Rampant hacking Cryptocurrency insecurity DeFi is the worst hit

After the incident, Poly Network hackers had transferred nearly $100 million in DAI and USDC to the Curve stable coin pool, while transferring nearly $120 million worth of BUSD and USDC from the Coinan smart chain to the Curve fork project Ellipsis Finance.

After an overnight fermentation, on the morning of August 11, the hacker indicated through the on-chain transaction memo that he was ready to return the stolen assets, but wanted Poly Network to provide a multi-signature wallet because he could not contact Poly Network's project side.
