John Dixon describes the tactics used by Eastern European criminal organizations to steal money from U.S. companies through wire transfer fraud. He shares an anecdote about a water utility company that lost funds after a payment processor's computer was compromised by a botnet. Dixon explains the difficulty of prosecution when attackers use multiple "hops" through shell accounts in different jurisdictions to cover their tracks.

John Dixon explains the differences between the "closed" Apple iOS ecosystem and the more "open" Android platform regarding security. He points out that users often rely on brand trust (e.g., a bank's logo) as a proxy for security because there is no independent auditing or rating system for mobile apps. Dixon notes that Apple's app review process focuses more on competition and content than on detecting sophisticated backdoors.
