DDEX is a decentralized exchange platform in the process of expanding into decentralized lending so that they can offer their users the ability to create leveraged long and short positions. They're currently beta testing their decentralized margin exchange. A Peckshield alert shows that XDX Swap on DDEX, a cross-chain decentralized exchange on the Heco chain, was attacked. The attacker made a profit of 85.17 ETH (approximately $176,000). At present, the attacker has transferred all the profits across the chain to Ethereum. From July 1st to 2nd, the HECO ecological chain project XDX Swap (DDEX) was attacked by hackers, and various digital virtual currencies worth more than 5 million U.S. USD in the fund pool were stolen. A node governance maneuver allowed the funds to be returned from the attacker's wallet.

[T]he DdeX code is suspected to have a backdoor. The DDEX project party and the HECO White Hat Security Network Alliance team confirmed that the attack was due to a vulnerability in the project's smart contract code. The attacker used the vulnerability to steal user assets stored in the fund pool.
