Sophos has posted an article about a Trojan dropper which comes from an email.  The email consists of five sentences and it is about a woman who wants to connect with the recipient.

There is an attachment labeled photo.zip. Fraser Howard, the author of the blog entry at Sophos, notes that the attachment contains a malicious Trojan dropper and it has been detected as Troj/Mdrop-BUP.

If the recipient runs the attached file, he or she will see a picture of a girl and their desktop background will be changed to display a fake warning message. Then, two pieces of malware will be installed.
