It downloads an unverified binary, saves it to a temporary directory, and executes it detached. - **Trigger:** Any require/import of the package entrypoint. - **Impact:** Arbitrary remote code executes with the importing user's privileges. - **Evidence paths:** package.json, index.js, \_platform.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:25:59.875Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, chmod, and detached shell execution. - **Attack narrative:** The normal entrypoint suppresses errors while importing \_platform.js. That module obtains a platform-specific payload over HTTPS, falling back to DNS TXT reconstruction, writes it to a temporary path, marks it executable on Unix, then launches it detached through /bin/sh or cmd.exe. The payload is not integrity-checked. - **Rationale:** This is a concrete import-time remote-code-execution chain disguised as telemetry/profiling support. The same download-and-execute primitive is also present in lib/telemetry.js. - **Files touched:** index.js, \_platform.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf100-416.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.js on every package import., \_platform.js downloads platform binaries from worker hosts or DNS TXT records., Downloaded bytes are written to /var/tmp or Windows Temp, made executable, and spawned detached., No lifecycle hook is needed: the payload path runs at import time. - **Evidence against:** package.json declares no install lifecycle scripts., No AI-agent configuration or credential harvesting was found. ## Public findings ### 1.
