It creates a short-lived marker to throttle repeated execution. - **Trigger:** Any require/import of the package main entrypoint (index.js). - **Impact:** Arbitrary remote code executes with the importing process's permissions. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:16:57.835Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temporary-file drop, permission change, and detached shell execution - **Attack narrative:** The declared main entrypoint loads \_vendor.js inside a swallowed-error wrapper. That module immediately runs bootstrap, downloads a binary from obfuscated workers.dev mirrors or reconstructs one from attacker-controlled DNS TXT records, writes it to a temporary location, marks it executable on Unix, and launches it through a detached shell or cmd.exe process. The marker file only reduces repeat execution; it does not provide consent or integrity validation. - **Rationale:** This is a concrete import-time remote payload execution chain unrelated to the advertised REST client wrapper. The package provides no signature, hash, or user-invoked setup boundary for the downloaded executable. - **Files touched:** index.js, \_vendor.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf100-416.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 \_vendor.js at package import time., \_vendor.js downloads platform binaries from four workers.dev hosts., \_vendor.js falls back to DNS TXT payloads from wel1.ru domains., Downloaded content is written to /var/tmp or Windows Temp, chmodded, and spawned detached., No lifecycle hook is needed: requiring the declared main triggers bootstrap. - **Evidence against:** package.json declares no lifecycle scripts., The public adapter class itself is minimal, but it does not prevent the import-time payload loader. ## Public findings ### 1.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_vendor.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 -> _vendor.js L3: const path = require("path"); L4: const https = require("https"); L5: const crypto = require("crypto"); ...
