Smurf is not a Trojan as such, but a group of viruses with the following characteristics:
- They spread through any of the usual means of transmission used by other viruses.
- Their most dangerous effect involves launching DoS attacks, that is, to gain repeated access to certain computers (generally servers) in order to cause them to block.
- Infection is carried out when the file that contains the Trojan is run. This file, with a variable name, carries out the infection in different ways and tries to pass unnoticed. Sometimes, it is included inside other viruses or worms.
The actions carried out by Smurf are more dangerous in the computers it attacks remotely than in the infected computer.
These types of programs usually use the communication ports that are not protected in the attacked computer.
As it is not really a virus, Smurf does not display any messages or warnings that indicate that it has infected a computer.
