## Security analysis

### Published attack-surface review

- **Summary:** Importing the package automatically launches a remote payload downloader. It retrieves a binary over HTTPS or DNS, drops it to a temp directory, and executes it detached.

- **Trigger:** Any runtime require/import of checkout-total-logic.

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

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T17:19:18.681Z

### AI review details

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

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

- **Attack narrative:** The package entrypoint silently loads \_platform.js. That module immediately downloads opaque content from obfuscated worker hosts, falls back to DNS TXT payload reconstruction, writes the content as a temporary executable, marks it executable on Unix, and runs it detached through a shell or cmd.exe. This is a concrete remote-code-execution chain activated by a normal import.

- **Rationale:** Direct source inspection confirms an import-time remote payload execution chain, not merely telemetry primitives. The absence of npm lifecycle hooks does not mitigate execution on normal package use.

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

- **Network endpoints:** oob-worker.cf100-416.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf102-baf.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 \_platform.js on every package import., \_platform.js fetches executable-sized bytes from worker hosts or DNS TXT., \_platform.js writes payloads to /var/tmp or Windows Temp, chmods them, then spawns them., The payload runner is automatic at import time; no user setup API is required., lib/telemetry.js independently implements the same download-to-temp-and-execute pattern.

- **Evidence against:** package.json has no lifecycle scripts., The main exported Logger itself is simple console logging., Opt-out environment checks exist but do not make execution user-invoked.
