Got a round of these in my inbox this morning. These are EXEs being spammed out in e-mail messages to get you to install malware. The names of Hollywood stars used in the emails include Nicole Kidman, Angelina Jolie, and Natalie Portman.
Here’s a sample email:

Good evening, man!
Shocking pictures of nude Nicole Kidman. See it in your attachment.
[ Part 2, Application/ZIP 26KB. ]
[ Cannot display this part. Press "V" then "S" to save in a file. ]
The attachment, “amazing.zip”, contains “shocking.exe”.Analyzing the malware reveals that the malware installs a rootkit via a hooked TCP/IP driver:
Once executed, shocking.exe will delete itself. It will also use Internet Explorer to download files from the following IP addresses (all on TCP port 80): 184.108.40.206, 220.127.116.11, 18.104.22.168, 22.214.171.124, and 126.96.36.199. It downloads a binary that appears to be used in spamming. It will also install a registry key, RegistryMachineSystemCurrentControlSetServicesip6fw, as one of the means to ensure it runs.
Detection is weak at this point.
