    hostname > enable

    hostname # configure terminal

  2. Begin the upgrade:

    hostname (config) # ipmi firmware update latest

  3. Confirm the upgrade:

    hostname (config) # show ipmi

If the upgrade fails, try the steps again.

If IPMI functions are not fully restored, perform a full power cycle (cold shutdown) on the appliance:

  1. Stop the reload process:

    hostname (config) # reload halt

  2. Disconnect all power cables for 2 minutes.

  3. After 2 minutes, reconnect power cables and restart the appliance.

YARA rules supported versions

YARA rules support version 4.3.2.

Important

Before you upgrade an Malware Analysis appliance to the 10.0.2 release, modify any custom YARA rules to YARA 4.3.2. For details about YARA 4.3.2, see YARA's Documentation, Release 4.3.2 by Victor Alvarez.

Enabling access to intel context

Advanced Threat Intelligence (ATI) is a cloud-based data collection and threat intelligence distribution feature that provides actionable information about MVX-verified events on appliances. The threat intelligence tells you who is the threat actor behind an attack, what has been targeted or breached, and (if known) how to mitigate the threat. The Trellix Research Labs team continually uploads the latest threat intelligence to the Trellix Dynamic Threat Intelligence (DTI) cloud. When an MVX-verified event triggers an alert, the appliance queries the DTI server for threat intelligence and stores the additional information in its database. When you display an ATI alert, the alert details include the threat intelligence.

Appliances now need access to the Amazon Web Services (AWS) cloud for ATI communication. The intel context service is hosted in multiple AWS regions and resolves to multiple IP addresses based on geographic location. To determine the IP addresses for your location, go to https://dnschecker.org. See the AWS IP address range documentation for information about adding the IP addresses to the allow list.
