Curiouser and curiouser.
TripAdvisor.com reported a breach on March 24. At the time, some sources suggested it was a SQL injection, although I mentioned that there was some possibility it was due to a breach at an email service provider. Now TripAdvisor.com has sent out notices that they have been affected by the Epsilon breach. CORRECTION: The breach report I had been sent supposedly related to Epsilon was the March 24th notice which is not Epsilon. My apologies to Epsilon and TripAdvisor.
