in my experienceOne of the core scams is getting someone like myself to hand over user names and passwords and other vital bits of data under the guise that my HR department needs to update their records, or that an account is about to expire. Some people even go thru the effort to build elaborate and physically (ie, the UI) accurate scam sites to fool the user into going thru a re-registration process that snarfs the desired data.
I have also been getting many more .exe and .bat file extension files recently at my MacConnect email account. This is one of the core reasons why I am a Mac user, WAY fewer virii. It's the social engineering and thought virii that you have to watch out for. The pure Japanese spams can be pretty confusing too...
