I was pleased to note that the message originated from Yahoo, and contained several classic red flags for spam that even the neophyte mail server admin knows to watch out for, like from & reply-to headers with different different domains. This is the kind of l33t security I've come to expect from Yahoo. But hey, the Russians did it, and no one can be expected to secure their customers from state sponsored attacks. Susan here is no doubt a member of Nigeria's elite NIA.
