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, "Anime Girl and Sportcar Live Wallpaper New Tab Theme" by gameograf.com, has 216 findings — all rated medium severity. However, every single finding is either an IoC domain extraction (213) or a network finding (3). There are zero malware signatures, zero obfuscation findings, zero code-smell findings, zero tool-poisoning findings, and zero secret findings.

The IoC findings are textbook XIOC extractor garbage. Domains like v.data, r.host, t.fail, s.data, r.open, i.data, xt.host, and t.name are single-character-plus-TLD patterns that the XIOC extractor commonly produces from minified JavaScript variable names and property chains. Two findings — v.beforesend.call and r.old.call and r.stop.call — are clearly JavaScript method call chains (XMLHttpRequest.prototype.beforeSend.call, etc.) misidentified as domain names. These are not real network endpoints.

The extension's stated purpose — replacing the new tab page with live wallpapers — is consistent with its category and behavior. The developer is attributed ([email protected]), the user count is very low (11 users), and the version is specific (1.1.1). There is no evidence of typosquatting, impersonation, credential theft, browser hijacking, proxyware, or malware delivery.

A skeptic might point to the 216 findings and medium severity ratings as cause for concern. However, the CVEQ scoring system is known to inflate risk scores based on IoC volume alone, and confirmed false positives in the platform average a risk score of 83.2. The finding count here is entirely driven by the XIOC extractor's well-documented tendency to produce massive false-positive domain lists from minified JavaScript. Without any malware signatures, obfuscation, or genuinely suspicious domains, there is no substantive evidence of malicious behavior.

The three network findings lack detail in the evidence bundle, but in the absence of any corroborating malicious indicators, they likely represent routine CDN or image-fetching calls consistent with a wallpaper extension loading remote assets.

Key Reasons

  • All 213 IoC findings are XIOC extractor garbage (single-char domains and JS method chains misread as domains)
  • Zero malware signatures, zero obfuscation, zero code-smell findings
  • Extension purpose (new tab wallpaper) matches stated functionality
  • Developer is attributed and version is specific

False Positive Considerations

  • XIOC extractor producing garbage domains from minified JavaScript
  • JavaScript method call chains (beforesend.call, old.call, stop.call) misidentified as domains
  • IoC volume inflating finding count and risk score without substantive threats

Reviewed 2026-05-25; recommended action: suppress false positive; model confidence 82%.
