RBN 

(n.) Acronym for Russian Business Network, a large-scale, organized cybercrime organization specializing in the sale of stolen identities.

I think I know how my bank account got hijacked--I might have accidentally logged into a phishing site on the RBN. That explains why the URL ended in ".ru".
