  Load and execute JavaScript

When we load and execute JavaScript in a webpage, there are many points we need to care about because of its design and feature. There are two features about JavaScript execution in a browser: 1). The JavaScript codes will be executed immediately once loaded;2). When JavaScript codes are being executed, they will block the following contents (including page rendering and other resources downloading). So if there are multiple js files to be loaded, these codes will be executed sequentially. Since...

  How to choose a jQuery plug-in?

jQuery plug-in provides a good way to save time and simplify the development, programmers don't need to write each component from scratch. However, the plug-in will also be a destabilizing factor in your code library. A plug-in saves countless development time, but a poor quality plug-in will cost more than the actual time to write your own component from scratch. Luckily, usually you have many pls to choose from, but even if you have only one plug-in, you also need to know whether it's worth us...

  Python Deserialization Attack Introduction: How to Build a Python Pickle Bomb

This article introduces an old and classic unsecured Python data serialization feature (the pickle library) and demonstrates how a red team attacker can exploit it to create a malicious binary or text data file that executes remote code or commands upon deserialization. The following attack flow diagram illustrates this process: We will follow 3 steps with the program code to show how Deserialization Attacks Work:   [ Step1 ] Crafting Malicious Data: An attacker crafts a malicious payloa...
