Many sectors in the human race are being digitized; websites are now becoming a hub for storing data and information. This convenient means can be said to have taken over classifying data via paper and pencils.
This digital age still, however, presents its risks. Website hackers can attack your website in various ways.
For prevention purposes, you have to understand how the attacks happen
Cross-site scripting (XSS)
Cross-site scripting is a major vulnerability that hackers often exploit for website hacking. Unfortunately, it is one of the more difficult vulnerabilities to deal with because of how it works.
There are three main types of XSS attacks:
- Reflected XSS; in this case, the corrupt script comes from the HTTP request.
- Stored XSS, the corrupt script comes from the website’s database.
- DOM-based XSS, where the entry window exists only on the client-side code and not the server.
To avoid XSS attacks, users must carefully filter their inputs on various websites.
THROUGH SQL INJECTIONS
SQL means structured query language. It is used to interact with databases. It also allows the website to create, retrieve, update, and delete database records. It is used for everything from logging a user into the website.
This website hacking technique is a very common one. An SQL injection attack places SQL into a web form to get the application to run it.
Wikipedia says, “SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution” This can allow a hacker to gain access to a restricted section of a website. Other SQL injection attacks can be used to delete data from the database or insert new data.
SQL injection attacks allow these attackers to spoof identity and mess with the existing data; this attack allows them to change or erase any data on the system. The attackers can also make it unavailable so that they become the admin of the data. This malicious attack has affected so many websites, both present, and past.
An example is the 2005 Taiwanese information security magazine hack, where a teenager used an SQL injection to break into their site and then stole customers’ information. This presented a huge flaw in their security.
Non-targeted website hacking techniques
This method is an indirect method of website hacking. Occasionally hackers won’t categorically target your website as a whole. Still, instead, they look for a window that exists in a (CMS) content management system that you make use of, e.g., an installed plugin or a template. So attackers will develop a code or technique that targets the weak spots of a particular version of your WordPress, Elementor, Joomla, or any other CMS you’re using. These hackers can easily use automated bots to find the websites using the specific or infected version of the CMS in question before launching an attack. This breach in your website can lead to massive loss of data from your website, loss of private information, or insert malicious software onto your server.
To avoid this hacking technique, you must ensure that you get your plugins from a secured and trusted store and make sure your plugins and template are in their best version, i.e., up to date.
DNS spoofing (DNS cache poisoning)
DNS cache poisoning is a form of website attack in which DNS records are altered and are used to redirect online traffic to a hacker’s website that looks like its intended destination. In addition, DNS spoofing tricks the user into believing that they are interacting with a secured domain name, not knowing that a fraudulent website has hijacked the online traffic.
Cache poisoning is a method aimed at gaining control of the answers stored in the DNS cache. This is a more specific type of attack that targets cache name servers. There are different methods to carry out this attack. To successfully carry out such an attack, hackers find a penetrable service code, which gives them access to fill the HTTP header field with many headers.
Then forces the cache server to flush its actual cache content. After which they send a specially designed request, which will be stored in the cache, the attacker makes another request that will always be available because of the previously sent cache.
This attack is very difficult to detect, and if successful, the damage can be catastrophic. The attackers can impact thousands of end-users who use the recursive name server that holds the injected contents.
Preventing an attack like DNS spoofing or cache poisoning is done by limiting the answers to DNS requests.
However, this does not eliminate the attack, but further encryption and reducing your TTL values, i.e., the TIME TO LIVE value of a particular data, can also prevent this. You can look into http://cybersploits.com/ to contact professional hackers for this encryption.
Cross-site request forgery (CSRF or XSRF)
CSFR is a common malicious exploit of websites. It occurs when unauthorized commands are transmitted from a user that a web application trust. For this to be effective, the user must be logged in and verified by a website. This allows the attacker to obtain account information and transfer funds or gain access to sensitive information.
This digital age puts a lot of websites in danger of the risks mentioned above. At ThehackersPro, provide adequate security by professional white hat hackers to give you an assured sense of peace when it comes to securing your website.
