Polychain-backed DFX Finance hacked for $7.5 million
DFX Finance, a decentralized exchange protocol for fiat-pegged stablecoins, reported that it was attacked at 2:21 pm ET. An unknown attacker siphoned approximately $7.5 million from DFX, according to estimates from security researchers at BlockSec. The DFX Finance team acknowledged the security exploit and said it has paused all of its smart contracts to contain the issue. “We were notified of the suspicious activity within 20-30 mins of the first transaction and executed a pause on all DFX contracts within a few minutes after confirming the attack,” it said. The remaining portion of the stolen assets — about $3.2 million — was extracted by an MEV bot in a front-running transaction, also called a sandwich attack.
