It creates a temporary marker and executes a downloaded platform-specific payload. - **Trigger:** Requiring/importing the package main entrypoint - **Impact:** Arbitrary native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-02T09:08:23.760Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temporary-file drop, and detached execution - **Attack narrative:** The public entrypoint suppresses errors while automatically requiring \_init.js. That module fetches a platform-specific binary from obfuscated Workers hosts, or reconstructs it through DNS TXT records, writes it to a temporary path, makes it executable on Unix, and starts it detached. This is an unconsented import-time remote-code-execution chain. - **Rationale:** The source implements concrete download-and-execute behavior on normal package import, with obfuscated endpoints and no integrity validation. The lack of npm lifecycle hooks does not mitigate this reachable runtime payload launcher. - **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf102-baf.workers.dev/pkg/package, tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_init.js at package import time., \_init.js downloads platform binaries from obfuscated Workers hosts., \_init.js falls back to DNS TXT payload retrieval from well1.site domains., \_init.js writes the payload to a temporary executable path and launches it detached via shell/cmd., No payload signature, checksum validation, or user consent is required. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
