EOSPlay

EOSPlay, also known as EOS Gambling Game, operates as a blockchain-based betting platform utilizing the EOS blockchain. Its core service involves facilitating gambling activities where participants wager the EOS cryptocurrency. The platform leverages the decentralized nature of blockchain technology for transaction processing within its gambling games. Headquarters for the organization are located in Panama.

A significant incident in September 2019 exposed vulnerabilities associated with the platform's interaction with EOS blockchain resources. A hacker exploited an alleged bug by utilizing EOS REX, a decentralized finance service on the EOS network. This manipulation allowed the attacker to secure continuous wins on the EOSPlay platform. The hacker spent approximately $1,000 worth of resources but successfully stole around 30,000 EOS, valued at over $110,000 at the time. This attack caused substantial network congestion on the EOS blockchain. Conflicting reports emerged regarding the severity of the congestion; some users reported disruptions to decentralized applications and wallets due to CPU resource exhaustion, while network representatives stated the core operations continued despite bandwidth overload. The incident highlighted potential risks in the platform's design and its reliance on underlying blockchain mechanisms. Notably, despite the security breach and associated network issues, the price of the EOS cryptocurrency experienced a significant increase during the period surrounding the attack.
