Today’s money mission
Imagine this situation: You check your bank balance on the free Wi-Fi at a your city café. An attacker on the same network captures your session.
What you need to know
Risk categorisation by consequence: high-risk activities are those where compromise produces financial or identity damage. Watching YouTube on café Wi-Fi — low consequence if traffic is captured. Entering your investment account password — high consequence. The rule: any activity requiring authentication credentials on a financial platform should use mobile data or a trusted VPN. Convenience of free Wi-Fi is not worth the risk for financial activities.
Real-life example
Real-life money moment: You need to urgently transfer money while at an airport with only public Wi-Fi available. Design the safest possible approach. — Safe transfer option hierarchy: mobile data (cellular network, not Wi-Fi — eliminates the attack vector entirely). VPN on public Wi-Fi (encrypts traffic so interception is useless). USSD banking (*737#, *966#, *322# etc.) — runs on telecom network, completely separate from Wi-Fi, unaffected by network attacks. These three options cover virtually all scenarios. The key insight: USSD is a powerful backup that most Nigerians have access to.
