Phone burla schemes continue to gain sophistication, but there are new methods that are distinguished precisely by simplicity, because recently a technique has raised concerns between cybersecurity experts: voice cloning and words based on brief response captured during seemingly harmless calls.
The goal is clear from the beginning: capture three keywords said by the victim, capable of being manipulated by artificial intelligence systems. These expressions, when isolated and processed, can be used to validate financial operations or enter into contracts in the name of the targeted person, even without their actual consent.
What you should never say in a call
According to the Electronical Economic Economic Journal, the words most sought after by the burns are “yes”, “ok” and “accepted.” When captured by phone, these answers become raw material for tools that simulate the user’s voice with a worrying level of realism.
These imitations allow, for example, to positively respond to automatic recordings, authorize transfers or open accounts in the name of the victim. Everything without any intention to do so.
How the scheme starts
The trick can start with a silent call or with someone who presents itself as a representative of a well-known company. It can be a telecommunications operator, a bank or a delivery company. The idea is to generate confidence and lead the interlocutor to say one of these three words without suspecting.
Some approaches include closed response questions, such as “are you listening to me well?” So that the victim automatically says “yes”.
Reinforce surveillance
Experts recommend that, in unreserved calls, never share personal data, passwords or bank information. Whenever there are questions about the identity of those who are calling by phone, the call without words should be finished and directly contact the entity concerned.
Explains what these fraud can result in identity usurpation, fraudulent banking and even celebration of false contracts. And most worrying is that everything can start with a simple word said on the phone.
Consumer protection authorities and entities continue to raise awareness of the growth of this type of circumvents, noting that in this type of crime, prevention remains the best defense.
