What is an SCF file?

An SCF file is a shell command file used by Windows Explorer. Windows Explorer uses SCF files to perform certain actions, such as opening a new Windows Explorer window or showing a user's desktop.

How to open an SCF file

SCF files are not meant to be manually opened. Windows Explorer automatically loads and uses SCF files as needed.

Warning

A vulnerability in SCF files' structure allows cybercriminals to use malicious SCF files to steal a user's Windows login credentials. This attack requires only that a user view the SCF file in a folder or on their desktop. It does not require that the user open the SCF file. Thus, if you notice that you are receiving an untrusted SCF file as part of a download, you should cancel that download or attempt to delete the SCF file without viewing it.
