Maliciously crafted PDF files that opens door for trojan

MX Lab is detecting and intercepting an increased distribution of maliciously crafted PDF files. These PDF files contain an exploit that could result in a complete access to the infected computer and affects Windows XP or Windows 2003.

When the PDF document is opened the Windows firewall will be disabled by using Netsh, a command-line scripting utility that allows you to, either locally or remotely, display or modify the network configuration of a computer that is currently running. The code will start downloading a trojan from the internet which may allow the attacker to take control over the infected computer.
