SAN FRANCISCO—The attack had the hallmarks of something researchers had dreaded for years: malicious software using artificial intelligence that could lead to a new digital arms race in which A.I.-driven defenses battled A.I.-driven offenses while humans watched from the sidelines.
But what was not as widely predicted was that one of the earliest instances of that sort of mal-ware was found in India, not in a sophisticated British banking system or a government network in the United States. As India rushes to go online, it provides a fertile testing ground for hackers trying their skills in an environment where they can evade detection before deploying them against a company or state that has more advanced defenses. The cyberattack in India used malware that could learn as it was spreading, and altered its methods to stay in the system for as long as possible. Those were "early indicators" of A.I., according to the cybersecurity company Darktrace. Essentially, the malware could figure out its surroundings and mimic the behavior of the system’s users, though Darktrace said the firm had found the program before it could do any damage.
At times, these attacks are simply targeting more susceptible victims. While companies in the United States will often employ half a dozen security firms’ products as defensive measures, a similar company elsewhere may have just one line of defense—if any. In the case of attacks carried out by a nation-state, companies in the United States can hope to receive a warning or assistance from the federal government, while companies elsewhere will often be left to fend for themselves.
Cybersecurity experts now speculate that a February 2016 attack on the central bank of Bangladesh was a precursor to similar attacks on banks in Vietnam and Ecuador. That hackers managed to steal $81 million from the Bangladesh Bank generated headlines because of the size of the heist. But what interested cybersecurity experts was that attackers had taken advantage of a previously unexplored weakness in the bank’ s computers by undermining its accounts on Swift, the international money transfer system that banks use to move billions of dollars among themselves each day.
The following are the characteristics of malware used in cyberattack in India EXCEPT that______.
选项
A、it is not a full-fledged A.I.-driven piece of software
B、it can copy the action of the users to blend in
C、it can learn while it was in the system
D、it changes ways to remain undetected for as long as possible
答案
A
解析
细节题。根据题干关键词定位到文章第二段。B项“模仿用户的行为以蒙混过关”与第二段末句中…mimic the behavior of the system’s users表述一致,其中B项中的copy是mimic的同义替换。C项“侵入系统后进行了自我学习”和D项“改变方法让自己尽可能长时间地不被发现”可从…could learn as it was spreading,and altered its methods to stay in the system for as long as possible中找到相关信息。A项“一个不完全由人工智能主导的软件”并未在原文中提及,故本题选A。
