The Civil Guard warns of the “yes fraud”: this is how criminals record your voice in a call
We receive calls at all hours and it is common for us to respond with a “yes”. This response can have unintended consequences in the era of new technologies, where our information is more exposed than ever. A time, where scammers and cybercriminals have more opportunities to deceive unsuspecting people.
Through vishing, a new scam technique to obtain confidential information from users. To carry out this type of scam, some prior steps are necessary, such as recording our voices saying, for example, “yes,” when we take a phone call. A simple response that can have unpleasant consequences.
By recording your response, scammers could use it to authorize banking transactions, contracts, and even falsify our identity, that is, impersonate us. In addition, it must be taken into account that before the response, any addition that could harm the reputation or integrity of any person could be included in the recording.

The scam process occurs using some resources such as an initial call, a simple conversation and the answer to some questions, the use of the recording of our voice and the detection of the victim before the scam.
The initial call: The victim of the future deception receives a phone call. The scammer poses as a representative of a sales service, customer service or a bank office, for example. The criminal may mention some personal information to increase the victim’s trust in him and lower his guard. They may mention an alleged recent transaction or the obtaining of a new product.
Ask and talk: it is also common to start a conversation with the victim to obtain basic answers that do not raise any suspicion about the scam with the aim that the answer to these questions is a simple “yes”. For example, do you agree to receive updates on our services? Are you authorizing transactions at this time? It is very common that as soon as they achieve what they are looking for, that is, the affirmative response, the scammer decides to cut off the call and end the conversation.

Use of the recording: with the recording in their possession, the fraudsters already have the raw material to perpetrate the crime. They can use it to register for a banking service with the victim’s name, among other things. You can do this by calling the financial or service entity and providing the recording acquired from the conversation as a response to confirm your identity.
Detection of the victim: The victim may realize that their identity has been used through different sources: social networks or through the contact of the service that the scammers have hired, among others. For this reason, the Civil Guard encourages reporting as soon as the victim is aware that they have been scammed, so that the State Security Forces and Bodies will be informed of this modus operandi and will be able to work accordingly.
