Publisher Evidence

Limited evidence

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 weak.

This extension presents a high finding count (487 total) that is almost entirely composed of 471 medium-severity IoC findings from the XIOC extractor. However, the nature of these findings indicates they are false positives rather than genuine threats. The IoC domains detected (k.nr, è.tc, s.st, ۊ.hu, l.mv, h.in, z.ng, famg.iq, 9.mq, a6.ke, 2.kh, y.km) are all extracted from files with generic file_path "extracted_from_files" rather than specific source files, which is characteristic of XIOC extraction artifacts. These short, abbreviated domains with non-Latin characters are typical of property access chains being misread as domains by the extractor.

Critically, there are zero malware signatures, zero obfuscation findings, and zero network findings. The 16 low-severity code-smell findings are expected noise from YARA rules that match basic JavaScript patterns. The extension's stated purpose (anime live wallpaper) does not match the profile of credential theft, browser hijacking, or malware delivery, and there is no evidence in the findings to suggest it performs any of these malicious behaviors.

The anonymous developer ([email protected]) and zero user count are legitimate concerns that warrant caution, but they indicate an unpublished or new extension rather than active malicious behavior. A truly malicious extension would typically show malware signatures, obfuscation, or suspicious network activity—none of which are present here.

Counterargument: A skeptic could argue that the 471 IoC findings represent a sophisticated domain generation algorithm or C2 infrastructure. However, this is not supported by the evidence: the domains lack the pattern of a DGA (they're too varied and include non-Latin characters inconsistently), there are no network findings showing actual connections to these domains, and there's no obfuscation to hide such infrastructure. The XIOC extractor is known to produce massive false-positive volumes from minified JavaScript, and the absence of malware signatures despite 487 findings strongly indicates these are extraction artifacts rather than real threats.

Key Reasons

  • Zero malware signatures despite 487 total findings
  • Zero obfuscation findings
  • Zero network findings showing actual connections
  • IoC domains are XIOC extraction artifacts with generic file paths
  • Code-smell findings are expected YARA noise

False Positive Considerations

  • XIOC extractor domain false positives
  • Code-smell YARA rule noise
  • Generic file_path indicating extraction artifacts
