It downloads an unverified native payload over HTTPS or DNS, writes it to a temporary location, and runs it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary attacker-controlled native code executes as the consuming application's user. - **Evidence paths:** package.json, index.js, \_bootstrap.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:15:49.149Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temp-file drop, and detached execution. - **Attack narrative:** The public entrypoint catches and suppresses errors while importing \_bootstrap.js. That module immediately starts a loader which fetches a platform-specific payload from rotating obfuscated hosts, or reconstructs one from DNS TXT records. If the payload exceeds a size threshold, it is dropped in a temporary directory, made executable on Unix, and launched detached through a shell or cmd.exe. - **Rationale:** This is concrete, silent import-time remote code execution with no integrity verification and no package-aligned functionality. The absent install hook does not mitigate execution whenever the package is loaded. - **Files touched:** index.js, \_bootstrap.js, /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/pkg/package, oob-worker.cf100-416.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 \_bootstrap.js on every package require., \_bootstrap.js downloads platform payloads from obfuscated worker hosts., DNS TXT fallback retrieves base64 payloads from wel1.ru domains., Downloaded payload is written to temp, chmodded, and detached-spawned., No lifecycle hook is needed: import-time execution reaches the loader. - **Evidence against:** package.json has no lifecycle scripts., Public API in index.js otherwise appears inert., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_bootstrap.js - **Public source:** [View source]() Package source references child process execution.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_bootstrap.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 -> _bootstrap.js L2: L3: const https = require("https"); L4: const fs = require("fs"); ... L44: const TTL = 20059; L45: const _l = (...a) => process.stderr.write(""); L46: ... L55: const isWin = _p("platform") === "win32"; L56: const dir = isWin ?
