Which of the following processes should be prioritized for examination during live response?

RpcSs is the Remote Procedure Call Subsystem, a core Windows service expected on every system that provides less actionable forensic value than a user-space application with active external network connections.

chrome.exe is a user-space browser process that maintains active network connections potentially linking to a command-and-control server, and stores credentials, session tokens, and cookies in volatile memory that will be lost on shutdown. Unlike Windows system services, it operates in user context and is a common vector for malicious extensions, injected code, and data exfiltration, making it the highest-value target for immediate live examination.

notepad.exe is a simple text editor with no network capability, making it an unlikely source of active attacker communication or volatile evidence compared to a browser process.

W32Time is the Windows Time synchronization service, a legitimate and expected background process that would not typically surface attacker activity or volatile forensic artifacts during live response.
