Networked arcade machines, while providing enhanced gaming experiences through connectivity features, face several significant security vulnerabilities that operators must address. The most prevalent threats include physical security weaknesses where attackers can directly access internal components through poorly secured cabinet panels or service doors. Network-based attacks represent another major concern, as many arcade systems operate on inadequately protected networks, making them susceptible to unauthorized access, data interception, and man-in-the-middle attacks. Outdated software and firmware create additional risks, with unpatched systems vulnerable to known exploits that can compromise game integrity and payment systems. Malware infections specifically targeting arcade platforms can disrupt operations, steal player data, or even cryptocurrency mining in extreme cases. Payment system vulnerabilities present serious financial risks, including skimming devices, compromised card readers, or manipulation of coin mechanisms. Many arcade machines also suffer from insufficient authentication protocols, allowing unauthorized access to administrative functions and configuration settings. The integration with online leaderboards and cloud services introduces web application vulnerabilities that can be exploited to manipulate scores or access user data. To mitigate these risks, operators should implement comprehensive physical security measures, maintain regular software updates, employ network segmentation, conduct security audits, and establish robust monitoring systems to detect and respond to potential threats promptly.
