Backdoors and Trojans

What is a Trojan

Full name of "Trojan" It is called a "Trojan horse", and its users are "hackers". It is mainly a type of "hacker" that uses deceptive methods (including bundling, using web pages, etc.) to allow users to unknowingly install it into their systems. Software, the main functions include remote control, password stealing, etc. The name of the Trojan horse points out its characteristics, that is, it is deceptive. The classification of software should not depend on its functions, but on its characteristics. Now some Trojan developers don't like to call the Trojans they develop "Trojans", but call them "remote control software". The reason is simple. "Trojan horse" has a derogatory meaning, while "remote control software" has a positive meaning. This is understandable, because after all, "Trojan horse" is also included in the expanded meaning of "remote control software". The characteristics of Trojans are also the reason why many people hate them, because it is always painful to be deceived, especially when someone emotionally deceives them; many Trojans have the function of stealing passwords, which is another reason why people hate them.

What is a backdoor

"Backdoor" is a type of software that hackers install after invading a computer in order to easily access the computer in the future. Its users are For relatively advanced hackers, the machines they invade are servers with relatively high performance, and the administrators of these computers are relatively high. In order to prevent administrators from discovering them, this requires that the "backdoor" must be very concealed. Therefore, the backdoor must be hidden. The characteristic is its concealment. The concealment of the Trojan is also very important, but since the users of the machines on which the Trojan is installed are generally low-level, the backdoor is not as important. The difference between a backdoor and a Trojan horse is that it pays more attention to concealment but is not deceptive. Therefore, it is not as harmful as a Trojan horse, and its reputation is between "remote control software" and "Trojan horse".
