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 moderate.

This extension presents 449 total findings, but the nature of these findings indicates false positives rather than malicious behavior. The 432 IoC findings (all medium severity) consist of domains like h.pa, v.va, 3.gl, m.af, jg.mm, 1.ca, c.kr, s.va, u2.vin, 9d.sh, u.so, and 19.cn extracted from files. These short-domain patterns are characteristic of image hosting services or CDN endpoints, which a live wallpaper extension legitimately requires to load anime artwork for the new tab page.

Critically, the evidence shows zero malware signatures, zero obfuscation findings, and zero network findings. The 17 code-smell findings are classified as low severity and match the YARA false-positive patterns documented in CVEQ: these rules fire on basic JavaScript patterns and do not indicate actual vulnerabilities. The absence of obfuscation is particularly significant—malicious extensions almost always employ obfuscation to hide malicious payloads, and this extension shows none.

The extension's stated purpose aligns with its findings: 'Witness Luffy's Pirate King awakening in this epic anime live wallpaper for your Chrome new tab.' A new tab wallpaper extension must load images from external sources, which explains the domain IoCs. The IoC extractor flags these as suspicious because they are external domains, but the domains themselves do not match known malicious patterns (no query., search., or hp.* patterns indicating browser hijacking; no credential-related domains).

The anonymous developer ([email protected]) and low user count (11 users) are legitimate concerns that warrant monitoring, but they do not constitute evidence of malicious behavior. Anonymous publishers are common for hobbyist extensions, and the low user count simply indicates this is a niche anime-themed extension without widespread adoption.

Counterargument: A skeptic would argue that 432 IoC domains represents significant risk and the anonymous developer is a red flag. This argument fails because IoC COUNT is not evidence of malicious behavior—IoC NATURE matters. These domains are extracted from files (likely image URLs embedded in the extension), not observed in actual network traffic. The findings_summary shows "network": 0, meaning no runtime network activity was detected to these domains. Additionally, if this were a malicious extension, we would expect to see malware signatures, obfuscation, or credential theft indicators—none of which appear in this evidence. The zero malware-signature count and zero obfuscation count are strong indicators that this extension contains no hidden malicious payloads.

The recommended action is suppress_false_positive for the IoC findings, as they represent legitimate wallpaper image sources rather than malicious infrastructure.

Key Reasons

  • Zero malware signatures detected
  • Zero obfuscation findings
  • IoC domains are image-hosting patterns, not malicious infrastructure
  • No network findings showing actual traffic to flagged domains
  • Extension purpose (live wallpaper) explains external domain requirements

False Positive Considerations

  • IoC extractor flags image CDN/CDN domains as suspicious
  • Code-smell rules match basic JavaScript patterns
  • High IoC count from bundled image URLs, not malicious traffic

Reviewed 2026-04-29; recommended action: suppress false positive; model confidence 75%.
