I got an aix file on an unknown website on the Internet, I can't be sure if this website and the aix file are safe, is there any way or tool to scan the aix file to make sure it doesn't leave a back or Trojan in the software, or steal user data?

Get your extensions from a reliable source. Generally, if posted on one of the main AI2 communities (AppInventor/Kodular/Niotron/AppBuilder) extension developers would be very foolish to post any extensions with viruses or trojans on those platforms.

Check the extension developer out, any comments on the communities about their extensions that might raise a concern.

Because advanced users would check that the extension is malicious and write about it? How would they check that?

For example:

Android App Calling Home Check

Detecting if an Android app is "phoning home" involves identifying whether the app is sending data to external servers, often without explicit user consent.

  • Use Network Monitoring Tools: Apps like NetGuard (firewall) or Packet Capture (Wireshark) can monitor real-time network traffic to detect outgoing connections from apps.
  • Check App Permissions: Review the app's permissions in Settings > Apps > [App Name] > Permissions. Look for unusual permissions like "Internet access", "Network state", or "Phone state" that may indicate data transmission.
  • Use Developer Tools: In Developer Options, enable "Show CPU usage" and "Network usage" to observe background data activity.
  • Check for Suspicious Behavior: Apps that send data during idle times, use excessive bandwidth, or connect to unknown domains may be "phoning home."
  • Third-Party Analysis: Tools like VirusTotal or Google Play Protect can scan apps for malicious behavior, including data exfiltration.

Note: There is no built-in Android API to definitively confirm if an app is "phoning home" without external monitoring. The behavior must be inferred from network activity and permissions.

There are also anti-virus apps that can check your app.
