It fetches an arbitrary platform payload, writes it to temporary storage, and launches it without verification. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Unconsented remote code execution as the importing user's OS account. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:13:55.120Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, chmod, and detached execution - **Attack narrative:** When the package is imported, index.js silently loads \_init.js. That module selects a platform-specific endpoint, retrieves a binary from rotating Worker hosts or DNS TXT records, drops it to a temporary directory, marks it executable on Unix, and starts it detached through /bin/sh or cmd.exe. It does not authenticate the downloaded payload. - **Rationale:** The package's normal import path contains a concealed, unauthenticated remote payload execution chain unrelated to its stated data-mapper/persistence-adapter purpose. This is concrete malware behavior. - **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, 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 \_init.js on every package import., \_init.js downloads platform binaries from worker hosts or DNS TXT records., \_init.js writes the payload to /var/tmp or Windows Temp, chmods it, then detached-spawns it via shell/cmd., Remote payload has no signature or integrity verification., Marker file only rate-limits repeated execution. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or data exfiltration was found in the inspected entrypoint. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_init.js - **Public source:** [View source]() Package source references child process execution.

L90: try { L91: require("dns").resolveTxt(d, (e, rr) => { L92: 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 crypto = require("crypto"); ... L42: const STAMP_TTL = 21694; L43: const _l = (...a) => process.stderr.write(""); L44: ... L54: const isWin = _p("platform") === "win32"; L55: const dir = isWin ?
