New Twitter Worm on the loose, don’t click suspicious links. Details here.

Updates at the foot of the post.

There’s a worm spreading rapidly across twitter. It appears to be a tweet with no text but just a URL. A twitter search highlights the extent of the problem.

New York, are you ready?

We’re building Momentum: an all killer, no filler event this November.

The URL appears to be identical: on every tweet but it’s highly likely that it will alter itself at some point.

What we’ve been able to learn is that the worm seems to be either creating or using a number of spam/newer accounts – that said a few influentials have also tweeted the URL. The results of the search only go back about 6 hours, so it hasn’t been around that long and appears to stem from

More interesting is this screenshot from a tool that lets you check the full URLs behind short ones. It apparently redirects to Very odd.

Tried this on a secondary Linux machine. Not sure what was supposed to happen.

Just found the easiest way to track who follows and unfollows you –

We have spoken with the developers at Fllwrs and have been assured that the tweet was a by-product of code used for testing purposes and has now been resolved. The service is not malicious, it just sent out a lot of automated messages recommending people to use the service.

Remember, if you have think your Twitter account may have been compromised by a service, you should head to and revoke its access.

To do this, head into: Settings -> Connections -> Find the app and REVOKE ACCESS!
