Online poker is a multi-million dollar industry that is rapidly growing, but is not highly regulated. There have been "hacks" recently (i.e. weak SSL implementation, superuser account) that have drawn more attention to security in the poker industry, especially as it moves to full regulation in the United States. This talk will cover the technical architecture of online poker, existing security controls, examples of past vulnerabilities, new weaknesses we have discovered in the poker clients and surrounding infrastructure, and next steps of research we are performing in this area.
