What it detects

This rule detects Python decoding and executing a base64-encoded payload inline, an execution technique used in the TeamPCP multi-stage supply chain attack on security infrastructure. Combining base64 decoding with dynamic exec obscures the executed code and is characteristic of staged malicious payloads rather than normal application behavior.
