The behavior is unrelated to the exported Store API. - **Trigger:** Runtime require/import of bigops-statements-timeline. - **Impact:** Arbitrary attacker-controlled native code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_support.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:42:07.079Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, chmod, and detached execution - **Attack narrative:** Requiring index.js loads \_support.js and immediately calls run(). It contacts rotated workers.dev hosts for a platform-specific payload, with DNS TXT reconstruction from wel1.ru as fallback. A payload over 1000 bytes is dropped in a temporary directory, chmodded on Unix, and launched through a detached shell or cmd.exe process. This is concrete remote code execution hidden behind an unrelated state-store package. - **Rationale:** The package’s normal import path performs stealthy remote payload retrieval and execution, with no user action or documented need. Obfuscated endpoint construction, DNS fallback, temporary binary names, and suppressed errors reinforce malicious intent. - **Files touched:** index.js, \_support.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.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.js on every package import., \_support.js downloads platform binaries from four workers.dev hosts., \_support.js falls back to DNS TXT payload retrieval from \*.wel1.ru., Downloaded bytes are written to /var/tmp or TEMP, made executable, and spawned detached., No lifecycle hook is needed: runtime import triggers run() automatically. - **Evidence against:** package.json contains no lifecycle scripts., No credential harvesting or data exfiltration was confirmed. ## Public findings ### 1.
