结构: Simple

Abstraction: Base

状态: Incomplete

被利用可能性: unkown

基本描述

The software contains code that is designed to disrupt the legitimate operation of the software (or its environment) when a certain time passes, or when a certain logical condition is met.

示例代码

例

Typical examples of triggers include system date or time mechanisms, random number generators, and counters that wait for an opportunity to launch their payload. When triggered, a time-bomb may deny service by crashing the system, deleting files, or degrading system response-time.
