Data breaches in online casino payment systems can have severe implications for both operators and players, leading to financial losses, reputational damage, and legal consequences. When sensitive information such as credit card details, personal identification, or account credentials is compromised, players may face identity theft or unauthorized transactions, resulting in a loss of trust in the casino's ability to protect their data. For operators, a breach can lead to costly remediation efforts, potential lawsuits from affected customers, and hefty fines from regulatory authorities for failing to adhere to data protection regulations.
