As we all know, NC is a powerful and flexible hacker tool. It can be used to do many things, such as telnet client ports. For example, it can rebound back to Shell during intrusion, such as scanning ...... But have you ever thought about creating a service-level backdoor? Many cainiao like me do not know programming yet, and the popular webshells written by others are often killed. Let's create a webshell together with me, no programming knowledge is required. First, please refer to the inaccess

previous article every day or at least two days. The result is that the current project is coming to an end and the code is changed every day, the changed eyes cannot be opened, and the busy brain won't be able to change. I feel a little confused, not me. No matter how long I have time, I have to keep writing it, why do we need to write this foundation? On the one hand, we need to learn about new things with a warm understanding, and on the other hand, we need to improve our writing skills. ple

Test with a knife and fly with a stupid birdPreface General classes and methods can only use specific types: either basic data type or custom class. If you want to write code that can be applied to multiple types of code, such rigid restrictions will be very restrictive to the code. -- Think in Java What are the benefits of generic programming? It is hard to imagine that the requirement "can be applied to multiple types of code" exists at the beginn

Python scientific computing Swiss Army Knife-Anaconda installation and configuration, pythonanacondaIntroduce Python is a powerful programming language that provides many scientific computing modules, including numpy, scipy, and matplotlib. To use Python for scientific computing, you need to install the required modules one by one. These modules may depend on other software packages or libraries, so installation and use are relatively troublesome. Fo
