Ongoing problems at Twitter.
Twitter administrators don't seem to be able to shut down the various XSS / CSRF worms that have been plaguing the service over the weekend. Latest round of worms just started minutes ago. Apparently this run was started by a freshly registered user called cleaningUpMikey:
If you clicked on the name or the image of the person sending the message, you would get infected as well and would send the same message - and anyone viewing your profile would do the same.
We can't confirm whether "Mikeyy" is really behind these attacks. We can't confirm the above phone number either. However, it was likely picked up from this page from a social networking site:
For now, don't view profiles in Twitter.
Updated to add:
A quick look at another incarnation of the same worm. This one was interesting, as it was using bit.ly redirector in the messages.
Infected users were sending Tweets like this: "How TO remove new Mikeyy worm! RT!! http://bit.ly/yCL1S"
A message like this is particularily nasty, as there were plenty of re-tweets of this malicious message sent by genuine users.
The bit.ly link got redirected back to Twitter, to user reberbrerber's profile. Which would infect Twitter users who would view it.
