NOWADAYS, we could not live without the internet, a basic resource among the new generations. Remember looking for information in an encyclopedia or going to a travel agency to buy a plane ticket or make a hotel reservation? It seems like ages ago, but the truth is that the network of networks has changed the way we do many tasks and has opened the doors to new possibilities that allow us, for example, to work from anywhere or make a bank transfer from our phone in just one click.

Unfortunately, this relentless evolution is also present in the multiple threats posed by cybercriminals. We have moved on from viruses distributed on floppy disks and Morris, the first worm to infect the internet in 1988, to the emergence of Trojans, spyware and ransomware, the main protagonists of today's cybercrime scene.
