* [New] AWS Rare Source AS Organization Activity Surfaces an AWS identity whose successful API traffic is dominated by a small set of large cloud-provider source AS organization labels, yet also shows a very small share of traffic from other AS organization names—including at least one sensitive control-plane, credential, storage, or model-invocation action on that uncommon network path with recent activity from the uncommon path. The intent is to highlight disproportionate “baseline” cloud egress versus sparse use from rarer networks on the same principal, a shape that can appear when automation or CI credentials are reused or pivoted outside their usual hosted-cloud footprint. * Apply suggestion from @eric-forte-elastic Co-authored-by: Eric Forte <119343520+eric-forte-elastic@users.noreply.github.com> * Update initial_access_aws_api_unusual_asn.toml * Update initial_access_aws_api_unusual_asn.toml * Update initial_access_aws_api_unusual_asn.toml --------- Co-authored-by: Eric Forte <119343520+eric-forte-elastic@users.noreply.github.com> Co-authored-by: Mika Ayenson, PhD <Mikaayenson@users.noreply.github.com> Co-authored-by: shashank-elastic <91139415+shashank-elastic@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)
