Italian Internet Mafia

Just returned from Italy, where I attended NSPW and spent a few days on the beaches of Rimini. It seems the Italian Internet Mafia is after me: I just received a load of malware in an e-mail message colorably coming from Banca Popolare dell’Emilia Romagna – Emilia-Romagna was my destination region – and asking me in italian to open an attachment. I really wonder where they harvested my e-mail address. Any idea?
