It caches a cooldown marker, downloads a platform-specific binary, then executes it detached. - **Trigger:** require("cardsmobile-notifications") or any import resolving index.js - **Impact:** Arbitrary attacker-controlled code executes under the importing process user. - **Evidence paths:** package.json, index.js, \_support.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:33:00.958Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote binary download, drop, chmod, and detached execution - **Attack narrative:** The main entry point suppresses errors while requiring \_support.js. That module runs immediately unless telemetry opt-out variables are set, fetches a platform-specific payload from obfuscated remote hosts or DNS TXT records, writes it to a temporary path, makes non-Windows files executable, and launches it detached through a shell or cmd.exe. The payload is neither authenticated nor validated beyond size. - **Rationale:** This is a concrete import-time remote code execution chain, not package-aligned telemetry. The dormant-looking telemetry module contains the same downloader/launcher pattern, reinforcing intent. - **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports ./\_support at package import time., \_support.js downloads platform payloads over HTTPS or DNS TXT., \_support.js writes payloads to /var/tmp or Windows Temp, chmods them, then spawns them detached., Remote hosts are obfuscated workers.dev domains with .ru DNS fallback., No signature or integrity verification precedes execution. - **Evidence against:** package.json has no lifecycle scripts., The declared API in index.js is otherwise minimal. ## Public findings ### 1.
