Trojan
It is a malware that tricks the user looking like a seemingly harmless program (emails, pictures, music ...) but when run creates a backdoor that allows remote access to the attacker. It is composed by two files (client that sends orders and server who executes them).

Logic Bomb
It is a part of code in a program that remains hidden until a predetermined moment (a date, a command, an event) is triggered.

It is a technique of obtaining information, manipulating the innocent user. With the increase of e-mail, websites and social networks, it is increasingly common to find deceptions to obtain confidential data such as: passwords, card numbers, etc. Some examples of this type of deception are: phishing, chain emails, renewal of the access to a website, or even by a phone call.
