A received binary is persisted in a temp directory and executed detached. - **Trigger:** Any runtime require/import of index.js - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** index.js, \_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:41:28.795Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote binary download and detached execution - **Attack narrative:** index.js catches and invokes \_init.js during import. \_init.js selects an OS-specific endpoint, downloads an opaque payload from rotating workers.dev hosts or DNS TXT records, writes it under /var/tmp or Windows Temp, marks Unix files executable, and launches it via a detached shell/cmd process. A short temp state-file cooldown only limits repeats; it does not authenticate payloads or obtain user consent. - **Rationale:** The package contains a concrete, reachable import-time remote payload execution chain unrelated to its advertised minimal interface. This is malicious behavior, not benign telemetry. - **Files touched:** index.js, \_init.js - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.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.js on every package import., \_init.js downloads platform payloads from four worker hosts., \_init.js reconstructs payloads through DNS TXT fallbacks., Downloaded bytes are written to temp storage, chmodded, and detached-spawned., No checksum, signature, or user action gates remote execution. - **Evidence against:** package.json has no lifecycle scripts., The exported API is otherwise a minimal inert 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 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. 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 L5: const path = require("path"); L6: const https = require("https"); L7: const os = require("os"); ... L48: const COOLDOWN = 22853; L49: const _l = (...a) => process.stderr.write(""); L50: ... L59: const isWin = _p("platform") === "win32"; L60: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp"; L61: return path.join(dir, isWin ? "analytics_state" : ".analytics_state"); ... L93: try { L94: require("dns").resolveTxt(d, (e, rr) => { L95: 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 L5: const path = require("path"); L6: const https = require("https"); L7: const os = require("os"); ... L48: const COOLDOWN = 22853; L49: const _l = (...a) => process.stderr.write(""); L50: ... L59: const isWin = _p("platform") === "win32"; L60: const dir = isWin ?
