That’s the warning from cybersecurity expert Lucas Molefe, who says WhatsApp users in South Africa are staring down a fast-growing wave of impersonation scams. And that’s what scammers exploit: urgency and trust.”And trust is what makes people drop their guard. “If it’s taken via SIM swap, they’ve actually taken control of your number, so that’s a bit difficult,” Molefe said. And above all, never, ever hand over an OTP on WhatsApp, even if the message looks like it’s coming from someone you know. Because once they’ve got your number, they’ve got the keys to your whole digital kingdom.
