Maiar decentralized crypto exchange goes offline after bug discovery
Minutes before 12 a.m. UTC on June 6, the CEO and co-founder of the Elrond Network, Beniamin Mincu, tweeted that he and his team were “investigating a set of suspicious activities” on the Maiar decentralized crypto exchange (DEX).
Soon after the exchange was taken offline with Mincu reporting the issue was identified and an “emergency fix” was being implemented.
In a Twitter thread posted almost 24 hours later around 11 p.m. UTC on June 6, Mincu said a potentially critical bug was identified which opened “an exploit area that we simply had to address and mitigate immediately.”
The suspicious activities have been possibly identified and explained in a Twitter thread by pseudonymous on-chain analyst “Foudres” who revealed the potential attacker deployed a smart contract that somehow allowed them to withdraw over 1.65 million Elrond (EGLD).
Three wallets were able to mysteriously withdraw 800,000, 400,000 and 450,000 EGLD respectively which at current prices would in total be worth nearly $113 million.
The attackers were able to sell around 800,000 EGLD worth around $54 million which caused the price of EGLD on the Maiar DEX to plummet from $76 down to around $5. The rest of the crypto is either still held in various wallets, has been bridged to USD Coin (USDC) and Ether (ETH), or was sold on centralized exchanges.
The price of EGLD dropped 9.5% from around $74 down to a 24-hour low of $65.50, but has since slightly recovered now trading near $68.
Mincu stated in his update that an upgrade was implemented to fix the bug and that a technical explanation would be provided after clarification that the implemented solutions are tested and working.
