It leaves a temporary stamp to limit repeat execution. - **Trigger:** Runtime require/import of index.js. - **Impact:** Arbitrary remote code execution under the importing application's user account. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:34:52.875Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, chmod, and detached shell execution. - **Attack narrative:** A normal import loads \_vendor.js. Its bootstrap selects an OS-specific endpoint, downloads an opaque payload from rotating hosts or reconstructs it 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. No integrity verification or user action is required. - **Rationale:** This is a concrete import-time staged-payload execution chain, not telemetry behavior. The lack of lifecycle hooks does not mitigate runtime remote code execution on import. - **Files touched:** index.js, \_vendor.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.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 \_vendor.js on every package import., \_vendor.js downloads platform-specific binary payloads over HTTPS or DNS TXT., \_vendor.js writes payloads to /var/tmp or Windows Temp, marks Unix payload executable, then detached-spawns it., \_vendor.js obscures rotating workers.dev and well1.site endpoints with string concatenation., lib/telemetry.js independently contains the same remote native-profiler download-and-execute mechanism. - **Evidence against:** package.json has no lifecycle scripts., The exported MetricsCollector itself is simple in-memory metrics code. ## Public findings ### 1.
