AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. This is a concrete unconsented install-time remote-code-execution chain, not a package-aligned dependency check. The benign exported helpers do not mitigate the malicious lifecycle behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-07-14T07:47:45.219Z - **Finished:** 2026-07-14T07:48:35.474Z - **Download time:** 261 ms - **Static scan time:** 20 ms - **AI review time:** 49974 ms - **Total time:** 50255 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installation triggers unpinned remote payload retrieval and execution. The remote configuration can select the bundle, including through environment overrides and redirects. - **Trigger:** Automatic npm \`postinstall\` execution. - **Impact:** Arbitrary code execution in the installing user's environment with npm install privileges. - **Evidence paths:** package.json, scripts/install-check.cjs, index.js, kelly.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-14T07:48:35.474Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote bundle download, extraction, dependency installation, dynamic require, and immediate execution. - **Attack narrative:** On npm installation, the postinstall script fetches a JSON config from the declared homepage unless overridden by environment variables. That config supplies a remote \`.tgz\`; the script follows redirects, extracts it into \`.peer/\`, runs \`npm install\` in that directory, dynamically loads \`.peer/peer-math.js\`, and invokes \`syncSession()\`. The downloaded code is neither pinned nor verified, so the package publisher or config host can execute arbitrary code on every install. - **Rationale:** This is a concrete unconsented install-time remote-code-execution chain, not a package-aligned dependency check. The benign exported helpers do not mitigate the malicious lifecycle behavior. - **Files touched:** package.json, scripts/install-check.cjs, .peer/, .peer/peer-math.js, .peer/node\_modules/ - **Network endpoints:** https://jipred.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 block:** \`package.json\` runs \`scripts/install-check.cjs\` as \`postinstall\`., Install script obtains a config URL from environment or the package homepage., It fetches an attacker-controlled bundle URL, follows redirects, and writes a \`.tgz\` locally., It extracts the bundle into \`.peer/\`, runs \`npm install\` there, then requires \`.peer/peer-math.js\`., It immediately invokes the remotely supplied module's \`syncSession()\` during installation., README/package naming describe a different package, inconsistent with the install payload. - **Evidence against:** \`index.js\` and \`kelly.js\` only export local Kelly-stake math helpers., No credential harvesting or exfiltration appears in the shipped runtime entry points. ## Affected versions and remediation This report applies to polymarket-bot-logger@1.0.1. - Avoid installing polymarket-bot-logger@1.0.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
