Publisher Evidence

Limited evidence

[email protected]

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 unknown malware; evidence quality moderate.

This Chrome extension "Minato And Naruto Live Wallpaper" by developer [email protected] presents an ambiguous threat profile. The findings summary shows 698 total findings, dominated by 673 IoC detections and 1 malware signature.

The IoC findings include 11 documented suspicious domains: z.gf, w.pm, d3.pg, 4.jp, t.fr, h.it, i.ck, h.cl, r.ht, x.as, and c.se. These are notably short, unusual domain patterns (1-2 character subdomains with 2-3 character TLDs) that do not match legitimate CDN or infrastructure domains like googleapis.com or cloudflare.com. However, these domains appear in "extracted_from_files" rather than specific code paths, suggesting they may be embedded in a domain list or bundled dependency rather than actively called.

The network finding NET-FETCH-js/popup.js-35 shows a fetch call in js/popup.js:35, which is expected behavior for a wallpaper extension that may need to load content dynamically. There are no findings indicating credential access, session theft, or browser hijacking behavior.

The single malware signature is concerning but lacks context about what specific signature triggered. Critically, there are ZERO obfuscation findings despite the high IoC count. According to the threat model, confirmed malicious extensions typically combine malware signatures with obfuscation AND suspicious domains. The absence of obfuscation weakens the malicious verdict.

The developer attribution ([email protected]) and coherent description suggest a legitimate publisher, not an anonymous actor. The extension's stated purpose (anime live wallpaper) does not align with common malware categories like credential theft or browser hijacking.

Counterargument: A skeptic would argue that 673 IoC findings plus 1 malware signature should trigger a confirmed_malicious verdict. However, the IoC volume is driven by domain list extraction, not active network behavior. The malware signature alone without obfuscation, credential access, or browser hijacking indicators does not meet the threshold for confirmed_malicious per the decision framework. The short domains could be from a bundled ad network or content delivery service for the wallpaper images.

Manual review is needed to determine if these domains are actively contacted or merely embedded in code, and what the malware signature specifically detected.

Key Reasons

  • 673 IoC findings with unusual short domains (z.gf, w.pm, d3.pg, etc.)
  • 1 malware signature detected without context
  • No obfuscation findings despite high IoC count
  • Developer attribution present ([email protected])
  • Extension purpose does not match typical malware categories

False Positive Considerations

  • IoC volume from embedded domain lists rather than active network calls
  • Malware signature without corroborating obfuscation or behavior evidence
  • Bundled dependencies may contribute to finding count
