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.

For the convenience of the experiment, we directly use the functions in libc.so.6 as the attack functions to be executed. This is a C program runtime in Linux, which holds a large number of available functions and contains system ("/bin/sh"). Therefore, we can use ROPgadget tool to obtain the code fragments that we can exploit, and use pwntool to exploit the vulnerabilities of vulnerable programs, thus achieving our attack purpose, that is, running system ("/bin/sh"). In order to facilitate the subsequent use of ROPgadget tool to find gadget and attack, it is necessary to copy the libc.so.6 file to the operation directory. First, use the "ldd" command to view the source directory, and then use the "cp" command to copy it to the operation directory.

Sun Tzu said: The art of war is of vital importance to the State. It is a matter of life and death, a road either to safety or to ruin. Hence it is a subject of inquiry which can on no account be neglected. Therefore, the classics are based on five (things), and the schools are based on their plans, and their feelings are asked: one is Tao, the other is heaven, the third is earth, the fourth is generals, and the fifth is law. The Tao makes the people and the people agree, so they can (to) die with it, and they can (to) live with it, instead of (fear of danger) (paradox). Heaven signifies night and day, cold and heat, times and seasons. Earth comprises distances, great and small; danger and security; open ground and narrow passes; the chances of life and death. The Commander stands for the virtues of wisdom, sincerely, benevolence, courage and strictness. Dharma, music system, official way, the main use also. All these five will be heard, those who know will win, and those who do not know will be defeated.
The original title of this book is "My Years in China, 1926-1941", and some editions are also called "15 Years in China". The book was published in 1944, four years after he went to China. The book is divided into three volumes, 36 chapters and a postscript, which has been translated into about 200,000 words in Chinese. Foreign journalists have written a lot about this period of China's history, but Matsumoto's emphasis on history, Bai Xiude's emphasis on political diplomacy, and Si Nuo's and Harrison Forman's "Report from Red China" are all different from Aban's books. Aban's book takes the form of a memoir. He has information, but it is not a record. There are a large number of historical fragments, but they are not historical works. Having personal experience, but not autobiography; There are anecdotes, but they are not anecdotes. This book is about the practice of American-style news interview, but the place where it is put into use is the ancient China that is changing in the ascendant. Liberalism's news concept and American interview operation collide with China's reality everywhere. The conventional skills of Western journalists are not enough to cope with the situation in China. He must deal with and adapt. Sometimes it is cruel, sometimes it is clever, sometimes it is compromise, but it must stick to the bottom line of truth and justice. He wrote the scenes in the interview history based on the reporter's personal experience. After reading it, I saw not only the historical situation, but also how history was projected to the media. The author's knowledge is limited, and the books he dabbles in, such as Aban's book, have yet to be discovered.
