Visitors to top porn sites hit by malvertising attack

In the latest attack involving malicious advertisements, hackers managed to launch Flash Player exploits against the visitors of several popular porn websites.

It’s not clear how many users were impacted, but the affected websites have over 250 million monthly visits combined, according to researchers from Malwarebytes who spotted and analyzed the attack.

The malicious ads were posted through an advertising network called AdXpansion that was abused in similar incidents in the past.

The attackers managed to distribute through the network a Flash-based ad that attempted to exploit a vulnerability in Flash Player.

The flaw affects Flash Player through version 17.0.0.134, which was released within the last two months, the Malwarebytes researchers said in a blog post Thursday. Affected sites listed in the blog post include Drtuber.com, Nuvid.com, Hardsextube.com and Justporno.tv.
