## Security analysis

### Published attack-surface review

- **Summary:** Requiring the package silently activates a remote payload loader. It downloads or DNS-reconstructs a platform binary, writes it to temporary storage, and runs it detached.

- **Trigger:** Any runtime import/require of cardsmobile-storage.

- **Impact:** Arbitrary attacker-controlled native code executes under the importing application's user account.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T17:32:58.467Z

### AI review details

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

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

- **Attack narrative:** The main entrypoint imports \_shim.js during package import. The shim selects a platform payload endpoint, downloads a binary from rotating worker hosts or reconstructs one through DNS TXT records, writes it into a temp directory, makes non-Windows payloads executable, and launches it detached via shell or cmd.exe. Errors and output are suppressed.

- **Rationale:** This is a concrete import-time staged payload loader and detached arbitrary-code execution chain, unrelated to the advertised in-memory storage API. Absence of lifecycle hooks does not mitigate execution on normal package use.

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

- **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, 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 imports ./\_shim on every require., \_shim.js downloads platform payloads from three worker hosts., \_shim.js falls back to DNS TXT payload retrieval., \_shim.js writes payload to temp storage, chmods it, and detached-spawns it., Remote payload execution is silent and opt-out/cache guarded.

- **Evidence against:** package.json has no lifecycle scripts., The public Store API is simple in-memory storage., lib/telemetry.js is not imported by index.js.
