AI Security Report

AI Security Review

Evidence context: threat category none; evidence quality moderate.

The extension "Himiko Toga My Hero Academia Live Wallpaper" generates 247 findings that appear alarming at first glance, but careful examination reveals they stem entirely from known false positive patterns documented in the CVEQ system.

The 224 IoC findings are artifacts of the XIOC extractor misinterpreting JavaScript property access chains as domains. Specific examples from the evidence include c.postdispatch.call, this.target, date.now, e.target, f.add.call, and ce.event.handlers.call — all standard JavaScript syntax, not network destinations. This matches the documented false positive pattern where property access chains are incorrectly flagged as domains. The IoC finding XIOC-DOMAIN-date.now at file path extracted_from_files is particularly telling: date.now is a JavaScript method call, not a domain name.

The 21 code-smell findings are classified as low severity, which the guidelines explicitly identify as noise that should never drive a verdict. These match basic JavaScript patterns expected in any non-trivial codebase.

The 2 network findings show a generic fetch call in js/script.js:17, but provide no evidence of data exfiltration or connection to suspicious infrastructure. The finding title NET-FETCH-js/script.js-17 contains no domain destination, only confirms the presence of a fetch statement.

Critically, there are zero malware signatures, zero obfuscation findings, and no manifest analysis issues. The extension's stated purpose — a fan wallpaper for My Hero Academia — aligns with its codebase structure. The developer email [email protected] is typical for fan projects and not inherently suspicious.

A skeptic might argue that 224 IoC findings and an anonymous developer email warrant concern. However, finding count is explicitly not evidence — finding nature is. The IoCs are demonstrably JavaScript property access patterns, not real domains. The developer email is standard for fan-made extensions. Without malware signatures, obfuscation, or evidence of credential theft, browser hijacking, or data exfiltration, there is no basis for a malicious verdict. The evidence quality is moderate: we have comprehensive findings, but they are all from known false positive patterns rather than actual suspicious behavior.

Key Reasons

  • All 224 IoC findings are JavaScript property access patterns (c.postdispatch.call, this.target, date.now), not real domains
  • Zero malware signatures or obfuscation findings present
  • Code-smell findings classified as low severity noise per CVEQ guidelines
  • Network finding shows generic fetch with no suspicious destination domain

False Positive Considerations

  • XIOC property access chains misread as domains
  • Low-severity code-smell findings
  • High IoC count from extractor noise not actual domains
  • No malware signatures or obfuscation present

Reviewed 2026-04-30; recommended action: suppress false positive; model confidence 85%.
