A logic bomb is a type of malware that executes malicious code when certain conditions are met. A logic bomb can be triggered by various events, such as a specific date or time, a user action, a system configuration change, or a command from an attacker. A logic bomb can perform various malicious actions, such as deleting files, encrypting data, displaying messages, or launching other malware.
The snippet of Python code shows a logic bomb that executes a function called delete_all_files() when the current date is December 25th. The code uses the datetime module to get the current date and compare it with a predefined date object. If the condition is true, the code calls the delete_all_files() function, which presumably deletes all files on the system.
