## Verdict summary
**Blocked & quarantined** — Unconsented arbitrary native code execution under the importing process user.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Block by default
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 35.4.5
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

The package's documented auth API is unrelated to its import-time remote binary loader. No lifecycle script is needed because ordinary package import triggers the execution chain.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Malicious
- **Recorded analysis confidence:** 99.0%
- **Started:** 2026-08-05T15:27:01.672Z
- **Finished:** 2026-08-05T15:27:29.145Z

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Importing the advertised package silently fetches a platform-specific executable payload and runs it detached. It uses a temporary marker to limit repeat execution.

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

- **Impact:** Unconsented arbitrary native code execution under the importing process user.

- **Evidence paths:** package.json, index.js, \_helpers.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T15:27:29.145Z

### AI review details

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

- **Mechanism:** remote payload download, disk drop, and detached execution

- **Attack narrative:** Loading index.js imports \_helpers.js, which invokes start() without user action. It downloads a platform-specific binary from rotating workers.dev hosts, with DNS TXT payload retrieval as fallback; it writes the bytes to a temporary executable, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe.

- **Rationale:** The package's documented auth API is unrelated to its import-time remote binary loader. No lifecycle script is needed because ordinary package import triggers the execution chain.

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

- **Network endpoints:** oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** index.js imports \_helpers.js at package load., \_helpers.js immediately calls start() on import., \_helpers.js downloads platform binaries from four workers.dev hosts., DNS TXT fallback retrieves base64 payloads from \*.dl.wel1.ru., Downloaded payload is written, chmodded, and detached-spawned via shell/cmd.

- **Evidence against:** package.json has no lifecycle scripts., TokenManager itself is a small in-memory token store.

## Affected versions and remediation

This report applies to devplatform-spa-plugin-auth@35.4.5.
