The Civil Guard and the National Cybersecurity Institute warn of this new scam, which does not require any type of “hacking” of the mobile phone
The Bizum app is already part of the lives of many Spaniards as the easiest and most comfortable way to make small money transfers between friends or acquaintances. Also to make small purchases between individuals or companies in a comfortable way, through the banking app and without the need to enter personal or card data.
But once Bizum becomes a common payment method, it can also become a threat to the user. And that Bizum maintains that it has no security flaws and that most threats are criminals who trick their targets into obtaining their bank details. This is the case of “reverse Bizum”, the new scam against which the Civil Guard and the National Institute of Cybersecurity (Incibe) have warned. A very effective scam that can make users lose money in the easiest way, without the need to “hack” the cell phone or use malicious programs. Just taking advantage of a lack of customer attention.
Reverse Bizum is nothing more than the technique by which criminals obtain money from a user when in reality the customer believes they are receiving payment. Hence the name, since the user believes he is accepting a payment from Bizum, when in fact he is agreeing to make a payment.
Incibe has detected a new fraud strategy conducted through the Bizum app that targets sellers of items requiring payment through this means in which cybercriminals pose as buyers.
The reverse bizum scam is very simple and you just have to be careful what you receive to avoid it. Instead of sending you money through Bizum, they give you the option to request, i.e. they ask you for money. Then a message comes up that says if you want to send money to that person, it’s as simple as rejecting it, but if we’re in a hurry or read on the side, the scam is served.
This new attempt at fraud is mainly carried out through buying and selling platforms, such as Milanuncios, Vinted or Wallapop, where any user can put an item up for sale.
The cybercriminals show their interest in buying the item, and once they gain the seller’s trust, they indicate that they want to make the payment through Bizum. Taking advantage of the seller’s ignorance of how this application works, he sends a payment request instead of sending the money for the product.
The Civil Guard warned of a case in Pamplona in which they took 9,000 euros. He was selling a bicycle through a peer-to-peer buying and selling platform, the price was 100 euros and they continually demanded this amount until the victim realized that his account balance was dropping. The Civil Guard assures that, even if they scam a small sum, you must always report it as soon as possible to avoid stopping this type of scam.
