It uses temporary marker files to suppress repeat execution and DNS as a fallback payload channel. - **Trigger:** Any runtime require/import of index.js, without an explicit setup command. - **Impact:** Arbitrary remote code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:11:14.625Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download/DNS payload retrieval followed by detached execution - **Attack narrative:** Loading index.js catches errors from but still invokes \_adapter.js. The adapter obtains a platform-specific payload from rotating worker hosts or base64 DNS TXT records, writes it to a temporary path, makes it executable on Unix, and launches it detached through a shell or cmd.exe. A marker file delays subsequent execution; the downloaded bytes have no enforced integrity validation. - **Rationale:** This is a concrete import-time remote payload execution chain unrelated to the package's documented menu API. The package is malicious even though it has no npm lifecycle hook. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf99-9b3.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, \*.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 ./\_adapter at module load., \_adapter.js fetches platform binaries from four worker hosts and DNS TXT resolvers., \_adapter.js writes payloads to /var/tmp or TEMP, chmods them, then detached-spawns them., No checksum is actually verified despite the integrity-check comment. - **Evidence against:** package.json has no lifecycle scripts., No credential or local-file harvesting was found in the entrypoint chain. ## Public findings ### 1.
