## Security analysis

### Published attack-surface review

- **Summary:** Importing the package triggers a hidden downloader and detached execution chain. It obtains platform-specific content over HTTPS or DNS, drops it into a temp directory, and runs it.

- **Trigger:** Any require/import of index.js

- **Impact:** Arbitrary native code execution as the importing process user.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-03T08:48:33.313Z

### AI review details

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

- **Mechanism:** remote binary download, temp-file drop, and detached execution

- **Attack narrative:** The main entrypoint silently requires setup.js. At import time, setup.js selects a platform-specific payload path, downloads a binary from concealed workers.dev hosts or reconstructs one from DNS TXT records, writes it to a temporary path, makes it executable on Unix, and starts it detached through /bin/sh or cmd.exe. The timestamp file only rate-limits repeats; it does not provide consent or validation.

- **Rationale:** This is a concrete import-time remote payload execution chain unrelated to the declared popup module. Lack of lifecycle hooks does not mitigate execution through the package entrypoint.

- **Files touched:** index.js, setup.js, /tmp/.analytics\_state, /var/tmp/.cache\_\<random\>

- **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.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.js on every package import., setup.js fetches platform binaries from three workers.dev hosts., setup.js can retrieve base64 binary content via DNS TXT records., setup.js writes the download to /var/tmp or Windows Temp and chmods it., setup.js launches the downloaded file detached via shell/cmd., No consent, integrity verification, or user command gates execution.

- **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint.
