I'm starting to see a malware attack against Macs turning up in my email inbox. These look like fairly standard ecards from American Greetings or Yahoo Greetings. The email body copy reads:
"You've just received a Yahoo! Exclusive e Card via AmericanGreetings. com

The link LOOKS like it goes to American Greetings, but it actually leads to ecardg (dot) ggreetcards (dot) com. When you arrive there, you're asked to download the PowerPoint plugin if your browser doesn't have it. The site then attempts to download malware.
This site recognizes Mac and Windows browsers, and downloads malware for each--it's not a Windows-only threat.
