Users should beware of a new worm on Twitter that posts links on Twitter users’ accounts that redirects them to a fake anti-virus website.
Kaspersky Lab warns users about a new, fast-moving Twitter worm which exploits Google’s goo.gl service of truncated links.
The truncated URLs are lightweight and popularly used in microblogging systems, limiting the length of messages for users of services such as Twitter.
However, shortened links can seriously threaten computer security, because the text of a truncated URL is relatively obscure and a user does not know what it contains prior to ending up on an infected site. Hackers are managing to successfully lure the unwary into using their malicious truncated links.
Worm redirection chain
A recently discovered Twitter worm’s redirection chain pushes users to a webpage that delivers a rogue AV called ’Security Shield’.
Kaspersky Lab malware researcher Nicolas Brulez discovered that once you are on this website, you will receive a warning that your machine is running suspicious applications.
“The warning invites users to remove all the threats from their computer, and download the ‘Security Shield’ rogue AV application. As usual, the result of downloading the program is that the user’s machine is infected with malicious programs,” Brulez said.
