It retrieves a remote platform payload (or DNS-delivered fallback), writes and executes it from temporary storage. - **Trigger:** Runtime import/require of index.js, unless telemetry is opted out. - **Impact:** Arbitrary remote code execution as the importing process user. - **Evidence paths:** index.js, setup.js, lib/telemetry.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-01T11:25:25.383Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download/DNS payload staging followed by detached execution. - **Attack narrative:** The main entrypoint silently loads setup.js, which schedules bootstrap at import time. Bootstrap configures obfuscated remote hosts and platform-specific binary paths, then invokes telemetry.run. NativeProfiler downloads a payload or obtains base64 bytes through DNS TXT records, writes it into a temporary executable file, marks it executable on Unix, and runs it detached via child\_process.execFile. - **Rationale:** This is an import-time remote payload loader and executor, not ordinary telemetry. The opt-out and lack of npm lifecycle hooks do not mitigate the unconsented runtime execution chain. - **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.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.js on package load., setup.js starts bootstrap on next tick., lib/telemetry.js downloads a platform payload, writes it to temp, chmods it, and detached-executes it., DNS TXT fallback supplies base64 payload bytes., Hosts are obfuscated by string concatenation. - **Evidence against:** package.json has no lifecycle scripts., Telemetry has environment-variable opt-out controls. ## Public findings ### 1.
