The May 15 IOC expansion added coverage for OpenSearch/Mistral/Guardrails/
UiPath/Squawk-style campaign variants, `opensearch_init.js`, `vite_setup.mjs`,
dead-drop/session protocol strings, and AI-tooling persistence surfaces without
committing full high-entropy indicators that trip secret scanners.
The May 15 node-ipc follow-up blocks `node-ipc@9.1.6`, `9.2.3`, `10.1.1`,
`10.1.2`, `11.0.0`, `11.1.0`, and `12.0.1`, plus the `node-ipc.cjs` payload
hash, malicious tarball hashes, DNS exfil domains, and runtime markers reported
by Socket.
