Cyberpunk 2077 Night City Live Wallpaper New Tab

AI Security Review

Evidence context: threat category none; evidence quality moderate.

This extension provides a Cyberpunk 2077-themed new tab page, a legitimate use case. The 602 IoC findings consist of generic short domains like f.vg, 9.br, s.be, fi.ly, and r.sy. These are characteristic of URL shortener services or CDN infrastructure, not malicious command-and-control servers. The file_path for all IoC findings is "extracted_from_files," indicating these were extracted from bundled code rather than active network destinations.

The 36 malware-signature findings are high-severity YARA matches, but critically there are 0 confirmed malware findings. This pattern—malware-signature without malware—is typical of false positives from bundled npm libraries triggering broad YARA rules. Without specific rule names or file paths, these cannot be confirmed as actual threats. The extension shows 0 obfuscation findings and 0 code-smell findings, which is unusual for genuinely malicious extensions that typically hide their behavior.

The network activity is minimal: only 3 network findings, with one visible fetch call in js/popup.js:29. There is no evidence of browser hijacking (no custom search engines, no history API manipulation), credential theft (no login domain targeting), or data exfiltration (no suspicious external domains). The developer attribution "[email protected]" provides some accountability, though it's an email rather than a verified publisher name.

The strongest counterargument would be that 36 high-severity malware-signature findings should warrant concern. However, the threat model explicitly states that malware-signature findings without confirmed malware detections are often noise from bundled dependencies. The absence of obfuscation, the legitimate extension purpose, and the generic nature of the IoC domains all contradict a malicious intent. If these were real malware signatures, we would expect to see confirmed malware findings, obfuscation techniques, and specific suspicious domains—not 602 generic URL shorteners.

Recommended action is to suppress the false positive, as the findings are driven by known noise patterns rather than actual malicious behavior.

Key Reasons

• 602 IoC findings are generic URL shortener domains, not malicious infrastructure
• 36 malware-signature findings with 0 confirmed malware detections indicates false positives
• No obfuscation or code-smell findings contradicts malicious intent
• Legitimate extension purpose (new tab wallpaper) with minimal network activity
• Developer attribution present via email address

False Positive Considerations

• IoC extractor matching generic URL shortener domains
• Malware-signature YARA rules firing on bundled dependencies
• High finding count from bundled code without malicious behavior
• No obfuscation or confirmed malware despite high signature count
