计算机病毒和网络蠕虫通过一系列不断的创新而发展，导致了最近一波快速传播和危险的蠕虫。回顾其历史发展和最近爆发的情况，可以得出一些看法。首先，虽然最初病毒比蠕虫更常见，但近年来蠕虫已成为主要威胁，与计算机网络的增长相吻合。其次，尽管防火墙和其他网络安全设备得到了广泛使用，但蠕虫病毒的爆发仍在发生，并可能在不久的将来继续构成威胁。第三，最近出现的蠕虫病毒是一系列快速连续的变种。与早期病毒的独立工作不同，这些变种表明蠕虫创建者之间的协调程度越来越高。第四，最近的蠕虫已经显示出传播速度更快和利用更多感染媒介的能力。这一趋势意味着更加迫切地需要采取自动化、协调一致的保护措施。最后，更危险的有效载荷正变得司空见惯。这表明蠕虫创建者使用蠕虫的目的不仅仅是感染，例如数据窃取和设置拒绝服务网络。
Computer viruses and network worms have evolved through a continuous series of innovations, leading to the recent wave of fast-spreading and dangerous worms. A review of their historical development and recent outbreaks leads to a number of observations. First, while viruses were more common than worms initially, worms have become the predominant threat in recent years, coinciding with the growth of computer networking. Second, despite widespread use of firewalls and other network security equipment, worm outbreaks still occur and will likely continue to be a threat for the near future. Third, recent worms are appearing as a series of quick successive variants. Unlike the independent efforts of early viruses, these variants suggest an increasing level of coordination among worm creators. Fourth, recent worms have shown capabilities to spread faster and exploit more infection vectors. This trend implies a more urgent need for automated, coordinated protection measures. Finally, more dangerous payloads are becoming commonplace. This suggests that worm creators are using worms for other objectives than simply infection, such as data theft and setting up denial of service networks.
