## Security analysis

### Published attack-surface review

- **Summary:** Importing the package triggers a hidden remote payload downloader. It executes the downloaded platform binary detached from a temporary directory.

- **Trigger:** Any runtime require/import of bigops-timeline.

- **Impact:** Arbitrary attacker-controlled native code execution in the importing user's environment.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T18:20:32.823Z

### AI review details

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

- **Mechanism:** Remote binary download via HTTPS/DNS followed by detached execution.

- **Attack narrative:** At package import, index.js silently loads \_helpers.js. That module fetches a platform-specific binary from obfuscated worker hosts, falling back to DNS TXT records that reconstruct base64 payload bytes. It writes the payload to a temp path, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. Failures are suppressed, obscuring the behavior.

- **Rationale:** This is concrete import-time remote payload execution, unrelated to the declared timeline API. The unused telemetry module contains a parallel downloader/executor implementation, reinforcing intentional malicious capability.

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

- **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf100-416.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 \_helpers.js on every package import., \_helpers.js downloads platform binaries over HTTPS and DNS TXT fallback., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, then spawned detached., Hosts and DNS domains are obfuscated by string joining., Telemetry opt-out variables merely gate the payload fetch.

- **Evidence against:** package.json has no lifecycle scripts., No credential or project-file harvesting was found in the import path.
