Xscope: Hunting for Cross-Chain Bridge Attacks. (arXiv:2208.07119v1 [cs.SE])

Cross-Chain bridges have become the most popular solution to support asset
interoperability between heterogeneous blockchains. However, while providing
efficient and flexible cross-chain asset transfer, the complex workflow
involving both on-chain smart contracts and off-chain programs causes emerging
security issues. In the past year, there have been more than ten severe attacks
against cross-chain bridges, causing billions of loss. With few studies
focusing on the security of cross-chain bridges, the community still lacks the
knowledge and tools to mitigate this significant …
