An explicit CLI setup modifies a Chrome extension to start an offscreen ZeroGPU runtime automatically. A ZeroGPU WebSocket can supply task tracking URLs that trigger remote tag execution or credentialed beacons. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-13T01:00:46.563Z - **Finished:** 2026-08-13T01:02:17.011Z - **Download time:** 1013 ms - **Static scan time:** 2936 ms - **AI review time:** 86499 ms - **Total time:** 90448 ms ## Security analysis ### Published attack-surface review - **Summary:** An explicit CLI setup modifies a Chrome extension to start an offscreen ZeroGPU runtime automatically. A ZeroGPU WebSocket can supply task tracking URLs that trigger remote tag execution or credentialed beacons. - **Trigger:** User runs \`npx zerogpu init\`, then the integrated extension loads and receives a task. - **Impact:** Broad extension permissions and third-party tracking requests may expose browsing identity/cookies to URLs supplied by the service. - **Evidence paths:** package.json, bin/zerogpu.mjs, dist/extension/zerogpu-offscreen.js - **Review source:** ai\_review - **Reviewed:** 2026-08-13T01:02:17.011Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** extension manifest scaffolding plus server-driven tracking requests - **Rationale:** This is not confirmed malware because setup is explicit and no install hook or stealthy package-side persistence exists. It warrants warning for broad extension lifecycle changes and server-directed credentialed tracking. - **Files touched:** bin/zerogpu.mjs, dist/extension/zerogpu-offscreen.js - **Network endpoints:** https://devices.zerogpu.ai, https://zerogpu-browser-sdk.pages.dev/tag-runner.html ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Explicit \`init\` patches an extension manifest with \`\\`, offscreen/storage, and CSP., Runtime accepts WebSocket task requests and fires supplied tracking URLs., Tracking fallback sends credentialed cross-origin requests; hosted runner executes tracking scripts., Runtime collects device identity/fingerprint context; optional location/camera are configuration-gated. - **Evidence against:** No preinstall/install/postinstall hook; only a prepublish build hook exists., Manifest mutation requires an explicit CLI \`init\` command., Network registration is to the package-aligned ZeroGPU endpoint and requires an operator key., Camera and location telemetry default to false. ## Public findings ### 1.
