Evidence context: threat category none; evidence quality moderate.
The extension "Naruto Luffy and Son Goku Live Wallpaper" (version 1.0, 407 users) shows 607 total findings, but the evidence does not support malicious behavior. The 582 IoC findings reference domains like a.va, cv.nu, 7.lu, n.cl, p.re, e.km, m.mc, d.hu, ۀ.sl, z.gi, and m.us extracted from files. These domains follow a pattern consistent with XIOC extractor false positives where property access chains are misread as domains (e.g., a.value becoming a.va, 7.luke becoming 7.lu). The file path extracted_from_files is vague and indicates automated extraction without source file context.
The extension has zero malware signature findings and zero obfuscation findings. According to the CVEQ false positive documentation, code-smell findings (23 total) are classified as low severity noise that should never drive a verdict. The two network findings in js/popup.js:35 show standard fetch calls, which are legitimate for a wallpaper extension that needs to load image assets.
The extension's stated purpose—animated live wallpaper featuring anime characters—is a legitimate use case that could reasonably require network calls to fetch wallpaper images. The developer email [email protected] provides attribution, though it's not a verified company name. The small user base (407 users) is consistent with a niche wallpaper extension rather than a mass-deployment malware campaign.
Counterargument: A skeptic might argue that 582 IoC findings is too many to dismiss, and even if some are false positives, genuine malicious domains could be hidden among them. However, if this extension contained real malicious domains, we would expect malware signatures (0 found), obfuscation to hide the malicious code (0 found), and more specific suspicious domains targeting known services like banking or social login pages. The domains listed are generic short strings that match the documented XIOC false positive pattern for property access chains. The complete absence of malware signatures and obfuscation, combined with the extension's legitimate purpose and the known XIOC extractor noise patterns, supports the false positive verdict.
Key Reasons
- Zero malware signatures despite 607 total findings
- Zero obfuscation findings
- IoC domains match XIOC false positive pattern for property access chains
- Extension has legitimate purpose (live wallpaper)
- Code-smell findings are documented noise sources
False Positive Considerations
- XIOC-DOMAIN property access chain false positives
- Code-smell findings (low severity noise)
- Bundled code IoC extraction without file context
Reviewed 2026-05-08; recommended action: suppress false positive; model confidence 75%.
