Researchers at Malwarebytes have identified an attack campaign believed to be exploiting a vulnerability in a WordPress plugin. During the past few days, Malwarebytes detected multiple WordPress sites injected with a malicious iframe. The iframe redirects victims to a phony version of The Pirate Bay site. Once there, victims are served the Nuclear exploit kit via a drive-by download attack. "This exploit kit targets most browser plugins but it focuses in particular on the Flash Player which was affected by no less than three zero days in the span of a month," said Jerome Segura, senior security researcher at Malwarebytes Labs. According to Segura, Malwarebytes does not have the exact numbers of how many sites are impacted. However, he said the attack appears to be a specific or targeted campaign. As of this afternoon, the phony site is still up. "And I can add something that I didn't mention originally, in that the site does not index real torrent results but rather pushes a program, maybe to collect affiliate kickbacks," he said. "We believe it has to do with a WordPress plugin rather than the CMS itself," Segura noted. "We have seen similar attacks in recent months taking advantage of the RevSlider Plugin and this could be linked to it." "Once the vulnerability has been exploited, the bad guys usually upload backdoors and shells designed to not only maintain control of the compromised website but also alter its core files, such as injecting iframes," he added. WordPress is one of the most popular - and most targeted - content management systems. In the case of the RevSlider attack, more than 100,000 WordPress websites were found to have been compromised. Segura suggested anyone running WordPress make sure their site and plugins are fully patched, and recommended people not log into their site from unsecure access points such as public Wi-Fis. The attack is ongoing, Segura said. Sursa: Cloned Pirate Bay Site Serving Malware | SecurityWeek.Com
