Findings
Bombay signature: Bombay-associated Java loader: a method constructs and starts PowerShell to download and execute a script from tools.lumma.cy. The next-stage malware is not included in this identification.
PowerShell download and execution: The method constructs a PowerShell process with a remote download piped to Invoke-Expression and calls ProcessBuilder.start. The downloaded payload is not analyzed.
Bundled native library: The archive contains code that runs outside the JVM sandbox.
External process execution: ProcessBuilder can execute operating-system commands.
PowerShell execution: The file references PowerShell execution.
Native library loading: The class invokes a JVM API that loads platform-native code.
