A 17-year-old Australian student said Wednesday that he is the one who exposed the flaw that led to Tuesday's cross-scripting attack on Twitter.

Pearce Delphin told AFP said he tweeted a piece of the "MouseOver" JavaScript code that prompted pop-up windows when a user hovered their mouse over the content. Unfortunately, this was soon exploited by hackers, who used it to redirect users to adult or dangerous Web sites.

"Is this the point where I mention I need a job? I'm just a poor boy, no body loves me ... except for the media," Delphin tweeted earlier today.

In a Tuesday blog post, Twitter said it actually discovered the flaw that was exploited Tuesday about a month ago and fixed it. A site update unrelated to the new Twitter.com, however, accidentally unleashed it again, and a few people who noticed it took advantage.

"First, someone created an account that exploited the issue by turning tweets different colors and causing a pop-up box with text to appear when someone hovered over the link in the tweet," wrote Bob Lord with Twitter's security team. "Other users took this one step further and added code that caused people to re-tweet the original Tweet without their knowledge."

A Twitter spokeswoman said Wednesday that the company "won't be publicly identifying individuals who may or may not have been involved." Twitter will also not be pursuing legal action, she said.
