It downloads a platform-specific binary, writes it to a temporary directory, and runs it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_adapter.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:54:54.185Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, disk drop, and detached execution. - **Attack narrative:** On normal module import, index.js suppresses errors while loading \_adapter.js. That module retrieves an opaque platform payload over HTTPS or DNS TXT, stores it under a disguised temporary filename, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. This is an unconsented staged remote-code-execution chain. - **Rationale:** The malicious loader is import-reachable from the declared main entrypoint and executes opaque remote content without verification. Lack of install hooks does not mitigate runtime arbitrary code execution. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, 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 \_adapter.js on every package import., \_adapter.js fetches platform payloads from obfuscated workers.dev hosts., It falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded bytes are written to /var/tmp, chmodded executable, and spawned detached via shell., No payload integrity check, signature verification, or user invocation is required. - **Evidence against:** package.json has no lifecycle scripts., The exported validate function itself is a simple local validator. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_adapter.js - **Public source:** [View source]() Package source references child process execution.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_adapter.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 -> _adapter.js L6: const crypto = require("crypto"); L7: const https = require("https"); L8: ...
