC play a key role in setting expectations for accountability and response. Their readiness to enforce provisions under data protection law reinforces the seriousness with which these incidents are treated, whether the fault lies with the service provider, a third party, or user behavior.
As Africa’s digital infrastructure grows, so too will the complexity of threats. It’s no longer a question of if fraud attempts will occur—but how ready we are to detect, respond, and recover.
The lesson here is clear: security is a shared responsibility.
