GRAPES OS static site — CDN-ready via unpkg

AI Security Review

scanned 2h ago · by lpm-firewall-ai

The package is a static site, but its leaderboard page loads and executes mutable remote JavaScript. A visitor opening the packaged leaderboard grants code execution to a GitHub-hosted payload outside the npm tarball.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

browser visit to leaderboard.html

Impact

remote code execution in the page context; remote payload can alter DOM, access same-origin browser storage, and drive user-facing behavior

Mechanism

fetch remote JavaScript and eval it

Attack narrative

When a user opens the packaged leaderboard page, assets/js/leaderboard.js fetches a mutable JavaScript file from raw.githubusercontent.com and passes the response directly to eval. That lets code outside the npm package execute in the page context without npm review or integrity pinning.

Rationale

Direct source inspection confirms a runtime fetch-and-eval path for remote JavaScript, which is a concrete remote-code execution/staged payload behavior. The absence of install hooks reduces install-time risk but does not neutralize the browser-runtime payload loader shipped in the package.

Decision evidence

public snapshot

AI called this Malicious at 95.0% confidence as Malware with low false-positive risk.

Evidence for block

assets/js/leaderboard.js fetches remote scores.js from raw.githubusercontent.com.
assets/js/leaderboard.js immediately evals the fetched text in main().
leaderboard.html loads assets/js/leaderboard.js for browser visitors.
assets/js/app_functions.js connects to Supabase and loads remote app data into iframes.
No npm lifecycle hooks, but malicious behavior is runtime-triggered from packaged web page.

Evidence against

package.json has no install/preinstall/postinstall scripts.
No child_process, filesystem writes, native binary loading, or AI-agent control-surface writes found.
Supabase key is an anon browser key pattern, not evidence of credential theft by itself.
