Ray raylet/gcs_server spawning shell or calculator (CVE-2025-62593)
Detects a Ray raylet, gcs_server, or dashboard process spawning a calculator process (a near-certain PoC/exploit indicator) or a shell child process carrying suspicious network, encoding, or reverse-shell command-line indicators, consistent with post-exploitation of CVE-2025-62593. Known-legitimate pipeline package-install commands are filtered out to reduce noise from normal Ray job workers.
