T1584 Compromise Infrastructure

Adversaries may compromise third-party infrastructure that can be used during targeting. Infrastructure solutions include physical or cloud servers, domains, and third-party web and DNS services. Instead of buying, leasing, or renting infrastructure an adversary may compromise infrastructure and use it during other phases of the adversary lifecycle.⁵³⁶¹⁰ Additionally, adversaries may compromise numerous machines to form a botnet they can leverage.

Use of compromised infrastructure allows adversaries to stage, launch, and execute operations. Compromised infrastructure can help adversary operations blend in with traffic that is seen as normal, such as contact with high reputation or trusted sites. For example, adversaries may leverage compromised infrastructure (potentially also in conjunction with Digital Certificates) to further blend in and support staged information gathering and/or Phishing campaigns.² Additionally, adversaries may also compromise infrastructure to support Proxy.¹

By using compromised infrastructure, adversaries may make it difficult to tie their actions back to them. Prior to targeting, adversaries may compromise the infrastructure of other adversaries.⁷
