An unsecured ElasticSearch database was discovered exposing the details for over 108 million bets at various online casinos. The exposed data included the personal information of a bettor, the affiliates who referred them to the site, their balances, deposits, withdrawals, and bets. This information could have been used to scam individuals, perform identity theft, or to try and gain access to the user’s accounts via social engineering. It is not known who managed the database, but many of the referenced casinos operate under a parent company based out of Cyprus.
