Kuromi Skeleton & Flying Hearts - A Dark Yet Cute Adventure!

AI Security Review

Evidence context: threat category none; evidence quality weak.

This extension appears to be a harmless cosmetic browser theme. The description ("Add a mix of mischief and sweetness...") explicitly frames it as a visual customization rather than a functional tool, which aligns with the "Kuromi" intellectual property from Sanrio. Crucially, the provided evidence bundle contains zero findings across all categories (YARA, IoC, typosquatting, etc.). While this data absence prevents a 100% confirmation, there are no indicators of compromise such as obfuscation, suspicious domains, or credential theft logic. The developer uses a generic Gmail address, which is common for hobbyist theme creators. Given the lack of negative signals and the low-risk nature of static themes (which typically lack the extensive permissions required for data exfiltration), this is assessed as safe for use.

Key Reasons

• Zero security findings in the evidence bundle
• Extension category implies a low-risk static theme
• No evidence of typosquatting or brand impersonation
• No history manipulation or hijacking indicators

False Positive Considerations

• Insufficient data to verify code quality
