T1602 - Data from Configuration Repository

Adversaries may collect data related to managed devices from configuration repositories. Configuration repositories are used by management systems in order to configure, manage, and control data on remote systems. Configuration repositories may also facilitate remote access and administration of devices.

Adversaries may target these repositories in order to collect large quantities of sensitive system administration data. Data from configuration repositories may be exposed by various protocols and software and can store a wide variety of data, much of which may align with adversary Discovery objectives.(Citation: US-CERT-TA18-106A)(Citation: US-CERT TA17-156A SNMP Abuse 2017)

Detection

Identify network traffic sent or received by untrusted hosts or networks that solicits and obtains the configuration information of the queried device.(Citation: Cisco Advisory SNMP v3 Authentication Vulnerabilities)

Shield Active Defense

Decoy Credentials

Create user credentials that are used for active defense purposes.

Seed a target system with credentials (such as username/password, browser tokens, and other forms of authentication data) for the purpose of engagement. Decoy credentials can be planted in many locations and leveraged in a variety of ways.

Opportunity

In order to prolong an adversary engagement operation or enable detections, there is an opportunity to introduce credentials to an adversary that you want them to collect and use.

Use Case

A defender can plant decoy credentials across an array of locations to increase the chances of an adversary finding and using them.

Procedures

Create user credentials for a decoy account, such as ‘User ABC’. Store those credentials in the browser and other places on the system to see if an adversary attempts to harvest them.
