Why websites are hacked
In 2023, the number of cyberattacks continued to grow both globally and in Russia. Globally, the level increased by 37% ( SourceSecurity ), which affected both companies and ordinary users. Attacks on Internet-connected devices (IoT), i.e. smart cameras, thermostats, home appliances and even medical devices, reached 77.9 million in the first half of 2023, which is due to their increased use and insufficient protection ( Kaspersky ).
In 2023, more
content writing service than 29,000 phishing (fraudulent) domains were discovered in Russia. A fivefold increase in compromises (breaches of confidentiality, integrity) of accounts of large Russian banks using stealers — programs that steal information from devices — was also recorded ( ICT Moscow ).
All these facts indicate a growing interest among criminals in stealing personal data both in Russia and around the world.
Hacking websites has become a real problem for business owners, developers and anyone who operates online. But why is it done? There are many options: theft of personal information, financial gain, use of server resources for illegal activities or even the desire of hackers to test their skills.
Types of hacking that cause serious damage to the functionality of a web resource
SQL injections. This type of intrusion allows a hacker to inject their code into requests to the information storage system, which can lead to a leak of confidential information. Typically, such vulnerabilities are found in poorly protected information entry forms. SQL injections are used to gain unauthorized access to databases. The main goal is to steal or change confidential information, passwords, credit card numbers. In addition, with the help of SQL injections, you can gain access to administrative accounts, fully control the resource and make any changes to its content by intruding into installation algorithms. A very painful option that allows you to get to many of the company's systems.
DDoS attacks. Their goal is to overload the server with requests, making the site inaccessible to visitors. This is the most common method when attackers want to disable Internet pages without direct hacking.
At AdminVPS hosting, all hosting plans provide clients with protection of web resources from DDoS attacks.
In addition, hosting from AdminVPS is:

Brute force. This is a method of selecting passwords for various accounts. Profiles with simple options like "123456" or "qwerty" are especially vulnerable. If an attacker manages to hack administrative access, he gains full control over the resource.
XSS (cross-site scripting). The attack occurs through the introduction of dangerous programs into the pages of the site, which allows changing its content or gaining access to visitor sessions.
Module and CMS vulnerabilities. Projects running on popular management systems, such as WordPress, can become victims through outdated or vulnerable modules. These vulnerabilities allow attackers to penetrate through holes in the security system. Hackers gain control over the resource, steal personal information of visitors, and place fake pages for phishing.

It is within your power to protect your network project from the listed threats, acting independently or with the help of professionals.
Methods of protection
From SQL injection
What to do yourself: If you use popular CMS, such as WordPress, install additional security modules (plugins) that already include protection against SQL injections (Wordfence).
Instructions for protecting CMS WordPress from SQL injections
Here is an example of step-by-step instructions for activating automatic protection settings in WordPress.
Installing the security tool:
In your WordPress dashboard (yourwebsite.com/wp-admin), on the sidebar, select “Plugins” and then “Add New”;
In the search bar, enter the name of the security tool, for example, Wordfence Security, and click the Install → Activate button.
Security settings:
Once the tool is activated, a new section called Wordfence will appear in the sidebar. Click on it.
Select Scan for vulnerabilities.
Next is the “Firewall” option for working with security settings.
Turn on threat notifications to stay informed about new potential issues.
Do not forget to regularly update the security module (plugin), create backup copies of information.
What the specialist will do: implement prepared expressions into the code and parameterized queries, which will protect your site from SQL injections. Conduct a code review, identifying vulnerabilities and ensuring security.
DDoS protection from AdminVPS
From DDoS attacks
But for larger platforms, you will need to connect firewalls, specialized protection services such as Cloudflare or Akamai, which offer advanced DDoS protection solutions. A professional will help with this.
Hosts like AdminVPS include DDoS protection in their plans. AdminVPS offers this feature for free on all hosting and VPS/VDS plans . Check with your provider to see if they offer this option.
From XSS
To provide a basic level, you can use security modules that offer filtering of user input.
What to do yourself. Use tools that monitor and filter user input. For example, you can install a protection system that automatically cleans input data from malicious code. Many content management platforms have built-in functions for filtering and processing user input.
In WordPress, these are Sucuri Security and Wordfence Security. To connect them, go to your site's admin panel, select "Plugins" and click "Add New". In the search bar, enter the name of the plugin (Sucuri Security or Wordfence) → "Install", and then "Activate". Go to the plugin settings and set the necessary user input filtering parameters.
If you have specific requirements for handling user input or you are not confident that you can handle it yourself, it is better to seek help from a web developer or security specialist.
Passwords
Create complex passwords or use their generators - LastPass or 1Password . Such programs help to create complex passwords for each of the accounts, save them for you. They can automatically fill in forms, enter your data on sites, which saves time and reduces the likelihood of error.
If you need to set up 2FA (two-factor authentication) for more complex systems or do it on a company-wide level, you will need the help of an IT specialist.
Updating plugins and CMS
Regularly update both plugins and the CMS itself. Many systems can update automatically, which simplifies the process of protecting against vulnerabilities.
How to check the level of protection of a website
To find out how well a project is protected, use special vulnerability scanning solutions.
OWASP ZAP is a free and open source vulnerability scanning tool that can be used to find vulnerabilities in web applications and is used by both developers and security professionals.
Nessus is a professional security scanner that offers paid versions, although a limited free version with basic features is also available.
Snyk offers a free option for small projects, but more advanced features require a paid plan.
Resource security is not a one-time task, but a whole marathon, where you can’t do without regular updates, traffic monitoring, systematic checking for vulnerabilities. Don’t forget about this, so that hackers don’t make Swiss cheese out of your site. _________________ content writing service |
