Factory Pattern: Factory Pattern is a frequently used pattern. Classes implemented according to Factory Pattern can generate instances of one of a group of classes according to the provided data. Usually, this group of classes has a common abstract parent class and implements the same methods, but these methods perform different operations for different data. First of all, we need to define a base class. Subclasses of this class implement methods in the base class through different methods. Then you need to define a factory class that can generate different subclass instances according to conditions. After getting an instance of a subclass, developers can call methods in the base class regardless of which subclass instance is returned.

Super factory viruses can exploit software vulnerabilities in the form of "zero-day vulnerabilities" (zero-day vulnerabilities are also called zero-time difference attacks, which refer to security vulnerabilities that are maliciously exploited immediately after being discovered). The virus will quietly infect a system, and the user does not need to do anything specially to make the virus worm take effect, such as accidentally downloading a malicious file. Moreover, it is not only spreading in Iran's nuclear system, this worm virus can spread through Windows systems all over the world. To some extent, this is because, in order to enter Iran's system, attackers infected computers outside Iran's network system with viruses (but these computers are believed to be connected to them), so that these computers can act as "carriers" of viruses.
