Globbing is using wildcard characters (asterisks and question marks) to request or evaluate sets of files with the same partial sets of characters. Globbing allows users to expand a search for non-specific file names. The two most common forms of globbing are using a question mark to represent a specific unnamed character in the file and using an asterisk to look for a continuous string of characters. Globbing can be used to search for file content or match filenames.
Hackers may use globbing for denial-of-service (DoS) attacks. Because globbing can require many server resources to look for several different files, creating vague globbing commands can deplete server resources.,
