SEI blockchain suffered a $240,000 flash loan attack; a user’s accidental transfer of funds triggered the vulnerability.

PANews reported on January 9th that, according to BlockSec Phalcon monitoring, an attacker initiated a flash loan on the SEI chain via a Synnax contract, borrowing 1.96 million WSEI tokens (approximately $240,000) and failing to repay it. This attack was triggered by a misoperation three blocks prior: address 0x9748…a714 mistakenly transferred funds into the contract, inadvertently providing funding for the attack. The attack path involved TX1 and TX2 transactions, demonstrating that on-chain misoperations can still pose a critical risk in DeFi attacks.
