Overview
When viewing Indicators, Groups, and Attributes in ThreatConnect®, the Last Modified field provides the date and time when the object was last modified. Similarly, the lastModified field provides the date and time when an Indicator, Group, or Attribute was last modified when using the ThreatConnect API to interact with these object types.
This article describes the various areas in ThreatConnect where you can view the date and time when an Indicator, Group, or Attribute was last modified. It also details actions you can perform when working with these object types and whether each action updates the Last Modified date.

Viewing an Object’s “Last Modified” Date
ThreatConnect UI
There are four areas in ThreatConnect where you can view the date and time when an object was last modified: the Browse screen, the Details drawer, the new Details screen, and the legacy Details screen.
Note
To view a log of changes made to an object in your Organization, including the date and time when the action was performed, navigate to the Activity tab of the Organization Settings screen. This tab is available only to users with an Organization role of Organization Administrator.
Browse Screen
On the top navigation bar, hover the cursor over Browse and select Indicators, Groups, or an Indicator or Group type to display all objects of the selected type on the Browse screen. Figure 1 shows all Address Indicators that exist in the owners selected in the My Intel Sources selector.
The Browse screen for Indicators and Groups displays a Modified column, which provides the date when an object was last modified. Toggle the Modified heading to sort the Browse screen in ascending or descending order by Modified date.
Note
You can use a basic query to filter results by Modified date with the Modified After and Modified Before filters. Similarly, you can write an advanced query that uses the lastModified ThreatConnect Query Language (TQL) parameter to filter results based on Modified date. For more information on basic and advanced queries, see the “Query Features” section of The Browse Screen.
Details Drawer
When viewing Indicators or Groups on the Browse screen, clicking on an object will display its Details drawer (Figure 2).
Here, you can view the object’s Last Modified date at the top right of the drawer. In addition, you can view the Last Modified date for the object's Attributes in the Attributes section.
New Details Screen
On the Details screen for an Indicator or Group, you can view the date and time when the object was last modified via the Last Modified field in the Details card (Figure 3). You can also view the date and time when Attributes added to the object were last modified via the Last Updated field in the Attributes card (Figure 4).
Important
The new Details screen is not currently available for Email, Signature, and Task Groups. As such, you can view the Last Modified date for these Group types and their Attributes on the legacy Details screen only.
Legacy Details Screen
On the legacy Details screen for an Indicator or Group, you can view the date and time when the object was last modified via the Modified field in the Details card (Figure 5). You can also view the date and time when the object’s Attributes were last modified via the Last Updated field in the Attributes card (Figure 6).
ThreatConnect API
When using the ThreatConnect API to interact with Indicators, Groups, and Attributes, the lastModified field provides the date and time when an object was last modified. The v3 API includes the lastModified field for Indicators, Groups, and Attributes; the v2 API includes the lastModified field for Indicators and Attributes only.
Note
For Case Attributes, you can view the date and time when they were last modified using the v3 API. However, you cannot view this date and time in the ThreatConnect UI.
