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 extension presents 474 total findings, but the evidence reveals a classic false positive pattern. The 455 IoC detections are all single-character or short domains extracted from files: b.ca, q.pf, b.nz, m.rs, ə.ie, k.ao, y.aq, x.lc, 7.ec, o.ie, t.kn, s.bm. These match the documented XIOC extractor garbage pattern where property access chains like b.call or h.next are misread as domain names. The presence of non-ASCII characters (ə.ie) and single-letter subdomains across random TLDs confirms this is extractor noise, not actual network destinations.

Critically, the extension has zero malware signatures, zero obfuscation findings, and zero network findings. The 19 code-smell detections are all low severity, which is expected for any non-trivial JavaScript bundle. There is no evidence of credential theft, browser hijacking, or data exfiltration. The extension's stated purpose as a live wallpaper featuring One Piece character Jinbe with a Hummer is consistent with its name and description.

The developer is identified only by a personal Gmail address ([email protected]) rather than a verified company, and the extension has zero users. While this limits trust signals, it does not indicate malicious intent. The extension category matches its described functionality.

Counterargument: A skeptic might argue that 455 medium-severity IoC findings warrants concern regardless of their nature. However, CVEQ's own documentation confirms IoC count alone is meaningless when the domains are known false positive patterns. The absence of malware signatures is the most important signal here—if this were malicious, at least one YARA rule would have fired on actual malicious code. The single-character domain pattern is a well-documented XIOC artifact, not evidence of command-and-control infrastructure or data exfiltration endpoints. A genuine malicious extension would show obfuscation, malware signatures, or suspicious network activity—none of which appear in this bundle.

Key Reasons

  • 455 IoC findings are single-character domains matching known XIOC false positive pattern
  • Zero malware signatures detected
  • Zero obfuscation findings
  • Zero network activity findings
  • Extension purpose matches stated functionality (live wallpaper)

False Positive Considerations

  • XIOC property access chain misread as domains (b.ca, q.pf, etc.)
  • Code-smell findings on standard JavaScript patterns
  • Single-character domain false positives from minified code

Reviewed 2026-04-27; recommended action: suppress false positive; model confidence 85%.
