English英语译成Chinese汉语 技术/工程设计 IT（信息技术） security threats

Zeus is a prime example of this specialization. The banking Trojan, which spreads via phishing and drive-by download attacks from legitimate sites, has an ecosystem of underground programmers who create spam campaign templates that plug into Zeus and ***exploit kits*** that capitalize on specific vulnerabilities. Criminals can buy one exploit kit to attack computers running Mozilla's Firefox and another to attack Adobe Acrobat vulnerabilities. Zeus' openness has driven its popularity and dramatic increases in functionality. More than 90,000 variants of it now exist, according to Symantec.
