翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク July 2009 cyber attacks ： ウィキペディア英語版 July 2009 cyber attacks The July 2009 cyber attacks were a series of coordinated cyber attacks against major government, news media, and financial websites in South Korea and the United States. The attacks involved the activation of a botnet—a large number of hijacked computers—that maliciously accessed targeted websites with the intention of causing their servers to overload due to the influx of traffic, known as a DDoS attack.〔 Most of the hijacked computers were located in South Korea.〔 The estimated number of the hijacked computers varies widely; around 20,000 according to the South Korean National Intelligence Service, around 50,000 according to Symantec's Security Technology Response group, and more than 166,000 according to a Vietnamese computer security researcher who analyzed the log files of the two servers the attackers controlled. The timing and targeting of the attacks have led to suggestions that they may be from North Korea, although these suggestions have not been substantiated.〔 〕 ==Timeline of attacks== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「July 2009 cyber attacks」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
