@DGabri @MatteoBiscosi This work is broken, not glued with the documentation, untested. Not a great job by both of you.

Example
MALICIOUS JA3

• Description: This risk indicates a detection of a malicious Java Application (Java 3) in the monitored network.
• Possible attacks: The presence of this application can signal various threats such as code injection, data theft, or unauthorized access due to its outdated nature and known vulnerabilities. It may also serve
  as a vector for malware distribution.
• Remediation: To secure the network when this risk is detected:
  1. Isolate any devices running Java 3 applications immediately to prevent further potential damage or spread of threats.
  2. Apply updates for the Java Application as soon as possible to patch known vulnerabilities and improve security.
  3. Implement strict access controls and whitelist trusted applications on the network.
  4. Monitor network traffic closely for any unusual activity related to Java 3 and take appropriate action if necessary.
  5. Regularly scan devices for malware and ensure that antivirus software is up-to-date and functioning properly.
