Blockchain security firm PeckShield said at least eight major security incidents involving cross-chain bridges resulted in about $328.6 million in stolen funds between February 2026 and mid-May 2026, underscoring persistent risks in multi-chain infrastructure. One of those incidents was the Adshares bridge exploit on May 17, 2026, which caused about $628,000 in losses. PeckShield later reported that the attacker returned 256 ETH, worth about $540,700, to a project deployment address, recovering roughly 86% of the stolen amount. The developments highlight both the recurring vulnerability of bridge systems, which move assets between blockchains and often hold concentrated liquidity, and the partial recovery in a specific case.
