The U.S. government has been hacking Chinese targets that include the nation's mobile-phone companies and one of the country's most prestigious universities, former government contractor Edward Snowden alleged in a series of reports published over the weekend by a Hong Kong newspaper.

前美国政府承包商雇员斯诺登(Edward Snowden)在周末香港某报纸刊发的一系列报道中称，美国政府一直在对中国目标进行网络攻击，其中包括多家移动公司和中国最负盛名的大学之一。

'The NSA does all kinds of things like hack Chinese cellphone companies to steal all of your SMS data,' Mr. Snowden told the South China Morning Post, Hong Kong's leading English-language daily.

斯诺登对香港主要英文日报《南华早报》(South China Morning Post)说，美国国家安全局会做各种事，比如入侵中国手机公司的网络，以便窃取用户的所有短信数据。

Mr. Snowden is believed to be hiding in an unknown location in Hong Kong, where he has been holed up since flying into the city from Hawaii on May 20. While the U.S. has asked that Hong Kong authorities surrender him back home, it is unclear how the government─which maintains an extradition treaty with the U.S.─will respond to such a request. The city's police and chief executive have steadfastly refused to comment on the case.

斯诺登5月20日从夏威夷飞抵香港，据信曾藏身于香港一处不为人知的地方。尽管美国要求香港当局将斯诺登引渡回国，但不清楚香港政府将如何回应这样的请求。香港与美国签订有引渡条约。香港警方和特首对此事一直坚决不予置评。

The SCMP's report didn't give details on how attacks on China's mobile-phone companies may have been conducted but cited mainland cybersecurity experts' concerns that U.S.-made components might make telecommunications equipment vulnerable to so-called 'backdoor' attacks.

《南华早报》的报道没有详细说明针对中国手机公司的网络攻击可能是如何进行的，但报道提到了内地网络安全专家的担忧，他们担心美国制造的组件可能使电信设备容易受到所谓的“后门”攻击。

On Sunday, Chinese official media slammed the U.S. following the latest allegations about U.S. cyber-snooping. 'The United States, which has long been trying to play innocent as a victim of cyber attacks, has turned out to be the biggest villain in our age,' a commentary by Xinhua said.

在有关美国网络监控的最新指控曝光后，中国官方媒体周日强烈抨击了美国。新华社的一篇评论文章说，美国长期以来一直试图扮演网络攻击的无辜受害者，但实际上却是我们这个时代最大的坏蛋。

Meanwhile, according to Mr. Snowden, Beijing's Tsinghua University has been the subject of 'extensive hacking' by the NSA this year, with at least 63 computers and servers attacked during a single day in January. The SCMP's report noted that the university is home to one of the country's largest major backbone networks, the China Education and Research Network─a hub through which the Internet data of millions of Chinese users could be mined, the report said.

与此同时，据斯诺登说，位于北京的清华大学今年一直是美国国家安全局广泛黑客攻击的目标，今年1月的一天就有至少63台电脑和服务器受到攻击。《南华早报》的报道指出，清华大学是中国最大的主要骨干网络之一中国教育和科研计算机网的所在地。报道说，通过中国教育和科研计算机网这个枢纽，可以获取数百万中国用户的互联网数据。

A spokesman for China's Foreign Ministry didn't have an immediate comment on Mr. Snowden's comments, while officials at Tsinghua didn't immediately respond.

中国外交部发言人没有立即对斯诺登的话做出评论，清华大学校方没有立即回复记者的置评请求。

The SCMP also quoted Mr. Snowden as saying that computers at PacNet, a private company that owns fiber-optic networks in the region spanning China, Japan, Korea and Singapore, among other countries, were hacked in 2009 in an operation that has since been shut down. PacNet didn't immediately respond to a request for comment.

《南华早报》还援引斯诺登的话说，2009年，私营公司亚太环通(PacNet)的电脑在一次行动中遭网络攻击，之后该行动停止。亚太环通拥有遍及中国、日本、韩国、新加坡等国的光纤网络。亚太环通没有立即回复记者的置评请求。

This month, the SCMP published additional reports from Mr. Snowden, who accused the NSA of conducting hundreds of cyberattacks in Hong Kong and mainland China since 2009. The city's security secretary said last week that one of the alleged targets, Chinese University, has found no indications that its systems have been breached and that its traffic is continuously monitored around the clock.

本月，《南华早报》刊发了来自斯诺登的更多报告。斯诺登指控美国国家安全局自2009年以来对中国内地和香港进行了数百次的网络攻击。香港保安局局长上周说，被指的目标之一香港中文大学未发现其系统遭到入侵的迹象，其网络流量受到全天候的持续监控。

Hong Kong's justice secretary said last week that the government handles all extradition requests according to its laws. Even if the city does ultimately surrender Mr. Snowden back to the U.S., legal experts have said that if he files for asylum or contests the U.S.'s request, he will likely be able to prolong his stay in Hong Kong for months, if not years.

香港律政司司长上周说，政府会依照香港法律处理一切引渡请求。就算香港最后将斯诺登引渡回美国，法律专家说，如果他申请庇护或对美国的请求提出质疑，他在香港的驻留时间或许能延长几个月，甚至是几年。
