Publisher Evidence

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.

AI Security Report

AI Security Review

Evidence context: threat category none; evidence quality weak.

This extension, "Little Twin Stars Cute Unicorn Live Wallpaper Sanrio," is a new-tab wallpaper extension with 9 users published by [email protected]. The CVEQ platform flagged 225 findings — 222 IoCs and 3 network findings — all at medium severity. However, every single IoC finding is a textbook XIOC extractor false positive.

The 222 IoC findings follow a clear pattern: they are JavaScript property access chains misread as domain names. Examples include v.beforesend.call, r.old.call, t.fail, a.empty.fire, ce.fx.off, this.name, l.style, s.data, v.global, r.host, and v.data. These are not real domains — they are fragments of minified or bundled JavaScript code where dot-separated property accesses (e.g., xhr.befonsend.call(), element.style, this.name) were incorrectly parsed as FQDNs by the XIOC extractor. This is a well-documented false-positive pattern in CVEQ, particularly common in webpack/esbuild-bundled output.

The 3 network findings lack any description of what domains or endpoints were contacted, and no specific suspicious URLs are cited. Without knowing what the network findings reference, they cannot be treated as evidence of malicious behavior. The extension's stated purpose — loading HD wallpapers — would legitimately require network requests to fetch image assets.

Critically, there are zero malware signatures, zero obfuscation findings, zero code-smell findings, zero tool-poisoning findings, and zero secret exposures. The absence of malware signatures is particularly significant: if this extension were genuinely malicious, at least one YARA malware rule would be expected to fire.

A skeptic might argue that the sheer volume of findings (225) is concerning and that the wallpaper theme could be social engineering to lure users. However, finding volume driven entirely by XIOC garbage is a known score-inflation pattern — confirmed false positives in CVEQ average a risk score of 83.2 despite being benign. The extension has no deceptive naming patterns (it does not impersonate a known extension), no Cyrillic character substitution, and no suspicious domain infrastructure. The developer email, while generic, is present — unlike fully anonymous malicious publishers.

The evidence is consistent with a simple wallpaper extension built with a modern JavaScript bundler, whose minified output triggered mass XIOC false positives.

Key Reasons

  • All 222 IoC findings are XIOC false positives — JavaScript property chains misread as domains (e.g., v.beforesend.call, r.old.call, a.empty.fire)
  • Zero malware signatures, zero obfuscation, zero code-smell, and zero tool-poisoning findings
  • Extension's stated purpose (wallpaper loading) legitimately requires network access
  • No typosquatting, impersonation, or deceptive naming patterns detected

False Positive Considerations

  • XIOC extractor misread minified JavaScript property access chains as domain names
  • Bundled/minified JS output generating mass IoC garbage from variable names
  • No actual suspicious domains — all IoCs are fragments like 't.name', 'l.style', 's.data'

Reviewed 2026-05-25; recommended action: suppress false positive; model confidence 88%.
