One problem with the factory method pattern is that the creation of the class depends on the factory class, that is to say, if you want to expand the program, you must modify the factory class, which violates the closure principle. Therefore, from the design point of view, there are certain problems, how to solve them? We use the abstract factory mode to create multiple factory classes, so that once new functions need to be added, we can directly add new factory classes without modifying the previous code. Because the abstract factory is not very easy to understand, let's look at the diagram first, and then it is easier to understand with the code.

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.
