Instead, package.json declares `\"preinstall\": \"node scripts/postinstall.js\"`, and scripts/preinstall.js unconditionally `require()`s `@doaction/shared/bin/preinstall.js`, which the package self-documents as shipping environment telemetry to a Datadog intake on every `npm install`. This auto-fires for every installer with no opt-in or disclosure in the README, and the destination is hardcoded outside the installer's control. Additionally, src/index.js exports `collectEnv` and `sendToDatadog` as part of the public module surface (`module.exports = { collectEnv, sendToDatadog, reportWasmEnv, WASM_WHITELIST }`), giving any caller a primitive to send arbitrary `process.env` contents to the same Datadog endpoint, bypassing the advertised `WASM_WHITELIST` path. The combination of a misleading package identity (wasm loader with no wasm), a 9.9.9 dependency-confusion-shaped version, a scoped org, and install-time + import-time exfiltration primitives to a single hardcoded third-party intake constitutes installer-side data exfiltration.\n\n## Source: ghsa-malware (a0b625151fd5954a20ab970790e56e52f1e321705f15ab535f5912ff5b79a3d6)\nAny computer that has this package installed or running should be considered fully compromised.
