A new malware reversing challenge from Halvar Flake.

Submissions will only be accepted from female reverse engineers, but that doesn't mean guys can't enjoy it as well.

Now this is an ongoing challenge, so no spoilers. All I will say is that I found the ms_ehseh.idc IDA script from the following link very useful to get started. That should give you some idea of what you're getting into.
