It fetches an opaque binary, writes it to a temporary directory, and executes it detached. - **Trigger:** Any require/import of the main index.js entrypoint. - **Impact:** Unconsented arbitrary native code execution with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:30:01.288Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, chmod, and detached shell execution. - **Attack narrative:** Loading index.js requires \_init.js. Its run() function selects a platform endpoint, downloads an opaque binary from rotating worker hosts or DNS TXT records, drops it in a temporary directory, optionally marks it executable, and starts it detached through cmd.exe or /bin/sh. The rate-limit stamp and suppressed errors reduce visibility; no integrity verification is performed. - **Rationale:** This is concrete import-time staged remote code execution unrelated to the exported metrics collector. The absence of lifecycle scripts does not mitigate execution on normal package import. - **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state - **Network endpoints:** https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf101-adf.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 worker hosts or DNS TXT records., \_init.js writes the payload to /var/tmp or Windows Temp, chmods it, then detached-spawns it., Downloaded payload has no signature or hash verification., lib/telemetry.js contains the same configurable download-and-execute profiler mechanism. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent control-surface writes were found. ## Public findings ### 1.
