Here in Brazil, a transfer tool called PIX was recently developed. The aim was to facilitate the movement of money into individuals' accounts through their own banking applications, without the need for processing or bank fees (in short).
Guess if the number of cell phone clonings hasn't exploded?? The bastards send SMS with links that clone messaging apps and ask to borrow money as if they were you, to resolve an emergency but which they would return within a few hours.
In other words, they no longer need to directly defraud your bank account or payment methods, just borrow money from your mother, brother, friend. What some people are doing, for example, is saving the name without identification in their contact lists... not saving "father", or "love", or "my sweetheart".. and always deleting the message history to that in case of cloning, the scoundrel doesn't know who is who.
So, yes, they are "working hard", we have to be increasingly vigilant.
