ConfigServer eXploit Scanner (cxs)

ConfigServer eXploit Scanner (cxs) is a tool from us that performs active scanning of files as they are uploaded to the server. Initial installation with recommended configuration options is included with the license.

 Actively scans all modified files within user accounts using the cxs Watch daemon regardless of how they were uploaded

 PHP upload scripts (via a ModSecurity hook)

 Perl upload scripts (via a ModSecurity hook)

 CGI upload scripts (via a ModSecurity hook)

 Any other web script type that utilises the HTML form ENCTYPE multipart/form-data (via a ModSecurity hook)

 Pure-ftpd uploads

The active scanning of files can help prevent exploitation of an account by malware by deleting or moving suspicious files to quarantine before they become active. It can also prevent the uploading of PHP and perl shell scripts, commonly used to launch more malicious attacks and for sending spam. cxs also allows you to perform on-demand scanning of files, directories and user accounts for suspected exploits, viruses and suspicious resources (files, directories, symlinks, sockets). You can run scans of existing user data to see if exploits have been uploaded in the past or via methods not covered by the active scanning. It has been tuned for performance and scalability.

Purchasing: cxs is a commercial product that is sold and licensed on a per server basis. Unlike competing products, it is strictly a one-time per server license purchase with updates for the life of the product, all at a reasonable price! Initial default installation on a single server per license is included in the price. Please see the FAQ for more information about discounts and installation.

Exploit detection includes:

 Over 4000 known current exploit script fingerprint matches (in addition to standard ClamAV detection)

 Known viruses via ClamAV

 Regular expression pattern matching to help identify known/unknown exploits

 Filename matching

 Suspicious file names

 Suspicious file types

 Binary exeuctables

 Some illegal web software installations

 Custom user specified regular expression patterns

 Comprehensive constant scanning of all user data using the cxs Watch daemon - scans all user files as soon as they are modified

 Daily check for new Exploit Fingerprints

 Check for old version of popular web scripts (e.g. WordPress, Joomla, osCommerce)

 Bayes probability scanning - scans scripts and passes the contents through an algorithm which produces a probability as to whether it is an exploit

 Monitor files and directories for changes and send an email report of activity

 IP Reputation System. The system provides a variety of IP blocklists gathered from information that is submitted by participating servers. This dual aspect provides the information to help protect the server using the reputation from active attacks

 Major update to Script Version Scanning. cxs now scans for more than 200 individual applications, more than 200 WordPress plugins and more than 200 Joomla Extensions. Over 700 in total!
