If you are a little familiar with hackers, you know that these talented people only want to get whatever they want as soon as possible, and in this way, they remove any obstacle and do not allow anything to stop them achieving their goal, in fact, as security progresses, the methods they use in order to disrupt security improves as well, so they try to update their information in this field, and they never give up trying to achieve their goal, one of the most common method among hackers is SQL injection , which many of hackers use it to infiltrate various sites in order to access a lot of information through it, of course, site owners are trying to increase the security of their information by taking various measures which can help them in this way.
What is SQL injection?
One of the most common types of hacking methods is attacking sites, in which hackers use existing tools to investigate security vulnerabilities as well as existing coding problems, and ultimately, attack the system security through these ways, this method is very simple and even novice hackers can use it in order to access the information on the sites, weaknesses in web code can also indicate root access to web servers, which can lead to attacks on other network servers.
In fact, SQL stands for Structured Query Language, which allows hackers to gain access to a lot of information, this attack can also disrupt firewalls, which ultimately let them achieve their purpose, and you should be aware that any form of web that is not properly encrypted may allow hackers to access your data by injecting SQL, it should be noted that hackers are very interested in this method and frequently use it in order to hack different systems.
Types of SQL Injection:
- In-band SQLi (Classic SQLi):
Two common types of this injection are Error-based SQLi and Union-based SQLi.
- Inferential SQLi (Blind SQLi):
Two types of this injection are Boolean-based (content-based) Blind SQLi and Time-based Blind SQLi.
- Out-of-band SQLi
How to hack using SQL injection?
In all sites, there are a number of forms through which users may enter their important information on the site, so all users have access to various forms available on the site, and these forms are sent to your system and is provided to your database, in SQL injection , hackers actually use these forms and insert the SQL statement into the parts of your form instead of the expected data, finally hackers can access and exploit the information they need in the database, in addition to survey forms that may be completed by hackers with the SQL command, there are other ways through which they can hack, generally the parts that provide web page content is vulnerable to SQL injection attack and can get the hacker to their destination which is having access to users’ data.
Why would a hacker want to use SQL injection?
In fact, hackers are looking for a way to hack that can get them what they want quickly and are less likely to fail in their choice, which is why many of them turn to SQL injection for hacking, as we have mentioned before, in order for SQL injection to be successful, it is necessary that the encryption in various parts, especially the forms and parts where users can enter information, is not done properly, and finally from this way hackers can enter the database, and gain access to the information they want, on the other hand, databases, control many of the website's functions, and if hackers can access the database, they can actually take a lot of action against the security of site , another important point that studies on security vulnerabilities on various sites by existing scanning tools have shown is that more than half of the sites have coding problems and hackers can use SQL injection easily access the information you want and change the various functions on the web in order to achieve their desires, so they are looking for a security hole in order to infiltrate it and can gain access to the important and sensitive data, and as we have mentioned they try to find various ways in order to get the things that they are planning to achieve.
What is the reason for increasing SQL injection?
As you probably know, one of the techniques used to increase the ranking of sites on the search engine results page is to increase user interaction, and on the other hand, all sites tend to be able to get more organic traffic to their websites , as a result, all sites have placed boxes on their site for giving this opportunity to users to ask questions and get their answers, so they can have interaction with users, they may also put many survey forms on the site, etc., all of which help hackers to be able to attack more sites and use more users' information in order to achieve their desired results, hackers are trying to find more and more programs and services through which they can carry out their desired attack and access databases in order to disrupt all existing functions and change their function to get whatever they want through these changes.
What sites are most at risk from this attack?
Before hacking a site , hackers examine whether it is worth spending time hacking the site or not, in fact, as it is known, sites that contain political information or have social value, etc., as well as old and large sites are more attractive to hackers, and they usually prefer to hack such sites over the small ones, and after reviewing their security vulnerabilities decide to hack the site, or they may decide to hack another site and choose the one that has very low security and incorrect encryption, so they prefer to hack them and create problems in their performance, these attacks are carried out slowly and carefully, so that site owners are not aware of the hacking process, and finally they can continue to work for a long time and by accessing the database, they will be able to access all the functions of the site easily, and use them to achieve their desires.
What should we do to deal with such attacks?
There are many ways that site owners are offered to increase the security of their site , one of which is, firewalls, which, as you know, can significantly increase the security of the site, but firewalls can't protect databases and sites from SQL injection attacks, and these attacks can easily break down these firewalls, as a result, we have to use other ways to increase the security of the site against such attacks, which we can mention two things that have a great impact on increasing the security of the site against such attacks, one of which is to check the written code, as we have mentioned earlier, hackers search to find the wrong encryption on a site and eventually infiltrate it, and another way they can choose is to increase the security of the site by updating programs constantly to reduce the security holes in them, greatly reducing the way for hackers to infiltrate.
In general, hackers may use different methods to hack different sites, one of the most common methods used today is SQL injection, in which, as we mentioned in this article, hackers use SQL commands to hack sites and enter these commands into the registration forms on the sites, so that they can access the information in the site's databases, in this article, we mentioned the reason why this method is very common among hackers, and they use it extensively, due to the fact that even firewalls which are commonly used among users in order to increase the security of their information cannot protect them from being hacked, so other ways are mentioned in this article which can help you increase your information security , that if you use them properly, you would be able to protect your data from this kind of attack which is a strong method that is widely used among hackers because of its power in damaging the system.Click to audit your website SEO
