Publisher Evidence

Limited evidence

[email protected]

Publisher identity, store signals, distribution reach, and warning signals used for context. Treat this as supporting evidence, not a clean bill of health.

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 moderate.

The CVEQ findings for "Mercedes-AMG GT Sanji One Piece Live Wallpaper" (UUID: 43986210-186b-58df-bd35-b8957c7353b8) show 600 total findings, but the evidence does not support a malicious verdict. The 584 IoC findings (all medium severity) consist of short domains like c.dz, g.nl, q.gy, i.am, daj.fo, g.fm, l.no, i.sd, v.ai, 9.bt, s.cu, and a.vu. These are single-character or two-character subdomains on various TLDs, which are common false positives from the XIOC extractor that matches any string resembling a domain pattern in minified JavaScript. The file_path field shows "extracted_from_files" rather than specific source files, indicating these were extracted via regex pattern matching rather than confirmed network activity.

Critically, the findings_summary shows zero malware signatures ("malware-signature":"0"), zero obfuscation findings ("obfuscation":"0"), and zero network findings ("network":"0"). The 16 code-smell findings are all low severity, consistent with YARA rules that fire on any non-trivial JavaScript (postinstall patterns, credential references, etc.). There is no evidence of browser hijacking (no custom search engine domains like query.* or search.*), no credential theft indicators, no typosquatting (the extension name does not impersonate a known brand), and no proxyware functionality.

The developer uses a Gmail address ([email protected]) rather than a company domain, and the user count is only 11. While these are weak signals, they do not constitute evidence of malicious behavior. The extension's stated purpose as a live wallpaper could legitimately require fetching images from external sources, and the short domains could be CDN endpoints or image hosting services.

Counterargument: A skeptic could argue that 584 external domains is excessive for a wallpaper extension and warrants scrutiny. However, the XIOC extractor is documented to produce massive false-positive volumes from property access chains and hex substrings in minified code. Without malware signatures, obfuscation, or confirmed network activity to these domains, the IoC count alone is noise. The verdict would change if runtime analysis confirmed actual communication with these domains or if the domains were known malicious infrastructure.

Key Reasons

  • Zero malware signatures detected in the extension
  • Zero obfuscation findings despite 600 total findings
  • IoC domains are short subdomains typical of XIOC false positive patterns
  • No network findings confirm actual communication with extracted domains
  • Code-smell findings are low severity YARA noise on generic JavaScript patterns

False Positive Considerations

  • XIOC-DOMAIN extractor matching short subdomain patterns in minified code
  • Code-smell YARA rules firing on basic JavaScript patterns
  • Property access chains misread as domain strings
  • High finding count from bundled/minified code without malware signatures

Reviewed 2026-04-27; recommended action: suppress false positive; model confidence 75%.
