admin or user activity are expected to generate some false positives	t1546 t1546.004 linux sigma
application teams and infrastructure-as-code pipelines routinely create event source mappings to wire data pipelines, queue consumers, and stream processors to lambda functions. verify whether the principal in `aws.cloudtrail.user_identity.arn`, the function, and the event source are expected for the workload. known deployment roles and automation can be excluded after validation.	t1546 t1578 T1648 aws elastic
changes to the shell profile tend to be noisy, a tuning per your environment will be required.	t1546 cross-platform elastic
cluster operators and gitops automation may legitimately install or upgrade admission controllers (e.g. cert-manager, gatekeeper, kyverno, service mesh components). validate change tickets and approved controllers before tuning.	t1546 T1562 kubernetes elastic
cross-account invoke permissions are used for legitimate multi-account architectures and partner integrations. verify the granted account in `aws.cloudtrail.request_parameters`, the function, and the `principal` value in `aws.cloudtrail.request_parameters` against approved cross-account access. known partner or internal account ids can be excluded after validation. this rule cannot distinguish a grant to the function's own account from an external account, so same-account resource-policy grants (uncommon, since same-account invocation normally uses iam identity-based policies) will also alert.	t1546 t1578 aws elastic
custom windows error reporting debugger or applications restarted by werfault after a crash.	t1036 t1546 windows elastic
dell computers on some versions register an event consumer that is known to cause false positives when brightness is changed by the corresponding keyboard button	t1546 t1546.003 windows sigma

gitops and platform controllers (cert-manager, gatekeeper, kyverno, service mesh) legitimately manage webhooks. validate change tickets and controller identities before tuning.	t1546 T1562 gcp elastic

legitimate applications registering their binary from on of the suspicious locations mentioned above (tune it)	t1546 t1546.012 windows sigma
legitimate ci/cd automation that requires workflow file modifications may trigger this alert if not properly configured with the necessary permissions. review the workflow configuration and ensure the github_token or pat has the required 'workflows' permission if the modification is intentional.	t1059 t1195 t1546 github elastic

legitimate setup scripts may reference metadata endpoints or download tooling. review the decoded script in \"esql_priv.aws_cloudtrail_lifecycle_script\", verify the principal in \"aws.cloudtrail.user_identity.arn\", and confirm the activity is approved. note this rule only matches unobfuscated patterns; a clean result does not guarantee a benign script.	t1059 t1546 aws elastic

maybe some system utilities in rare cases use linking keys for backward compatibility	t1546 t1546.015 windows sigma
some organizations may legitimately expose lambda functions for cross-account or anonymous invocation (e.g., custom public apis, integrations, or legacy architectures). validate whether the function owner explicitly intended to make the function publicly invokable. routine ci/cd deployments or iac templates may also temporarily set permissive policies; confirm this is expected behavior before treating it as suspicious.	t1546 t1578 aws elastic
