What is the Arkansas list from Ashley Madison?

The Arkansas list from Ashley Madison refers to a subset of data that was released in a massive data breach of the Ashley Madison website in July 2015. Ashley Madison, a site designed to facilitate extramarital affairs, was targeted by hackers who threatened to release user information if the site was not shut down. The hackers made good on their threat and published vast amounts of user data online. This included account details, email addresses, payment transactions, and other personal information. The Arkansas list specifically contained information related to users from the state of Arkansas. The implications of this breach were significant, as they exposed private details of individuals' lives and opened them up to potential public scrutiny, embarrassment, and other personal and professional consequences.
