What happened in the DDoS that caused the Twitter outage this week?
While most DoS attacks are designed to take down a specific Web site, Thursday’s DDoS attack targeted someone who has accounts on the different sites–a Georgian blogger, who uses the account name “Cyxymu” and who has accounts on Twitter, Facebook, LiveJournal, and Google’s Blogger and YouTube.The affected companies worked together to investigate the attacks and discovered that Cyxymu was the common thread linking the sites. An investigation is pending into who launched the attack and why.
