In a concerning trend for the decentralized finance, or DeFi space, two prominent protocols – Exactly and Harbor – have fallen victim to separate attacks. These incidents, the latest in a string of recent exploits, have highlighted the vulnerabilities that can arise within the relatively new and experimental world of DeFi.

Exactly, a credit market operating on the Optimism network, clearly did not see it coming. The attack, first uncovered by blockchain security firm DeDotFi, involved hackers exploiting a weakness in Exactly’s smart contracts. Security firm PeckShield said on X (formerly Twitter) that it had “detected an ongoing attack.”

Update: After a thorough review of the Exactly Protocol Hack, we have concluded that the total of stolen amount up to date is ~$7.2M (4323.6 $ETH)
