There are many methods that can have a detrimental effect on a system and cause many problems for system owners, in order to be able to increase the security of your system , you must be familiar with all these methods and increase your information security by mastering them completely, hackers may use malicious code to achieve their goal in such a way that the users click on it and lose the security of their system easily, in this case, they provide hackers with all of their information which allows hackers to abuse it in order to achieve their desires, there are a number of malicious codes that if the users enters the page where these codes exist, they will infect their system, which we will discuss in more detail in the following.
There are methods of hacking the site in which the users may not realize that their information has been stolen and do not take any action, so hackers can infiltrate more user systems and access their information easily.
What is Cross-Site Scripting?
- It allows the hacker to give messages from the userís system to others with the content they want.
- The hacker can access the facilities available in the user's system, such as the microphone, the user's geographical location, etc., and use them in order to inflict malicious damage.
In general, these attacks have different types, which we are going to mention in the following:
Types of XSS:
- Stored XSS (Persistent XSS):
One of the most malicious codes that hackers use to steal users' information is Stored XSS , which hackers enter in the user input section, such as the blog comments section or in a post, and finally the user's system is infected as soon as they log in.
In order for this code to be activated, logging in to the page where the code is located is enough and as soon as the user enters the target page, the malicious script will run, in fact, the users may not be aware that their system information is being destroyed or stolen, and after a while, they may recognize suspicious cases, and conclude that something has happened in their system, but it may be too late.
- DOM-based XSS:
Another things that users use in order to increase the security of their site are firewalls that increase the security of the system significantly and keep user information in a safe place, although there are many cases that despite the use of firewalls, hackers can still cause malicious damage to information through them, one of them is DOM-based XSS, this kind of attack is very difficult to analyze even for web application firewalls, because they cannot even observe the attack, in fact, this is one of the most advanced XSS attacks and can do a lot of damage to system security.
- Reflected XSS (Non-persistent XSS):
Another type of XSS attack is one in which many hackers use it to attack users' systems, through this type of attack, malicious code must be placed where the user requests, along with this method, hackers also use social engineering to somehow force the user in order to make the request which activates the code and eventually abuse user information, so these types of attacks are more common in social networks and, as mentioned, are implemented in combination with the social engineering method.
Should we take XSS attacks seriously?
In general, you should take any case that may harm the security of your system seriously and do your best to be able to increase the security of your system and information by mastering all the topics in site security , one of the things that you should take seriously is XSS attacks , which can cause a lot of damage to various systems, through these attacks, sites which were trusted by users turn into malicious sites that cause irreparable damage to systems, eventually the credibility of the site is reduced and the users will never return to it again, as a result, the site will stick to usersí mind as a malicious site, and they will definitely share that bad user experience with their friend in order to make them aware of the threats that using your site may bring, so it causes a huge decrease in the number of your website users.
In fact, by entering such sites, the users may inadvertently download software or view items that they have not even clicked on, all of which are dangerous to the user as well as the site's credibility and should be avoided, therefore, you should pay attention to the occurrence of such cases so that you do not face their destructive effects, to see how resistance your system is to such attacks, you can use the available tools to check the security of your system so that hackers cannot access your information easily and if they want to gain access to the information in your system, they need to do a lot of activities that may eventually deter them and make them look for a lower security system in order to get their desired result more easily.
-Website owners, in order not to lose the trust of users who visit your site, should clean the input strings, so that the users are not going to be attacked by hackers when they enter their site, it is also necessary for the site owners to scan all the suspicious items on the site and fix them before causing irreparable damage to the site's reputation.
- The users should be careful not to click on any link they see on the site, and if they recognize a suspicious case, try to report it to the site owner immediately, so that other users who visit the site, will not face with such cases.
- Another point that the users should pay attention to, is that they should disable scripting in their browsers, which can help a lot to increase the security of information in the user's system.
- Users should refer directly to the sites they intend to visit, and do not enter them through links in other sources or through a third party source.
In general, hackers use new methods in order to achieve their goals, one of the most important and practical methods that is widely used by attackers is XSS attacks , in this article, we tried to summarize this issue, so that you can increase the security of your system by mastering this issue and becoming more aware of the possible threats.
