The name Trojan comes from the ancient Greek legend, which refers to controlling another computer through a specific program (Trojan program). Trojans usually have two executable programs: one is the client, that is, the control end, and the other is the server, that is, the controlled end. As the name implies, it is a network virus that hides in disguise and comes out to harm people when the time is right.

Infection mode: send it by email attachment and bundle it in other programs.

Virus features: It can modify the registry, reside in memory, install backdoor programs in the system, and start and load the attached Trojan horse.

Destruction of Trojan virus: Trojan virus attacks need to run the client program on the user's machine. Once it attacks, you can set up a back door to send the user's privacy to the address specified by the Trojan program on a regular basis, and generally there is a built-in port to enter the user's computer, and you can arbitrarily control this computer to perform illegal operations such as file deletion, copy and password modification.

Phishing is an attack method, which sends a large number of deceptive spam messages claiming to come from banks or other well-known institutions, with the intention of luring the recipients to provide sensitive information (such as user name, password, account ID, ATM PIN code or credit card details). The most typical phishing attack is to lure the recipient to a phishing website that is very similar to the website of the target organization through careful design, and obtain the personal sensitive information input by the recipient on the website. Usually, this attack process will not alert the victims. This personal information is very attractive to hackers, because it enables them to impersonate the victims to conduct fraudulent financial transactions, thus gaining economic benefits. Victims often suffer heavy economic losses, or all personal information is stolen and used for criminal purposes.
