This week gambling group EOSBet had their Ethereum "DApp" hacked for 40,000 EOS cryptocoins ($200,000 USD) when hackers exploiting vulnerabilities in the app's smart contracts.
The hack comes as an embarrassment for the group, as they recently declared the app to be the safest and most secure around. The hackers reportedly found a glitch in the code, and used a transfer function to use a fake hash, which then tricked the EOSBet app into sending large amounts of the coin to various accounts.
In a statement to players an EOS representative wrote: "A few hours ago, we were attacked, and about 40,000 EOS was taken from our bankroll. This bug was not minor as was stated previously, and we are still doing forensics and piecing together what happened."
"[EOSBet] should be back online relatively quickly. We have narrowed down the bug to a faulty assertion statement in our code. After talking with other developers and BPs, it seems like other games were also attacked using this same exact code (abi forwarder.)"
Earlier in the week a punter reportedly won $600,000 on the site, although EOSBet claims that the win was legitimate and not part of the hacks that occurred with this incident.
Players should be wary of playing at EOSBet at this time, especially in light of the attack. It should be noted that we haven't had a chance to review the casino and are withholding judgment on whether or not they're legitimate until we've had the opportunity to conduct a thorough review.
