TA0042 · RESOURCE DEVELOPMENT
Compromise Infrastructure
Adversaries may compromise third-party infrastructure that can be used during targeting. Infrastructure solutions include physical or cloud servers, domains, network devices, and third-party web and DNS services.
Detect it with
Consider monitoring for anomalous changes to domain registrant information and/or domain resolution information that may indicate the compromise of a domain.
Why it matters on shift
Compromise Infrastructure is one of the concrete ways adversaries achieve resource development. Recognising it in telemetry lets you name the technique in your ticket and pivot to what came before and after.
What to look for next
After resource development, the next tactic is usually Initial Access. Search your telemetry for the transition before closing the ticket.
8 sub-techniques
How it shows up in practice
- T1584.001
Domains
Adversaries may hijack domains and/or subdomains that can be used during targeting. Domain registration hijacking is the act of changing the registration of a domain name without the permission of the original registrant.
- T1584.002
DNS Server
Adversaries may compromise third-party DNS servers that can be used during targeting. During post-compromise activity, adversaries may utilize DNS traffic for various tasks, including for Command and Control (ex: Application Layer Protocol).
- T1584.003
Virtual Private Server
Adversaries may compromise third-party Virtual Private Servers (VPSs) that can be used during targeting. There exist a variety of cloud service providers that will sell virtual machines/containers as a service.
- T1584.004
Server
Adversaries may compromise third-party servers that can be used during targeting. Use of servers allows an adversary to stage, launch, and execute an operation.
- T1584.005
Botnet
Adversaries may compromise numerous third-party systems to form a botnet that can be used during targeting. A botnet is a network of compromised systems that can be instructed to perform coordinated tasks.
- T1584.006
Web Services
Adversaries may compromise access to third-party web services that can be used during targeting. A variety of popular websites exist for legitimate users to register for web-based services, such as GitHub, Twitter, Dropbox, Google, SendGrid, etc.
- T1584.007
Serverless
Adversaries may compromise serverless cloud infrastructure, such as Cloudflare Workers, AWS Lambda functions, or Google Apps Scripts, that can be used during targeting.
- T1584.008
Network Devices
Adversaries may compromise third-party network devices that can be used during targeting.
