Starting a week ago I am receiving emails with .jar files claiming to be from different Bitcoin sites. They don't get detected as spam by any spam filter, the jar file is not detected as a virus. It seems they are sent to handpicked targets who actively work with crypto currency. The emails came from 3 different sources so far, 3 via smtp.com (already talked to them and they said they will look into it), and 2 via gmail.

I will be running the jar file in a virus testing sandbox to see what network connections it tries to make. Decompiling the jar didn't give much result since I believe it contains native binaries (for osx, windows and linux) that are run. If anyone else received and already tested these files please let me know what you found.

I have accounts at almost every exchange (including Mt.Gox, though my email was not in the gox account lists I found on the net) so it could be that my email leaked from one of those.

Anyone else experiencing these?

This is a serious email attack that contains trojan to control your machine, not only windows machines but also linux and mac machines are targetted. More information can be found here https://bitcointalk.org/index.php?topic=652085.0

Do not download the file attached, otherwise your system will get compromised.
