Pilar Clavería: For a cybersecurity bank: Offer? No, thanks



If when you are calmly resting or busily doing something, you receive a phone call saying that it is one of your supply companies to inform that, as a customer, you have a very interesting offer, be suspicious. If to give credibility to the call, they begin to quote data they have about you, be suspicious. If to access the offer, you only have to accept it and give them some information that they will send to your mobile to confirm it, be suspicious.

If the real supply company were to apply a discount, it would do so without further ado and inform you of it, but you probably wouldn’t have to do any confirmation. If they have certain data, it is because they have probably collected it in an irregular way. If you share the data that reaches your phone, it is probably you are giving them the security codes to access your electronic banking, at whose door they are waiting to enter with very bad intentions.

If you receive such a call, make it clear that you cannot attend them and that you will call the company in question later to make the offer. Of course, if you want to check the veracity of the call, find the official contact information on the company’s periodic invoices and go to them, but never use a number that they provide to return the call. If you answer the call out of curiosity or because it is credible, never give consent. And never, never! share with third parties security keys that the bank sends you; They are just that, security keys, it would be like handing over the access keys to the friends of others who lurk at the door with insane intentions.

And if at this point you wonder how it is possible that they have so much information and so precise there are several possible answers: they have been able to access that personal data in an illegitimate way, through security breaches in companies that legitimately guarded them, that are trafficked in the market black. Or think that it may simply be information that you have shared online, either on social networks or by filling in forms to sign up for a website or service in response to tempting offers, in which personal data, telephone data, addresses are required. , etc…

If you find out after all this has happened, contact your bank, who will advise you on how to proceed. And remember, banks, as in branches have security measures to prevent unwanted access, they also safeguard customer funds and data in the virtual world. They are prepared to contain illegal incursions, but if the bad guy comes to the door with the keys to enter because we have given them incautiously, it will be difficult to stop his access. Be cautious and do not do on the internet what you would not do in the physical environment.
