To kick off SC Magazine's revamped podcast series, Executive Editor Dan Kaplan speaks with Kirill Levchenko, a project scientist at the University of California, San Diego, who is co-author of a new research paper that investigates the payment handling portion of the spam chain. Levchenko and 14 others argue in the paper that much of the anti-spam focus over the years has been on technical controls when, in fact, hitting the spammers and their affiliates where it hurts the most -- in their pockets -- may be the best approach.
