LPM AI assessed this version as suspicious; the assessments disagree. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Trusted malware advisory block - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 5.4.2 - **Selected version is latest:** Yes - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-10684 identifies this version as malicious and supplies the Firewall block. LPM AI assessed this version as suspicious; the assessments disagree. Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree. OpenSSF/OSV advisory MAL-2026-10684 confirms this npm version as malicious. The package's default export \`getPlugin\` fetches a JSON document from the hardcoded endpoint https://svganchordev.net/icons/108 and passes the returned \`credits\` field to \`new Function('require','module','exports',...,'Promise', data.credits)\`, executing the server-supplied string as JavaScript with full Node.js globals (require, process, Buffer) available... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-07-16T08:26:58.021Z - **Finished:** 2026-07-16T08:27:47.227Z - **Download time:** 509 ms - **Static scan time:** 47 ms - **AI review time:** 48649 ms - **Total time:** 49206 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:** The default export downloads JSON from a hard-coded host and executes the \`credits\` field as Node-capable JavaScript. This is an on-demand staged remote-code loader, not install-time execution. - **Trigger:** A consumer imports and calls the default export \`getPlugin()\`. - **Impact:** The endpoint can supply arbitrary code able to use process and require available local modules. - **Evidence paths:** package.json, index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-16T08:27:47.227Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Fetches and evaluates remotely supplied JavaScript with Node globals. - **Rationale:** Source confirms a concealed remote payload execution primitive, but the package contains no observed payload and does not invoke it at install or import time. Treat it as a staged payload carrier requiring a warning rather than a confirmed active malicious chain. - **Files touched:** package.json, index.js, README.md - **Network endpoints:** https://svganchordev.net/icons/108 ### Review decision - **Verdict:** Suspicious - **Confidence:** 98.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for AI warning decision:** \`index.js\` fetches \`https://svganchordev.net/icons/108\`., \`index.js\` passes response field \`data.credits\` to \`new Function\`., Remote code receives \`require\`, \`process\`, \`global\`, \`Buffer\`, and filesystem-relative module resolution., \`README.md\` documents React hooks that \`index.js\` does not export., \`package.json\` has no lifecycle hooks; remote loader runs only when its default export is called. - **Evidence against:** No install, preinstall, postinstall, or prepare script exists in \`package.json\`., No direct credential harvesting, file writes, shell execution, or exfiltration code appears in package source., \`getPlugin\` is exported but not invoked during module initialization. ## Affected versions and remediation This report applies to react-hook-scripts@5.4.2. - Avoid installing react-hook-scripts@5.4.2. 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. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 2.
