VERY IMPORTANT

Recently, the FortiGuard Labs research team observed that a new variant of Poison Ivy was being spread through a compromised PowerPoint file. We captured a PowerPoint file named Payment_Advice.ppsx, which is in OOXML format. Once the victim opens this file using the MS PowerPoint program, the malicious code contained in the file is executed. It downloads the Poison Ivy malware onto the victim’s computer and then launches it. In this blog, I’ll show the details of how this happens, what techniques are used by this malware, as well as what it does to the victim’s computer.
