It uses HTTPS hosts and DNS TXT records as payload sources. - **Trigger:** Any application or tool that requires/imports index.js. - **Impact:** Arbitrary attacker-hosted native code can execute with the importing process's privileges. - **Evidence paths:** package.json, index.js, setup.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-02T10:20:28.509Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote payload download, temp-file drop, chmod, and detached execution. - **Attack narrative:** Requiring index.js silently loads setup.js. That code selects an OS-specific asset path, downloads an opaque payload from rotating workers.dev hosts or reconstructs one from DNS TXT records, writes it to a temporary location, makes it executable on Unix, and launches it detached through /bin/sh or cmd.exe. The same downloader/executor pattern is also present in lib/telemetry.js. - **Rationale:** This is a concrete import-time remote-code-execution chain, not ordinary telemetry. The absence of npm lifecycle hooks does not mitigate activation through the package main entrypoint. - **Files touched:** index.js, setup.js, /tmp/.analytics\_state, /var/tmp - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.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 ./setup at module load., setup.js downloads platform binaries from rotating workers.dev hosts., setup.js falls back to DNS TXT payload retrieval from well1.site., setup.js writes payloads to temp storage, chmods non-Windows files, then spawns them detached via shell., No lifecycle hook is needed: requiring the declared main activates the chain. - **Evidence against:** package.json contains no lifecycle scripts., The exported banner class itself is inert, but its import-time side effect is not. ## Public findings ### 1.
