The topic of security has acquired more and more importance over the years, effectively becoming a central issue for those who manage web projects. The most effective defense, in these cases, is prevention . It is not always possible to know in advance how attackers act, but we can consider the most common attacks to understand how to protect your WordPress website from possible intrusions. Content index: Brute Force attack Brute force attack software SQL Injection Cross Site Scripting How to protect your site from Cross Site Scripting? Brute Force attack Brute force is one of the oldest and most widespread attacks, although it is usually the last attempt to damage or steal data as it is time-consuming.
The attacker attempts to guess the login password, using multiple scripts Chinese Student Phone Number List running simultaneously. These scripts test multiple combinations via the xmlrpc.php functionality, a remote call procedure active by default on every WordPress installation, but not only, which uses HTTP as transport and XML as encoding, effectively allowing communication between the CMS and other systems . One of the brute force attack variants is the dictionary attack . In this case the hacker uses a certain number of strings, composed of words contained in the dictionary, provided to the software. An attack of this kind can also be used in an attempt to find the key needed to decrypt an encrypted message or document.
This system can be effective if users choose simple passwords, often to avoid forgetting them. These attacks, in fact, are unlikely to be successful against systems that use passwords made up of multiple words or against passwords with uppercase and lowercase letters accompanied by numbers. One tool that allows the creation of dictionaries for brute force attacks is Crunch , a word list generator capable of forming tons of combinations. Brute force attack software There are several programs used for brute force attacks, including: JohnTheRipper (JTR) . Open source software, performs standard brute force attacks and dictionary attacks. It also allows you to trace the type of hash used. Hydra . It is one of the most used software for brute force attacks. It is particularly efficient in searching for remote authentication credentials, supporting various protocols including SSH, MySQL, HTTPS. Hashcat .
