What’s whoami.exe (whoami - displays logged on user information)? Is it safe or a virus?

The whoami.exe tool is a command-line utility included in Microsoft Windows that is used to display the current username and the security groups the user belongs to.

When executed, the whoami.exe command retrieves and displays the user's security identifier (SID), username, group membership, and other relevant information. This allows users, administrators, and system processes to easily ascertain the current user's identity and permissions, which can be useful for troubleshooting, access control, and system administration tasks.

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable?
