What malicious activity is triggered at a specific time to cause harm?

A logic bomb is a type of malicious code that is specifically designed to execute when certain conditions are met, often related to time or specific events. For instance, it may be programmed to run on a particular date or when a certain operation occurs, such as opening a file or reaching a certain condition within a system. This advantageously allows the attacker to inflict damage at a strategic moment, making it difficult for defenses to predict or prevent the attack.

In contrast, ransomware is a type of malware primarily aimed at encrypting a victim's files and demanding a ransom for the decryption key, but it does not inherently have a time-based trigger. Worms are self-replicating malware that spread across networks without human intervention, and they do not rely on specific conditions to execute. Trojan horses masquerade as legitimate software to trick users into installing them, but they also do not have a built-in time-triggered element. Thus, the logic bomb is distinct in its utilization of timed execution to carry out malicious activities.
