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.

The CVEQ platform flags 235 domain indicators for this extension, all produced by the XIOC extractor at medium severity. No malware signatures matched. No obfuscation was detected. No network findings, code-smell findings, or tool-poisoning results exist in the evidence.

Examining the domains, they exhibit clear hallmarks of XIOC false positives: extremely short ccTLD-based tokens like f.cn, i.pl, d.ie, m.mo, d.now, and i.lr. These single-character-plus-TLD patterns are characteristic of the XIOC extractor misreading hex substrings, minified variable names, or locale data as fully qualified domain names. The entry ޖ.cy contains a Unicode Thaana character, further indicating non-Latin script content (possibly i18n strings) being misinterpreted as a domain. None of these domains correspond to known tracker networks, command-and-control infrastructure, or suspicious hosting providers.

The extension's stated function — a new-tab live wallpaper — is a low-risk category that typically loads image or animation assets rather than executable logic. The developer email [email protected] is unattributed, which is a mild concern, but lacks any corroborating threat indicators absent elsewhere in the evidence.

A skeptic might argue that 235 detections at high/unfiltered volume and a zero user count warrant caution. However, the absence of any malware signatures, obfuscation, network anomalies, or code-smell findings means there is no behavioral evidence of malicious activity. The entire finding corpus collapses to one noise source (XIOC) with no supporting indicators from orthogonal analysis modules. Risk scores derived primarily from IoC volume are known to inflate substantially on false-positive extensions.

Key Reasons

  • Zero malware signatures detected despite 235 total findings
  • All flagged domains are short ccTLD patterns consistent with XIOC extractor garbage
  • No obfuscation, network findings, or code-smell results to corroborate malicious behavior
  • Extension category (new-tab wallpaper) is inherently low-risk

False Positive Considerations

  • XIOC extractor misreading minified/non-Latin content as domains
  • Single-character-plus-ccTLD domain patterns are non-actionable noise
  • No orthogonal analysis modules (malware, obfuscation, network) confirm any threat

Reviewed 2026-06-02; recommended action: suppress false positive; model confidence 82%.
