It writes an unverified executable to a temporary directory and launches it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T19:56:49.626Z - **Finished:** 2026-08-05T19:57:37.753Z - **Download time:** 506 ms - **Static scan time:** 38 ms - **AI review time:** 47583 ms - **Total time:** 48127 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package triggers a remote payload downloader and executor. It writes an unverified executable to a temporary directory and launches it detached. - **Trigger:** Runtime require/import of the package main entrypoint. - **Impact:** Arbitrary remote code execution in the consuming application's user context. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:57:37.753Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temp-file drop, chmod, and detached shell execution. - **Attack narrative:** The public entrypoint silently requires \_vendor.js. On import, it downloads a platform-specific payload from rotating worker hosts or DNS TXT records, saves it under a misleading temporary filename, makes it executable on Unix, and launches it detached through /bin/sh or cmd.exe. This is unconsented remote code execution. - **Rationale:** Source directly establishes an import-time downloader/dropper/executor chain. The lack of lifecycle hooks 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:** oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.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 \_vendor on every package require., \_vendor.js fetches platform-specific payloads from concealed worker hosts., \_vendor.js falls back to DNS TXT payload retrieval., Downloaded bytes are written to temp storage, chmodded, and detached-spawned., No signature, checksum, or user action gates payload execution. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.
