Windows Visual Basic Commandline Compiler DNS Query

The analytic detects instances where `vbc.exe`, the Visual Basic Command Line Compiler, initiates DNS queries. Normally, `vbc.exe` operates locally to compile Visual Basic code and does not require internet access or to perform DNS lookups. Therefore, any observed DNS activity originating from `vbc.exe` is highly suspicious and indicative of potential malicious activity. This behavior often suggests that a malicious payload is masquerading as the legitimate `vbc.exe` process to establish command-and-control (C2) communication, resolve domains for data exfiltration, or download additional stages of malware. Security teams should investigate the process's parent, command-line arguments, and the resolved domains for further indicators of compromise.
