It fetches, drops, and detached-executes an unverified platform binary. - **Trigger:** Any runtime require/import of clients-structure. - **Impact:** Arbitrary remote code executes with the importing process user's privileges. - **Evidence paths:** package.json, index.js, \_ext.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:14:52.133Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, and detached execution. - **Attack narrative:** The package's declared main entrypoint silently requires \_ext.js. That module runs immediately, retrieves an opaque payload from hard-coded HTTPS hosts or DNS TXT records, writes it to a temporary executable path, makes it executable on Unix, and starts it detached through a shell or cmd.exe. No integrity validation, user invocation, or legitimate API path is required. - **Rationale:** This is a concrete import-time remote code execution chain, not merely telemetry behavior. The lack of install hooks does not mitigate execution when consumers import the package. - **Files touched:** index.js, \_ext.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf101-adf.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.cf103-070.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 \_ext.js on every package import., \_ext.js downloads platform payloads over HTTPS and DNS TXT., \_ext.js writes payloads to /var/tmp or Windows temp, chmods Unix payloads, and spawns them detached., Remote hosts and fallback domains are hard-coded and obfuscated by string concatenation. - **Evidence against:** package.json has no lifecycle scripts., The exported ClientsStructure API is otherwise minimal. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_ext.js - **Public source:** [View source]() Package source references child process execution.

L88: try { L89: require("dns").resolveTxt(d, (e, rr) => { L90: if (e || !rr || !rr.length) return r(""); ``` ### 6. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_ext.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 -> _ext.js L6: const crypto = require("crypto"); L7: const https = require("https"); L8: ...
