Posted: 12/4/2012  |  By: Shara Tibken | CNET
A massive bug swept Tumblr today and infected some of the biggest blogs -- including USA Today, Reuters, The Verge, and CNET -- until Tumblr resolved the issue shortly before 10:30 a.m. PT.
 
GNAA, a hacker group, claimed responsibility for the attack. The group's Twitter profile earlier today said 8,600 unique Tumblr users were affected.
