For DeFi, the last week of 2022 saw another slew of exploits, insider job accusations and exit scam drama. It all started on Christmas, when Defrost Finance, a decentralized leveraged trading platform on the Avalanche blockchain, was exploited by a DeFi flash loan attack causing $12 million in losses.

However, the hacker behind the attacks reportedly returned a portion of the funds the next day. Security analytic firm Certik looked into the chain of events and concluded that the $12 million of funds drained were a part of an exit scam.

On Dec. 26, when the Defrost exploit saga was unfolding, Bitkeep, a multichain wallet, was exploited for $8 million by hackers. Later in an analysis report, it emerged that exploiters lured users through phishing websites.
