On Wednesday morning, eBay told its users to change their
passwords. The online auction house and retailer announced in a press release
that it had been hacked. Hackers gained unauthorised access to
a database that included eBay customers' names, home addresses, dates of birth
and encrypted (加密的) passwords, eBay said that financial information like credit
card numbers were stored separately and were not compromised. Encouragingly, the
company said it has seen no fraudulent activity as a result of the
hack. The cyberattack took place between late February and
early March of this year, but eBay only detected it two weeks ago. The company
plans to email customers about the security breach (洞) and tell them to change
their passwords on eBay and any other website where the same password is
used. The compromised passwords were encrypted, so it's unclear
if the hackers are able to read them and use them elsewhere online. The
cyberattack also swept up details like names and addresses, which could
potentially be used to commit fraud outside of eBay. When asked
how many people were affected by the attack, eBay referred the Huffington Post
to a webpage that simply states the company is asking all 145 million of its
active buyers to change their passwords. It's generally good
password hygiene not to use the same password on different websites. But for
eBay customers who have doubled up, the company is recommending you change your
password on both eBay and all other sites where that same password was
used. Cyberattacks can have a chilling effect on online
customers, who must trust retailers with sensitive financial information to do
business. Discount retailer Target has struggled to recover from a data breach
discovered during last year's holiday shopping season, in which the credit card
and debit card records of millions of customers were stolen.
Since December, profits for the retail chain have fallen and its CEO has
resigned. eBay also said that it does not want to speculate on
who committed the attack while it's working with law enforcement.

B.The cyberattack was detected by eBay as soon as it took place two weeks
ago.
C.eBay ensured its customers that their encrypted passwords can not be read

A
【答案解析】[解析] 根据设题按照文章顺序进行的规律将本题出处定位于第3段之后。
第4段最后一句提到，这次计算机攻击也涉及了像姓名和地址这样的详细信息，这些信息可能会在易趣之外被用来诈骗。由此可见，被盗的客户信息可能会被用于某些诈骗行为，故答案为A。由第3段第1句提到的The cyberattack took place between late February and early March of this year, but eBay only detected it two weeks ago. 可以排除B。由第4段第1句提到的the compromised passwords were encrypted, so it's unclear if the hackers are able to read them可以排除C。文中第5段提到，当被问及有多少人受到这次攻击的影响时，易趣并没有正面回答，只是说所有用户都应该更换密码，由此可见，易趣没有具体说明受这次攻击影响的客户人数，故D不符合文意，予以排除。

B
【答案解析】[解析] 根据题干中的Target将本题出处定位于倒数第三段最后一句。
倒数第三段最后一句提到，折扣零售商塔吉特在去年的假日购物季发现，它的数百万顾客的信用卡和借记卡记录被盗，塔吉特为从这次数据漏洞事件中复苏而做出了艰苦的努力。由文中强调的has struggled to recover可以推断，作者引用塔吉特的例子是为了说明数据泄露会对公司造成巨大的影响，B符合作者意图，故为答案。其他三项均属于过度推断，予以排除。
