B  [2015.四川新津中学高三一诊]

   A group of Russian criminals have stolen 1. 2 billion use-rname and password combinations for more than 500 million e-mail addresses. It's the largest known theft on the Inter?net, according to a report of The New York Times.

   Cyber security firm Hold Security discovered the security breach. The firm found that the group of criminals collected personal information from 420， 000 websites, including household names and small Internet sites. The criminals were based in a small city in southern Central Russia. They hacked websites inside Russia as well as big companies in the US and other countries,T/ie New York Times reported.

The criminals found hundreds of thousands of weak web?sites and attacked their coding, Hold Security said. Alex Holden is the chief information security officer of Hold Secur?ity. "The hackers do not just target US companies; they tar?get any website they can get," Holden said. "And most of these sites are still easy to attack.，，

According to Hold Security, the criminals have been using the stolen information to send junk mail through e-mail and on social networks like Twitter. They can also use the 500 million stolen e-mail addresses to plan other crimes. They could use information from bank e-mails to steal your identity or sell the e-mail addresses to other criminals to make quick cash.

The reported break-ins are the latest events to raise doubts about security in big and small companies. Last win?ter, hackers stole 40 million credit card numbers and 70 mil?lion addresses, phone numbers and other personal informa?tion from the retailer Target Corporation. The brand is still working to regain its shoppers' trust.

John Prisco is the CEO of a security firm. He says secur?ity hackings are more common than many people and compa?nies realize. "This issue reminds me of an iceberg, 90% of which is actually under water," Prisco said in an e-mailed statement. So many cyber breaches today are not actually re?ported, because companies are losing information and they are not even aware of it.

Security experts believe hackers will continue breaking into computer networks unless companies become more pro?tective of personal information.
