DNS TXT records provide a fallback payload channel. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Unconsented arbitrary code execution under the importing process account. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:30:42.155Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote payload download and detached native execution - **Attack narrative:** The main entrypoint imports \`\_vendor.js\` during normal package loading. That module selects a platform payload path, downloads bytes from obfuscated hosts or reconstructs them from DNS TXT records, drops the result into a temporary directory, marks it executable on Unix, and starts it via a detached shell or cmd.exe process. The behavior is hidden behind telemetry-style naming and has no relation to the documented utility API. - **Rationale:** This is a concrete import-time remote-code-execution chain, not merely a network or telemetry primitive. The payload source is remote and unverified, then executed without user action. - **Files touched:** index.js, \_vendor.js, /tmp/.analytics\_state, /var/tmp - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.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:30 imports \_vendor on every package import., \_vendor.js:24-46 assembles four workers.dev hosts and .ru DNS domains., \_vendor.js:149-160 downloads a platform payload or reconstructs one from DNS TXT., \_vendor.js:169-175 writes the payload to temp, chmods it, and executes it detached., \_vendor.js:178 invokes this chain at module load. - **Evidence against:** package.json has no lifecycle scripts., Public utilities in index.js are otherwise simple local helpers. ## Public findings ### 1.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_vendor.js - **Public source:** [View source]() A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior. Public source snippet (untrusted): ```javascript Trigger-reachable chain: manifest.main -> index.js -> _vendor.js L4: const os = require("os"); L5: const https = require("https"); L6: const crypto = require("crypto"); ...
