I want to sue Homeaway.com for a security breach that resulted in a fraudulent transaction.

Homeaway.com is the largest online company that specializes in vacation rentals. Owners pay homeaway.com a fee to list properties for rent. I reached out to an owner on Homeaway.com for a rental property. After an agreement with the owner, and funds transferred, I found out that I was scammed. The rental listing was hacked and an impostor posing as the owner was communicating directly with potential renters. Homeaway notified me after funds were transferred that the rental listing had security concerns. At that point it was to late to reverse the transaction. I lost a total of $8500 and feel homeaway.com was negligent in protecting potential renters. I had a conversation with the true owner afterwards and he mentioned that others were also scammed.
