It creates a short-lived marker and drops the received binary into a temporary directory. - **Trigger:** Runtime import/require of index.js - **Impact:** Arbitrary remote code executes with the importing process user's privileges. - **Evidence paths:** package.json, index.js, setup.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-01T11:33:18.220Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote payload download, drop, detached execution, and cleanup - **Attack narrative:** Requiring index.js silently requires setup.js. That module retrieves a platform-specific executable from obfuscated Workers hosts, or decodes one from DNS TXT records, writes it to a temporary location, makes it executable on Unix, and starts it detached with output suppressed. It then deletes the dropper artifact after five seconds. - **Rationale:** This is an import-time staged remote-code-execution chain unrelated to the advertised adapter or stated telemetry. No signature, hash, or user action protects the downloaded executable. - **Files touched:** index.js, setup.js, /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.cf100-416.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf103-070.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 ./setup at module load., setup.js downloads platform-specific payloads over HTTPS and DNS TXT., Downloaded buffer is written to /var/tmp or Windows Temp, chmodded, then launched detached., Hosts and fallback domains are string-obfuscated; no payload integrity verification exists., The temporary execution artifact is removed after launch. - **Evidence against:** package.json has no lifecycle scripts., The declared SDK entrypoint otherwise contains only a small adapter class. ## Public findings ### 1.
