Security experts are concerned about the launch of another malicious software program that purports to be an installer file for Skype.  The malware sends the chosen user’s Skype credentials and any other logins or passwords stored in Internet Explorer to another server. 

This latest Trojan horse appears as an installer with the Skype logo and the name "65404-SkypeDefenderSetup.exe." Once the user clicks on the program, users see a look-alike Skype login interface asking for login credentials.

While users can then enter login credentials, none of the other menu functions work. The Skype Trojan has been circulating through spam and through IM conversations that contain a link to the malware.  It is not self-propagating but instead relies on humans to send it to each other.  Once again, this is yet another reason to not open e-mail with attachments from others that are not well known.
