For those who’ve been wondering where I’ve been, I’m still off celebrating my Silver Wedding Anniversary. This however is an emergency.
I was on Facebook a few minutes ago, and a distant cousin popped up a chat window, with a link to a picture. Alarm bells immediately went off. No chat, just a link to a picture? That just wasn’t right. I was pretty sure it was a virus. I was also certain I was safe, as I know he runs Windows.
So I clicked on it, and the image didn’t open, which is what should have happened since I was using my Mac. Instead it downloaded a zip file.
Here’s what Facebook chat said:
Note that I killed the link so no one could accidentally click on it. After downloading it I unzipped it, and this is what I saw.
I then opened it with an editor, and confirmed that it was a Windows only payload.
As I’ve warned people before, if you avoid Windows, you will avoid most of the malware in existence. Yes, there is a small amount of malware that exists for Linux and Mac OS X. I still have a copy of the Mac malware I wrote about several months back on my hard drive. It’s really not very impressive compared with this, which from what I can tell appears to self install with only one click from the Windows user.
If you know anyone who is running Windows, warn them that they really need to make sure that they have something installed to keep them safe. My personal suggestion is that Microsoft’s solution is worth looking at.
