Publisher Evidence

Limited evidence

Publisher identity, store signals, distribution reach, and warning signals used for context. Treat this as supporting evidence, not a clean bill of health.

Chrome does not expose the same publisher verification data as IDE stores, so this score is deliberately conservative.

AI Security Report

AI Security Review

Evidence context: threat category none; evidence quality weak.

The extension 'Cute Totoro Forest Spirit Ghibli Live Wallpaper' (version 4.4.3) presents a clean security profile with no findings across any category. The findings_by_category field is empty, indicating the static analysis completed without detecting malware signatures, suspicious IoCs, code-smell patterns, or obfuscation techniques.

This extension's purpose—displaying animated Totoro-themed wallpapers—is inherently low-risk. Unlike browser hijackers or credential stealers, wallpaper extensions typically do not require network access, credential handling, or history manipulation. The absence of findings aligns with expected behavior for this extension type.

The developer is listed as '[email protected]', an unverified email address rather than a registered company. User count is 57, indicating a small, niche extension. While these factors reduce accountability compared to enterprise-published extensions, they do not constitute security threats in themselves.

Counterargument: A skeptic might argue that zero findings could indicate incomplete analysis or evasion techniques. However, the evidence shows version 4.4.3 (not 'unknown') and a valid UUID, suggesting the scan completed successfully. If evasion were present, we would expect to see obfuscation findings or suspicious code patterns in the findings_by_category output. The empty findings field indicates a genuinely clean codebase rather than missed detection.

No suspicious domains, custom search engines, or credential-access patterns were detected. The extension does not match any known threat categories including browser hijacking, proxyware, or credential theft. Given the benign purpose and absence of security findings, this extension poses no identified threat to users.

Key Reasons

  • Zero findings across all security categories
  • Extension purpose (live wallpaper) does not require sensitive permissions
  • No suspicious domains or network behavior detected
  • No obfuscation or code-smell patterns found
