A non-fungible token (NFT) auction on the MISO token launchpad built on the SushiSwap platform appears to have been hacked, with the attacker making off with roughly $3 million in ether, SushiSwap Chief Technology Officer Joseph Delong tweeted Thursday.
- Delong said that an anonymous contractor using the Github handle “AristoK3″ injected malicious code into Miso’s front end in a supply chain attack. He added the link to an Ethereum address showing ETH 864.8 transferred at approximately 16:00 UTC on Thursday.
- Etherscan has identified the address as part of an exploit.
- Supply chain attacks happen when a malicious actor changes a contract address to one they control. That type of attack can occur with open-source software libraries, according to the U.S. National Counterintelligence and Security Center.
- Only one contract appears to have been exploited, according to Delong, for the JayPegsAutoMart NFT sale.
- The attacker, who has done work with decentralized finance (DeFi) protocol yearn.finance, replaced the auction’s wallet address with their own, Delong said.
- Delong said SushiSwap “has reason to believe” the attacker was eratos1122, linking to a Twitter account that identifies as a blockchain and mobile games developer.
- SushiSwap has asked crypto exchanges FTX and Binance, to hand over the hacker’s know-your-customer information of the individual.
- CoinDesk hasn’t been able to independently verify the attacker’s identity as of press time.
- If the funds are not returned by 12:00 UTC, the DeFi exchange will file a complaint with the FBI, Delong said.
Hey folks. Everyone will still receive their 2007 Kia Sedona NFTs, and the exchange is still scheduled to begin on 9/21/2021. https://t.co/oYgqyHY8Jp

Stablecoin Adoption Is ‘Exploding' — Here's Why Wall Street Is Going All-In
Alchemy co-founder and president Joe Lau said stablecoin adoption is exploding as banks, fintechs and payment platforms push beyond the USDT/USDC exchange era.
What to know:
- Stablecoin usage is quickly broadening from crypto-native exchanges into payments, payroll and treasury as companies chase 24/7, digital-native settlement, according to Alchemy Co-founder and President Joe Lau.
- Banks are pushing tokenized deposits as a regulated, bank-native alternative that delivers stablecoin-like benefits for institutional clients.
- The endgame is a two-track system — stablecoins for open, two-party settlement; deposit tokens for bank ecosystems, until scale forces convergence and competition, Lau said.
