Findings
Blacklisted network destination: The file references a blacklisted host: api.ipify.org
External process execution: ProcessBuilder can execute operating-system commands.
Minecraft account files collection: Minecraft account files is referenced in a class with file-reading/copying, database-reading or credential-query process calls, directly or through resolved helpers. This is a sensitive-data collection pattern, not proof of exfiltration; legitimate backup or account tools may share it. Argument-level data flow is not proven.
User-Agent: May indicate outbound HTTP requests or client impersonation.
