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.

MP3 based stock spam outbreak

After the PDF, Excel and ZIP based spam outbreaks we now have a stock spam outbreak based on the popular MP3 format for delivering audio. The messages are between 85kB and 150kB and contain an MP3 in poor quality at a 16 kbps bitrate and 11 KHz sample rate with an average length of 30 seconds. To avoid email filters these files are highly randomized.

The attachment files names range from well known artists like smashingpumpkins.mp3, bbrown.mp3, bspears.mp3, gloriaestefan.mp3, beatles.mp3 to and some obvious poplar sound names like answeringmachine.mp3, coolringtone.mp3, listentothis.mp3. The subject only contains Fwd: or Re:.

MX Lab protects clients against this new form of spam. The outbreak accounts for around 7-10% of all spam, globally, over the past 18 hours. The first MP3 spams where detected on October 17, 2007, 21:24 GMT.
