Have you had any experience with detecting shells using CXS? I currently have the free version of imunify + CXS.
Adding extra signatures such as malware.experts for clamav or free ones from interserver can improve the performance of CXS in detecting shells.
However, Imunify360 is a monthly paid product and offers more frequent updates compared to CXS which is a one-time payment product. Both have their strengths and we use both, but CXS does require more configuration to ensure proper functioning.
If the main requirement is detection, ImunifyAV can be used as it possesses the capability to detect almost everything that Imunify360 does.
ImunifyAV is an antivirus designed for websites that can easily detect any malicious script and remove it with a single click.
It supports various PHP CMS including WordPress, Joomla!, Magento, Drupal, MODx, Bitrix, as well as static HTML sites. It comes with a variety of features such as scheduled scans, notification alerts, and flexible service settings. ImunifyAV is capable of detecting different types of malware including backdoors, web shells, trojans, black hat SEO, phishing pages, etc. It is easy to set up and can be scheduled to work automatically. The paid version of the module costs $5/month, with a free version also available (with limited features).
It can be used as a module of the ISPmanager panel.
The free version of imunify + CXS is a powerful tool for scanning files and detecting potential threats, including web shells. It's important to keep in mind that CXS provides a comprehensive approach to security by scanning files for malicious code, backdoors, and suspicious patterns.
When using CXS, it's crucial to set up regular scans and review the scan reports thoroughly. Look for any flagged files or suspicious code that might indicate the presence of a shell. Keep in mind that while CXS is an effective tool, it's also essential to implement other security measures to protect your system.
The combination of CXS with regular security updates, strong password policies, and secure coding practices can significantly enhance your website's security posture. If you encounter any suspicious activity or believe that a shell may have been detected, it's advisable to take immediate action and investigate further to mitigate potential risks.
In addition to signature-based detection, CXS employs heuristics to identify potential security threats. It analyzes file contents and metadata, looking for anomalies or patterns commonly associated with web shells. When a suspicious file is detected, CXS can generate detailed reports, indicating the nature of the potential threat and its location within the file system.
To make the most of CXS, it's essential to stay informed about the latest malware trends and attack techniques. This knowledge allows you to refine your scanning strategies and better understand the evolving nature of web-based security threats.
Furthermore, regularly reviewing the CXS scan reports and taking prompt action upon any detections is crucial. Swiftly addressing potential security risks helps mitigate the impact of malicious activities and contributes to maintaining a secure online environment for your website and its visitors.
