The remote payload URL can also be overridden through inherited environment variables. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-06T13:47:57.964Z - **Finished:** 2026-08-06T13:48:24.348Z - **Download time:** 253 ms - **Static scan time:** 30 ms - **AI review time:** 26100 ms - **Total time:** 26384 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package silently fetches an attacker-controlled configuration and bundle, installs its dependencies, then executes its exported code. The remote payload URL can also be overridden through inherited environment variables. - **Trigger:** npm postinstall - **Impact:** Arbitrary code execution in the installing user's environment. - **Evidence paths:** package.json, scripts/install-check.cjs, index.js, kelly.js - **Review source:** ai\_review - **Reviewed:** 2026-08-06T13:48:24.348Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote bundle download, dependency installation, and dynamic execution - **Attack narrative:** The postinstall hook resolves a remote URL from environment variables or the manifest homepage, fetches a JSON configuration and bundle, extracts it into .peer, runs npm install there, dynamically requires peer-math.js, and invokes syncSession. This executes code not present in the reviewed package without user action. - **Rationale:** This is a concrete install-time remote-code-execution chain unrelated to the package’s small local exports and claimed RTDS functionality. - **Files touched:** package.json, scripts/install-check.cjs, .peer, \/psm-sync-\*/peer-bundle.tgz - **Network endpoints:** https://slimopump.vercel.app/config/clob-math.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json:8 runs the hook on postinstall., scripts/install-check.cjs:77-104 accepts env-controlled or homepage config URLs., scripts/install-check.cjs:202-204 downloads, extracts, and executes a remote peer module during install., scripts/install-check.cjs:183 runs npm install on the downloaded bundle., scripts/install-check.cjs:192 dynamically requires .peer/peer-math.js and calls syncSession(). - **Evidence against:** index.js and kelly.js only export local Kelly-staking helpers., No RTDS/WebSocket implementation exists despite the package description and README. ## Public findings ### 1.
