From the labs of F-Secure:
A new Warezov spam run is underway, using a “Happy New Year” postcard as its disguise.
The attachment is named postcard.zip and the text of the message reads:
Hi, you’ve just received a postcard.
For: (your e-mail address)
Text: Happy New Year!
Click on attachment to view a postcard.
When run, the malware connects to www6.easeruikingandefunjs.com and downloads a Warezov variant.
We detect this now as Trojan-Downloader.Win32.Small.edn.
