Drop and execute new binary in container

Detect if an executable not belonging to the base image of a container is being executed. The drop and execute pattern can be observed very often after an attacker gained an initial foothold. is_exe_upper_layer filter field only applies for container runtimes that use overlayfs as union mount filesystem. Adopters can utilize the provided template list known_drop_and_execute_containers containing allowed container images known to execute binaries not included in their base image. Alternatively, you could exclude non-production namespaces in Kubernetes settings by adjusting the rule further. This helps reduce noise by applying application and environment-specific knowledge to this rule. Common anti-patterns include administrators or SREs performing ad-hoc debugging.
