## Verdict summary
**Blocked & quarantined** — Unconsented remote code execution as 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:** 20.8.7
- **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.

This is a concrete import-time staged-payload and remote-execution chain unrelated to the declared UI toolkit. The absence of lifecycle hooks does not mitigate execution through the normal package entrypoint.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Malicious
- **Recorded analysis confidence:** 99.0%
- **Started:** 2026-08-02T14:25:38.461Z
- **Finished:** 2026-08-02T14:26:31.734Z
- **Download time:** 508 ms
- **Static scan time:** 64 ms
- **AI review time:** 52700 ms
- **Total time:** 53273 ms

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 package immediately loads \_shim.js. The shim fetches a platform-specific binary, including through DNS TXT fallback, then executes it detached.

- **Trigger:** Runtime require/import of the main index.js entrypoint.

- **Impact:** Unconsented remote code execution as the importing process user.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-02T14:26:31.734Z

### AI review details

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

- **Mechanism:** Remote binary download, temp-file staging, and detached execution.

- **Attack narrative:** The main entrypoint silently requires \_shim.js. On import, it avoids opt-out environments, creates a marker, downloads a platform-specific payload from obfuscated endpoints or reconstructs it from DNS TXT records, writes it to temporary storage, marks Unix payloads executable, and launches it through a detached shell or cmd.exe process.

- **Rationale:** This is a concrete import-time staged-payload and remote-execution chain unrelated to the declared UI toolkit. The absence of lifecycle hooks does not mitigate execution through the normal package entrypoint.

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

- **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.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 block:** index.js imports \_shim.js on every package import., \_shim.js downloads binaries from obfuscated workers.dev hosts., \_shim.js falls back to DNS TXT payload delivery., \_shim.js writes payloads to temp storage, chmods them, and detached-spawns them.

- **Evidence against:** package.json contains no lifecycle scripts., No credential harvesting or AI-agent control-surface writes found.

## Affected versions and remediation

This report applies to tui-react-mobile-styles@20.8.7.

- Avoid installing tui-react-mobile-styles@20.8.7. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
