Security researchers use AlloyProxy15 to simulate attacks from diverse origins. Data scientists use it to scrape e‑commerce sites without triggering rate limits. Unfortunately, its popularity also attracted reverse engineers, license crackers, and malware authors. alloyproxy15 patched

The maintainers added the #[serde(deny_unknown_fields)] attribute to all external-facing structs. If an attacker sends a MessagePack payload with extra fields (e.g., exec_hook), the deserializer immediately returns an InvalidData error, preventing any memory corruption.
