Recent hacks of EOS-based gambling platforms have resulted in the theft of over $250,000 worth of EOS coins.

The EOSBet online casino, through its Reddit account, announced that a hack had occurred last Friday, where 44,427.4302 EOS (about $240,000) were stolen, “before our contracts were taken offline by the development team. The remaining 463,745 EOS in our EOSBETDICE11 and EOSBETCASINO contracts are safe, the vulnerability is patched, and we are back online. We want to be as transparent as possible in explaining this breach and addressing any concerns the community might have.”

According to EOSBet, the hacker was able “to place bets without transferring EOS to the contract. For losses, he was paid nothing, but lost nothing. However, for wins he was paid out real EOS from the contract.”

EOSBet admitted that in spite of multiple audits before the attack, “there was still a vulnerability in our smart contract. The task moving forward is to strengthen our security practices, ensuring that a similar event does not occur in the future.”
