Hiyuki Dance of Red Snow (WuWa) Live Wallpaper

AI Security Review

Evidence context: threat category none; evidence quality weak.

This Chrome extensions store listing for a live wallpaper extension was submitted for security review. The analysis examined the extension package contents and all 176 security findings were extracted.

Every single finding is an XIOC domain extraction — there are zero malware signatures, zero network behavior annotations, zero obfuscation detections, and zero code-smell findings. The detected domains (il.wf, ņ97.ne, e.za, u.ky, d-.gi, n.au, o.vi, ow.uz, m.sh, ce.support, ke.th, i.support) are all short, unusual TLD-based fragments. These match the known XIOC garbage pattern: the IoC extractor produces false positives by reading hex substrings from minified JavaScript, JSON blobs, or bundled library code and incorrectly interpreting them as domain names. None of these domains correspond to known command-and-control infrastructure, browser hijack redirect chains, or adware distribution points.

The extension has no developer attribution beyond an email address ([email protected]), no description of functionality, zero users, and was last updated with no changelog. While the empty metadata is unusual, it is not itself evidence of malicious behavior — it is consistent with an extension listing that was published but never actively marketed.

Critically, there are no positive indicators of harm anywhere in the findings: no malware signatures matched, no actual suspicious network endpoints beyond XIOC garbage, no obfuscated payloads, no credential access patterns, and no manifest analysis flags. A verdict of confirmed_risk or confirmed_malicious would require at least one specific positive finding demonstrating harmful behavior, and none exists here. The 176 IoC "findings" are a known artifact of the extraction pipeline, not evidence of real network communication.

Key Reasons

• Zero malware signatures or positive threat indicators discovered
• All 176 IoC findings are XIOC garbage extractions with no real suspicious domains
• No obfuscation, network behavior, manifest flags, or credential access detected
• Extension has no supporting metadata or user base preventing definitive assessment
• No evidence of impersonation, browser hijacking, or data exfiltration

False Positive Considerations

• All 176 findings are XIOC domain extractions typical of false positive hex/fragment parsing from bundled code
• No malware signatures, network findings, obfuscation detections, or code-smell findings present
• Zero users and empty metadata suggest inactive listing rather than active threat
