3.5.0 Release notes - 10 August 2018

Wazuh core

• A new integration with osquery is shown, this will provide new scheduled results for the manager:

  • The osquery daemon will be launched in background.

  • Filter events by osquery by adding a new option in <location> rules.

  • Enrich osquery configuration with pack files aggregation and agent labels.

  • Support folders in shared configuration.

• Parallelized remoted daemon:

  • Up to 16 parallel threads to decrypt messages from agents.

  • Frequency of agent keys reloading limited.

  • Message input buffer in Analysisd to prevent control messages starvation in Remoted.

• Vulnerability Detector has been enhanced, adding support for other operating systems and improving the configuration of OVAL updates.

  • Added feed tag for updating each operating system OVAL, allowing to set a different configuration for each of them.

  • Packages already scanned won't be checked unless no Syscollector scans are detected in a period longer than 24 hours.

  • Added arch check for Red Hat's OVAL.

  • Force the vulnerability detection in unsupported OS with the <allow> attribute.

• Fixed alerts format in Vulnerability Detector. When showing Vulnerability Detector alerts from a Red Hat agent, an RHSA patch was shown instead of a CVE. This patch consists in various CVEs compressed. The RHSA patches are unpackaged and alerts manifest that the system is vulnerable to each of the CVEs contained in that RHSA.

• Added new support for AES encryption for manager and agent.

• Enhanced active response process. Added a new feature which allows the user to customize the parameters sent to the agent's active response script.

• Added synchronization for remoted counters (rids), being reloaded if the inode of the file has changed.

• Windows deletes pending active-responses when an output signal is received.

• Rootcheck searchs for 32-bit and 64-bit keys. As Windows agent only runs in 32-bit mode, by default Rootcheck was searching only for 32-bit keys.

• Get Linux packages, DEB and RPM, for Syscollector.

• Added a new module for downloading shared files for agent groups dynamically.

• Get running processes, opened ports, network interfaces, Linux (DEB/RPM) and Windows inventories natively for Syscollector.
