Key takeaways

Some of the key findings from our 2023 Website Threat Research Report include:

  • 39.1% of all CMS applications were outdated at the point of infection.

A CMS was considered outdated if it had not been updated with the latest security release at the time remediation was performed. Our data indicates that automatic updates in WordPress have aided in maintaining more up-to-date CMS installations, which has significantly reduced exploits in core CMS vulnerabilities.

  • 13.97% of all compromised websites had at least 1 vulnerable plugin or theme present in the environment at the point of remediation.

This data point stresses the importance of patching and maintaining website software and third-party components to mitigate risk. Easily exploited vulnerabilities are a top choice for attackers. If they don’t require authentication, attackers are able to easily automate their attacks and monetize affected environments. By patching software to the latest version, website owners can minimize risks from bugs, known vulnerabilities, and other security threats.

  • 49.21% of compromised websites were found to have at least one backdoor at the point of remediation.

Closing thoughts

The data from our 2023 website malware and threat report highlights the importance of keeping CMS applications, plugins, and themes up-to-date to reduce the risk of infection. The high percentage of outdated CMS applications and vulnerable plugins or themes present in compromised websites suggests that there is still work to be done in terms of patching and essential security practices to prevent infection.

To combat these threats, website owners and developers must prioritize website security, leverage 2FA on admin panels among other website security best practices, and stay informed about emerging trends and attack vectors. You can leverage a web application firewall like the Sucuri WAF to help mitigate risk and protect your website from unauthorized access, brute force, and website malware infections.
