This rule detects activities associated with c-ares TCP Use-After-Free (UAF) exploitation, specifically identifying execution of known Proof-of-Concept binaries, the creation of exploitation proof marker files, and suspicious parent-child process relationships where network-facing services or common interpreters (e.g., node, curl, python) spawn unexpected calculator or shell processes indicative of RCE payloads.
