The second worm, which began spreading on Friday ( 6 days after first worm ), referenced Twitter users with a large number of followers (such as @oprah, Oprah Winfrey, and @aplus, Ashton Kutcher). A day later, on Saturday, two more worms appeared, featuring philosophical musings and the word “womp”. The second worm of the day screwed with infected profiles, changing the title of the profile to “Mikey and the Mysterious Treqz”, as explained in a blog post by F-Secure.

The creator of said worms is Mikey Mooney, again! Mikey is 17 years old and claimed responsibility for releasing the first worm, citing boredom. According to Mikey the latest variant aimed to prove that Twitter did not fix the cross site scripting flaw that supposedly was taken care of , according to ZDNet. After releasing the first worm Mikey had landed a job as a web applications developer at exqSoft Solutions. Despite this, Mikey’s latest actions show that outfronting exploits to the community, albeit in a “brute” manner, is still amongst his interests.
