Pretty well designed attack. Its great you spreading knowledge, even if warning about 1 trojan threat from 500 out there, its spreading awareness about security.
Dont open unknown attachments or open/execute unknown files on your smartphone/PC.
This simplep rule won't get you infected that easily. It will protect from around 95% of threats i bet.
Did you know some program that blocks these kind of malware?. I'm afraid that some of those programs are not what we think it is. It is hard to know if that email is safe or not and which is why I don't open the emails I received. Until now, I have lots of emails that I received and haven't open any of it except the important ones and the ones I know. @Op: thanks a lot for spreading this kind of malware and how it works.
