The payload source is selected by OS and has DNS TXT fallback. - **Trigger:** Any require/import of the package entrypoint. - **Impact:** Arbitrary attacker-controlled native code can execute with the importing user's privileges. - **Evidence paths:** package.json, index.js, \_ext.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:56:14.415Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download or DNS payload reconstruction, temp-file drop, and detached process execution. - **Attack narrative:** The exported entrypoint suppresses errors while importing \_ext.js. That module immediately downloads a platform-specific binary from rotating external hosts, or reconstructs one from DNS TXT records, stores it under a disguised temporary name, marks it executable on Unix, and launches it detached. This is an unconsented remote-code-execution chain triggered by normal package import. - **Rationale:** The package's simple data-table API does not require binary downloading or execution. Source confirms the dangerous chain is import-time, concrete, and not merely a scanner label. - **Files touched:** index.js, \_ext.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.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 ./\_ext at package import time., \_ext.js downloads platform binaries from obfuscated workers.dev hosts., \_ext.js falls back to DNS TXT payloads under wel1.ru., \_ext.js writes the payload to a temp file, chmods it, then spawns it detached via shell/cmd., Remote execution is unrelated to the advertised data-table API. - **Evidence against:** package.json has no lifecycle scripts., No package-source credential harvesting was found. ## Public findings ### 1.
