Fb shuts down malicious fake profiles

 

Malicious fake profiles attacks on Facebook..

  

Facebook on Thursday fended off an attack in which multiple identical profiles were created to spread malware.

 

“Clearly, the Data Snatchers have found a way to automate the creation of Facebook accounts, which means they’ve found a way to bypass the Facebook Captcha,”
Roger Thompson, chief of research at AVG, wrote in a blog post.
Successfully translating a Captcha, a hard-to-read image of letters supposed to ensure that a human is involved, is required for a new account.
 

“We’re looking into how these accounts were created, but it’s very likely that the sign-up process was manual, or that the person behind the attack farmed out the Captchas to be solved by humans for a price,” Axten wrote in an e-mail.

 

For its Captcha system Facebook uses ReCaptcha, “which was recently acquired by Google and is about as well-regarded a Captcha provider as there is,” he said.

 

When the link in the fake Facebook profiles is clicked a fake alert pops up that tries to convince the user that the computer is infected.
