Blizz Finance Hack

TOTAL LOST $8.3M
Medium Oracle Manipulation & Price Manipulation Avalanche C-Chain

What happened

During the Terra collapse, Blizz Finance's Avalanche lending market was drained for roughly $8.3 million after its LUNA/USD oracle stopped updating at $0.10 while LUNA traded far below that value.

Technical Root Cause

The Aave-v2-derived oracle integration had no protocol-level safeguard for Chainlink's LUNA minimum-answer circuit breaker or for stale and invalid price data. The protocol also lacked an emergency response path fast enough to disable the LUNA market.

Attack Timeline

Several addresses bought or held severely devalued LUNA, deposited it as collateral at the stale $0.10 oracle value, and borrowed the market's available assets. Because Blizz could not pause immediately, its timelock delayed the response until liquidity had been exhausted.
