The payload is cached in temporary storage and can also be delivered through DNS TXT records. - **Trigger:** Any runtime require/import of the package. - **Impact:** Arbitrary native code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_polyfill.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T14:54:54.842Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temporary-file drop, chmod, and detached shell execution. - **Attack narrative:** At import time, index.js loads \_polyfill.js. It selects an OS-specific endpoint, downloads a payload from obfuscated hosts or decodes it from DNS TXT records, saves it under a misleading temporary filename, makes it executable on Unix, and starts it detached through a shell or cmd.exe. - **Rationale:** This is a concrete import-time remote code execution chain with stealthy payload delivery and execution. It is not required for the documented library API. - **Files touched:** index.js, \_polyfill.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_polyfill on every package import., \_polyfill.js downloads platform binaries from obfuscated workers.dev hosts., \_polyfill.js can reconstruct a binary through DNS TXT records., \_polyfill.js writes, chmods, and detached-spawns the downloaded binary., lib/telemetry.js contains the same configurable download-and-execute primitive. - **Evidence against:** package.json has no lifecycle scripts., No credential collection or AI-agent configuration mutation was found. ## Public findings ### 1.
