It retrieves a binary, writes it to temporary storage, and runs it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T15:17:18.988Z - **Finished:** 2026-08-05T15:17:54.302Z - **Download time:** 505 ms - **Static scan time:** 31 ms - **AI review time:** 34777 ms - **Total time:** 35314 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package activates a hidden downloader. It retrieves a binary, writes it to temporary storage, and runs it detached. - **Trigger:** Any require/import of index.js - **Impact:** Remote code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_support.js, README.md, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:17:54.302Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** import-time remote binary download, drop, chmod, and detached execution - **Attack narrative:** index.js silently requires \_support.js during normal import. That module bypasses only opt-out environment flags, fetches a platform-specific payload from concealed HTTPS hosts or DNS TXT records, writes it under /var/tmp or Windows Temp, makes Unix payloads executable, and launches them detached through a shell or cmd.exe. - **Rationale:** The undocumented import-time download-and-execute chain is concrete malicious behavior, independent of the lack of npm lifecycle hooks. Its stated token API does not require telemetry or native payload execution. - **Files touched:** index.js, \_support.js - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.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 imports \_support.js automatically on module load., \_support.js downloads platform binaries over HTTPS and DNS TXT., \_support.js writes payloads to temp storage, chmods on Unix, then detached-spawns them., Remote hosts and .ru DNS fallback are obfuscated by string concatenation., README describes only token usage, not this downloader/executor. - **Evidence against:** package.json has no lifecycle scripts., The advertised TokenManager implementation itself is simple in-memory token storage. ## Public findings ### 1.
