This is the latest release of Trellix Malware Analysis

New features and changes

This section describes new features in Trellix Malware Analysis release 11.0.0.

  • Support OS Upgrade to Alma Linux 9.2

    The Malware Analysis platform has undergone a base upgrade from CentOS 7 to Alma Linux 9.2 to ensure continuous support and deliver improved stability, security, and performance.

  • Malware Repository Analysis supports enabling/disabling VNC through the WebUI and CLI

    The Malware Repository Analysis feature now supports the enabling and disabling of Virtual Network Computing (VNC) sessions directly through the WebUI and CLI. This functionality allows users to automate the initiation of VNC sessions for all malware repository submissions, regardless of whether they are initiated from the WebUI or CLI.

  • Integration with private Global Threat Intelligence (pGTI)

    The Malware Analysis appliance now supports Private Global Threat Intelligence (pGTI) integration, enabling it to leverage Trellix's private cloud server for URL and file reputation verdicts. pGTI, which uses REST APIs and certificate-based authentication, maintains reputations based on Trellix security platform submissions. Malware Analysis can now query pGTI for file and URL reputation assessments during analysis.

  • Support provided for custom IOC feed implementation through the Web UI

    Enhancements have been implemented to the Malware Analysis Web UI, enabling the inclusion of URLs, MD5 or SHA-256 hashes, and regex URLs within both allowed and blocked lists. These additions are designed to optimize the appliance's detection efficacy and expedite analysis times.

  • Integration of external threat intelligence feeds through the TAXII protocol.

    Malware Analysis now integrates third-party threat intelligence feeds from TAXII servers using STIX 2.x/TAXII 2.1 via the web UI and CLI. Upon configuration, the system automatically retrieves feeds, including URLs and file hashes, at scheduled intervals based on the configured synchronization frequency. Currently, Malware Analysis supports the configuration of a single TAXII server, with customizable API roots, credentials, CA certificates, synchronization frequency, and STIX indicator types.

    Important

    For more details, see "Managing threat intel feeds using TAXII".

  • Custom URL rules now support regex pattern matching

    Regular expression pattern matching is now supported for custom blocklists and allowlists, enhancing the ability to define URL rules. This enhancement provides increased flexibility for improved threat management via both the Command Line Interface (CLI) and the Web User Interface (WebUI).

  • Improved Third-Party Feed management capabilities

    The 3rd Party Feeds page, formerly exclusive to Malware Analysis, is now extended to the Central Management System. This enhancement allows users to add, view, and download feeds from the Web UI of either product. Additionally, new Allowed Lists and Blocked Lists sub-tabs are implemented in both products. These tabs enable the management of entries, including the ability to add, view, update, and delete based on URL, MD5sum, SHA256, and Regex URL criteria.

  • Malware Analysis now offers full analysis of Dropper Files

    Enhanced file analysis by processing dropper files with built-in safeguards against infinite execution. Implement a submission-level threshold to limit the number of dropper files undergoing full analysis (default: 1). Exceeding this threshold will exclude subsequent dropper files from comprehensive analysis. Additionally, perform Domain Under Analysis (DUA) on URLs extracted during Dynamic Analysis (DA).

Upgrade support

The Trellix Malware Analysis 11.0.0 release requires a reboot for the update to take effect. You can upgrade your AX appliance to 11.0.0 from release 9.1.0 or later.

After an upgrade to version 11.0.0, the dashboard will not retain prior data for Analysis Statistics and File Analysis Statistics.

After an upgrade to version 11.0.0, the dashboard statistics may may exhibit inaccuracies for the initial three-hour period. Scan statistics remain unaffected.

Previously created log archive files shall not be preserved during an upgrade to 11.0.0. It is recommended to secure a backup of logs before initiating the upgrade.

After any upgrade to 11.0.0, the FireEye Advanced URL Defense Engine (FAUDE) will be activated if it was previously disabled in earlier versions. See "Enabling or Disabling Advanced URL Defense" in the Malware Analysis User Guide.

After upgrading to version 11.0.0, certain system processes may remain in a pending state until the latest security content has been successfully downloaded and installed. See the following section, "Download the security content bundle".

Download the security content bundle

After the upgrade, certain processes will be in a pending state until new security content is downloaded and installed. The security content is downloaded and installed automatically for online customers. Offline customers must manually download and install the new security content after upgrading appliances to release 11.0.0.

Downloading content from the DTI offline update portal

If acquiring Malware Analysis 11.0.0 security content from the DTI Offline Update Portal, utilization of the SCNET-9.0 channel is mandatory.

Caution

Deviation from this specific channel for security content retrieval will invariably precipitate a compromise in detection capabilities.
