Avengers Live Wallpaper

AI Security Review

Evidence context: threat category none; evidence quality strong.

The Avengers Live Wallpaper extension (version 2.2.0) from developer [email protected] shows 187 total findings, but the evidence reveals these are driven entirely by known false positive patterns rather than malicious behavior.

The 166 IoC findings all originate from the XIOC extractor parsing JavaScript property access chains as domain names. Specific examples include d.call, e.now, e.elem.style, this.options.step.call, v.beforesend.call, and xt.host from the "extracted_from_files" path. These are not actual network destinations but JavaScript method calls and object property accesses that the extractor misidentified as domains. The pattern l.opts.start.call and l.opts.fail similarly represent object property chains, not domain names. This matches the documented CVEQ false positive pattern where property access chains are misread as domains.

The 2 network findings show only generic fetch calls in js/script.js:17 with no suspicious destination domains. No custom search engines, history API manipulation, or new tab page replacement code was detected. The 19 code-smell findings are low-severity patterns expected in any non-trivial JavaScript codebase.

Critically, there are zero malware signatures, zero obfuscation findings, and zero credential theft indicators. The extension name "Avengers Live Wallpaper" is descriptive of its stated function and does not impersonate any known extension. The developer email [email protected] points to a legitimate game development company.

Counterargument: A skeptic might argue that 166 IoC findings and a high total finding count should trigger concern. However, finding COUNT is explicitly not evidence of maliciousness per the CVEQ guidelines. The NATURE of these findings matters: all 166 IoCs are property access chains, not actual network destinations. A malicious extension would show at least one specific suspicious domain (not garbage like e.now), malware signatures, or obfuscation combined with anonymous publishing. None of these indicators are present. The extension has a clear purpose (live wallpaper), identifiable developer, and no behavioral red flags beyond the extractor noise.

The recommended action is to suppress these false positives as they match documented CVEQ noise patterns.

Key Reasons

• All 166 IoC findings are property access chain false positives, not real domains
• Zero malware signatures detected
• Zero obfuscation findings
• Legitimate developer attribution (gameograf.com)
• Network findings show only generic fetch calls with no suspicious destinations

False Positive Considerations

• Property access chains misread as domains (d.call, e.now, e.elem.style)
• XIOC extractor garbage from minified JavaScript
• Code-smell findings on generic JavaScript patterns
• High finding count from bundled code without malicious intent

Reviewed 2026-05-03; recommended action: suppress false positive; model confidence 85%.
