问题    What has been described as the largest ever ransomware attack—a cyber criminal scheme that locks up computer files until victims pay a ransom—holds the paradoxical distinction of being both an outrageous success (in terms of its blast radius) as well as an abject failure (in terms of its haul). The malicious software spread so far and wide, jammed up so many IT networks and generated so much panic and chaos that the wrongdoers effectively undid themselves.
   On May 12, the world awoke to the beginnings of hundreds of thousands of old Microsoft Windows based computers’ seizing up as they subjected to a malicious software, appropriately called WannaCry. Within hours, the digital epidemic circled the globe like the Spanish flu, infecting machines running outdated operating systems in some 150 countries, spreading across numerous homes and corporate networks. The attack, which relied on powerful tools believed to have been developed by the NSA and leaked online in April by a group of hackers known as the Shadow Brokers, wormed its way through businesses, hospitals and governments, all of which found themselves suddenly locked out of their own systems.
   Researchers detected the wave quickly, and it wasn’t long before they picked up on the criminals’ self-defeating mistakes. The attackers failed to assign each victim a separate Bitcoin wallet , researchers noted, a critical error that meant they would not be able to easily track ransom payments. They neglected to automate the money collection in a way that would scale. And then there was the matter of the kill switch.
   No one is quite certain why the attackers coded a self-destruct button into their software, yet that’s precisely what they did. Marcus Hutchins, a 22-year-old security researcher based in England who goes by MalwareTech, stumbled on the power plug largely by accident. After taking lunch on that Friday afternoon, he inspected the malware and noticed a specific web address encoded within. Curious, he registered the domain for less than $ 11. This simple act stopped the malware, killing the virus’ ability to spread and buying time for organizations to upgrade their software and deploy protections.
The most suitable title for the text is______.

选项 A、An Unsuccessful Malware Attack
B、Cyber Crime: Hard to Prevent
C、A Widespread Computer Virus
D、WannaCry: New Malicious Software

答案A

解析 主旨题。本题需综合各段首句。第一段首句提到ransomware attack,an abject failure 等关键词;第二段首句提到malicious software,WannaCry等关键词;第三段首句出现the criminals’self-defeating mistakes这一关键词:第四段首句出现the attackers,self-destruct button等关键词。文章讨论WannaCry恶意软件攻击,从首段就指出它既是一次成功,也是一次失败,尤其第三、四段着重讨论该软件的缺陷,其中abject failure,self-defeating mistakes,self-destruct都是明显提示。故[A]与原文主旨最接近,其中unsuccessful=failure,self-defeating mistakes,self-destruct等词。选项[B]cyber crime强调“网络犯罪”,而非“恶意软件”,故排除。选项[C]computer virus强调“电脑病毒”,[D]malicious software强调“恶意软件”,但都没体现failure这一关键词,故排除。综上,[A]为本题答案。
