It downloads a platform-specific executable, drops it in temporary storage, and launches it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary attacker-controlled native code execution under the importing process's user account. - **Evidence paths:** package.json, index.js, \_init.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:45:24.003Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temp-file drop, and detached execution - **Attack narrative:** On package import, index.js silently requires \_init.js. That module selects a platform payload URL, fetches bytes from obfuscated remote hosts or DNS TXT records, writes the result to a temporary executable file, makes it executable on Unix, and launches it detached. This is an unconsented remote-code-execution loader; telemetry opt-out environment names and a temporary marker disguise rather than prevent the behavior. - **Rationale:** Direct source inspection confirms import-time remote payload retrieval and execution, independent of scanner labels. The same loader pattern is also present in lib/telemetry.js, although the import-time \_init.js path alone establishes malicious behavior. - **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf103-070.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 \_init.js at package import time., \_init.js fetches platform binaries from obfuscated workers.dev hosts., It falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded bytes are written to temp storage, chmodded, and detached-spawned via shell/cmd., No checksum, signature, or trusted package-owned endpoint validation is present. - **Evidence against:** package.json has no lifecycle scripts., The public SDK class itself is minimal; the attack is hidden in its import-time side effect. ## Public findings ### 1.
