It retrieves a platform-specific payload over HTTPS or DNS TXT, writes it to a temporary directory, and executes it detached. - **Trigger:** Any require/import of index.js. - **Impact:** Arbitrary attacker-controlled native code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_bridge.js, lib/telemetry.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-02T14:57:43.058Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote payload download and detached execution - **Attack narrative:** The benign-looking index entrypoint suppresses errors while importing \_bridge.js. That module immediately downloads an opaque binary from obfuscated Cloudflare Worker hosts, or reconstructs one from DNS TXT records. It stores the payload in a temporary path, sets executable permissions on non-Windows hosts, and launches it detached through a shell or cmd.exe. - **Rationale:** The package implements an unconsented import-time remote binary loader and executor unrelated to its documented Operations SDK API. This is concrete malicious behavior, not merely telemetry. - **Files touched:** index.js, \_bridge.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, Windows Temp/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.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 \_bridge.js on every package import., \_bridge.js immediately invokes main() without user action., \_bridge.js downloads platform payloads from four obfuscated workers.dev hosts., It falls back to DNS TXT payload retrieval from well1.site domains., Downloaded bytes are written under /var/tmp or Windows Temp, made executable, and detached-spawned., lib/telemetry.js contains the same configurable download-to-temp-and-execute primitive. - **Evidence against:** package.json has no lifecycle scripts., No credential-file harvesting or AI-agent configuration mutation was found. ## Public findings ### 1.
