This grants the remote library supplier arbitrary native-code execution in the invoking process. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 94.0% - **Started:** 2026-08-24T05:54:16.932Z - **Finished:** 2026-08-24T05:55:04.627Z - **Download time:** 502 ms - **Static scan time:** 282 ms - **AI review time:** 46910 ms - **Total time:** 47695 ms ## Security analysis ### Published attack-surface review - **Summary:** Running the package downloads opaque native shared libraries without pinned integrity and loads them through koffi. This grants the remote library supplier arbitrary native-code execution in the invoking process. - **Trigger:** User runs the snavbox CLI or executes/imports index.js. - **Impact:** Arbitrary code execution and filesystem/network access with the invoking user's privileges. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-24T05:55:04.627Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unverified remote native-library download and in-process loading. - **Rationale:** This is a concrete remote-code-execution chain, not merely network-capable proxy functionality: mutable remote native payloads are downloaded without integrity pinning and executed. The lack of lifecycle hooks limits install-time exposure but does not remove the runtime attack surface. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **Files touched:** .npm/sbx.so, .npm/bot.so, .npm/v1.so, .npm/config.json - **Network endpoints:** https://amd64.oooen.com, https://arm64.oooen.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Malware - **False-positive risk:** Medium - **Evidence for:** Runtime unconditionally downloads native libraries from architecture-specific oooen.com hosts., Downloaded files have no expected SHA-256, so integrity verification always succeeds., The package loads those downloaded libraries with koffi, executing native code in-process., The main entrypoint invokes startServer() automatically when the CLI or module is run. - **Evidence against:** package.json contains no preinstall, install, or postinstall hook., Some upload and Telegram actions require user-supplied environment variables. ## Public findings ### 1.
