編程網站Github遭遇網絡攻擊
Github, an online forum for software developers that also hosts tools used by Chinese internet users to bypass censorship, has been hit by a powerful cyber attack that security experts believe originated in China.
軟件開發人員在線論壇網站Github遭遇強勁網絡攻擊，安全專家相信這次網絡攻擊源自中國。目前，Github網站上託管着中國互聯網用戶可用來繞開中國國內審查機制的工具軟件。
The San Francisco-based start-up said it was experiencing the largest denial-of-service attack in its history, as cyber criminals bombarded the site with traffic in an attempt to take it offline.
這家總部駐舊金山的初創公司表示，該網站正經歷建站以來最大規模的“拒絕服務”(DoS)攻擊。所謂拒絕服務攻擊，是指網絡罪犯通過巨大的流量轟炸某個特定網站，以使其下線的網絡攻擊方法。In a blog post, the company said the attack had started on Thursday and involved a “wide combination of attack vectors”, including “sophisticated new techniques that use the web browsers of unsuspecting, uninvolved people to flood with high levels of traffic”.
該公司在一篇博客文章中表示，這次網絡攻擊始於週四，“參與的攻擊媒介涵蓋範圍極廣”，使用了“十分複雜的新技術，通過受信任的無辜人羣的網絡瀏覽器，以極高流量水平衝擊了網站”。
The company said that based on reports it had received, “we believe the intent of this attack is to convince us to remove a specific class of content”.
該公司表示，根據它已收到的相關報告，“我們相信此次攻擊的意圖是說服我們移除特定類別的內容”。The privately owned company would not specify what content was being targeted. The site is mainly used by software engineers and start-ups to store and collaborate on their work.
這傢俬人控股的公司不會透露具體要求移除的內容是什麼。目前，使用該網站的主要是軟件工程師和初創企業，他們用它存儲其工作內容並開展相互合作。But it also contains copies of some websites banned in China, including a page run by that helps Chinese internet users circumvent government censorship.
不過，該網站還託管着部分中國被封網站的拷貝，其中包括網站運營的一個網頁。是一家幫助中國互聯網用戶繞開政府審查機制的網站。Security experts said the attack appeared to have originated in China, with the web browsers of foreign visitors to , the Chinese search engine, stealthily redirected to Github, overwhelming the site with traffic.
多名安全專家表示，此次攻擊似乎源自中國，中國搜索引擎百度網站()的外國訪問者的瀏覽器被隱祕地重定向至Github網站，從而令該網站的流量超過其承受能力。Github was temporarily blocked in China in 2013.
2013年，Github網站在中國曾被臨時封禁。Adam Fisk of , a site that provides tools for bypassing China’s “Great Firewall” and hosts its installers on Github, said this kind of DDOS attack could cost a company hundreds of thousands of dollars a day, and might be aimed at putting pressure on Github to take down content that could not be blocked wholesale because Github is widely used by China’s technology industry.
網站的亞當•菲斯克(Adam Fisk)表示，這種分佈式拒絕服務攻擊(DDoS)一天就會令企業蒙受數十萬美元損失。採取這種攻擊方式可能旨在向Github施加壓力，迫使該網站取下無法被封禁的內容。由於中國高科技產業也在廣泛使用Github網站，從整體上將該網站封禁並不可行。“Github is hugely important to the whole internet, it’s where everyone keeps their code,” Mr Fisk said. “The more disturbing strategy shift this represents is that the Chinese are going after sites such as Github not through blocking but through denial of service attacks. It seems like what they are doing is trying to bend Github to their will, to intimidate them.”
菲斯克表示：“Github對整個互聯網都至關重要，所有人都把代碼放在該網站上。這次攻擊顯示出，中國人正通過拒絕服務實施攻擊而不是封禁對付這類網站，從而將其策略轉向更偏重擾亂對方運作的方式。他們的目的看起來似乎是試圖恐嚇Github網站，以便讓該網站按照他們的意志行事。”Github has managed to keep much of the site live during the attack. It has published regular status updates showing the attention of the hackers switching between different parts of the forum and the highest levels of traffic flooding the system in waves.
在此次攻擊期間，Github成功地保持了網站大部分內容的運作。該網站發佈了一份例行狀態更新，顯示出黑客的注意力在網站不同部分間不斷轉移，衝擊其系統的最高流量水平也時高時低。The US has accused the Chinese People’s Liberation Army of hacking into American websites, with the FBI recently investigating an attack on , which manages website addresses, according to people familiar with the probe. The Chinese military denies the accusation and insists it is a victim in the recent global surge in cyber warfare.
美國曾指控中國人民解放軍(PLA)攻擊美國網站。知情人士表示，美國聯邦調查局(FBI)最近曾對管理網址的網站遭遇的網絡攻擊開展過調查。中國軍方否認了這一指控，堅稱他們是近期全球網絡戰激增的受害者。
