Ever read through your spam sometimes to see what's popular? Of course you may also get a fresh serving of malware, which makes it very worthwhile. "Hi, remember me?..
new fotos(archived) you asked ;))

kiss,
Angella O."

Well, no I don't remember an Angella that I have met recently, particularly not someone who might send me photos. But I'll bite. A simple wget scores me an exe. Virustotal results are depressingly consistent. 4/32.

So, only generic detection when the file was first seen, how about 12 hours later? Nope, same results.
