AI Security Report

AI Security Review

Risky Plugins reviewed this extension with an AI-assisted security workflow on 2026-04-21. The review verdict is benign but powerful with 80% confidence.

Recommended action: no action.
Risk context: MEDIUM risk, score 62/100.
Evidence context: threat category none; evidence quality moderate.

The "Jam-Ya Auto Fade" extension (v2.4.0) published by [email protected] exhibits no detectable security threats based on the provided evidence. The findings_by_category object is entirely empty, confirming no code-smell rules (e.g., postinstall, credential access), IoC matches, or obfuscation patterns were triggered during analysis. The extension's description explicitly states it uses the Spotify API for auto-fade functionality without DOM manipulation, which aligns with benign behavior for audio customization tools.

The developer's use of a Gmail address is common for independent developers and does not inherently indicate malicious intent. While the extension has only 1 user, low adoption alone does not correlate with malice, particularly for niche utilities targeting specific platforms like Spotify. No typosquatting or impersonation of known extensions (e.g., Spotify's official tools) was detected, and the name "Jam-Ya Auto Fade" does not mimic popular extensions.

The strongest counterargument is the combination of an anonymous developer and minimal user base, which could signal a throwaway project. However, the absence of any malicious indicators—such as credential access, suspicious domains, or obfuscated payloads—overrides this concern. The extension's declared purpose (Spotify API integration) is consistent with its metadata, and no evidence suggests hidden functionality.

The analysis confirms no evidence of high-confidence threats: no browser hijacking (no custom search domains), no credential theft (no login domain IoCs), no malware delivery (no Flash/VPN lures), and no proxyware behavior. The absence of findings in dist/ or bundle files rules out multiplicative false positives from bundled dependencies. Zero-width Unicode characters in locale files (a known false positive) were not detected, as no locale files were flagged.

The extension's functionality (Spotify API integration) is legitimate and does not require elevated permissions that could enable misuse. While API access could theoretically be misused, the lack of obfuscation or suspicious network activity negates this risk. Given the lack of findings and alignment with legitimate use cases, this extension is classified as benign but powerful due to its API access. No action is required, though monitoring for future updates is prudent.

Key Reasons

  • No findings in any category
  • Legitimate Spotify API usage described
  • Low user count but no malicious indicators

False Positive Considerations

  • None detected
