The payload source can be changed remotely and is also obtainable through DNS TXT records. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary native code executes as the application user. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:32:31.937Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download/write/chmod/detached execution with DNS fallback. - **Attack narrative:** Requiring index.js silently imports \_init.js, which invokes start(). It retrieves a platform-specific payload from obfuscated workers.dev hosts, or reconstructs one from DNS TXT records, writes it into a temporary directory, makes it executable on Unix, and launches it detached through a shell or cmd.exe. The temporary state stamp merely rate-limits the execution attempt. - **Rationale:** This is a concrete import-time remote-code-execution payload loader, not telemetry behavior. The lack of npm lifecycle hooks does not reduce the runtime compromise risk. - **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:** https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, 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 \_init.js on every package import., \_init.js downloads platform binaries from obfuscated workers.dev hosts., \_init.js falls back to DNS TXT payload retrieval from well1.site domains., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, and detached-spawned., No manifest lifecycle hook is needed: import-time start() triggers the chain. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent configuration mutation was found. ## Public findings ### 1.
