A really bad spam mail...

A really bad spam mail...  Got this one last night:

Dear

NB: Open the attach file with java application.

Hope to hear from you soon.

Regards.

Attached is a file named “331,000 $ SWIFT.jpg.jar”

Obviously, I did not run that jar file.  For the non-geeks out there, a “jar” file contains a program written in Java that can do just about any damn thing it wants to on your system.  Running a jar file that you got from someone you don't know is a really, really bad idea.  It could ruin your whole day.  Actually, a lot of whole days...

There are enough red flags for anyone reading this (poor English, missing name, unlikely monetary pitch, etc.) that I think it's unlikely they'll fool many people.  At least, I hope that's the case!  On the other hand, I can imagine that there are a lot of people who don't realize that running a jar file can do really bad things...
