What happened
On March 15-16, 2022, an attacker exploited a reentrancy vulnerability in Hundred Finance's callback handling to borrow $6 million across multiple markets. The attacker deposited ~$2M USDC collateral, then repeatedly borrowed against it via the onTokenTransfer() callback which triggered before debt was updated.
In review: sources disagree on the loss.
