Silent call scams demand public vigilance

I REFER to the report “Silence is golden in new call scam” (The Star, Dec 4) on the latest tactic used by scammers – using silent calls to harvest voice data that would then be cloned with artificial intelligence tools and used to impersonate the victims.

The method is deceptively simple. A call comes in from an unknown number. When the recipient answers, the line remains silent.
