Attacks against sites running older versions of the content management system, 4.2 and earlier, were spotted by Zscaler. Those sites are backdoored and redirect a victim’s browser through iframes to a landing page hosting the exploit kit where a Flash exploit awaits. The exploits generally target Internet Explorer, Zscaler said, and victims’ computers are eventually infected with CryptoWall 3.0 ransomware.
This analysis is in line with a similar report from the SANS Institute, which pointed the finger at a particular cybercrime group that had steered away from using the prolific Angler Exploit Kit and moved operations to Neutrino.
