三 閱讀理解
On the Internet, a packet monkey is someone who intentionally inundates a Web site or network with data packets, resulting in a denial-of-service situation. Packet monkeys typically use tools created and made available on the Internet by hackers. A packet monkey, unlike a script kiddy, leaves no clues as to who is making the exploit, making the identity of a packet monkey more difficult to trace. In addition, a denial-of-service attack can be launched on a wider scale than attacks performed by script kiddies, making them more difficult to investigate. Hackers look down on packet monkeys and often describe them as “bottom feeders.”Because a packet monkey uses tools created by others, the packet monkey has little understanding of the harm that may be caused. Typically, packet monkey exploits are random and without any purpose other than the thrill of making an effect.
