Wordpress account brute-force cracking Protection I. Modify the database table prefix The default table prefix is wp _. If you have not modified the table prefix when installing the blog, you can refer to this article to modify the table prefix. After the logon test is completed, if the system prompts "you do not have sufficient permissions to access this page" after the logon is successful, the prefix is n

When I routinely checked/var/log/secure logs on the FTP backup server, I found a lot of authentication information for sshd and vsftpd failures. It is obvious that someone wants to use brute force cracking tools to steal passwords, therefore, you need to write a security script to prevent it. The script requirements are as follows: This SHELL script is placed in the crontab scheduled task and is defined eve

After replacing the "username" and "password" parameters, you can verify the password validity of other users, this causes

When asp works with the access database to have a brute-force database vulnerability, it will directly access the target website http://hi.baidu.com/foolishqiang//conn.asp '.An error is displayed, which directly exposes the database path. Hacker intruders can exploit this vulnerability to directly download the database file containing important data and then open the encrypted or plaintext password locally.

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... You should first think of the simplest way to go deeper. #include Codeforces round #253 (Div. 2) B (brute force enumeration)

Question: I will give you an infinite number of 1-10 records, from 1-M to the two ends of the balance, and place them on different balances and different weights for two consecutive times, this means that the balances placed here each time are much heavier than those placed on the opposite side. Solution: 1) brute-force search, if estimated, still cannot pass, but the actual situation is much better than th

. The number of "replies" requires that the same continuous number can be compressed into a number, such as 1233221, which can be compressed to 12321, which is the number of replies. The idea is to fill in a number for brute force enumeration. First, fill in the first number on the left in the enumeration field from large to small, and then count the number on the right in the enumeration column as it is. P

In earlier versions of Windows, there is a possibility of brute force password cracking, no matter how complicated the password is. The Win8 system uses a very special image Password Logon function to prevent viruses and Trojans. This logon method does not contain the regular characters of deep technology, viruses and Trojans cannot be cracked, which obviously greatly improves the system security defense ca

1. The registration location provides three options for users: Mobile Phone registration, email registration, and user name registration. This Vulnerability refers to the use of email registration. Why? Smart friends may have discovered that there is no verification code in the mailbox registration location (the other two methods have verification codes, which may be neglected by developers ). 2. Enter your email address, password, and nickname, and then register. After registration, you will b
