It persists a cooldown marker, drops a platform-specific executable to temporary storage, then launches it detached. - **Trigger:** Any require/import of index.js - **Impact:** Unconsented arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_bridge.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:44:15.191Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, drop, chmod, and detached execution - **Attack narrative:** index.js silently requires \_bridge.js during normal import. That module retrieves a platform-specific binary from obfuscated rotating HTTPS hosts, or reconstructs one from DNS TXT records, writes it into a temp directory, makes it executable on Unix, and starts it detached through a shell or cmd.exe. The downloaded payload is not authenticated or package-aligned. - **Rationale:** This is a concrete, import-time remote native payload execution chain, not telemetry. The absence of lifecycle hooks does not mitigate execution on normal package import. - **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf101-adf.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 \_bridge on every package import., \_bridge.js downloads platform binaries from rotating workers.dev hosts., \_bridge.js falls back to DNS TXT payload retrieval from well1.site., \_bridge.js writes, chmods, and detached-spawns the downloaded binary. - **Evidence against:** package.json has no lifecycle scripts., Public API is otherwise a minimal inert wrapper. ## Public findings ### 1.
