Ransomware Detection:

 The dynamic behavioral engine now detects more suspicious activity related to ransomware. A new ransomware detection engine drops decoy files that are used for detection purposes. By default, these decoy files are placed in specific directories, defined in the decoy_files_predefined_paths config key, if the directory exists. The predefined directories are: /home/*, /var/www, /var/www/html, /var/lib, /var/lib/www,/var/lib/mysql, /srv, /root, /usr/share, /usr/share/nginx/html,/usr/local/share, /usr/local/apache2, /etc/nginx, /etc/mysql, /etc/httpd, /etc/apache2.

These decoy files are hidden files, named .aaa.pdf, .aaa.ini, .aaa.log, and .aaa.html.

But that’s not all:

  • Logs from the Log Fetch command now show the date in UTC and output from hostname -f, hostname, and dnsdomainname.
  • Added support for CentOS 8.4
