* [New/Tuning] Direct Kubelet API Access rules - tuned existing rule for D4C to bump-up severity to high (low FP and very susp behavior) + added 10255 port and wss url. - duplicated same rule logic for auditd/endpoint compatibility for both 10250 port in args and kubeletctl exec. - added a new one using network event vs process argument for more resilience. * ++ * Update discovery_potential_direct_kubelet_access_via_process_args.toml * Update and rename discovery_potential_direct_kubelet_access_via_process_args.toml to lateral_movement_direct_kubelet_access_via_process_args.toml * Update rules/linux/lateral_movement_direct_kubelet_access_via_process_args.toml Co-authored-by: Isai <59296946+imays11@users.noreply.github.com> * Update rules/linux/discovery_potential_kubeletctl_execution.toml Co-authored-by: Isai <59296946+imays11@users.noreply.github.com> * Update discovery_potential_kubeletctl_execution.toml * Update lateral_movement_kubelet_api_connection_attempt_internal_ip.toml * Apply suggestion from @Aegrah Co-authored-by: Ruben Groenewoud <78494512+Aegrah@users.noreply.github.com> * Apply suggestion from @Aegrah Co-authored-by: Ruben Groenewoud <78494512+Aegrah@users.noreply.github.com> --------- Co-authored-by: Isai <59296946+imays11@users.noreply.github.com> 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)
