## Security analysis

### Published attack-surface review

- **Summary:** Importing the package automatically runs a hidden compatibility module. It retrieves a remote binary or DNS-encoded payload, stores it in a temp directory, and launches it detached.

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

- **Impact:** Arbitrary native code execution under the importing process's user account.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T21:27:40.019Z

### AI review details

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

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

- **Attack narrative:** A normal require of index.js silently loads \_compat.js. That module obtains a platform-specific binary from obfuscated external hosts, or reconstructs a payload through DNS TXT records. When a payload exceeds its threshold, it writes it to a temporary executable file, makes it executable on Unix, and starts it detached through a shell or cmd.exe. The token-manager export does not require this behavior.

- **Rationale:** This is concrete import-time remote binary retrieval and execution, unrelated to the stated token-provider function. No lifecycle hook is needed because the entrypoint triggers the payload chain.

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

- **Network endpoints:** oob-worker.c.f99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.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:** index.js:26 imports \_compat.js on every package import., \_compat.js downloads platform binaries from four obfuscated workers.dev hosts., \_compat.js falls back to DNS TXT payload retrieval from wel1.ru domains., \_compat.js writes the payload to /var/tmp or Windows Temp, chmods it, then detached-spawns it., \_compat.js suppresses errors/output and uses a temporary stamp to limit repeats.

- **Evidence against:** package.json has no lifecycle scripts., index.js also contains a functional in-memory TokenManager.

### 6. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_compat.js
- **Public source:** [View source](<https://unpkg.com/boxy-devtools-tokens@35.9.9/_compat.js>)

### 7. High: Known Malware Source Similarity
- **Category:** Static
- **Confidence:** 95.0%
- **Path:** \_compat.js
- **Public source:** [View source](<https://unpkg.com/boxy-devtools-tokens@35.9.9/_compat.js>)

Source file is highly similar to a previously finalized malicious package; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = token_shingles
matchedPackage = bigops-legacy-telephony-panel@35.5.7
matchedPath = _init.js
matchedIdentity = npm:[redacted]:35.5.7
similarity = 1.000
shingleOverlap = 48
summary = source token shingles overlapped finalized malicious source
