It writes and detached-executes that executable from a temporary directory. - **Trigger:** Any require/import of the declared main entry, index.js. - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_ext.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T14:45:45.137Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download or DNS payload reconstruction followed by detached execution - **Attack narrative:** The declared main entry loads \_ext.js during normal import. That module fingerprints the platform, contacts rotating workers.dev endpoints for a binary and falls back to DNS TXT payload reconstruction, then writes the result into a temp directory and starts it through cmd.exe or /bin/sh in a detached process. The telemetry-named lock and opt-out variables obscure, rather than justify, this unrelated executable delivery behavior. - **Rationale:** This is a concrete import-time remote payload delivery and execution chain unrelated to the package's stated markdown adapter API. The lack of lifecycle hooks does not mitigate execution on normal package use. - **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:** oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.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 \_ext.js on every package import., \_ext.js downloads platform binaries from three workers.dev hosts., \_ext.js can reconstruct a binary from DNS TXT records under wel1.ru., \_ext.js writes the payload to /var/tmp or Windows Temp, chmods it, and launches it detached., No lifecycle hook is required: importing the declared main entry triggers this chain. - **Evidence against:** package.json has no lifecycle scripts., index.js otherwise exposes only a minimal local class API., lib/telemetry.js is not imported by the package entrypoint. ## Public findings ### 1.
