It retrieves, writes, and detached-executes an unverified binary. - **Trigger:** Any Node.js require/import of index.js. - **Impact:** Arbitrary attacker-controlled native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-07T21:20:12.136Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download/DNS staging followed by detached execution - **Attack narrative:** index.js catches and suppresses errors while importing \_vendor.js. That module selects an OS payload, fetches it from concealed Workers hosts or reconstructs it via DNS TXT records, stores it in a temporary directory, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. The package therefore enables attacker-controlled code execution whenever its main entrypoint is imported. - **Rationale:** The concrete import-time staged payload chain is independently confirmed in source. Absence of an npm lifecycle hook does not mitigate execution on normal package use. - **Files touched:** index.js, \_vendor.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, 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 \_vendor on every package import., \_vendor.js downloads platform binaries over HTTPS or DNS TXT., \_vendor.js writes payloads to /var/tmp or Windows Temp, chmods them, then launches detached shells., Remote hosts and DNS domains are obfuscated by string concatenation., No lifecycle hook is needed: import-time execution makes the attack reachable. - **Evidence against:** package.json has no install lifecycle scripts., lib/telemetry.js exposes a telemetry API, but the malicious loader is separately auto-imported. ## Public findings ### 1.
