Avengers Infinity War Live Wallpaper

AI Security Review

Evidence context: threat category none; evidence quality moderate.

The "Avengers Infinity War Live Wallpaper" extension (uuid: 9c11ba6a-00d9-5ab0-a730-e1c790b51ddb) shows 232 total findings, but all evidence points to known false positive patterns rather than actual malicious behavior.

IoC Findings Are Extractor Garbage: All 218 IoC findings follow the documented XIOC false positive pattern of property access chains being misidentified as domains. The finding XIOC-DOMAIN-date.now is JavaScript property access, not a domain. Similarly, XIOC-DOMAIN-n.target, XIOC-DOMAIN-ke.td, XIOC-DOMAIN-ce.event.global, XIOC-DOMAIN-f.remove.call, XIOC-DOMAIN-f.teardown.call, XIOC-DOMAIN-c.predispatch.call, XIOC-DOMAIN-this.off, XIOC-DOMAIN-ce.event.handlers.call, XIOC-DOMAIN-ke.th, XIOC-DOMAIN-u.data, and XIOC-DOMAIN-this.show are all property access chains from minified JavaScript being incorrectly parsed as domain names. These match the documented false positive pattern: "Property access chains misread as domains: b.call, h.next, g.id."

No Malware Signatures: The findings_summary shows malware-signature: 0 and malware: 0. There are no actual malware detections, only code-smell findings (14 total) which are documented as noise sources.

No Obfuscation or Network Activity: The findings_summary shows obfuscation: 0 and network: 0. There is no evidence of obfuscated payloads or actual network communications to suspicious domains.

Extension Purpose Is Legitimate: The description states this is a "live wallpaper" for Marvel's Infinity War, which is a legitimate use case for browser extensions. The developer email "[email protected]" is generic but not inherently suspicious for a small wallpaper extension.

Counterargument: A skeptic might argue that the developer using only an email address ("[email protected]") instead of a company name is suspicious, especially combined with 232 total findings. However, the nature of all findings is what matters, not the count. The 218 "medium severity" IoC findings are all documented false positive patterns. The 14 "high severity" findings are code-smell detections which the guidelines explicitly state should NEVER drive a verdict. Generic developer emails are common for small, single-purpose extensions and do not indicate malice without supporting evidence of harmful behavior.

Conclusion: This extension exhibits zero high-confidence threat indicators. All findings are from known false positive sources (XIOC extractor garbage and code-smell rules). The extension provides a legitimate wallpaper function with no evidence of credential theft, browser hijacking, malware delivery, or proxyware behavior.

Key Reasons

• All 218 IoC findings are property access chain false positives
• Zero malware signatures detected
• Zero obfuscation findings
• Zero actual network activity findings
• Extension purpose (live wallpaper) is legitimate

False Positive Considerations

• XIOC property access chain false positives
• Code-smell findings (documented noise)
• IoC count inflation from extractor garbage
