Release Notes

11.2.0​

Version 11.2.0 is a small group of fixes to resolve bugs found in the latest azul deployment.

fixes​

webui​

  • loading icons in similar ssdeep and similar TLSH would never go away if no matches were found
  • remove animation when a binaries data tab is loading as it may never load
  • fixed issue with retrohunt display not showing multiple rule results and failing to pickup yara rule names.
  • hex and string view are now always the default views on data page.

restapi​

  • fixed issue where binaries with lots of augmented streams lose access to their content via azul restapi

audit forwarder​

  • Add byte limit for cloud watch logs.

plugin-yara​

  • fixed a bug where if too many yara rules hit on one file ingestion would fail, the yara hit streams are now dropped above 50 streams.

11.1.0​

Version 11.1.0 adds some fixes for the infrastructure deployment of azul as well as fixes for git-sync when using ssh.

azul-app​

infra​

  • infra for opensearch and kafka have been upgraded to work with the latest version of strimzi and the opensearch operator.
  • installation docs have been improved to make the readme for infra available through the azul-docs.

fixes​

  • git-sync was failing when using ssh as the auth method. This has been fixed in the chart.

Plugins​

Maco​

azul-plugin-maco was updated to use the newest version of maco (1.3.1)

11.0.0​

Version 11.0 introduces new core features, focusing on enhanced capabilities and improved ease of use through the Azul UI.

Improvements include:

Core​

azul-app​

  • Added a liveness check for all plugins.

audit-forwarder​

  • Added dynamic windowing to better handle bursts of logs.
  • Included additional information in the log format.

metastore/restapi​

  • Added docand grammar to enable more precise searches
    (e.g searching for depth:0 DOCAND source:"testing" it ensures the depth is actually 0 with the source and not just that a binary has depth 0 somewhere and testing somewhere)
  • Introduced entropy similarity, enabling searches for similar binaries based on entropy graphs
    (disabled by default due to potential crashes in older OpenSearch clusters using the FAISS plugin).
  • Fixed an issue where plugin features and statuses were not always from the latest plugin version.
  • Added an API to find common strings between two binaries.
  • Introduced a download API, allowing users to request hash downloads via plugins.

azul-dispatcher​

  • Added a maxSecurity filter to prevent plugins from collecting jobs above a specified classification level.

azul-client​

  • Improved help information to make the client more user friendly.
  • Updated to match the API that renamed similar to similar_feature.

azul-java-client​

  • Introduced a new Java client with a minimal interface, enabling Java users to interact with Azul via the Rest API.

azul-runner​

  • Git synchronization is now fully managed within azul-runner and no longer handled by a git-sync sidecar.
  • Added a continuously updated liveness check file to detect when the runner stops functioning and reboot a pod.

azul-security​

  • Added new restriction settings for caveats: min_priority and max_priority, limiting which classification caveats can appear with, which prevents invalid classifications.
  • Improved the value displayed by max-security to ensure users know the actual maximum classification.

Demo​

  • Fixed multiple issues affecting broken components.

Retrohunt​

  • Integrated with the Rest API.
  • Now available in the Azul Web UI (under the Binaries dropdown).
  • Fixed numerous bugs related to hunt creation, deletion, and maintenance.

Plugins​

  • jadx

    • New plugin using JADX to decompile .apk and .dex files.
    • Generates features.
    • Decompiles and renders non-core Java libraries for associated binaries (similar to the .NET plugin).

  • image-convert

    • Now converts images to WebP instead of PNG and added support for processing all frames in GIFs.

  • maco

    • Added new features.
    • Replaced yara-python with yara-x.
    • The running maco version is now displayed in configuration information.

  • yara

    • Fixed an issue where events became too large due to the info field storing all features.
    • Now returns rule hits with results.

UI​

  • Added GIF display with step controls (forward and backward navigation).

  • Displays YARA rule hits in the "Data" view.
  • Significantly improved the binary comparison page, including string comparison when exactly two binaries are selected.
  • Fixed an issue where an empty JWT could be sent to the Rest API under certain conditions.
  • Added the ability to request SHA256 downloads from all Azul download plugins.

10.0.0​

Core​

  • Added support for Personal Access Token (PAT) authentication for administrators, enabling easier system-to-system integrations.
  • Added configuration options to control Kafka consumerGroup expiry, allowing users to avoid unnecessary message reprocessing.
  • Updated error message format to include an enum value for clearer and more consistent error identification.
