Security Alert: Twitter virus spreading.- From AVG


Security Alert: Twitter virus spreading.

A new virus labelled the “Tweet Viewer” virus has been spreading on the popular social networking platform Twitter.
The virus, which emulates similar viruses on Facebook, encourage a user to follow a link which will allegedly show them who has recently viewed their profile. They normally encourage users to click by promising to reveal “shocking” truth over who looks at your profile, and many use ex-partners as lures.
While the virus has already been well documented and Twitter security has already released a recommended course of action to avoid falling victim to such attacks and also what to do if you already have.
As ever it is important to make sure you trust any link you follow on social networking sites where malicious intent is rife due to the high trust environment. We would recommend only following a link if you implicitly trust the sender and it is addressed to you specifically.
If you’re still not entirely sure about a link try and use a Link Scanner where possible, this should be able to check for attacks before you become vulnerable. AVG has a free Link Scanner which you can use any time here.
Further information about the Tweet Viewer virus can be found here.

I just viewed my TOP20 Profile STALKERS. I can’t believe my EX is still checking me every day –http://bit.ly/tweetviewer
There is something amazing about how desperately humans want to see who has viewed their online profiles. This desire has been taken advantage of (again) by Twitter spammers as tweets like “WOW! You can see WHO VISITS your TWITTER profile. That’s cool! 🙂 – http://bit.ly/tweetviewer” and “I just viewed my TOP20 Profile STALKERS. I can’t believe my EX is still checking me every day” are proliferating this morning, at about 159 tweets a minute.
The “See Who Viewed Your Profile” application preys upon this exact curiosity, asking users for Twitter oAuth, and then using that authorization to tweet out the above. And while it’s not clear that it’s doing anything behind the scenes, at the moment it is definitely using the access granted to spread itself. Once again: Don’t click on any http://bit.ly/tweetviewer links, and if you do, immediately revoke the application’s access to your account by going to Settings > Connections > Revoke Access.
Twitter’s Head of Trust and Safety Del Harvey recommends the same, here.

If you clicked (even though you knew the link was bogus), you gotta revoke access to the app. Help page:http://t.co/TjSCpcL

Access revoked, password changed. Damn iPhone usage of Twitter. Clicked on a link before I knew what it was. #fawk
Update: Bit.ly has blocked the domains hosting the links, but as long as the app has Twitter permissions it continue to spread with a new short link. Here are the Bit.ly stats of the originallink’s trajectory.
