A practical approach with hands-on recipes to learn more about Scratch and its features.Scratch Cookbook is great for people who are still relatively new to programming but wish to learn more. It assumes you know the basics of computer operation. The methods of using Scratch are worked through quickly with a focus on more advanced topics, though readers can move at their own pace to learn all the techniques they need.

This book starts with the basics of ethical hacking, how to practice hacking safely and legally, and how to install and interact with Kali Linux and the Linux terminal. You will explore network hacking, where you will see how to test the security of wired and wireless networks. You’ll also learn how to crack the password for any Wi-Fi network (whether it uses WEP, WPA, or WPA2) and spy on the connected devices.Moving on, you will discover how to gain access to remote computer systems using client-side and server-side attacks. You will also get the hang of post-exploitation techniques, including remotely controlling and interacting with the systems that you compromised. Towards the end of the book, you will be able to pick up web application hacking techniques. You'll see how to discover, exploit, and prevent a number of website vulnerabilities, such as XSS and SQL injections.The attacks covered are practical techniques that work against real systems and are purely for educational purposes. At the end of each section, you will learn how to detect, prevent, and secure systems from these attacks.

本书分8章60节。第1章基础入门，本节除讲述Scratch基础知识以外，重点讲解程序开发流程，使读者养成读题一分析一解题一检查的好习惯。第2章画图专项，从绘制基本图形，到复杂图形，层层深入，循序渐进，重在归纳总结解题方法。第3章进阶算法，涵盖遍历、迭代、递归、穷举、查找、排序，都是竞赛中能用到的基本算法。第4章综合实战，对基础部分知识点进行补充与拓展。如克隆是Scratch的高级玩法，克隆体的私有变量往往容易被忽视，在学习这部分内容时，努力使自己成为一名Scratch高级玩家。第5～8章是“蓝桥杯”历年真题精讲，共30道竞赛真题，读者通过学习可做到理论结合实际，从容面对竞赛。
