Avalanche hacks in 2026

An attacker hijacked a Binance Ethereum hot wallet via an EIP-7702 delegation and swept an estimated $6.3 billion across several chains — the largest theft in crypto history.

A flash-loan attacker inflated vault share accounting to drain about 1.01 million USDC from an Avalanche Tranche Vault linked to Fence Finance and Valinor Digital.

A stale, unrevoked token approval let an attacker drain ~$7.45M from a 2-of-7 Safe multisig on Avalanche, but a MEV bot front-ran the theft and returned most funds.
