A global cyberattack, which is considered the biggest cyberattack ever, is spreading quickly and widely.
What the attack does
Cyber bad guys have spread ransomware(勒索软件), known as WannaCry, to computers around the world. It locks down all the files on an infected computer. The hackers then demand $300 in order to release control of the files.
How it happened
WannaCry takes advantage of a vulnerability(弱点) in Microsoft Windows. Microsoft released a security patch for the vulnerabilities in Marclf. Playing with fire finally caught up with the victims.
Microsoft requires Windows 10 customers to automatically update their computers, but some people with older PCs disabled automatic updates.
The attack has been found in 150 countries, affecting 200,000 computers, according to Europol, the European law enforcement agency. FedEx, Nissan, and the United Kingdom's National Health Service were among the victims. In the U.K., hospitals were crippled by the cyberattack, which forced operations to be canceled and ambulances to be diverted.
Who is vulnerable
Microsoft said it had taken the "highly unusual step" of releasing a patch for computers running older operating systems including Windows XP, Windows 8 and Windows Server 2003. So even people with older computers should update them.
Apple's Mac computers were not targeted by this ransomware attack. Bad guys generally target Windows far more than Apple's operating system because there are vastly more computers running Windows around the world.
A. When it will be solved
B. How widespread the damage is
C. That's why it's called ransomware.
D. The hackers remain anonymous for now.
E. Here is a super-simple explanation of what's going on.
F. Anyone who hasn't updated their windows PC recently is easy to attack.
G. But many corporations don't automatically update their systems.
根据短文内容,从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Most drinks stating that they are fruit-flavored (水果味道的) contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission.
“Shoppers need to check the labels (标签) before buying drinks, though sometimes the actual content can be non-existent,” said Food Commission spokesperson Ian Tokelove. “Food production is highly competitive. {#blank#}1{#/blank#} It will increase profits, and consumers won't always realize they are being tricked.”
Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors. Researchers analyzed the contents of 28 strawberry-flavored products sold in stores. {#blank#}2{#/blank#} Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit. In addition, each juice box contained nearly eight teaspoons of sugar.
{#blank#}3{#/blank#} Let's take jam as an example. Some strawberry-flavored jam was labeled as containing no artificial colors, flavors, or sweeteners, but it contained absolutely no strawberries at all.
{#blank#}4{#/blank#} Consumers have the rights to know clearly about what they have bought. Under current UK law, food packages do not have to distinguish between natural and artificial flavoring. “Describing a product as strawberry flavor and covering the surface of the packet with pictures of strawberries is misleading. {#blank#}5{#/blank#} Unfortunatly, it is also legal and widespread,” Tokelove said. “It's time to take measures to protect the consumers' rights.”
A. The products which contain real fruit are popular with people. B. Even products advertised as more natural often contained no fruit. C. They found that about 60 percent of them didn't contain any fruit at all. D. If companies can cut their costs by using flavoring, they are likely to do so. E. It is important and necessary to demand a small amount of flavoring in the products. F. Actually the product contains just a tiny percentage of strawberry or even no fruit at all. G. The Food Commission suggested all flavors used in a product should be listed on the packaging. |
