A new TROJ_YABE variant is currently making the rounds in the net. We managed to get a copy of the sample email. Please see below.
The email is in German and since I dont read German, a babel fish translation of the email body is found below.———————————————-

As you probably may have already guessed this malware diguises itself as a pdf document in order to fool users to making them execute the attachment.
The email attachment is Ebay.pdf.exe with a pdf icon as shown below.
As part of its social engineering techniques, Ebay.pdf.exe pops up a message box that says an error has occured in Acrobat 6 making the user believe that the attachment is just a corrupted pdf file and not a trojan.
Unknown to the user, the file Ebay.pdf.exe has already connected to the internet and has downloaded a txt file from one either one of these locations:
These txt files contain an encrypted copy of a URL of another trojan filenamed 6.exe which will be downloaded by Ebay.pdf.exe. This in turn drops a BHO spyware.
