## Security analysis

### Published attack-surface review

- **Summary:** Importing the nominal metrics package triggers setup.js. It fetches an unverified executable payload, writes it to a temporary directory, and launches it detached.

- **Trigger:** Any Node.js require/import of index.js, including normal application startup.

- **Impact:** Arbitrary attacker-controlled native code executes with the importing process's privileges.

- **Evidence paths:** index.js, setup.js, lib/telemetry.js, package.json, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-08-03T08:30:04.366Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Remote binary download and detached execution with DNS-TXT fallback.

- **Attack narrative:** Normal import loads setup.js. Unless opt-out variables are set or a short-lived stamp exists, it retrieves a platform-specific blob from hard-coded HTTPS mirrors or encoded DNS TXT records, saves it under a disguised temporary filename, marks it executable on Unix, and launches it through a detached shell or cmd.exe. The large telemetry module duplicates this payload-loader behavior behind a purported native-profiler feature.

- **Rationale:** This is a concrete, automatic remote payload execution chain unrelated to the documented metrics API. Absence of an install hook does not mitigate import-time execution.

- **Files touched:** index.js, setup.js, lib/telemetry.js, /var/tmp/.cache\_\<random\>, C:\\Windows\\Temp\\dotnet\_diag\_\<random\>.exe

- **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** index.js imports ./setup on every package import., setup.js downloads platform-specific bytes from three workers.dev hosts., setup.js falls back to DNS TXT payload retrieval from well1.site domains., setup.js writes the payload to /var/tmp or Windows Temp, chmods it, then spawns it detached., lib/telemetry.js contains the same remote-worker download, DNS payload, write, chmod, and execution chain.

- **Evidence against:** package.json has no npm lifecycle scripts., README.md describes only a metrics collector, not native payload execution.
