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

Evidence context: threat category none; evidence quality strong.

This extension, "Ichigo Kurosaki - Bleach Anime Live Wallpaper" (version 5.2), triggers 205 total findings, but every finding represents a documented false positive pattern rather than actual malicious behavior.

The 190 IoC findings are exclusively property access chains being misread as domains by the XIOC extractor. Specific examples include XIOC-DOMAIN-this.target, XIOC-DOMAIN-d.call, XIOC-DOMAIN-e.style, XIOC-DOMAIN-t.click, XIOC-DOMAIN-ce.event.handlers.call, and XIOC-DOMAIN-c.postdispatch.call. These are JavaScript object property access patterns (e.g., this.target, e.style, d.call) that the static analyzer incorrectly interprets as network domains. Per the CVEQ false-positive documentation, property access chains like b.call, h.next, g.id are a well-known noise source that should be discounted.

The remaining 15 findings are all code-smell severity (low), which per the decision framework "should NEVER drive a verdict." These match basic JavaScript patterns and are classified as noise. Critically, there are zero malware signatures, zero obfuscation findings, zero network findings, and zero high or critical severity findings.

The extension's purpose aligns with its description: an anime live wallpaper featuring Ichigo Kurosaki from Bleach. There is no evidence of browser hijacking, credential theft, or malware delivery. The developer name is a Gmail address ([email protected]), which is less trustworthy than a verified company but does not indicate malicious intent. The user count of 6 is low but consistent with a niche anime-themed extension.

Counterargument: A skeptic might argue that the Gmail developer and low user count (6 users) could indicate a throwaway account used for malicious extensions. However, this argument fails because the actual code findings show no malicious behavior whatsoever. If this were a malicious extension, we would expect at least some malware signatures, obfuscation, or suspicious external domains—not 190 false-positive property access chains. The nature of the findings (all garbage IoCs) is stronger evidence than the publisher identity. The extension simply lacks any capability indicators of harm.

The findings are driven entirely by the XIOC extractor's known weakness in parsing JavaScript property access chains. No action is required beyond suppressing these false positives.

Key Reasons

  • All 190 IoC findings are property access chains misread as domains (e.g., this.target, d.call)
  • Zero malware signatures detected
  • Zero obfuscation findings
  • Zero network findings
  • Code-smell findings are low-severity noise per CVEQ guidelines

False Positive Considerations

  • XIOC property access chain misreads (this.target, d.call, e.style)
  • Code-smell findings (low severity, noise)
  • No malware signatures or obfuscation present

Reviewed 2026-05-08; recommended action: suppress false positive; model confidence 88%.
