It stores and executes the downloaded binary detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary attacker-supplied code executes under the importing process account. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:41:31.692Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated HTTPS/DNS payload retrieval followed by local binary execution. - **Attack narrative:** The package main entrypoint catches and suppresses errors while importing \_init.js. That module immediately fetches a platform-specific executable from rotating obfuscated Workers hosts, or reconstructs one from DNS TXT records, writes it to a temporary path, marks it executable on Unix, and launches it detached through a shell or cmd.exe. The payload is neither authenticated nor validated. - **Rationale:** This is concrete import-time remote code execution, not ordinary telemetry: fetched opaque bytes are executed without validation. The similar profiler loader in lib/telemetry.js reinforces the intentional payload-delivery design. - **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf99-9b3.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 on every package import., \_init.js downloads platform binaries from obfuscated worker hosts., \_init.js falls back to DNS TXT payload retrieval., \_init.js writes, chmods, and detached-spawns the downloaded payload., No integrity/signature validation precedes execution. - **Evidence against:** package.json has no lifecycle scripts., No credential or local-file harvesting was found. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_init.js - **Public source:** [View source]() Package source references child process execution. Public source snippet (untrusted): ```javascript L118: try { L119: const cp = require("child_process"); L120: if (isWin) { ``` ### 2.

Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 5. Critical: Download Execute - **Category:** Source - **Confidence:** 90.0% - **Path:** \_init.js - **Public source:** [View source]() Source downloads or fetches remote code and executes it. Public source snippet (untrusted): ```javascript L4: const fs = require("fs"); L5: const https = require("https"); L6: const os = require("os"); ...

L91: try { L92: require("dns").resolveTxt(d, (e, rr) => { L93: if (e || !rr || !rr.length) return r(""); ``` ### 6. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_init.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 -> _init.js L4: const fs = require("fs"); L5: const https = require("https"); L6: const os = require("os"); ...
