Module IRIS VT

Introduced in IRIS v1.4.0

This module offers an interface with VirusTotal and IRIS to automatically enrich IOCs with VT insight.
The source code is available here. It is installed by default but needs to be configured to be enabled.

Features

Two types of enrichment mechanism are proposed :

  • Manual : right-click on one or more IOCs and select Get VT insight. This sends the targets IOCs to the module and insights will be fetched and applied.
  • Automatic:
    • On create : This automatically fetch VT insight for newly created IOC
    • On update : This automatically fetch VT insight upon updates of an IOC

The following types of IOCs are handled by the module :

  • ip-*
  • domain
  • hashes of types md5, sha224, sha256, sha512

The insight request on an IOC not handled is simply ignored.

Two types of insights are proposed :

  • tags : This adds a vt:malicious or vt:suspicious tag if the detection thresholds are met (configurable). For domains, an ASN tag can also be added.
  • new attribute : This adds a new attribute to the IOC with the VT insight. It is based on a configurable template.

Configuration

The behavior of the module can be configured as needed. Head to the Advanced > Modules > IrisVT to change it.

  • VT API Key : API key used by the module to connect to VT
  • VT Key is premium : Set to True to indicate the provided API Key is premium.
  • Manual triggers on IOCs : Provides a right-click menu option on IOCs to trigger the VT module on selected elements.
  • Triggers automatically on IOC create: If set to true, the module runs each time an IOC is created. Disabled by default.
  • Triggers automatically on IOC update: If set to true, the module runs each time an IOC is updated. Disabled by default.
  • Assign ASN tag to IP : If set to true, creates a new tag with ASN info on the target IP IOC.
  • IOC tag malicious threshold : Float detection ratio above which the module adds a vt:malicious. To disable, add a value > 100.
  • IOC tag suspicious threshold: Float detection ratio above which the module adds a vt:suspicious. To disable, add a value > 100.
  • Add VT report as new IOC attribute: Creates a new attribute on the IOC, base on the VT report. Templates define on this configuration are used.
  • Domain report template: Jinja2 report template for domain IOCs. Refers to the raw report to assess which fields are available.
  • IP report template: Jinja2 report template for IP IOCs. Refers to the raw report to assess which fields are available.
  • Hash report template: Jinja2 report template for hash IOCs. Refers to the raw report to assess which fields are available.
