It downloads a platform-specific binary or DNS-delivered payload, writes it to temporary storage, and executes it detached. - **Trigger:** Any require/import of the main entrypoint index.js. - **Impact:** Arbitrary code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:09:58.990Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote payload download and detached native execution. - **Attack narrative:** The main entrypoint silently requires \_init.js. Its setup routine retrieves a binary from rotating remote hosts, or reconstructs one from DNS TXT records, then stores it under an innocuous temporary filename and executes it through a detached shell or cmd.exe process. The same remote-extension loader is also present in lib/telemetry.js, although it is not imported by the main entrypoint. - **Rationale:** This is a concrete import-time remote code execution chain unrelated to the documented lightweight wrapper, with obfuscated endpoints and no payload verification. - **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.cf100-416.workers.dev/pkg/package, oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf99-9b3.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 automatically on package import., \_init.js fetches platform binaries from four workers.dev hosts., \_init.js falls back to DNS TXT payload retrieval under wel1.ru., Downloaded bytes are written to /var/tmp, made executable, and detached-spawned., No integrity or signature validation is performed before execution. - **Evidence against:** package.json has no lifecycle scripts., The exported wrapper itself is minimal, but import-time initialization is reachable. ## Public findings ### 1.

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 fs = require("fs"); L6: const https = require("https"); L7: const path = require("path"); ...
