Spider-Man Live Wallpaper New Tab

AI Security Review

Evidence context: threat category none; evidence quality strong.

This Spider-Man live wallpaper extension exhibits the textbook false-positive pattern documented in CVEQ's IoC extractor. The 605 IoC findings are all from the XIOC-DOMAIN category, and examining the actual domains reveals they are extraction artifacts, not real network destinations. Domains like qܞ.ug, ǫ.fo, and ҥ.sj contain non-ASCII characters (Armenian ܞ, Latin ǫ, Cyrillic ҥ) that cannot be valid domain names in the DNS system. These are hex/unicode substrings from minified JavaScript that the XIOC extractor misread as domains. Similarly, short domains like e.bn, f.dk, j.es, and r.dz follow the pattern of property access chains (e.g., e.bn from element.body) being parsed as domains.

Critically, the evidence shows zero malware signatures and zero obfuscation findings. If this extension contained actual malicious code, we would expect to see at least one malware signature or obfuscation indicator, especially with 605 IoCs. The absence of these high-confidence threat indicators is the strongest signal that the findings are noise. The 22 code-smell findings are also consistent with benign JavaScript code triggering rules like postinstall_* or credential_* on basic patterns.

The extension's purpose—displaying Spider-Man live wallpaper on the new tab page—aligns with its name and description. The developer email [email protected] provides traceable attribution, unlike anonymous publishers who typically hide behind no contact information. The 2 network findings are too few to warrant concern without specific suspicious domains attached.

Counterargument: A skeptic might argue that 605 IoCs cannot all be false positives and that some real malicious domains are buried in the noise. However, this reasoning ignores the documented XIOC extractor behavior that produces exactly this pattern: hundreds of garbage domains with non-ASCII characters and property-access-like patterns. The zero malware signatures and zero obfuscation findings directly contradict the hypothesis of malicious code. If malicious code were present, the YARA rules would have triggered at least one malware signature or obfuscation finding. The verdict stands because the nature of the findings (XIOC garbage) matters far more than the count.

Recommendation: Suppress these false-positive IoC findings. The extension does not warrant takedown or monitoring beyond normal store review processes.

Key Reasons

• Zero malware signatures and zero obfuscation findings
• XIOC-DOMAIN findings contain non-ASCII characters impossible in real DNS
• Extension purpose matches stated functionality (live wallpaper)
• Developer email provides traceable attribution
• Code-smell findings are benign JavaScript patterns

False Positive Considerations

• XIOC-DOMAIN findings with non-ASCII characters (qܞ.ug, ǫ.fo, ҥ.sj) are extraction artifacts
• Zero malware signatures despite 605 IoC findings
• Zero obfuscation findings
• Short domain patterns (e.bn, f.dk) are property access chain misreads
