  "description": "On Oct 27 2026 (about 00:00 UTC Oct 28) an attacker drained 1,013,353.61 USDC from a Tranche Vault on Avalanche that Blockaid linked to Fence Finance and Valinor Digital. Blockaid said the attacker used a flash loan to mint inflated tranche shares and then redeemed the vault's remaining USDC across about two transactions; a later balance check showed no USDC left in the vault contract. The stolen funds were bridged to Solana. Neither Fence Finance nor Valinor Digital had published a statement, and whether the vault was paused or fixed was unconfirmed.",
