Bridge Exploit attacks on Base

An attacker minted 19 million unbacked THEO on Base through Autheo's Hyperlane cross-chain route and swapped them for about 700 ETH, crashing the token roughly 92%.

An attacker fed Allbridge's Base router a forged Circle CCTP message and padded it with an Aave flash loan to drain about $190,000 in USDC that a real deposit had just credited.

1B bridged DOT minted on Hyperbridge after a missing bounds check in VerifyProof let an attacker forge MMR proofs; realised loss ~$2.5M.
