But not only the “yes” is risky. Greetings as common as “hello” or “hello” can also be used by automated systems designed to verify that the number is active and that the voice corresponds to a real person. By uttering these words, you indirectly confirm that your phone is in use and your voice is “valid” for future fraud attempts. When faced with an unknown call, the safest thing to do is to wait for the caller to identify themselves first or respond with phrases that allow you to detect the intention of the contact, for example, “Who am I talking to?” or “How can I help you?”.
The reason behind this interest in your voice is clear: today, digital criminals use artificial intelligence to create voice clones almost identical to the original, with just a few seconds of recording. This allows them to convincingly impersonate you and carry out fraudulent actions such as contacting your contacts to urgently ask for money, making purchases or transfers at banks that have voice recognition, or validating forged documents and contracts that look legitimate.
