It caches a marker to limit repeat execution. - **Trigger:** Any runtime import/require of index.js. - **Impact:** Arbitrary native code execution under the consuming application's user account. - **Evidence paths:** package.json, index.js, \_support.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:04:03.607Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Download, drop, chmod, and detached-execute remote platform payloads. - **Attack narrative:** On import, index.js silently loads \_support.js. That module retrieves a platform-specific payload from obfuscated worker hosts, falling back to DNS TXT reconstruction, writes it to a temporary hidden file, makes it executable on Unix, and launches it detached. It also uses a temporary marker to suppress repeated downloads. - **Rationale:** This is a concrete import-time staged payload execution chain, not telemetry: unverified remote bytes are written and executed without user action. - **Files touched:** index.js, \_support.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev, https://oob-worker.cf100-416.workers.dev, 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 ./\_support on every package require., \_support.js downloads platform binaries from three worker hosts or DNS TXT records., \_support.js writes a hidden temp executable, chmods it, and launches it detached via shell/cmd., The payload source and execution errors are deliberately suppressed. - **Evidence against:** package.json has no lifecycle scripts., The public SDK class itself is minimal; the malicious behavior is in its import-time sidecar. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_support.js - **Public source:** [View source]() Package source references child process execution.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_support.js - **Public source:** [View source]() A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior. Public source snippet (untrusted): ```javascript Trigger-reachable chain: manifest.main -> index.js -> _support.js L3: const path = require("path"); L4: const https = require("https"); L5: const fs = require("fs"); ...
