Thousands of Twitter users are believed to have been hit with malicious links tied to a rogue antivirus scam circulating the microblog service.
The scam is spreading through malicious links abusing the goo.gl URL shortening service. According to Kaspersky Lab, the malicious links redirect users to different domains with an "m28sx.html" page. That HTML page redirects users to a static domain with a Ukrainian top-level domain. From there, blogged Kaspersky Lab Senior Malware Researcher Nicolas Brulez, the domain redirects the user to an IP address pushing fake antivirus.
"Once you are on this website," Brulez blogged, "you will get [a] warning that your machine is running suspicious applications and you are encouraged to scan it. … The user is invited to remove all the threats from their computer, and will download a fake Anti Virus [sic] application called 'Security Shield.'"
Del Harvey, director of Trust and Safety for Twitter, tweeted during the day that the company was working to remove the malicious links and reset passwords on compromised accounts.
