Zimbabweans are being urged to exercise extreme caution when answering calls or sending WhatsApp voice notes, as cybercriminals are increasingly exploiting voice biometrics to commit fraud and extortion. “When you answer and say ‘hello, hello, hello’ with no response on the other side, it may not be a dropped call. While a single “hello” may not be enough to create a fake voice, Bourne warned that repeated recordings from WhatsApp voice notes, social media videos, or regular calls can provide enough material to build deepfake audio. In reality, that audio could have been lifted from a TikTok video or a WhatsApp voice note,” he warned. Limit unnecessary sharing of voice notes online.
