New java dropped malware

We are investigating the report from one of our colleagues, reporting one website dropped malicious exe files by some java exploit, possibly an already known one. Of course, this is not “that” important, but keep in touch on this:

Inside the jar

Thanks for the info, K.T. (Cuby).
