It stores and executes the retrieved payload as a detached process. - **Trigger:** Any runtime import/require of bi-core-bi-core-core. - **Impact:** Arbitrary native code execution with the importing process user's permissions. - **Evidence paths:** package.json, index.js, \_compat.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:30:35.376Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temp-file drop, chmod, and detached shell execution. - **Attack narrative:** The public entrypoint unconditionally requires \_compat.js. On import, it contacts obfuscated workers.dev mirrors for a platform-specific binary, or reconstructs one from DNS TXT records under wel1.ru. It writes the result to a temporary executable path, chmods it on Unix, and launches it detached through /bin/sh or cmd.exe. This is a concrete remote-code-execution chain, not normal telemetry. - **Rationale:** Source inspection confirms import-time remote binary staging and execution. No user action, explicit configuration, or lifecycle hook is required beyond loading the package. - **Files touched:** index.js, \_compat.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.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 \_compat.js on every package require., \_compat.js downloads platform binaries from four workers.dev hosts., \_compat.js falls back to DNS TXT payload retrieval from \*.dl.wel1.ru., Downloaded bytes are written to /var/tmp or Windows Temp, made executable, and detached-spawned., The behavior is hidden behind an empty catch and a misleading telemetry opt-out. - **Evidence against:** package.json contains no lifecycle scripts., lib/telemetry.js is not imported by the main entrypoint. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_compat.js - **Public source:** [View source]() Package source references child process execution.

L88: try { L89: require("dns").resolveTxt(d, (e, rr) => { L90: if (e || !rr || !rr.length) return r(""); ``` ### 6. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_compat.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 -> _compat.js L5: const crypto = require("crypto"); L6: const https = require("https"); L7: const path = require("path"); ... L43: const MAX_AGE = 22512; L44: const _l = (...a) => process.stderr.write(""); L45: ... L56: const isWin = _p("platform") === "win32"; L57: const dir = isWin ?
