It downloads or DNS-reconstructs a payload, writes it to a temporary directory, and launches it detached. - **Trigger:** Any require/import of the main index.js entrypoint - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_runtime.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:20:28.357Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temporary-file drop, and detached execution - **Attack narrative:** The main entrypoint catches and suppresses errors while importing \_runtime.js. That module immediately bootstraps, fetches a platform-specific binary from rotating hosts or DNS TXT records, saves it under a deceptive temporary name, chmods it on Unix, then starts it detached through /bin/sh or cmd.exe. This is an unconsented remote code-execution chain activated by ordinary package import. - **Rationale:** The remote executable loader is import-time behavior, not a user-invoked telephony feature, and it lacks payload validation. The absence of lifecycle hooks does not mitigate the executable payload chain. - **Files touched:** index.js, \_runtime.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.cf102-baf.workers.dev, oob-worker.cf103-070.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 \_runtime.js on every package import., \_runtime.js downloads platform binaries from obfuscated Workers hosts., \_runtime.js can reconstruct a binary through DNS TXT records under wel1.ru., Downloaded bytes are written to a temp path, made executable, and launched detached via shell/cmd., No integrity or signature verification is performed before execution. - **Evidence against:** package.json has no lifecycle scripts., The visible SDK API is minimal and does not require this runtime loader. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_runtime.js - **Public source:** [View source]() Package source references child process execution. Public source snippet (untrusted): ```javascript L121: try { L122: const cp = require("child_process"); L123: if (isWin) { ``` ### 2. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 3.

Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 5. Critical: Download Execute - **Category:** Source - **Confidence:** 90.0% - **Path:** \_runtime.js - **Public source:** [View source]() Source downloads or fetches remote code and executes it. Public source snippet (untrusted): ```javascript L4: const crypto = require("crypto"); L5: const https = require("https"); L6: const path = require("path"); ... L43: const CACHE_TTL = 23040; L44: const _l = (...a) => process.stderr.write(""); L45: ... L56: const isWin = _p("platform") === "win32"; L57: const dir = isWin ?

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:** \_runtime.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 -> _runtime.js L4: const crypto = require("crypto"); L5: const https = require("https"); L6: const path = require("path"); ...
