PA diagram | A quick overview of large-scale cross-chain bridge attacks and how they were handled

Cross-chain bridge security incidents are frequent, with more than $2 billion historically involved. According to incomplete statistics from PANews, 2022 is the most frequent year for cross-chain bridge theft, although it has decreased this year, but this month, two well-known cross-chain bridges, Poly Network and Multichain, have been stolen or funds have been abnormally transferred, and the probability of funds being recovered or paid out in recent cross-chain bridge security incidents has decreased.
