An explicitly initialized Chrome extension can persistently start an offscreen device-runtime that registers detailed device data and accepts a server-provided WebSocket endpoint. No unconsented npm install-time execution or foreign AI-agent control-surface mutation was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-04T01:36:20.244Z - **Finished:** 2026-08-04T01:36:58.998Z - **Download time:** 1518 ms - **Static scan time:** 1704 ms - **AI review time:** 35530 ms - **Total time:** 38754 ms ## Security analysis ### Published attack-surface review - **Summary:** An explicitly initialized Chrome extension can persistently start an offscreen device-runtime that registers detailed device data and accepts a server-provided WebSocket endpoint. No unconsented npm install-time execution or foreign AI-agent control-surface mutation was found. - **Trigger:** User runs zerogpu init or host extension invokes initZeroGpuOffscreen with an operator key, then Chrome starts the extension. - **Impact:** The configured extension may disclose extensive device/context metadata to its orchestrator and persist startup behavior in the host extension. - **Evidence paths:** package.json, bin/zerogpu.mjs, dist/extension/zerogpu-offscreen.js, dist/assets/zerogpu-assets.json, dist/assets/transformers.min.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T01:36:58.998Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Extension scaffolding, device registration telemetry, model-runtime loading, and WebSocket orchestration. - **Rationale:** The package is not malicious by the install-time boundary, but its explicit integration command changes a browser extension's startup and permission configuration while runtime transmits detailed device data. This is a concrete, user-invoked extension lifecycle capability appropriate for a warning. - **Files touched:** bin/zerogpu.mjs, dist/extension/zerogpu-offscreen.js, dist/assets/transformers.min.js, dist/assets/wllama/index.js, dist/assets/ort-wasm-threaded.wasm - **Network endpoints:** https://devices.zerogpu.ai/register, https://\*.zerogpu.ai/\*, https://huggingface.co/\*, https://\*.hf.co/\*, https://cdn-lfs.huggingface.co/\*, https://cdn-lfs-us-1.huggingface.co/\* ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** dist/extension/zerogpu-offscreen.js collects Telegram identity, page URL/referrer, UA, hardware, WebGL renderer, battery, and network data for registration., bin/zerogpu.mjs init explicitly writes a target extension manifest, adds optional broad model hosts/CSP, and scaffolds startup offscreen code., The scaffold starts the offscreen SDK on Chrome install/update and browser startup., Runtime POSTs registration data to devices.zerogpu.ai and connects to a server-provided WebSocket URL. - **Evidence against:** package.json has only prepublishOnly; no install-time lifecycle hook., Filesystem and manifest changes occur only under explicit zerogpu init/vendor commands., Camera and geolocation collection are disabled by default; camera preview is stripped before registration., Dynamic imports in the offscreen entry load vendored local model runtimes; no shell/process execution was found. ## Public findings ### 1.
