A script file is a plain text file containing a series of commands or instructions written in a scripting language, such as Bash, Python, or PowerShell. These files are used to automate repetitive tasks, execute system commands, or run programs without manual intervention. In cybersecurity, script files can be used for legitimate administrative purposes or, if misused, to launch automated attacks, deploy malware, or exploit vulnerabilities. Proper handling and monitoring of script files are crucial for maintaining system security and preventing unauthorized actions.
