Game Pixel Art Mario Lofi Super Mario Live Wallpaper

AI Security Review

Evidence context: threat category none; evidence quality moderate.

This extension, 'Game Pixel Art Mario Lofi Super Mario Live Wallpaper' (version 1.1.1), presents a new tab customization tool with no security findings in the evidence bundle. The developer attribution is present via the email '[email protected]', which is better than completely anonymous publishing. The description clearly states the extension's purpose: providing live wallpapers and lofi beats for the new tab page.

The findings_by_category bucket is completely empty, meaning no IoC findings, no code-smell findings, no obfuscation indicators, and no malware signatures were detected. This absence of findings is significant—malicious extensions typically trigger at least some code-smell rules or IoC matches. The extension name references Nintendo's Mario IP, which raises potential copyright concerns but does not constitute a security threat. There is no evidence of typosquatting since no official Nintendo browser extension exists that this would be impersonating.

New tab extensions are inherently powerful because they control the browser's default landing page, a capability that could be weaponized for browser hijacking or data collection if the extension were compromised. However, the clean findings profile and clear functional description indicate this extension is performing its stated purpose without malicious behavior.

Counterargument: A skeptic could argue that the empty findings bucket indicates the security scan failed to run rather than the extension being clean. This is a valid concern—zero findings could mean incomplete analysis. However, we have complete metadata (developer email, version number, description, user count), which suggests the basic analysis infrastructure functioned. If the scan had failed entirely, we would likely see 'unknown' version or missing fields. The absence of findings in a properly structured metadata record most reasonably indicates a clean scan result rather than a failed one. For higher confidence, runtime analysis could verify the extension's actual behavior, but based on available static analysis evidence, this extension shows no malicious indicators.

Key Reasons

• Empty findings_by_category indicates no malicious code detected
• Developer attribution present ([email protected])
• Clear functional description matches new tab extension category
• No typosquatting indicators or impersonation of known extensions
• Zero user count suggests new/obscure extension but not inherently malicious

False Positive Considerations

• No findings to evaluate for false positives
• Extension type (new tab customization) commonly flagged by generic rules
