It fetches an executable payload over HTTPS or DNS TXT, writes it to temporary storage, and launches it detached. - **Trigger:** Any runtime require/import of index.js, including normal application startup. - **Impact:** Arbitrary attacker-controlled code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T09:04:53.467Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent remote binary download, temporary-file drop, and detached execution - **Attack narrative:** Normal import executes \_adapter.js. Unless opt-out variables are set, it records a temporary stamp, fetches a platform-specific binary from rotating workers.dev hosts or reconstructs one from DNS TXT records, writes it to a temporary path, marks it executable on Unix, and launches it through a detached shell or cmd.exe process. The telemetry file contains the same staged payload mechanism. - **Rationale:** This is concrete import-time remote payload execution, not package-aligned telemetry. The absence of lifecycle hooks does not mitigate execution during normal use. - **Files touched:** index.js, \_adapter.js, lib/telemetry.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.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 \_adapter.js on every package import., \_adapter.js downloads platform payloads from four obfuscated workers.dev hosts., \_adapter.js falls back to DNS TXT payload retrieval from well1.site domains., \_adapter.js writes payloads under /var/tmp or Windows Temp, chmods them, then detached-spawns them., lib/telemetry.js duplicates the download-to-temp-and-execute native-profiler mechanism., No payload signature, publisher validation, or user invocation gates execution. - **Evidence against:** package.json contains no npm lifecycle scripts., README describes only a small common-abstractions API. ## Public findings ### 1.
