Business Relationships

Parent: T1591

Description

Adversaries may gather information about the victim's business relationships that can be used during targeting. Information about an organization’s business relationships may include a variety of details, including second or third-party organizations/domains (ex: managed service providers, contractors, etc.) that have connected (and potentially elevated) network access. This information may also reveal supply chains and shipment paths for the victim’s hardware and software resources. Adversaries may gather this information in various ways, such as direct elicitation via [Phishing for Information](https://attack.mitre.org/techniques/T1598). Information about business relationships may also be exposed to adversaries via online or other accessible data sets (ex: [Social Media](https://attack.mitre.org/techniques/T1593/001) or [Search Victim-Owned Websites](https://attack.mitre.org/techniques/T1594)).(Citation: ThreatPost Broadvoice Leak) Gathering this information may reveal opportunities for other forms of reconnaissance (ex: [Phishing for Information](https://attack.mitre.org/techniques/T1598) or [Search Open Websites/Domains](https://attack.mitre.org/techniques/T1593)), establishing operational resources (ex: [Establish Accounts](https://attack.mitre.org/techniques/T1585) or [Compromise Accounts](https://attack.mitre.org/techniques/T1586)), and/or initial access (ex: [Supply Chain Compromise](https://attack.mitre.org/techniques/T1195), [Drive-by Compromise](https://attack.mitre.org/techniques/T1189), or [Trusted Relationship](https://attack.mitre.org/techniques/T1199)).

Mapped SPARTA techniques

  • Launch information centres on launch-provider relationships (rideshare manifests, launch-vehicle integration, range services) — these are exactly the business relationships T1591.002 covers; SPARTA REC-0004's primary intelligence target is the customer-launcher contractual ecosystem.

  • Supply-chain reconnaissance is fundamentally about identifying second/third-party suppliers, integrators, and contractors; T1591.002 'Business Relationships' is the ATT&CK sub-technique that directly addresses business-relationship intelligence collection.
