Anti-spam vendor FrontBridge Technologies Inc. has identified the top 10 deceptive E-mail subject lines used by spammers to lure recipients into opening their messages. FrontBridge's list was culled from 1,200 enterprise E-mail domains the company filters and analyzes regularly, and the vendor expects more E-mail containing such deceptive subject lines to appear in in-boxes. It reports that deceptive spam tactics grew more than 50% in the first six months of the year.
