Figure 1 is an example of a JOP attack. In this example, the attacker's aim is to execute a system call "int 0x80" to open a new command line window. To do this, an attacker needs to modify the contents of the eax register to "0x0000000b" and the ebx register to the string "/bin/sh" before "int 0x80" is called, and the ecx and edx registers must point to the value "0x00000000". Suppose the value "0x0000000" and the string "/bin/sh" can be found in memory when the program is running. An attacker needs to construct the value "0x0000000b" himself. However, for the value "0x0000000b", when an attacker saves data to the stack through a buffer overflow, the "0x00" byte will trigger the system to terminate the read operation. This example specifically describes how the attacker uses the existing code snippet in the program to modify the value of val pushed into the stack by the attacker step by step from "0xffffff0b" to the value required by the system call "0x0000000b", thus implementing JOP attack. The following are the detailed steps of the process.

Know the principle + can change the model details man: read the paper, read the paper, read the paper! Read source code read source code read source code! The source code reading here is not limited to reading the source code of one framework. You can look at other excellent frameworks. For the implementation mechanism of the same layer and the same function, you can think more, summarize more and write more. After a long time, there will definitely be gains. The purpose of reading the paper is to directly obtain the original author's thoughts, avoiding obtaining second-hand thoughts from blog interpretation of the paper. After all, everyone's understanding is different, and it is not necessarily right. Read it first, then look at other understandings, and discuss with Daniel more, thus broadening the thinking.
Industrial software such as MES (Manufacturing Execution System), APS (Advanced Production Scheduling), PLM (Product Life Cycle Management), ERP (Enterprise Resource Planning) and Quality Management are widely used to realize visualization and transparency of the production site. When a new factory is built, the digital factory simulation software can be used to simulate the layout of equipment and production lines, factory logistics, ergonomics, etc. to ensure the reasonable structure of the factory. In the process of promoting digital transformation, it is necessary to ensure the data security of the factory and the security of equipment and automation systems. When defective products are detected through professional testing equipment, not only should they be automatically separated from qualified products, but also the causes of quality problems can be analyzed through SPC (Statistical Process Control) and other software.
The 10,000-hour law is helpful, but it still requires perseverance and many cycles of practice. (The 10000 hour rule helps. But to be achived, it needs persistence and passing through a lot of cycles.)
