Every day, thousands of WordPress websites become targets for cybercriminals. Vulnerable plugins, outdated themes, weak passwords, and newly discovered security flaws allow attackers to upload malicious code, web shells, SEO spam, backdoors, and other dangerous files.

In many cases, website owners are completely unaware that their site has been compromised. Malware can remain active for weeks or even months while secretly redirecting visitors, sending spam, creating hidden administrator accounts, or providing attackers with full control over the server.

Hi guys, I’d like to share some significant signals that tell about infection on a WordPress site. These data has been collected by our research team at CleanTalk. The team reviews up to 10k files weekly as well as we

CSRF (Cross-Site Request Forgery) is a type of web application vulnerability in which an attacker tricks a user into performing an unwanted action on a site where the user is already authenticated.For WordPress sites, this vulnerability can be exploited by unauthorized changes to site settings, content publishing, or even administrative actions.

CSRF vulnerabilities in WordPress can occur when developers misuse protection mechanisms or ignore them altogether. Despite built-in tools to prevent CSRF, implementation errors can make the application vulnerable. Let’s take a closer look at the main scenarios, vulnerabilities, and their exploitation.

Malicious code is quite common on WordPress sites and complicates the lives of users with the functionality of the website and its capabilities, even to the point that malicious code can have serious destructive effects.

A file was found in the YouTube Embed Plus plugin for WordPress youtube.php in which the attacker wrote malicious code that may pose a security threat to sites. This code allows attackers to gain access to site settings and data through various mechanisms, such as unauthorized changes to plugin settings or the introduction of hidden code. Let’s take a closer look at what this malicious code is and what measures can be taken to protect against possible threats.

SQL injection in WordPress plugins is a vulnerability in which an attacker can inject and execute malicious SQL code in the site database. This usually happens if user input (such as form data or URL parameters) is not sufficiently checked or filtered before being used in SQL queries.

Cross-site scripting (XSS) vulnerabilities occupy one of the first places in terms of frequency among the vulnerabilities found in WordPress plugins. These vulnerabilities occur when data from a user is not sufficiently cleaned before being displayed on site pages, which allows attackers to inject malicious code such as JavaScript and execute it in visitors’ browsers. XSS attacks can lead to theft of user data, hijacking of sessions, modification of page content, and other types of malicious activity

Our research team discovered a new type of tricky malware that modify cron to re-infect a WordPress site. It causes some problems because of unusual way of infection. Cron is a task scheduler in Unix-based systems that allows specific commands
