It fetches an unverified remote payload, writes it to a temporary directory, and executes it detached. - **Trigger:** Runtime require/import of index.js - **Impact:** Arbitrary remote code executes with the privileges of the importing Node process. - **Evidence paths:** package.json, index.js, \_platform.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:00:40.025Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temporary-file drop, and detached execution - **Attack narrative:** A normal require of the advertised package silently loads \_platform.js. Its import-time start routine selects an OS-specific path, retrieves bytes from obfuscated Workers hosts or DNS TXT records, writes them to a temporary executable path, marks Unix payloads executable, and launches them through a detached shell or cmd.exe. - **Rationale:** This is concrete import-time remote payload execution unrelated to the advertised lightweight wrapper. No integrity verification or user action protects the downloaded executable. - **Files touched:** index.js, \_platform.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf100-416.workers.dev/pkg/package, 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 \_platform on package require., \_platform.js immediately invokes start()., \_platform.js downloads platform binaries over HTTPS or DNS TXT., Downloaded bytes are written under /var/tmp or Windows Temp., \_platform.js chmods and detached-spawns the downloaded file., Remote endpoints include Workers hosts and wel1.ru fallback domains. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by package entrypoints. ## Public findings ### 1.
