Image-based bulletin board 4chan, reportedly used as a forum by the hacker group Anonymous, succumbed Tuesday to a distributed denial-of-service (DDoS) attack, according to the site's founder, Chris Poole.
The average size of distributed denial-of-service (DDoS) attacks have weighed in at 20 percent higher so far this year than they did in 2012, according to statistics released Monday by security firm Arbor Networks.
Twitter was knocked offline again on Tuesday, the second prolonged outage affecting the popular microblogging site in less than a week. The company did not immediately know the cause of the latest service interruption, only stating in its Status blog that, "We're back up and analyzing the traffic data to determine the nature of this attack." The site was down for about 20 minutes on Tuesday, starting around 3 p.m. EST. Last week's downtime, which lasted a couple of hours, was traced to distributed denial-of-service attacks launched against the Twitter account of a pro-Georgian blogger. Facebook and LiveJournal also were hit but did not sustain any significant downtime. — DK
