StalkDaily/Mikeyy continues to flood Twitter
Despite Twitter saying the initial issue with the StalkDaily worm had been resolved, Twitter users are now seeing the effects of a fourth generation of the worm. Now known as the Mikeyy worm, after Mikeyy Mooney, a 17 year old who claimed responsibility, the new worm promotes Mikeyy and taunts Twitter with messages such as "Twitter, hire Mikeyy! (718) 312-8131 :)", "Twitter, your community is going to be mad at you... - Mikeyy" and "This is all Twitters fault! Don't blame Mikeyy!!". Other messages sent by the worm offer instructions on how to remove it but also link to infected user profiles.
The latest variant changes an infected user's name to inject a script element into the head section which directs the browser to include a script called ajax.js from stalkdaily.com. This contains an obfuscated script which will hijack the Twitter account of anyone who visits the user's profile page while logged in to Twitter. F-Secure's blog reports that the latest generation was apparently launched from a freshly registered account "cleaningUpMikey".
Twitter administrators have responded saying they were taking action to block the latest generation of the worm, and The H notes that as of writing, new Mikeyy infected messages seem to be falling off, being replaced with tweets about the worm.
