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 moderate.

This live wallpaper extension for the Dodge Challenger generates 308 total findings, but the nature of these findings reveals systematic false positive patterns rather than malicious behavior.

The 291 IoC findings are almost entirely extraction artifacts. The XIOC-DOMAIN-e.call, XIOC-DOMAIN-l.call, XIOC-DOMAIN-he.call, XIOC-DOMAIN-de.call, XIOC-DOMAIN-e.name, XIOC-DOMAIN-a.id, XIOC-DOMAIN-e.id, XIOC-DOMAIN-b.filter.id, and XIOC-DOMAIN-b.find.id findings match the documented false positive pattern of property access chains (e.g., e.call(), a.id) being misinterpreted as domain names. The XIOC-DOMAIN-fonts.gstatic.com finding references a legitimate Google CDN domain, which is explicitly listed as benign infrastructure in the CVEQ guidelines.

Two IoC findings warrant closer inspection: XIOC-DOMAIN-ce.support and XIOC-DOMAIN-t.top. The .top TLD is commonly used for monetization and ad networks, and ce.support could represent a content delivery endpoint. However, these domains alone do not constitute evidence of malicious behavior without corroborating malware signatures or obfuscation.

Critically, the findings_summary shows 0 malware-signature findings and 0 obfuscation findings. According to the threat model, confirmed_malicious verdicts require "Real malware signatures + obfuscation + suspicious domains + deceptive naming." This extension has none of the first three criteria. The 17 code-smell findings are classified as noise per the guidelines, which explicitly state that code-smell findings (severity=low, finding_type=code-smell) should NEVER drive a verdict.

The developer identity "[email protected]" is an email address rather than a verified company name, which is a mild concern. However, the extension category (live wallpaper) does not typically require sensitive permissions, and the absence of credential access, history manipulation, or browser hijacking indicators further supports the benign assessment.

Counterargument: A skeptic might argue that ce.support and t.top represent monetization infrastructure or ad injection, and the email-only developer attribution lacks accountability. However, without malware signatures, obfuscation, or evidence of data exfiltration, these domains alone do not justify a malicious verdict. Live wallpaper extensions commonly include update mechanisms and content delivery endpoints. The overwhelming majority of findings are documented false positive patterns, and the scoring system is known to inflate risk based on IoC volume rather than finding quality.

Key Reasons

  • Zero malware signatures detected
  • Zero obfuscation findings
  • 291 of 308 findings are property access chain false positives (e.call, a.id, b.filter.id patterns)
  • Live wallpaper category has low inherent risk profile
  • Code-smell findings are documented noise per CVEQ guidelines

False Positive Considerations

  • Property access chains misread as domains (e.call, a.id, b.filter.id)
  • Legitimate CDN domains (fonts.gstatic.com)
  • Code-smell YARA rules matching basic JavaScript patterns
  • IoC volume inflation without malware signatures

Reviewed 2026-04-30; recommended action: suppress false positive; model confidence 85%.
