* [New Rules] AWS IAM new identity federation provider rules AWS IAM SAML Provider Created and AWS IAM OIDC Provider Created by Rare User detect the creation of new identity federation providers in AWS IAM. SAML and OIDC providers establish trust relationships with external identity providers, enabling federated access to AWS resources. Adversaries who gain administrative access may create rogue providers to establish persistent access that survives credential rotation, allowing them to assume roles using tokens from an IdP they control. These rules map to MITRE ATT&CK T1484.002 (Trust Modification), which is referenced in the CISA Scattered Spider advisory (AA23-320A) under the Privilege Escalation tactic. Existing Related Coverage: We already detect `UpdateSAMLProvider` via privilege_escalation_iam_saml_provider_updated.toml. These new rules close the gap by detecting the creation of federation providers, the initial step required to establish rogue trust relationships. * Update rules/integrations/aws/persistence_iam_oidc_provider_created.toml Co-authored-by: Ruben Groenewoud <78494512+Aegrah@users.noreply.github.com> * Update rules/integrations/aws/persistence_iam_oidc_provider_created.toml Co-authored-by: Ruben Groenewoud <78494512+Aegrah@users.noreply.github.com> * Apply suggestion from @imays11 --------- Co-authored-by: Ruben Groenewoud <78494512+Aegrah@users.noreply.github.com>
rules/
Rules within this folder are organized by solution or platform. The structure is flattened out, because nested file hierarchies are hard to navigate and find what you're looking for. Each directory contains several .toml files, and the primary ATT&CK tactic is included in the file name when it's relevant (i.e. windows/execution_via_compiled_html_file.toml)
