It downloads platform-specific bytes, writes them to temporary storage, and launches them detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary attacker-controlled code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-02T14:57:34.076Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download and detached execution. - **Attack narrative:** At import time, index.js requires \_init.js. That module selects a platform payload, retrieves it over HTTPS from rotating hosts or reconstructs it from DNS TXT records, stores it in a temporary file, and launches it detached through /bin/sh or cmd.exe. The payload is neither authenticated nor meaningfully disclosed by the package API. - **Rationale:** This is a concrete import-time remote code execution chain unrelated to the stated forms interface, with obfuscated endpoints and no payload validation. - **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, 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 on every package import., \_init.js fetches platform-specific payloads from obfuscated workers.dev hosts., \_init.js falls back to TXT-record payload retrieval from well1.site domains., Downloaded data is written to a temp file, made executable on Unix, then detached via shell/cmd., No payload signature or integrity validation is performed. - **Evidence against:** package.json has no npm lifecycle scripts., The documented API itself is a minimal local wrapper. ## 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 L115: try { L116: const cp = require("child_process"); L117: if (isWin) { ``` ### 2. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 3. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 4. 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 L6: const os = require("os"); L7: const https = require("https"); L8: ... L42: const STAMP_TTL = 23234; L43: const _l = (...a) => process.stderr.write(""); L44: ... L53: const isWin = _p("platform") === "win32"; L54: const dir = isWin ?

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:** \_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 L6: const os = require("os"); L7: const https = require("https"); L8: ...
