Detects the execution of the 'sckit' Go implant, a malicious binary associated with trojanized '@memtensor/memos-cloud-openclaw-plugin' or 'MemoryOS' packages. The rule identifies instances where this binary is spawned as a child process of a language runtime (Node.js or Python) when the execution originates from specific directory paths associated with these packages, or when the parent process command line indicates these packages are being initialized.

Detects when a namespace-scoped identity creates, updates, or patches AWS or Azure IAM-related custom resources in Kubernetes. This pattern monitors for a 'confused deputy' scenario where a user might attempt to leverage high-privilege cloud operators (like ACK or ASO v2) that operate with a shared high-privilege identity to modify cloud IAM configurations.
