Twitterに対する攻撃の影響

Professor Main Target of Assault on Twitter - The New York Times
twitterだけだと思っていたら、Facebookや他のGoogleサービスも止まっていたみたいですね。
このバックグラウンドにグルジアとロシアの話があるっていうのがゴシップっぽくて面白い。
But Beth Jones, an analyst with the Internet security firm Sophos, said the assault occurred in two stages.
Early Thursday, the attackers sent out a wave of spam under the name Cyxymu, which is a Latin transliteration of the Cyrillic name of the capital of Abkhazia, Sukhumi. This technique, a “joe job,” is intended to discredit a Web user by making him appear to be the source of a large amount of junk e-mail. “These hackers wanted to make him look responsible for millions of spam e-mails,” said Ms. Jones.
The messages contained links to Giorgi’s accounts on several social networks and Web sites, including Twitter.
The next leg of the attack, Ms. Jones said, was a distributed denial of service, or D.D.O.S., attack aimed at knocking Giorgi off the Web. The hackers used a botnet, a network of thousands of malware-infected personal computers, to direct huge amounts of junk traffic to Cyxymu’s pages on Twitter, LiveJournal, YouTube and Facebook in an attempt to disable them, Ms. Jones said.
The junk messages overwhelmed the services, slowing them, and in the case of Twitter and LiveJournal, shutting them down entirely for a time.
攻撃は二回にわたって行われたらしく、
ある一定人物のページを狙いうちした結果、莫大なスパムとトラフィックでサービスが遅くなったっぽいですね。
TwitterとLiveJournalに関しては完全にサービスが止まったそうです。
“I feel a bit ashamed for the people who lost service because my blog was blocked,” said Giorgi.
本人は恐縮しきりの様です。
しかしながら、Twitterの脆弱性もあらわになってしまいました。
The attacks that felled Twitter shed light on the fragility of the popular microblogging service, especially compared to its competitor Facebook, which quickly recovered from the pummeling, said Stefan Tanase, a researcher at Kaspersky Lab, an Internet security firm. Twitter, a small San Francisco company, has been struggling to improve its security even as it tries to manage hypergrowth in the number of users and messages it handles.
SNSに比べ、更新量も多いでしょうし、その更新の即時性、速さがかなり重要になるのでfacebookよりもtwitterはシステム的にサーバーダウンしやすいかもしれません。
あれからTwitterが重いのなんのって。つぶやけるレベルじゃねーぞと。
なかなか面白かったのは次の話。
“If Twitter goes down or shuts down permanently, the conversation just shifts somewhere else,” he said.
ひろゆきとまったく同じこと言ってる。
2chがなくなっても、2chの様なものはなくならない。
それこそが本当にヒトが必要としているものなのかもしれません。
