Twitter virus 'onMouseOver' pinned on 17-year-old Australian and Japanese developer

Yesterday's Twitter "onMouseOver" virus had the social media site aflutter when a bug spread rapidly through users' feeds thanks to a loophole in the site's security.

Although the company said no major damage had come from the virus, it did reveal a major vulnerability and raised fears that another security breach could spread massive damage very quickly.

Now, Mashable reports that the originators of the virus have come forward to claim responsibility. Pearce Delphin, or @zzap on Twitter, tweeted a code with a JavaScript function that other users modified to perform auto retweets and open third-party sites.

Guardian reports that Masato Kinugawa, a Japanese developer, reported the vulnerability to Twitter on Aug. 14, but found the same problem when the new Twitter launched a month later. He created the function to turn tweets different colors.

The most interesting bit about this is how time zones affected the spread of the virus. The virus started in the afternoon in China and spread west as users woke up. It hit Sweden, then Russia, until finally making its way to Twitter headquarters in California. Read the whole story here.
