"The exploit's link -- http://tinyurl.com/amgzs6 -- relied on an
obscured URL from the TinyURL link-shortening service. The hack was
shut down early this afternoon by TinyURL's founder, Kevin
Gilbertson, after Twitter users notified him of the attack.
""On my end, I just got some e-mails mentioning it. So once I
found that out, I terminated the URL like I do with other abuse
instances," Gilbertson told InternetNews.com. He added that he
replaced the forward of the URL with a notice that the URL had been
terminated and an explanation of TinyURL's terms of service.
"Before the link was blocked, however, it managed to place a
major strain on Twitter's infrastructure. At several points,
visitors to the service's Web site were greeted by a page saying
that the site was over its message capacity. Twitter spokespeople
did not return requests for comment."
