Publisher Evidence

AWS

Publisher identity, store signals, distribution reach, and warning signals used for context. Treat this as supporting evidence, not a clean bill of health.

Firefox 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 moderate.

The extension 'AWS Lab Maker' has a high number of IoC findings, with 600 medium-severity IoC findings detected by XIOC. However, upon closer inspection, these findings appear to be related to the extension's functionality, which involves generating personalized hands-on labs for AWS services with AI-powered guidance. The network findings, such as 'NET-SOCKET_IO-chunks/router-CS1mzAfL.js-1' and 'NET-FETCH-chunks/useSubtitles-D9vAI-Yh.js-312', suggest that the extension is making network calls to facilitate its functionality. Despite the high number of IoC findings, there is no evidence of malicious behavior, such as malware signatures or obfuscation. A potential counterargument to this verdict could be that the extension's lack of developer name and high number of IoC findings could indicate a potential security risk. However, given the extension's functionality and the nature of the findings, it is likely that the findings are related to the extension's legitimate functionality. Therefore, the verdict is likely_false_positive.

Key Reasons

  • High number of IoC findings related to extension functionality
  • No evidence of malicious behavior, such as malware signatures or obfuscation
  • Network findings suggest legitimate functionality

False Positive Considerations

  • IoC extractor garbage
  • High finding count driven by XIOC extractor

Reviewed 2026-05-31; recommended action: suppress false positive; model confidence 80%.
